The value of this property should be a string representing a path + to another object or a custom binding instanced created using Binding helpers + (see "One Way Bindings"): + + ``` + valueBinding: "MyApp.someController.title" + ``` + + This will create a binding from `MyApp.someController.title` to the `value` + property of your object instance automatically. Now the two values will be + kept in sync. + + ## One Way Bindings + + One especially useful binding customization you can use is the `oneWay()` + helper. This helper tells Ember that you are only interested in + receiving changes on the object you are binding from. For example, if you + are binding to a preference and you want to be notified if the preference + has changed, but your object will not be changing the preference itself, you + could do: + + ``` + bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles") + ``` + + This way if the value of `MyApp.preferencesController.bigTitles` changes the + `bigTitles` property of your object will change also. However, if you + change the value of your `bigTitles` property, it will not update the + `preferencesController`. + + One way bindings are almost twice as fast to setup and twice as fast to + execute because the binding only has to worry about changes to one side. + + You should consider using one way bindings anytime you have an object that + may be created frequently and you do not intend to change a property; only + to monitor it for changes (such as in the example above). + + ## Adding Bindings Manually + + All of the examples above show you how to configure a custom binding, but the + result of these customizations will be a binding template, not a fully active + Binding instance. The binding will actually become active only when you + instantiate the object the binding belongs to. It is useful however, to + understand what actually happens when the binding is activated. + + For a binding to function it must have at least a `from` property and a `to` + property. The `from` property path points to the object/key that you want to + bind from while the `to` path points to the object/key you want to bind to. + + When you define a custom binding, you are usually describing the property + you want to bind from (such as `MyApp.someController.value` in the examples + above). When your object is created, it will automatically assign the value + you want to bind `to` based on the name of your binding key. In the + examples above, during init, Ember objects will effectively call + something like this on your binding: + + ```javascript + binding = Ember.Binding.from(this.valueBinding).to("value"); + ``` + + This creates a new binding instance based on the template you provide, and + sets the to path to the `value` property of the new object. Now that the + binding is fully configured with a `from` and a `to`, it simply needs to be + connected to become active. This is done through the `connect()` method: + + ```javascript + binding.connect(this); + ``` + + Note that when you connect a binding you pass the object you want it to be + connected to. This object will be used as the root for both the from and + to side of the binding when inspecting relative paths. This allows the + binding to be automatically inherited by subclassed objects as well. + + Now that the binding is connected, it will observe both the from and to side + and relay changes. + + If you ever needed to do so (you almost never will, but it is useful to + understand this anyway), you could manually create an active binding by + using the `Ember.bind()` helper method. (This is the same method used by + to setup your bindings on objects): + + ```javascript + Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value"); + ``` + + Both of these code fragments have the same effect as doing the most friendly + form of binding creation like so: + + ```javascript + MyApp.anotherObject = Ember.Object.create({ + valueBinding: "MyApp.someController.value", + + // OTHER CODE FOR THIS OBJECT... + }); + ``` + + Ember's built in binding creation method makes it easy to automatically + create bindings for you.

The last argument is + required to be an options object. The options object can have the + following four properties: + + `initialValue` - A value or function that will be used as the initial + value for the computed. If this property is a function the result of calling + the function will be used as the initial value. This property is required. + + `initialize` - An optional initialize function. Typically this will be used + to set up state on the instanceMeta object. + + `removedItem` - A function that is called each time an element is removed + from the array. + + `addedItem` - A function that is called each time an element is added to + the array. + + + The `initialize` function has the following signature: + + ```javascript + function (initialValue, changeMeta, instanceMeta) + ``` + + `initialValue` - The value of the `initialValue` property from the + options object. + + `changeMeta` - An object which contains meta information about the + computed. It contains the following properties: + + - `property` the computed property + - `propertyName` the name of the property on the object + + `instanceMeta` - An object that can be used to store meta + information needed for calculating your computed. For example a + unique computed might use this to store the number of times a given + element is found in the dependent array. + + + The `removedItem` and `addedItem` functions both have the following signature: + + ```javascript + function (accumulatedValue, item, changeMeta, instanceMeta) + ``` + + `accumulatedValue` - The value returned from the last time + `removedItem` or `addedItem` was called or `initialValue`. + + `item` - the element added or removed from the array + + `changeMeta` - An object which contains meta information about the + change. It contains the following properties: + + - `property` the computed property + - `propertyName` the name of the property on the object + - `index` the index of the added or removed item + - `item` the added or removed item: this is exactly the same as + the second arg + - `arrayChanged` the array that triggered the change. Can be + useful when depending on multiple arrays. + + For property changes triggered on an item property change (when + depKey is something like `someArray.@each.someProperty`), + `changeMeta` will also contain the following property: + + - `previousValues` an object whose keys are the properties that changed on + the item, and whose values are the item's previous values. + + `previousValues` is important Ember coalesces item property changes via + Ember.run.once. This means that by the time removedItem gets called, item has + the new values, but you may need the previous value (eg for sorting & + filtering). + + `instanceMeta` - An object that can be used to store meta + information needed for calculating your computed. For example a + unique computed might use this to store the number of times a given + element is found in the dependent array. + + The `removedItem` and `addedItem` functions should return the accumulated + value. It is acceptable to not return anything (ie return undefined) + to invalidate the computation. This is generally not a good idea for + arrayComputed but it's used in eg max and min. + + Note that observers will be fired if either of these functions return a value + that differs from the accumulated value. When returning an object that + mutates in response to array changes, for example an array that maps + everything from some other array (see `Ember.computed.map`), it is usually + important that the *same* array be returned to avoid accidentally triggering observers. + + Example + + ```javascript + Ember.computed.max = function (dependentKey) { + return Ember.reduceComputed.call(null, dependentKey, { + initialValue: -Infinity, + + addedItem: function (accumulatedValue, item, changeMeta, instanceMeta) { + return Math.max(accumulatedValue, item); + }, + + removedItem: function (accumulatedValue, item, changeMeta, instanceMeta) { + if (item < accumulatedValue) { + return accumulatedValue; + } + } + }); + }; + ``` + + Dependent keys may refer to `@this` to observe changes to the object itself, + which must be array-like, rather than a property of the object.

The last argument is + required to be an options object. The options object can have the + following three properties. + + `initialize` - An optional initialize function. Typically this will be used + to set up state on the instanceMeta object. + + `removedItem` - A function that is called each time an element is + removed from the array. + + `addedItem` - A function that is called each time an element is + added to the array. + + + The `initialize` function has the following signature: + + ```javascript + function (array, changeMeta, instanceMeta) + ``` + + `array` - The initial value of the arrayComputed, an empty array. + + `changeMeta` - An object which contains meta information about the + computed. It contains the following properties: + + - `property` the computed property + - `propertyName` the name of the property on the object + + `instanceMeta` - An object that can be used to store meta + information needed for calculating your computed. For example a + unique computed might use this to store the number of times a given + element is found in the dependent array. + + + The `removedItem` and `addedItem` functions both have the following signature: + + ```javascript + function (accumulatedValue, item, changeMeta, instanceMeta) + ``` + + `accumulatedValue` - The value returned from the last time + `removedItem` or `addedItem` was called or an empty array. + + `item` - the element added or removed from the array + + `changeMeta` - An object which contains meta information about the + change. It contains the following properties: + + - `property` the computed property + - `propertyName` the name of the property on the object + - `index` the index of the added or removed item + - `item` the added or removed item: this is exactly the same as + the second arg + - `arrayChanged` the array that triggered the change. Can be + useful when depending on multiple arrays. + + For property changes triggered on an item property change (when + depKey is something like `someArray.@each.someProperty`), + `changeMeta` will also contain the following property: + + - `previousValues` an object whose keys are the properties that changed on + the item, and whose values are the item's previous values. + + `previousValues` is important Ember coalesces item property changes via + Ember.run.once. This means that by the time removedItem gets called, item has + the new values, but you may need the previous value (eg for sorting & + filtering). + + `instanceMeta` - An object that can be used to store meta + information needed for calculating your computed. For example a + unique computed might use this to store the number of times a given + element is found in the dependent array. + + The `removedItem` and `addedItem` functions should return the accumulated + value.

You + can create a set to efficiently test for membership for an object. You can + also iterate through a set just like an array, even accessing objects by + index, however there is no guarantee as to their order. + + All Sets are observable via the Enumerable Observer API - which works + on any enumerable object including both Sets and Arrays. + + ## Creating a Set + + You can create a set like you would most objects using + `new Ember.Set()`. Most new sets you create will be empty, but you can + also initialize the set with some content by passing an array or other + enumerable of objects to the constructor. + + Finally, you can pass in an existing set and the set will be copied. You + can also create a copy of a set by calling `Ember.Set#copy()`. + + ```javascript + // creates a new empty set + var foundNames = new Ember.Set(); + + // creates a set with four names in it. + var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P + + // creates a copy of the names set. + var namesCopy = new Ember.Set(names); + + // same as above. + var anotherNamesCopy = names.copy(); + ``` + + ## Adding/Removing Objects + + You generally add or remove objects from a set using `add()` or + `remove()`. You can add any type of object including primitives such as + numbers, strings, and booleans. + + Unlike arrays, objects can only exist one time in a set. If you call `add()` + on a set with the same object multiple times, the object will only be added + once. Likewise, calling `remove()` with the same object multiple times will + remove the object the first time and have no effect on future calls until + you add the object to the set again. + + NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do + so will be ignored. + + In addition to add/remove you can also call `push()`/`pop()`. Push behaves + just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary + object, remove it and return it. This is a good way to use a set as a job + queue when you don't care which order the jobs are executed in. + + ## Testing for an Object + + To test for an object's presence in a set you simply call + `Ember.Set#contains()`. + + ## Observing changes + + When using `Ember.Set`, you can observe the `"[]"` property to be + alerted whenever the content changes. You can also add an enumerable + observer to the set to be notified of specific objects that are added and + removed from the set. See [Ember.Enumerable](/api/classes/Ember.Enumerable.html) + for more information on enumerables. + + This is often unhelpful. If you are filtering sets of objects, for instance, + it is very inefficient to re-filter all of the items each time the set + changes. It would be better if you could just adjust the filtered set based + on what was changed on the original set. The same issue applies to merging + sets, as well. + + ## Other Methods + + `Ember.Set` primary implements other mixin APIs. For a complete reference + on the methods you will use with `Ember.Set`, please consult these mixins. + The most useful ones will be `Ember.Enumerable` and + `Ember.MutableEnumerable` which implement most of the common iterator + methods you are used to on Array. + + Note that you can also use the `Ember.Copyable` and `Ember.Freezable` + APIs on `Ember.Set` as well. Once a set is frozen it can no longer be + modified. The benefit of this is that when you call `frozenCopy()` on it, + Ember will avoid making copies of the set.

to change what's displayed, simply swap out the + `content` property on the controller. + + For example, imagine you wanted to display a list of items fetched via an XHR + request. Create an `Ember.ArrayController` and set its `content` property: + + ```javascript + MyApp.listController = Ember.ArrayController.create(); + + $.get('people.json', function(data) { + MyApp.listController.set('content', data); + }); + ``` + + Then, create a view that binds to your new controller: + + ```handlebars + {{#each MyApp.listController}} + {{firstName}} {{lastName}} + {{/each}} + ``` + + Although you are binding to the controller, the behavior of this controller + is to pass through any methods or properties to the underlying array. This + capability comes from `Ember.ArrayProxy`, which this class inherits from. + + Sometimes you want to display computed properties within the body of an + `#each` helper that depend on the underlying items in `content`, but are not + present on those items. To do this, set `itemController` to the name of a + controller (probably an `ObjectController`) that will wrap each individual item. + + For example: + + ```handlebars + {{#each post in controller}} +
  • {{title}} ({{titleLength}} characters)
    • + {{/each}} + ``` + + ```javascript + App.PostsController = Ember.ArrayController.extend({ + itemController: 'post' + }); + + App.PostController = Ember.ObjectController.extend({ + // the `title` property will be proxied to the underlying post. + + titleLength: function() { + return this.get('title').length; + }.property('title') + }); + ``` + + In some cases it is helpful to return a different `itemController` depending + on the particular item. Subclasses can do this by overriding + `lookupItemController`. + + For example: + + ```javascript + App.MyArrayController = Ember.ArrayController.extend({ + lookupItemController: function( object ) { + if (object.get('isSpecial')) { + return "special"; // use App.SpecialController + } else { + return "regular"; // use App.RegularController + } + } + }); + ``` + + The itemController instances will have a `parentController` property set to + either the the `parentController` property of the `ArrayController` + or to the `ArrayController` instance itself. + + @class ArrayController + @namespace Ember + @extends Ember.ArrayProxy + @uses Ember.SortableMixin + @uses Ember.ControllerMixin +*/ + +Ember.ArrayController = Ember.ArrayProxy.extend(Ember.ControllerMixin, + Ember.SortableMixin, { + + /** + The controller used to wrap items, if any. + + @property itemController + @type String + @default null + */ + itemController: null, + + /** + Return the name of the controller to wrap items, or `null` if items should + be returned directly.

See + [Ember.Object](/api/classes/Ember.Object.html) documentation for more + information about concatenated properties. + + ## HTML Attributes + + The HTML attribute section of a view's tag can be set by providing an + `attributeBindings` property set to an array of property names on the view. + The return value of these properties will be used as the value of the view's + HTML associated attribute: + + ```javascript + AnchorView = Ember.View.extend({ + tagName: 'a', + attributeBindings: ['href'], + href: 'http://google.com' + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html + + ``` + + If the return value of an `attributeBindings` monitored property is a boolean + the property will follow HTML's pattern of repeating the attribute's name as + its value: + + ```javascript + MyTextInput = Ember.View.extend({ + tagName: 'input', + attributeBindings: ['disabled'], + disabled: true + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html + + ``` + + `attributeBindings` can refer to computed properties: + + ```javascript + MyTextInput = Ember.View.extend({ + tagName: 'input', + attributeBindings: ['disabled'], + disabled: function() { + if (someLogic) { + return true; + } else { + return false; + } + }.property() + }); + ``` + + Updates to the the property of an attribute binding will result in automatic + update of the HTML attribute in the view's rendered HTML representation. + + `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html) + documentation for more information about concatenated properties. + + ## Templates + + The HTML contents of a view's rendered representation are determined by its + template. Templates can be any function that accepts an optional context + parameter and returns a string of HTML that will be inserted within the + view's tag. Most typically in Ember this function will be a compiled + `Ember.Handlebars` template. + + ```javascript + AView = Ember.View.extend({ + template: Ember.Handlebars.compile('I am the template') + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    I am the template
    + ``` + + Within an Ember application is more common to define a Handlebars templates as + part of a page: + + ```html + + ``` + + And associate it by name using a view's `templateName` property: + + ```javascript + AView = Ember.View.extend({ + templateName: 'some-template' + }); + ``` + + Using a value for `templateName` that does not have a Handlebars template + with a matching `data-template-name` attribute will throw an error. + + For views classes that may have a template later defined (e.g. as the block + portion of a `{{view}}` Handlebars helper call in another template or in + a subclass), you can provide a `defaultTemplate` property set to compiled + template function. If a template is not later provided for the view instance + the `defaultTemplate` value will be used: + + ```javascript + AView = Ember.View.extend({ + defaultTemplate: Ember.Handlebars.compile('I was the default'), + template: null, + templateName: null + }); + ``` + + Will result in instances with an HTML representation of: + + ```html +
    I was the default
    + ``` + + If a `template` or `templateName` is provided it will take precedence over + `defaultTemplate`: + + ```javascript + AView = Ember.View.extend({ + defaultTemplate: Ember.Handlebars.compile('I was the default') + }); + + aView = AView.create({ + template: Ember.Handlebars.compile('I was the template, not default') + }); + ``` + + Will result in the following HTML representation when rendered: + + ```html +
    I was the template, not default
    + ``` + + ## View Context + + The default context of the compiled template is the view's controller: + + ```javascript + AView = Ember.View.extend({ + template: Ember.Handlebars.compile('Hello {{excitedGreeting}}') + }); + + aController = Ember.Object.create({ + firstName: 'Barry', + excitedGreeting: function() { + return this.get("content.firstName") + "!!!" + }.property() + }); + + aView = AView.create({ + controller: aController, + }); + ``` + + Will result in an HTML representation of: + + ```html +
    Hello Barry!!!
    + ``` + + A context can also be explicitly supplied through the view's `context` + property. If the view has neither `context` nor `controller` properties, the + `parentView`'s context will be used. + + ## Layouts + + Views can have a secondary template that wraps their main template. Like + primary templates, layouts can be any function that accepts an optional + context parameter and returns a string of HTML that will be inserted inside + view's tag. Views whose HTML element is self closing (e.g. ``) + cannot have a layout and this property will be ignored. + + Most typically in Ember a layout will be a compiled `Ember.Handlebars` + template. + + A view's layout can be set directly with the `layout` property or reference + an existing Handlebars template by name with the `layoutName` property. + + A template used as a layout must contain a single use of the Handlebars + `{{yield}}` helper. The HTML contents of a view's rendered `template` will be + inserted at this location: + + ```javascript + AViewWithLayout = Ember.View.extend({ + layout: Ember.Handlebars.compile("
    {{yield}}
    ") + template: Ember.Handlebars.compile("I got wrapped"), + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    +
    + I got wrapped +
    +
    + ``` + + See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield) + for more information. + + ## Responding to Browser Events + + Views can respond to user-initiated events in one of three ways: method + implementation, through an event manager, and through `{{action}}` helper use + in their template or layout. + + ### Method Implementation + + Views can respond to user-initiated events by implementing a method that + matches the event name. A `jQuery.Event` object will be passed as the + argument to this method. + + ```javascript + AView = Ember.View.extend({ + click: function(event) { + // will be called when when an instance's + // rendered element is clicked + } + }); + ``` + + ### Event Managers + + Views can define an object as their `eventManager` property. This object can + then implement methods that match the desired event names. Matching events + that occur on the view's rendered HTML or the rendered HTML of any of its DOM + descendants will trigger this method. A `jQuery.Event` object will be passed + as the first argument to the method and an `Ember.View` object as the + second. The `Ember.View` will be the view whose rendered HTML was interacted + with. This may be the view with the `eventManager` property or one of its + descendent views. + + ```javascript + AView = Ember.View.extend({ + eventManager: Ember.Object.create({ + doubleClick: function(event, view) { + // will be called when when an instance's + // rendered element or any rendering + // of this views's descendent + // elements is clicked + } + }) + }); + ``` + + An event defined for an event manager takes precedence over events of the + same name handled through methods on the view. + + ```javascript + AView = Ember.View.extend({ + mouseEnter: function(event) { + // will never trigger. + }, + eventManager: Ember.Object.create({ + mouseEnter: function(event, view) { + // takes precedence over AView#mouseEnter + } + }) + }); + ``` + + Similarly a view's event manager will take precedence for events of any views + rendered as a descendent. A method name that matches an event name will not + be called if the view instance was rendered inside the HTML representation of + a view that has an `eventManager` property defined that handles events of the + name. Events not handled by the event manager will still trigger method calls + on the descendent. + + ```javascript + OuterView = Ember.View.extend({ + template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"), + eventManager: Ember.Object.create({ + mouseEnter: function(event, view) { + // view might be instance of either + // OuterView or InnerView depending on + // where on the page the user interaction occured + } + }) + }); + + InnerView = Ember.View.extend({ + click: function(event) { + // will be called if rendered inside + // an OuterView because OuterView's + // eventManager doesn't handle click events + }, + mouseEnter: function(event) { + // will never be called if rendered inside + // an OuterView. + } + }); + ``` + + ### Handlebars `{{action}}` Helper + + See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action). + + ### Event Names + + All of the event handling approaches described above respond to the same set + of events. The names of the built-in events are listed below. (The hash of + built-in events exists in `Ember.EventDispatcher`.) Additional, custom events + can be registered by using `Ember.Application.customEvents`. + + Touch events: + + * `touchStart` + * `touchMove` + * `touchEnd` + * `touchCancel` + + Keyboard events + + * `keyDown` + * `keyUp` + * `keyPress` + + Mouse events + + * `mouseDown` + * `mouseUp` + * `contextMenu` + * `click` + * `doubleClick` + * `mouseMove` + * `focusIn` + * `focusOut` + * `mouseEnter` + * `mouseLeave` + + Form events: + + * `submit` + * `change` + * `focusIn` + * `focusOut` + * `input` + + HTML5 drag and drop events: + + * `dragStart` + * `drag` + * `dragEnter` + * `dragLeave` + * `drop` + * `dragEnd` + + ## Handlebars `{{view}}` Helper + + Other `Ember.View` instances can be included as part of a view's template by + using the `{{view}}` Handlebars helper.

    +
    Greetings Dave

    Greetings Mary
    +
    Greetings Sara
    +
    + ``` + + ### Specifying a CollectionView subclass + + By default the `{{collection}}` helper will create an instance of + `Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to + the helper by passing it as the first argument: + + ```handlebars + {{#collection App.MyCustomCollectionClass contentBinding="App.items"}} + Hi {{view.content.name}} + {{/collection}} + ``` + + ### Forwarded `item.*`-named Options + + As with the `{{view}}`, helper options passed to the `{{collection}}` will be + set on the resulting `Ember.CollectionView` as properties. Additionally, + options prefixed with `item` will be applied to the views rendered for each + item (note the camelcasing): + + ```handlebars + {{#collection contentBinding="App.items" + itemTagName="p" + itemClassNames="greeting"}} + Howdy {{view.content.name}} + {{/collection}} + ``` + + Will result in the following HTML structure: + + ```html +

    +
    Greetings Dave
    +
    Greetings Mary
    +
    Greetings Sara
    +
    + ``` + + If an `itemViewClass` is defined on the helper, and therefore the helper is not + being used as a block, an `emptyViewClass` can also be provided optionally. + The `emptyViewClass` will match the behavior of the `{{else}}` condition + described above. That is, the `emptyViewClass` will render if the collection + is empty. + + ### Representing each item with a Controller. + By default the controller lookup within an `{{#each}}` block will be + the controller of the template where the `{{#each}}` was used. If each + item needs to be presented by a custom controller you can provide a + `itemController` option which references a controller by lookup name. + Each item in the loop will be wrapped in an instance of this controller + and the item itself will be set to the `content` property of that controller. + + This is useful in cases where properties of model objects need transformation + or synthesis for display: + + ```javascript + App.DeveloperController = Ember.ObjectController.extend({ + isAvailableForHire: function() { + return !this.get('content.isEmployed') && this.get('content.isSeekingWork'); + }.property('isEmployed', 'isSeekingWork') + }) + ``` + + ```handlebars + {{#each person in developers itemController="developer"}} + {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}} + {{/each}} + ``` + + Each itemController will receive a reference to the current controller as + a `parentController` property. + + ### (Experimental) Grouped Each + + When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper), + you can inform Handlebars to re-render an entire group of items instead of + re-rendering them one at a time (in the event that they are changed en masse + or an item is added/removed). + + ```handlebars + {{#group}} + {{#each people}} + {{firstName}} {{lastName}} + {{/each}} + {{/group}} + ``` + + This can be faster than the normal way that Handlebars re-renders items + in some cases. + + If for some reason you have a group with more than one `#each`, you can make + one of the collections be updated in normal (non-grouped) fashion by setting + the option `groupedRows=true` (counter-intuitive, I know). + + For example, + + ```handlebars + {{dealershipName}} + + {{#group}} + {{#each dealers}} + {{firstName}} {{lastName}} + {{/each}} + + {{#each car in cars groupedRows=true}} + {{car.make}} {{car.model}} {{car.color}} + {{/each}} + {{/group}} + ``` + Any change to `dealershipName` or the `dealers` collection will cause the + entire group to be re-rendered.

See [Ember.View](/api/classes/Ember.View.html) + 'Responding to Browser Events' for more information. + + ### Specifying DOM event type + + By default the `{{action}}` helper registers for DOM `click` events. You can + supply an `on` option to the helper to specify a different DOM event name: + + ```handlebars +
    + click me +
    + ``` + + See `Ember.View` 'Responding to Browser Events' for a list of + acceptable DOM event names. + + NOTE: Because `{{action}}` depends on Ember's event dispatch system it will + only function if an `Ember.EventDispatcher` instance is available. An + `Ember.EventDispatcher` instance will be created when a new `Ember.Application` + is created. Having an instance of `Ember.Application` will satisfy this + requirement. + + ### Specifying whitelisted modifier keys + + By default the `{{action}}` helper will ignore click event with pressed modifier + keys. You can supply an `allowedKeys` option to specify which keys should not be ignored. + + ```handlebars +
    + click me +
    + ``` + + This way the `{{action}}` will fire when clicking with the alt key pressed down. + + Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys. + + ```handlebars +
    + click me with any key pressed +
    + ``` + + ### Specifying a Target + + There are several possible target objects for `{{action}}` helpers: + + In a typical Ember application, where views are managed through use of the + `{{outlet}}` helper, actions will bubble to the current controller, then + to the current route, and then up the route hierarchy. + + Alternatively, a `target` option can be provided to the helper to change + which object will receive the method call. This option must be a path + to an object, accessible in the current context: + + ```handlebars + {{! the application template }} +
    + click me +
    + ``` + + ```javascript + App.ApplicationView = Ember.View.extend({ + actions: { + anActionName: function(){} + } + }); + + ``` + + ### Additional Parameters + + You may specify additional parameters to the `{{action}}` helper.

    + click me +

It helps to instantiate, initialize and coordinate the many + objects that make up your app. + + Each Ember app has one and only one `Ember.Application` object. In fact, the + very first thing you should do in your application is create the instance: + + ```javascript + window.App = Ember.Application.create(); + ``` + + Typically, the application object is the only global variable. All other + classes in your app should be properties on the `Ember.Application` instance, + which highlights its first role: a global namespace. + + For example, if you define a view class, it might look like this: + + ```javascript + App.MyView = Ember.View.extend(); + ``` + + By default, calling `Ember.Application.create()` will automatically initialize + your application by calling the `Ember.Application.initialize()` method. If + you need to delay initialization, you can call your app's `deferReadiness()` + method. When you are ready for your app to be initialized, call its + `advanceReadiness()` method. + + You can define a `ready` method on the `Ember.Application` instance, which + will be run by Ember when the application is initialized. + + Because `Ember.Application` inherits from `Ember.Namespace`, any classes + you create will have useful string representations when calling `toString()`. + See the `Ember.Namespace` documentation for more information. + + While you can think of your `Ember.Application` as a container that holds the + other classes in your application, there are several other responsibilities + going on under-the-hood that you may want to understand. + + ### Event Delegation + + Ember uses a technique called _event delegation_. This allows the framework + to set up a global, shared event listener instead of requiring each view to + do it manually. For example, instead of each view registering its own + `mousedown` listener on its associated element, Ember sets up a `mousedown` + listener on the `body`. + + If a `mousedown` event occurs, Ember will look at the target of the event and + start walking up the DOM node tree, finding corresponding views and invoking + their `mouseDown` method as it goes. + + `Ember.Application` has a number of default events that it listens for, as + well as a mapping from lowercase events to camel-cased view method names. For + example, the `keypress` event causes the `keyPress` method on the view to be + called, the `dblclick` event causes `doubleClick` to be called, and so on. + + If there is a bubbling browser event that Ember does not listen for by + default, you can specify custom events and their corresponding view method + names by setting the application's `customEvents` property: + + ```javascript + App = Ember.Application.create({ + customEvents: { + // add support for the paste event + 'paste: "paste" + } + }); + ``` + + By default, the application sets up these event listeners on the document + body. However, in cases where you are embedding an Ember application inside + an existing page, you may want it to set up the listeners on an element + inside the body. + + For example, if only events inside a DOM element with the ID of `ember-app` + should be delegated, set your application's `rootElement` property: + + ```javascript + window.App = Ember.Application.create({ + rootElement: '#ember-app' + }); + ``` + + The `rootElement` can be either a DOM element or a jQuery-compatible selector + string. Note that *views appended to the DOM outside the root element will + not receive events.* If you specify a custom root element, make sure you only + append views inside it! + + To learn more about the advantages of event delegation and the Ember view + layer, and a list of the event listeners that are setup by default, visit the + [Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation). + + ### Initializers + + Libraries on top of Ember can register additional initializers, like so: + + ```javascript + Ember.Application.initializer({ + name: "store", + + initialize: function(container, application) { + container.register('store:main', application.Store); + } + }); + ``` + + ### Routing + + In addition to creating your application's router, `Ember.Application` is + also responsible for telling the router when to start routing. Transitions + between routes can be logged with the `LOG_TRANSITIONS` flag, and more + detailed intra-transition logging can be logged with + the `LOG_TRANSITIONS_INTERNAL` flag: + + ```javascript + window.App = Ember.Application.create({ + LOG_TRANSITIONS: true, // basic logging of successful transitions + LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps + }); + ``` + + By default, the router will begin trying to translate the current URL into + application state once the browser emits the `DOMContentReady` event. If you + need to defer routing, you can call the application's `deferReadiness()` + method. Once routing can begin, call the `advanceReadiness()` method. + + If there is any setup required before routing begins, you can implement a + `ready()` method on your app that will be invoked immediately before routing + begins. + ``` + + @class Application + @namespace Ember + @extends Ember.Namespace +*/ + +var Application = Ember.Application = Ember.Namespace.extend(Ember.DeferredMixin, { + + /** + The root DOM element of the Application.

    + ``` + + `class` attribute values can also be set by providing a `classNameBindings` + property set to an array of properties names for the view. The return value + of these properties will be added as part of the value for the view's `class` + attribute. These properties can be computed properties: + + ```javascript + MyView = Ember.View.extend({ + classNameBindings: ['propertyA', 'propertyB'], + propertyA: 'from-a', + propertyB: function() { + if (someLogic) { return 'from-b'; } + }.property() + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    + ``` + + If the value of a class name binding returns a boolean the property name + itself will be used as the class name if the property is true.

    + ``` + + When using boolean class name bindings you can supply a string value other + than the property name for use as the `class` HTML attribute by appending the + preferred value after a ":" character when defining the binding: + + ```javascript + MyView = Ember.View.extend({ + classNameBindings: ['awesome:so-very-cool'], + awesome: true + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +

    + ``` + + When the `isEnabled` property on the view is set to `false`, it will result + in view instances with an HTML representation of: + + ```html +
    + ``` + + Updates to the the value of a class name binding will result in automatic + update of the HTML `class` attribute in the view's rendered HTML + representation.

See + [Ember.Object](/api/classes/Ember.Object.html) documentation for more + information about concatenated properties. + + ## HTML Attributes + + The HTML attribute section of a view's tag can be set by providing an + `attributeBindings` property set to an array of property names on the view. + The return value of these properties will be used as the value of the view's + HTML associated attribute: + + ```javascript + AnchorView = Ember.View.extend({ + tagName: 'a', + attributeBindings: ['href'], + href: 'http://google.com' + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html + + ``` + + If the return value of an `attributeBindings` monitored property is a boolean + the property will follow HTML's pattern of repeating the attribute's name as + its value: + + ```javascript + MyTextInput = Ember.View.extend({ + tagName: 'input', + attributeBindings: ['disabled'], + disabled: true + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html + + ``` + + `attributeBindings` can refer to computed properties: + + ```javascript + MyTextInput = Ember.View.extend({ + tagName: 'input', + attributeBindings: ['disabled'], + disabled: function() { + if (someLogic) { + return true; + } else { + return false; + } + }.property() + }); + ``` + + Updates to the the property of an attribute binding will result in automatic + update of the HTML attribute in the view's rendered HTML representation. + + `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html) + documentation for more information about concatenated properties. + + ## Templates + + The HTML contents of a view's rendered representation are determined by its + template. Templates can be any function that accepts an optional context + parameter and returns a string of HTML that will be inserted within the + view's tag. Most typically in Ember this function will be a compiled + `Ember.Handlebars` template. + + ```javascript + AView = Ember.View.extend({ + template: Ember.Handlebars.compile('I am the template') + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    I am the template
    + ``` + + Within an Ember application is more common to define a Handlebars templates as + part of a page: + + ```html + + ``` + + And associate it by name using a view's `templateName` property: + + ```javascript + AView = Ember.View.extend({ + templateName: 'some-template' + }); + ``` + + Using a value for `templateName` that does not have a Handlebars template + with a matching `data-template-name` attribute will throw an error. + + For views classes that may have a template later defined (e.g. as the block + portion of a `{{view}}` Handlebars helper call in another template or in + a subclass), you can provide a `defaultTemplate` property set to compiled + template function. If a template is not later provided for the view instance + the `defaultTemplate` value will be used: + + ```javascript + AView = Ember.View.extend({ + defaultTemplate: Ember.Handlebars.compile('I was the default'), + template: null, + templateName: null + }); + ``` + + Will result in instances with an HTML representation of: + + ```html +
    I was the default
    + ``` + + If a `template` or `templateName` is provided it will take precedence over + `defaultTemplate`: + + ```javascript + AView = Ember.View.extend({ + defaultTemplate: Ember.Handlebars.compile('I was the default') + }); + + aView = AView.create({ + template: Ember.Handlebars.compile('I was the template, not default') + }); + ``` + + Will result in the following HTML representation when rendered: + + ```html +
    I was the template, not default
    + ``` + + ## View Context + + The default context of the compiled template is the view's controller: + + ```javascript + AView = Ember.View.extend({ + template: Ember.Handlebars.compile('Hello {{excitedGreeting}}') + }); + + aController = Ember.Object.create({ + firstName: 'Barry', + excitedGreeting: function() { + return this.get("content.firstName") + "!!!" + }.property() + }); + + aView = AView.create({ + controller: aController, + }); + ``` + + Will result in an HTML representation of: + + ```html +
    Hello Barry!!!
    + ``` + + A context can also be explicitly supplied through the view's `context` + property. If the view has neither `context` nor `controller` properties, the + `parentView`'s context will be used. + + ## Layouts + + Views can have a secondary template that wraps their main template. Like + primary templates, layouts can be any function that accepts an optional + context parameter and returns a string of HTML that will be inserted inside + view's tag. Views whose HTML element is self closing (e.g. ``) + cannot have a layout and this property will be ignored. + + Most typically in Ember a layout will be a compiled `Ember.Handlebars` + template. + + A view's layout can be set directly with the `layout` property or reference + an existing Handlebars template by name with the `layoutName` property. + + A template used as a layout must contain a single use of the Handlebars + `{{yield}}` helper. The HTML contents of a view's rendered `template` will be + inserted at this location: + + ```javascript + AViewWithLayout = Ember.View.extend({ + layout: Ember.Handlebars.compile("
    {{yield}}
    ") + template: Ember.Handlebars.compile("I got wrapped"), + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    +
    + I got wrapped +
    +
    + ``` + + See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield) + for more information. + + ## Responding to Browser Events + + Views can respond to user-initiated events in one of three ways: method + implementation, through an event manager, and through `{{action}}` helper use + in their template or layout. + + ### Method Implementation + + Views can respond to user-initiated events by implementing a method that + matches the event name. A `jQuery.Event` object will be passed as the + argument to this method. + + ```javascript + AView = Ember.View.extend({ + click: function(event) { + // will be called when when an instance's + // rendered element is clicked + } + }); + ``` + + ### Event Managers + + Views can define an object as their `eventManager` property. This object can + then implement methods that match the desired event names. Matching events + that occur on the view's rendered HTML or the rendered HTML of any of its DOM + descendants will trigger this method. A `jQuery.Event` object will be passed + as the first argument to the method and an `Ember.View` object as the + second. The `Ember.View` will be the view whose rendered HTML was interacted + with. This may be the view with the `eventManager` property or one of its + descendent views. + + ```javascript + AView = Ember.View.extend({ + eventManager: Ember.Object.create({ + doubleClick: function(event, view) { + // will be called when when an instance's + // rendered element or any rendering + // of this views's descendent + // elements is clicked + } + }) + }); + ``` + + An event defined for an event manager takes precedence over events of the + same name handled through methods on the view. + + ```javascript + AView = Ember.View.extend({ + mouseEnter: function(event) { + // will never trigger. + }, + eventManager: Ember.Object.create({ + mouseEnter: function(event, view) { + // takes precedence over AView#mouseEnter + } + }) + }); + ``` + + Similarly a view's event manager will take precedence for events of any views + rendered as a descendent. A method name that matches an event name will not + be called if the view instance was rendered inside the HTML representation of + a view that has an `eventManager` property defined that handles events of the + name. Events not handled by the event manager will still trigger method calls + on the descendent. + + ```javascript + OuterView = Ember.View.extend({ + template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"), + eventManager: Ember.Object.create({ + mouseEnter: function(event, view) { + // view might be instance of either + // OuterView or InnerView depending on + // where on the page the user interaction occured + } + }) + }); + + InnerView = Ember.View.extend({ + click: function(event) { + // will be called if rendered inside + // an OuterView because OuterView's + // eventManager doesn't handle click events + }, + mouseEnter: function(event) { + // will never be called if rendered inside + // an OuterView. + } + }); + ``` + + ### Handlebars `{{action}}` Helper + + See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action). + + ### Event Names + + All of the event handling approaches described above respond to the same set + of events. The names of the built-in events are listed below. (The hash of + built-in events exists in `Ember.EventDispatcher`.) Additional, custom events + can be registered by using `Ember.Application.customEvents`. + + Touch events: + + * `touchStart` + * `touchMove` + * `touchEnd` + * `touchCancel` + + Keyboard events + + * `keyDown` + * `keyUp` + * `keyPress` + + Mouse events + + * `mouseDown` + * `mouseUp` + * `contextMenu` + * `click` + * `doubleClick` + * `mouseMove` + * `focusIn` + * `focusOut` + * `mouseEnter` + * `mouseLeave` + + Form events: + + * `submit` + * `change` + * `focusIn` + * `focusOut` + * `input` + + HTML5 drag and drop events: + + * `dragStart` + * `drag` + * `dragEnter` + * `dragLeave` + * `drop` + * `dragEnd` + + ## Handlebars `{{view}}` Helper + + Other `Ember.View` instances can be included as part of a view's template by + using the `{{view}}` Handlebars helper.

If you name a template + `components/my-foo`, you will be able to use + `{{my-foo}}` in other templates, which will make + an instance of the isolated component. + + ```html + {{app-profile person=currentUser}} + ``` + + ```html + +

    {{person.title}}

    + +

    {{person.signature}}

    + ``` + + You can also use `yield` inside a template to + include the **contents** of the custom tag: + + ```html + {{#app-profile person=currentUser}} +

    Admin mode

    + {{/app-profile}} + ``` + + ```html + +

    {{person.title}}

    + {{yield}} + ``` + + If you want to customize the component, in order to + handle events or actions, you implement a subclass + of `Ember.Component` named after the name of the + component. Note that `Component` needs to be appended to the name of + your subclass like `AppProfileComponent`. + + For example, you could implement the action + `hello` for the `app-profile` component: + + ```javascript + App.AppProfileComponent = Ember.Component.extend({ + actions: { + hello: function(name) { + console.log("Hello", name); + } + } + }); + ``` + + And then use it in the component's template: + + ```html + + +

    {{person.title}}

    + {{yield}} + + + ``` + + Components must have a `-` in their name to avoid + conflicts with built-in controls that wrap HTML + elements.

Attempts to use both a `templateName` option and supply a + block will throw an error. + + ```handlebars + {{view "MyApp.ViewWithATemplateDefined"}} + ``` + + ### `viewName` property + + You can supply a `viewName` option to `{{view}}`.

    +
    Greetings Dave
    +
    Greetings Mary
    +
    Greetings Sara
    +
    + ``` + + ### Specifying a CollectionView subclass + + By default the `{{collection}}` helper will create an instance of + `Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to + the helper by passing it as the first argument: + + ```handlebars + {{#collection App.MyCustomCollectionClass contentBinding="App.items"}} + Hi {{view.content.name}} + {{/collection}} + ``` + + ### Forwarded `item.*`-named Options + + As with the `{{view}}`, helper options passed to the `{{collection}}` will be + set on the resulting `Ember.CollectionView` as properties. Additionally, + options prefixed with `item` will be applied to the views rendered for each + item (note the camelcasing): + + ```handlebars + {{#collection contentBinding="App.items" + itemTagName="p" + itemClassNames="greeting"}} + Howdy {{view.content.name}} + {{/collection}} + ``` + + Will result in the following HTML structure: + + ```html +

    +
    Greetings Dave
    +
    Greetings Mary
    +
    Greetings Sara
    +
    + ``` + + If an `itemViewClass` is defined on the helper, and therefore the helper is not + being used as a block, an `emptyViewClass` can also be provided optionally. + The `emptyViewClass` will match the behavior of the `{{else}}` condition + described above. That is, the `emptyViewClass` will render if the collection + is empty. + + ### Representing each item with a Controller. + By default the controller lookup within an `{{#each}}` block will be + the controller of the template where the `{{#each}}` was used. If each + item needs to be presented by a custom controller you can provide a + `itemController` option which references a controller by lookup name. + Each item in the loop will be wrapped in an instance of this controller + and the item itself will be set to the `content` property of that controller. + + This is useful in cases where properties of model objects need transformation + or synthesis for display: + + ```javascript + App.DeveloperController = Ember.ObjectController.extend({ + isAvailableForHire: function() { + return !this.get('content.isEmployed') && this.get('content.isSeekingWork'); + }.property('isEmployed', 'isSeekingWork') + }) + ``` + + ```handlebars + {{#each person in developers itemController="developer"}} + {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}} + {{/each}} + ``` + + Each itemController will receive a reference to the current controller as + a `parentController` property. + + ### (Experimental) Grouped Each + + When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper), + you can inform Handlebars to re-render an entire group of items instead of + re-rendering them one at a time (in the event that they are changed en masse + or an item is added/removed). + + ```handlebars + {{#group}} + {{#each people}} + {{firstName}} {{lastName}} + {{/each}} + {{/group}} + ``` + + This can be faster than the normal way that Handlebars re-renders items + in some cases. + + If for some reason you have a group with more than one `#each`, you can make + one of the collections be updated in normal (non-grouped) fashion by setting + the option `groupedRows=true` (counter-intuitive, I know). + + For example, + + ```handlebars + {{dealershipName}} + + {{#group}} + {{#each dealers}} + {{firstName}} {{lastName}} + {{/each}} + + {{#each car in cars groupedRows=true}} + {{car.make}} {{car.model}} {{car.color}} + {{/each}} + {{/group}} + ``` + Any change to `dealershipName` or the `dealers` collection will cause the + entire group to be re-rendered. However, changes to the `cars` collection + will be re-rendered individually (as normal). + + Note that `group` behavior is also disabled by specifying an `itemViewClass`. + + @method each + @for Ember.Handlebars.helpers + @param [name] {String} name for item (used with `in`) + @param [path] {String} path + @param [options] {Object} Handlebars key/value pairs of options + @param [options.itemViewClass] {String} a path to a view class used for each item + @param [options.itemController] {String} name of a controller to be created for each item + @param [options.groupedRows] {boolean} enable normal item-by-item rendering when inside a `#group` helper +*/ +Ember.Handlebars.registerHelper('each', function(path, options) { + if (arguments.length === 4) { + + + var keywordName = arguments[0]; + + options = arguments[3]; + path = arguments[2]; + if (path === '') { path = "this"; } + + options.hash.keyword = keywordName; + } + + if (arguments.length === 1) { + options = path; + path = 'this'; + } + + options.hash.dataSourceBinding = path; + // Set up emptyView as a metamorph with no tag + //options.hash.emptyViewClass = Ember._MetamorphView; + + if (options.data.insideGroup && !options.hash.groupedRows && !options.hash.itemViewClass) { + new Ember.Handlebars.GroupedEach(this, path, options).render(); + } else { + return Ember.Handlebars.helpers.collection.call(this, 'Ember.Handlebars.EachView', options); + } +}); + +})(); + + + +(function() { +/** +@module ember +@submodule ember-handlebars +*/ + +/** + `template` allows you to render a template from inside another template. + This allows you to re-use the same template in multiple places.

  • + Great Hamster Photos +
    • + ``` + + To override this option for your entire application, see + "Overriding Application-wide Defaults". + + ### Disabling the `link-to` helper + By default `{{link-to}}` is enabled. + any passed value to `disabled` helper property will disable the `link-to` helper. + + static use: the `disabled` option: + + ```handlebars + {{#link-to 'photoGallery' disabled=true}} + Great Hamster Photos + {{/link-to}} + ``` + + dynamic use: the `disabledWhen` option: + + ```handlebars + {{#link-to 'photoGallery' disabledWhen=controller.someProperty}} + Great Hamster Photos + {{/link-to}} + ``` + + any passed value to `disabled` will disable it except `undefined`. + to ensure that only `true` disable the `link-to` helper you can + override the global behaviour of `Ember.LinkView`. + + ```javascript + Ember.LinkView.reopen({ + disabled: Ember.computed(function(key, value) { + if (value !== undefined) { + this.set('_isDisabled', value === true); + } + return value === true ? get(this, 'disabledClass') : false; + }) + }); + ``` + + see "Overriding Application-wide Defaults" for more. + + ### Handling `href` + `{{link-to}}` will use your application's Router to + fill the element's `href` property with a url that + matches the path to the supplied `routeName` for your + routers's configured `Location` scheme, which defaults + to Ember.HashLocation. + + ### Handling current route + `{{link-to}}` will apply a CSS class name of 'active' + when the application's current route matches + the supplied routeName.

This argument will become the value + of the dynamic segment: + + ```javascript + App.Router.map(function() { + this.resource("photoGallery", {path: "hamster-photos/:photo_id"}); + }); + ``` + + ```handlebars + {{#link-to 'photoGallery' aPhotoId}} + {{aPhoto.title}} + {{/link-to}} + ``` + + ```html + + Tomster + + ``` + + When transitioning into the linked route, the `model` hook will + be triggered with parameters including this passed identifier. + + ### Overriding attributes + You can override any given property of the Ember.LinkView + that is generated by the `{{link-to}}` helper by passing + key/value pairs, like so: + + ```handlebars + {{#link-to aPhoto tagName='li' title='Following this link will change your life' classNames=['pic', 'sweet']}} + Uh-mazing! + {{/link-to}} + ``` + + See [Ember.LinkView](/api/classes/Ember.LinkView.html) for a + complete list of overrideable properties.

    + click me +
    + ``` + + See `Ember.View` 'Responding to Browser Events' for a list of + acceptable DOM event names. + + NOTE: Because `{{action}}` depends on Ember's event dispatch system it will + only function if an `Ember.EventDispatcher` instance is available. An + `Ember.EventDispatcher` instance will be created when a new `Ember.Application` + is created. Having an instance of `Ember.Application` will satisfy this + requirement. + + ### Specifying whitelisted modifier keys + + By default the `{{action}}` helper will ignore click event with pressed modifier + keys. You can supply an `allowedKeys` option to specify which keys should not be ignored. + + ```handlebars +
    + click me +
    + ``` + + This way the `{{action}}` will fire when clicking with the alt key pressed down. + + Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys. + + ```handlebars +
    + click me with any key pressed +
    + ``` + + ### Specifying a Target + + There are several possible target objects for `{{action}}` helpers: + + In a typical Ember application, where views are managed through use of the + `{{outlet}}` helper, actions will bubble to the current controller, then + to the current route, and then up the route hierarchy. + + Alternatively, a `target` option can be provided to the helper to change + which object will receive the method call.

    + click me +
    + ``` + + ```javascript + App.ApplicationView = Ember.View.extend({ + actions: { + anActionName: function(){} + } + }); + + ``` + + ### Additional Parameters + + You may specify additional parameters to the `{{action}}` helper.

All other + classes in your app should be properties on the `Ember.Application` instance, + which highlights its first role: a global namespace. + + For example, if you define a view class, it might look like this: + + ```javascript + App.MyView = Ember.View.extend(); + ``` + + By default, calling `Ember.Application.create()` will automatically initialize + your application by calling the `Ember.Application.initialize()` method. If + you need to delay initialization, you can call your app's `deferReadiness()` + method. When you are ready for your app to be initialized, call its + `advanceReadiness()` method. + + You can define a `ready` method on the `Ember.Application` instance, which + will be run by Ember when the application is initialized. + + Because `Ember.Application` inherits from `Ember.Namespace`, any classes + you create will have useful string representations when calling `toString()`. + See the `Ember.Namespace` documentation for more information. + + While you can think of your `Ember.Application` as a container that holds the + other classes in your application, there are several other responsibilities + going on under-the-hood that you may want to understand. + + ### Event Delegation + + Ember uses a technique called _event delegation_. This allows the framework + to set up a global, shared event listener instead of requiring each view to + do it manually. For example, instead of each view registering its own + `mousedown` listener on its associated element, Ember sets up a `mousedown` + listener on the `body`. + + If a `mousedown` event occurs, Ember will look at the target of the event and + start walking up the DOM node tree, finding corresponding views and invoking + their `mouseDown` method as it goes. + + `Ember.Application` has a number of default events that it listens for, as + well as a mapping from lowercase events to camel-cased view method names. For + example, the `keypress` event causes the `keyPress` method on the view to be + called, the `dblclick` event causes `doubleClick` to be called, and so on. + + If there is a bubbling browser event that Ember does not listen for by + default, you can specify custom events and their corresponding view method + names by setting the application's `customEvents` property: + + ```javascript + App = Ember.Application.create({ + customEvents: { + // add support for the paste event + 'paste: "paste" + } + }); + ``` + + By default, the application sets up these event listeners on the document + body. However, in cases where you are embedding an Ember application inside + an existing page, you may want it to set up the listeners on an element + inside the body. + + For example, if only events inside a DOM element with the ID of `ember-app` + should be delegated, set your application's `rootElement` property: + + ```javascript + window.App = Ember.Application.create({ + rootElement: '#ember-app' + }); + ``` + + The `rootElement` can be either a DOM element or a jQuery-compatible selector + string. Note that *views appended to the DOM outside the root element will + not receive events.* If you specify a custom root element, make sure you only + append views inside it! + + To learn more about the advantages of event delegation and the Ember view + layer, and a list of the event listeners that are setup by default, visit the + [Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation). + + ### Initializers + + Libraries on top of Ember can register additional initializers, like so: + + ```javascript + Ember.Application.initializer({ + name: "store", + + initialize: function(container, application) { + container.register('store:main', application.Store); + } + }); + ``` + + ### Routing + + In addition to creating your application's router, `Ember.Application` is + also responsible for telling the router when to start routing. Transitions + between routes can be logged with the `LOG_TRANSITIONS` flag, and more + detailed intra-transition logging can be logged with + the `LOG_TRANSITIONS_INTERNAL` flag: + + ```javascript + window.App = Ember.Application.create({ + LOG_TRANSITIONS: true, // basic logging of successful transitions + LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps + }); + ``` + + By default, the router will begin trying to translate the current URL into + application state once the browser emits the `DOMContentReady` event. If you + need to defer routing, you can call the application's `deferReadiness()` + method. Once routing can begin, call the `advanceReadiness()` method. + + If there is any setup required before routing begins, you can implement a + `ready()` method on your app that will be invoked immediately before routing + begins. + ``` + + @class Application + @namespace Ember + @extends Ember.Namespace +*/ + +var Application = Ember.Application = Ember.Namespace.extend(Ember.DeferredMixin, { + + /** + The root DOM element of the Application.

This means that you can override +the CSS of styled components the same as any native element since your +app's CSS will be applied after. + +Contributing +------------ + +```sh +bower install +npm install +npm test +``` + +License and Copyright +--------------------- + +MIT Style license + +(c) 2013 Instructure, Inc. + diff --git a/public/javascripts/bower/ic-styled/bower.json b/public/javascripts/bower/ic-styled/bower.json new file mode 100644 index 00000000000..ded34ffa254 --- /dev/null +++ b/public/javascripts/bower/ic-styled/bower.json @@ -0,0 +1,25 @@ +{ + "name": "ic-styled", + "version": "1.1.3", + "authors": [ + "Ryan Florence " + ], + "main": "main.js", + "moduleFormat": [ + "amd", + "cjs", + "globals" + ], + "license": "MIT", + "ignore": [ + "bower_components", + "node_modules", + "package.json", + "testem.json", + "test.js", + "**/.*" + ], + "dependencies": { + "ember": "~1.2.0" + } +} \ No newline at end of file diff --git a/public/javascripts/bower/ic-styled/main.js b/public/javascripts/bower/ic-styled/main.js new file mode 100644 index 00000000000..f425f9c5448 --- /dev/null +++ b/public/javascripts/bower/ic-styled/main.js @@ -0,0 +1,54 @@ +/*! + * ic-styled + * please see license at https://github.com/instructure/ic-styled + */ + +;(function(root, factory) { + if (typeof define === 'function' && define.amd) { + define(['ember'], function(Ember) { return factory(Ember); }); + } else if (typeof exports === 'object') { + module.exports = factory(require('ember')); + } else { + root.ic = root.ic || {}; + root.ic.Styled = factory(Ember); + } +}(this, function(Ember) { + + /* + * Auto-injects a sister component containing the styles for this component. + * Given a component `x-foo` create a template at `components/x-foo-css`, + * treat it like a `css` file, it becomes a `
