Ember Data always uses the `id` property to store the id of - the record. The external source may not always follow this - convention.

If - you specify a transform, the JavaScript value will be - serialized when inserted into the JSON hash. - - By default, belongs-to relationships are converted into - IDs when inserted into the JSON hash. - - ## IDs - - `serialize` takes an options hash with a single option: - `includeId`. If this option is `true`, `serialize` will, - by default include the ID in the JSON object it builds. - - The adapter passes in `includeId: true` when serializing - a record for `createRecord`, but not for `updateRecord`. - - ## Customization - - Your server may expect a different JSON format than the - built-in serialization format. - - In that case, you can implement `serialize` yourself and - return a JSON hash of your choosing. - - ```javascript - App.PostSerializer = DS.JSONSerializer.extend({ - serialize: function(post, options) { - var json = { - POST_TTL: post.get('title'), - POST_BDY: post.get('body'), - POST_CMS: post.get('comments').mapProperty('id') - } - - if (options.includeId) { - json.POST_ID_ = post.get('id'); - } - - return json; - } - }); - ``` - - ## Customizing an App-Wide Serializer - - If you want to define a serializer for your entire - application, you'll probably want to use `eachAttribute` - and `eachRelationship` on the record. - - ```javascript - App.ApplicationSerializer = DS.JSONSerializer.extend({ - serialize: function(record, options) { - var json = {}; - - record.eachAttribute(function(name) { - json[serverAttributeName(name)] = record.get(name); - }) - - record.eachRelationship(function(name, relationship) { - if (relationship.kind === 'hasMany') { - json[serverHasManyName(name)] = record.get(name).mapBy('id'); - } - }); - - if (options.includeId) { - json.ID_ = record.get('id'); - } - - return json; - } - }); - - function serverAttributeName(attribute) { - return attribute.underscore().toUpperCase(); - } - - function serverHasManyName(name) { - return serverAttributeName(name.singularize()) + "_IDS"; - } - ``` - - This serializer will generate JSON that looks like this: - - ```javascript - { - "TITLE": "Rails is omakase", - "BODY": "Yep. Omakase.", - "COMMENT_IDS": [ 1, 2, 3 ] - } - ``` - - ## Tweaking the Default JSON - - If you just want to do some small tweaks on the default JSON, - you can call super first and make the tweaks on the returned - JSON. - - ```javascript - App.PostSerializer = DS.JSONSerializer.extend({ - serialize: function(record, options) { - var json = this._super.apply(this, arguments); - - json.subject = json.title; - delete json.title; - - return json; - } - }); - ``` - - @method serialize - @param {subclass of DS.Model} record - @param {Object} options - @return {Object} json - */ - serialize: function(record, options) { - var json = {}; - - if (options && options.includeId) { - var id = get(record, 'id'); - - if (id) { - json[get(this, 'primaryKey')] = id; - } - } - - record.eachAttribute(function(key, attribute) { - this.serializeAttribute(record, json, key, attribute); - }, this); - - record.eachRelationship(function(key, relationship) { - if (relationship.kind === 'belongsTo') { - this.serializeBelongsTo(record, json, relationship); - } else if (relationship.kind === 'hasMany') { - this.serializeHasMany(record, json, relationship); - } - }, this); - - return json; - }, - - /** - `serializeAttribute` can be used to customize how `DS.attr` - properties are serialized - - For example if you wanted to ensure all you attributes were always - serialized as properties on an `attributes` object you could - write: - - ```javascript - App.ApplicationSerializer = DS.JSONSerializer.extend({ - serializeAttribute: function(record, json, key, attributes) { - json.attributes = json.attributes || {}; - this._super(record, json.attributes, key, attributes); - } - }); - ``` - - @method serializeAttribute - @param {DS.Model} record - @param {Object} json - @param {String} key - @param {Object} attribute - */ - serializeAttribute: function(record, json, key, attribute) { - var attrs = get(this, 'attrs'); - var value = get(record, key), type = attribute.type; - - if (type) { - var transform = this.transformFor(type); - value = transform.serialize(value); - } - - // if provided, use the mapping provided by `attrs` in - // the serializer - key = attrs && attrs[key] || (this.keyForAttribute ? this.keyForAttribute(key) : key); - - json[key] = value; - }, - - /** - `serializeBelongsTo` can be used to customize how `DS.belongsTo` - properties are serialized. - - Example - - ```javascript - App.PostSerializer = DS.JSONSerializer.extend({ - serializeBelongsTo: function(record, json, relationship) { - var key = relationship.key; - - var belongsTo = get(record, key); - - key = this.keyForRelationship ? this.keyForRelationship(key, "belongsTo") : key; - - json[key] = Ember.isNone(belongsTo) ? belongsTo : belongsTo.toJSON(); - } - }); - ``` - - @method serializeBelongsTo - @param {DS.Model} record - @param {Object} json - @param {Object} relationship - */ - serializeBelongsTo: function(record, json, relationship) { - var key = relationship.key; - - var belongsTo = get(record, key); - - key = this.keyForRelationship ? this.keyForRelationship(key, "belongsTo") : key; - - if (isNone(belongsTo)) { - json[key] = belongsTo; - } else { - json[key] = get(belongsTo, 'id'); - } - - if (relationship.options.polymorphic) { - this.serializePolymorphicType(record, json, relationship); - } - }, - - /** - `serializeHasMany` can be used to customize how `DS.hasMany` - properties are serialized. - - Example - - ```javascript - App.PostSerializer = DS.JSONSerializer.extend({ - serializeHasMany: function(record, json, relationship) { - var key = relationship.key; - if (key === 'comments') { - return; - } else { - this._super.apply(this, arguments); - } - } - }); - ``` - - @method serializeHasMany - @param {DS.Model} record - @param {Object} json - @param {Object} relationship - */ - serializeHasMany: function(record, json, relationship) { - var key = relationship.key; - - var relationshipType = DS.RelationshipChange.determineRelationshipType(record.constructor, relationship); - - if (relationshipType === 'manyToNone' || relationshipType === 'manyToMany') { - json[key] = get(record, key).mapBy('id'); - // TODO support for polymorphic manyToNone and manyToMany relationships - } - }, - - /** - You can use this method to customize how polymorphic objects are - serialized.

What we mean is - that, the hierarchical states that each of *those* points to is a - shared data structure. For performance reasons, instead of each - record getting its own copy of the hierarchy of states, each record - points to this global, immutable shared instance. How does a state - know which record it should be acting on? We pass the record - instance into the state's event handlers as the first argument. - - The record passed as the first parameter is where you should stash - state about the record if needed; you should never store data on the state - object itself. - - ### Events and Flags - - A state may implement zero or more events and flags. - - #### Events - - Events are named functions that are invoked when sent to a record. The - record will first look for a method with the given name on the - current state. If no method is found, it will search the current - state's parent, and then its grandparent, and so on until reaching - the top of the hierarchy. If the root is reached without an event - handler being found, an exception will be raised. This can be very - helpful when debugging new features. - - Here's an example implementation of a state with a `myEvent` event handler: - - ```javascript - aState: DS.State.create({ - myEvent: function(manager, param) { - console.log("Received myEvent with", param); - } - }) - ``` - - To trigger this event: - - ```javascript - record.send('myEvent', 'foo'); - //=> "Received myEvent with foo" - ``` - - Note that an optional parameter can be sent to a record's `send()` method, - which will be passed as the second parameter to the event handler. - - Events should transition to a different state if appropriate. This can be - done by calling the record's `transitionTo()` method with a path to the - desired state. The state manager will attempt to resolve the state path - relative to the current state. If no state is found at that path, it will - attempt to resolve it relative to the current state's parent, and then its - parent, and so on until the root is reached. For example, imagine a hierarchy - like this: - - * created - * uncommitted <-- currentState - * inFlight - * updated - * inFlight - - If we are currently in the `uncommitted` state, calling - `transitionTo('inFlight')` would transition to the `created.inFlight` state, - while calling `transitionTo('updated.inFlight')` would transition to - the `updated.inFlight` state. - - Remember that *only events* should ever cause a state transition. You should - never call `transitionTo()` from outside a state's event handler. If you are - tempted to do so, create a new event and send that to the state manager. - - #### Flags - - Flags are Boolean values that can be used to introspect a record's current - state in a more user-friendly way than examining its state path. For example, - instead of doing this: - - ```javascript - var statePath = record.get('stateManager.currentPath'); - if (statePath === 'created.inFlight') { - doSomething(); - } - ``` - - You can say: - - ```javascript - if (record.get('isNew') && record.get('isSaving')) { - doSomething(); - } - ``` - - If your state does not set a value for a given flag, the value will - be inherited from its parent (or the first place in the state hierarchy - where it is defined). - - The current set of flags are defined below. If you want to add a new flag, - in addition to the area below, you will also need to declare it in the - `DS.Model` class. - - - * [isEmpty](DS.Model.html#property_isEmpty) - * [isLoading](DS.Model.html#property_isLoading) - * [isLoaded](DS.Model.html#property_isLoaded) - * [isDirty](DS.Model.html#property_isDirty) - * [isSaving](DS.Model.html#property_isSaving) - * [isDeleted](DS.Model.html#property_isDeleted) - * [isNew](DS.Model.html#property_isNew) - * [isValid](DS.Model.html#property_isValid) - - @namespace DS - @class RootState -*/ - -var hasDefinedProperties = function(object) { - // Ignore internal property defined by simulated `Ember.create`. - var names = Ember.keys(object); - var i, l, name; - for (i = 0, l = names.length; i < l; i++ ) { - name = names[i]; - if (object.hasOwnProperty(name) && object[name]) { return true; } - } - - return false; -}; - -var didSetProperty = function(record, context) { - if (context.value === context.originalValue) { - delete record._attributes[context.name]; - record.send('propertyWasReset', context.name); - } else if (context.value !== context.oldValue) { - record.send('becomeDirty'); - } - - record.updateRecordArraysLater(); -}; - -// Implementation notes: -// -// Each state has a boolean value for all of the following flags: -// -// * isLoaded: The record has a populated `data` property.

This - can be customized by setting the `tagName` property. The following view - class: - - ```javascript - ParagraphView = Ember.View.extend({ - tagName: 'em' - }); - ``` - - Would result in instances with the following HTML: - - ```html - - ``` - - ## HTML `class` Attribute - - The HTML `class` attribute of a view's tag can be set by providing a - `classNames` property that is set to an array of strings: - - ```javascript - MyView = Ember.View.extend({ - classNames: ['my-class', 'my-other-class'] - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
- ``` - - `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. The class name - will not be added if the value is `false` or `undefined`. - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['hovered'], - hovered: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
- ``` - - 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 -
- ``` - - Boolean value class name bindings whose property names are in a - camelCase-style format will be converted to a dasherized format: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['isUrgent'], - isUrgent: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
- ``` - - Class name bindings can also refer to object values that are found by - traversing a path relative to the view itself: - - ```javascript - MyView = Ember.View.extend({ - classNameBindings: ['messages.empty'] - messages: Ember.Object.create({ - empty: true - }) - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
- ``` - - If you want to add a class name for a property which evaluates to true and - and a different class name if it evaluates to false, you can pass a binding - like this: - - ```javascript - // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false - Ember.View.extend({ - classNameBindings: ['isEnabled:enabled:disabled'] - isEnabled: true - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html -
- ``` - - When isEnabled is `false`, the resulting HTML reprensentation looks like - this: - - ```html -
- ``` - - This syntax offers the convenience to add a class if a property is `false`: - - ```javascript - // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false - Ember.View.extend({ - classNameBindings: ['isEnabled::disabled'] - isEnabled: 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. If the value becomes `false` or `undefined` the class name - will be removed. - - Both `classNames` and `classNameBindings` are concatenated properties. 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' - }); - ``` - - If you have nested resources, your Handlebars template will look like this: - - ```html - - ``` - - And `templateName` property: - - ```javascript - AView = Ember.View.extend({ - templateName: 'posts/new' - }); - ``` - - 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. See [Ember.Handlebars.helpers.view](/api/classes/Ember.Handlebars.helpers.html#method_view) - for additional information. - - @class View - @namespace Ember - @extends Ember.CoreView -*/ -Ember.View = Ember.CoreView.extend({ - - concatenatedProperties: ['classNames', 'classNameBindings', 'attributeBindings'], - - /** - @property isView - @type Boolean - @default true - @static - */ - isView: true, - - // .......................................................... - // TEMPLATE SUPPORT - // - - /** - The name of the template to lookup if no template is provided. - - By default `Ember.View` will lookup a template with this name in - `Ember.TEMPLATES` (a shared global object). - - @property templateName - @type String - @default null - */ - templateName: null, - - /** - The name of the layout to lookup if no layout is provided. - - By default `Ember.View` will lookup a template with this name in - `Ember.TEMPLATES` (a shared global object). - - @property layoutName - @type String - @default null - */ - layoutName: null, - - /** - The template used to render the view.

  • the letter: B
    • -
  • the letter: C
    • -
- ``` - - Additional `tagName` pairs can be provided by adding to - `Ember.CollectionView.CONTAINER_MAP ` - - ```javascript - Ember.CollectionView.CONTAINER_MAP['article'] = 'section' - ``` - - ## Programmatic creation of child views - - For cases where additional customization beyond the use of a single - `itemViewClass` or `tagName` matching is required CollectionView's - `createChildView` method can be overidden: - - ```javascript - CustomCollectionView = Ember.CollectionView.extend({ - createChildView: function(viewClass, attrs) { - if (attrs.content.kind == 'album') { - viewClass = App.AlbumView; - } else { - viewClass = App.SongView; - } - return this._super(viewClass, attrs); - } - }); - ``` - - ## Empty View - - You can provide an `Ember.View` subclass to the `Ember.CollectionView` - instance as its `emptyView` property. If the `content` property of a - `CollectionView` is set to `null` or an empty array, an instance of this view - will be the `CollectionView`s only child. - - ```javascript - aListWithNothing = Ember.CollectionView.create({ - classNames: ['nothing'] - content: null, - emptyView: Ember.View.extend({ - template: Ember.Handlebars.compile("The collection is empty") - }) - }); - - aListWithNothing.appendTo('body'); - ``` - - Will result in the following HTML structure - - ```html -
-
- The collection is empty -

Each string can be: - - * a string return value of an object's property. - * a boolean return value of an object's property - * a hard-coded value - - A string return value works identically to other uses of `bind-attr`. The - return value of the property will become the value of the attribute. For - example, the following view and template: - - ```javascript - AView = Ember.View.extend({ - someProperty: function() { - return "aValue"; - }.property() - }) - ``` - - ```handlebars - - ``` - - A boolean return value will insert a specified class name if the property - returns `true` and remove the class name if the property returns `false`. - - A class name is provided via the syntax - `somePropertyName:class-name-if-true`. - - ```javascript - AView = Ember.View.extend({ - someBool: true - }) - ``` - - ```handlebars - - ``` - - Result in the following rendered output: - - ```html - - ``` - - An additional section of the binding can be provided if you want to - replace the existing class instead of removing it when the boolean - value changes: - - ```handlebars - - ``` - - A hard-coded value can be used by prepending `:` to the desired - class name: `:class-name-to-always-apply`. - - ```handlebars - - ``` - - Results in the following rendered output: - - ```html - - ``` - - All three strategies - string return value, boolean return value, and - hard-coded value – can be combined in a single declaration: - - ```handlebars - - ``` - - @method bind-attr - @for Ember.Handlebars.helpers - @param {Hash} options - @return {String} HTML string -*/ -EmberHandlebars.registerHelper('bind-attr', function bindAttrHelper(options) { - - var attrs = options.hash; - - - var view = options.data.view; - var ret = []; - var ctx = this; - - // Generate a unique id for this element.

    - ``` - - ### Supplying a different view class - - `{{view}}` can take an optional first argument before its supplied options to - specify a path to a custom view class. - - ```handlebars - {{#view "MyApp.CustomView"}} - hello. - {{/view}} - ``` - - The first argument can also be a relative path accessible from the current - context. - - ```javascript - MyApp = Ember.Application.create({}); - MyApp.OuterView = Ember.View.extend({ - innerViewClass: Ember.View.extend({ - classNames: ['a-custom-view-class-as-property'] - }), - template: Ember.Handlebars.compile('{{#view "view.innerViewClass"}} hi {{/view}}') - }); - - MyApp.OuterView.create().appendTo('body'); - ``` - - Will result in the following HTML: - - ```html -
    -
    - hi -
    -
    - ``` - - ### Blockless use - - If you supply a custom `Ember.View` subclass that specifies its own template - or provide a `templateName` option to `{{view}}` it can be used without - supplying a block. 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}}`. The `Ember.View` instance - will be referenced as a property of its parent view by this name. - - ```javascript - aView = Ember.View.create({ - template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}') - }); - - aView.appendTo('body'); - aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper - ``` - - @method view - @for Ember.Handlebars.helpers - @param {String} path - @param {Hash} options - @return {String} HTML string -*/ -EmberHandlebars.registerHelper('view', function viewHelper(path, options) { - - // If no path is provided, treat path param as options. - if (path && path.data && path.data.isRenderData) { - options = path; - path = "Ember.View"; - } - - return EmberHandlebars.ViewHelper.helper(this, path, options); -}); - - -})(); - - - -(function() { -// TODO: Don't require all of this module -/** -@module ember -@submodule ember-handlebars -*/ - -var get = Ember.get, handlebarsGet = Ember.Handlebars.get, fmt = Ember.String.fmt; - -/** - `{{collection}}` is a `Ember.Handlebars` helper for adding instances of - `Ember.CollectionView` to a template. See [Ember.CollectionView](/api/classes/Ember.CollectionView.html) - for additional information on how a `CollectionView` functions. - - `{{collection}}`'s primary use is as a block helper with a `contentBinding` - option pointing towards an `Ember.Array`-compatible object. An `Ember.View` - instance will be created for each item in its `content` property. Each view - will have its own `content` property set to the appropriate item in the - collection. - - The provided block will be applied as the template for each item's view. - - Given an empty `` the following template: - - ```handlebars - {{#collection contentBinding="App.items"}} - Hi {{view.content.name}} - {{/collection}} - ``` - - And the following application code - - ```javascript - App = Ember.Application.create() - App.items = [ - Ember.Object.create({name: 'Dave'}), - Ember.Object.create({name: 'Mary'}), - Ember.Object.create({name: 'Sara'}) - ] - ``` - - Will result in the HTML structure below - - ```html -
    -
    Hi Dave
    -
    Hi Mary
    -
    Hi Sara
    -
    - ``` - - ### Blockless Use - - If you provide an `itemViewClass` option that has its own `template` you can - omit the block. - - The following template: - - ```handlebars - {{collection contentBinding="App.items" itemViewClass="App.AnItemView"}} - ``` - - And application code - - ```javascript - App = Ember.Application.create(); - App.items = [ - Ember.Object.create({name: 'Dave'}), - Ember.Object.create({name: 'Mary'}), - Ember.Object.create({name: 'Sara'}) - ]; - - App.AnItemView = Ember.View.extend({ - template: Ember.Handlebars.compile("Greetings {{view.content.name}}") - }); - ``` - - Will result in the HTML structure below - - ```html -
    -
    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 -

    - ``` - - 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 eachHelper(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.

This can - be overridden for a single use of `{{link-to}}` by supplying - a `tagName` option: - - ```handlebars - {{#link-to 'photoGallery' tagName="li"}} - Great Hamster Photos - {{/link-to}} - ``` - - ```html -
  • - 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. For example, if the application's - current route is 'photoGallery.recent' the following - use of `{{link-to}}`: - - ```handlebars - {{#link-to 'photoGallery.recent'}} - Great Hamster Photos from the last week - {{/link-to}} - ``` - - will result in - - ```html -     - Great Hamster Photos - - ``` - - The CSS class name used for active classes can be customized - for a single use of `{{link-to}}` by passing an `activeClass` - option: - - ```handlebars - {{#link-to 'photoGallery.recent' activeClass="current-url"}} - Great Hamster Photos from the last week - {{/link-to}} - ``` - - ```html - - Great Hamster Photos - - ``` - - To override this option for your entire application, see - "Overriding Application-wide Defaults". - - ### Supplying a model - An optional model argument can be used for routes whose - paths contain dynamic segments. This argument will become - the model context of the linked route: - - ```javascript - App.Router.map(function() { - this.resource("photoGallery", {path: "hamster-photos/:photo_id"}); - }); - ``` - - ```handlebars - {{#link-to 'photoGallery' aPhoto}} - {{aPhoto.title}} - {{/link-to}} - ``` - - ```html - - Tomster - - ``` - - ### Supplying multiple models - For deep-linking to route paths that contain multiple - dynamic segments, multiple model arguments can be used. - As the router transitions through the route path, each - supplied model argument will become the context for the - route with the dynamic segments: - - ```javascript - App.Router.map(function() { - this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function() { - this.route("comment", {path: "comments/:comment_id"}); - }); - }); - ``` - This argument will become the model context of the linked route: - - ```handlebars - {{#link-to 'photoGallery.comment' aPhoto comment}} - {{comment.body}} - {{/link-to}} - ``` - - ```html - - A+++ would snuggle again. - - ``` - - ### Supplying an explicit dynamic segment value - If you don't have a model object available to pass to `{{link-to}}`, - an optional string or integer argument can be passed for routes whose - paths contain dynamic segments. 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. - - ### Allowing Default Action - - By default the `{{link-to}}` helper prevents the default browser action - by calling `preventDefault()` as this sort of action bubbling is normally - handled internally and we do not want to take the browser to a new URL (for - example). - - If you need to override this behavior specify `preventDefault=false` in - your template: - - ```handlebars - {{#link-to 'photoGallery' aPhotoId preventDefault=false}} - {{aPhotoId.title}} - {{/link-to}} - ``` - - ### 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. Be sure to also - check out inherited properties of `LinkView`. - - ### Overriding Application-wide Defaults - ``{{link-to}}`` creates an instance of Ember.LinkView - for rendering. To override options for your entire - application, reopen Ember.LinkView and supply the - desired values: - - ``` javascript - Ember.LinkView.reopen({ - activeClass: "is-active", - tagName: 'li' - }) - ``` - - It is also possible to override the default event in - this manner: - - ``` javascript - Ember.LinkView.reopen({ - eventName: 'customEventName' - }); - ``` - - @method link-to - @for Ember.Handlebars.helpers - @param {String} routeName - @param {Object} [context]* - @param [options] {Object} Handlebars key/value pairs of options, you can override any property of Ember.LinkView - @return {String} HTML string - @see {Ember.LinkView} - */ - Ember.Handlebars.registerHelper('link-to', function linkToHelper(name) { - var options = [].slice.call(arguments, -1)[0], - params = [].slice.call(arguments, 0, -1), - hash = options.hash; - - hash.disabledBinding = hash.disabledWhen; - - if (!options.fn) { - var linkTitle = params.shift(); - var linkType = options.types.shift(); - var context = this; - if (linkType === 'ID') { - options.linkTextPath = linkTitle; - options.fn = function() { - return Ember.Handlebars.getEscaped(context, linkTitle, options); - }; - } else { - options.fn = function() { - return linkTitle; - }; - } - } - - hash.parameters = { - context: this, - options: options, - params: params - }; - - return Ember.Handlebars.helpers.view.call(this, LinkView, options); - }); - - /** - See [link-to](/api/classes/Ember.Handlebars.helpers.html#method_link-to) - - @method linkTo - @for Ember.Handlebars.helpers - @deprecated - @param {String} routeName - @param {Object} [context]* - @return {String} HTML string - */ - Ember.Handlebars.registerHelper('linkTo', function linkToHelper() { - return Ember.Handlebars.helpers['link-to'].apply(this, arguments); - }); -}); - - - -})(); - - - -(function() { -/** -@module ember -@submodule ember-routing -*/ - -var get = Ember.get, set = Ember.set; -Ember.onLoad('Ember.Handlebars', function(Handlebars) { - /** - @module ember - @submodule ember-routing - */ - - Handlebars.OutletView = Ember.ContainerView.extend(Ember._Metamorph); - - /** - The `outlet` helper is a placeholder that the router will fill in with - the appropriate template based on the current state of the application. - - ``` handlebars - {{outlet}} - ``` - - By default, a template based on Ember's naming conventions will be rendered - into the `outlet` (e.g. `App.PostsRoute` will render the `posts` template). - - You can render a different template by using the `render()` method in the - route's `renderTemplate` hook.

    - click me -
    - ``` - - And application code - - ```javascript - App.ApplicationController = Ember.Controller.extend({ - actions: { - anActionName: function() { - } - } - }); - ``` - - Will result in the following rendered HTML - - ```html -
    -
    - click me -
    -
    - ``` - - Clicking "click me" will trigger the `anActionName` action of the - `App.ApplicationController`. In this case, no additional parameters will be passed. - - If you provide additional parameters to the helper: - - ```handlebars - - ``` - - Those parameters will be passed along as arguments to the JavaScript - function implementing the action. - - ### Event Propagation - - Events triggered through the action helper will automatically have - `.preventDefault()` called on them. You do not need to do so in your event - handlers. If you need to allow event propagation (to handle file inputs for - example) you can supply the `preventDefault=false` option to the `{{action}}` helper: - - ```handlebars -
    - - -
    - ``` - - To disable bubbling, pass `bubbles=false` to the helper: - - ```handlebars - - ``` - - If you need the default handler to trigger you should either register your - own event handler, or use event methods on your view class. 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. These - parameters are passed along as the arguments to the JavaScript function - implementing the action. - - ```handlebars - {{#each person in people}} -
    - click me -
    - {{/each}} - ``` - - Clicking "click me" will trigger the `edit` method on the current controller - with the value of `person` as a parameter. - - @method action - @for Ember.Handlebars.helpers - @param {String} actionName - @param {Object} [context]* - @param {Hash} options - */ - EmberHandlebars.registerHelper('action', function actionHelper(actionName) { - var options = arguments[arguments.length - 1], - contexts = a_slice.call(arguments, 1, -1); - - var hash = options.hash, - controller; - - // create a hash to pass along to registerAction - var action = { - eventName: hash.on || "click" - }; - - action.parameters = { - context: this, - options: options, - params: contexts - }; - - action.view = options.data.view; - - var root, target; - - if (hash.target) { - root = this; - target = hash.target; - } else if (controller = options.data.keywords.controller) { - root = controller; - } - - action.target = { root: root, target: target, options: options }; - action.bubbles = hash.bubbles; - action.preventDefault = hash.preventDefault; - - var actionId = ActionHelper.registerAction(actionName, action, hash.allowedKeys); - return new SafeString('data-ember-action="' + actionId + '"'); - }); - -}); - -})(); - - - -(function() { - -})(); - - - -(function() { -/** -@module ember -@submodule ember-routing -*/ - -var get = Ember.get, set = Ember.set; - -Ember.ControllerMixin.reopen({ - /** - Transition the application into another route.

- if (resolvedTemplate) { return resolvedTemplate; } - return Ember.TEMPLATES['not_found']; - } - }) - }); - ``` - - Some examples of how names are resolved: - - ``` - 'template:post' //=> Ember.TEMPLATES['post'] - 'template:posts/byline' //=> Ember.TEMPLATES['posts/byline'] - 'template:posts.byline' //=> Ember.TEMPLATES['posts/byline'] - 'template:blogPost' //=> Ember.TEMPLATES['blogPost'] - // OR - // Ember.TEMPLATES['blog_post'] - 'controller:post' //=> App.PostController - 'controller:posts.index' //=> App.PostsIndexController - 'controller:blog/post' //=> Blog.PostController - 'controller:basic' //=> Ember.Controller - 'route:post' //=> App.PostRoute - 'route:posts.index' //=> App.PostsIndexRoute - 'route:blog/post' //=> Blog.PostRoute - 'route:basic' //=> Ember.Route - 'view:post' //=> App.PostView - 'view:posts.index' //=> App.PostsIndexView - 'view:blog/post' //=> Blog.PostView - 'view:basic' //=> Ember.View - 'foo:post' //=> App.PostFoo - 'model:post' //=> App.Post - ``` - - @class DefaultResolver - @namespace Ember - @extends Ember.Object -*/ -Ember.DefaultResolver = Ember.Object.extend({ - /** - This will be set to the Application instance when it is - created. - - @property namespace - */ - namespace: null, - - normalize: function(fullName) { - var split = fullName.split(':', 2), - type = split[0], - name = split[1];

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.
