DataTable.BodyView Class

Extends View
Module: datatable-body
Parent Module: datatable

Available since 3.5.0

View class responsible for rendering the <tbody> section of a table. Used as the default bodyView for Y.DataTable.Base and Y.DataTable classes.

Translates the provided modelList into a rendered <tbody> based on the data in the constituent Models, altered or amended by any special column configurations.

The columns configuration, passed to the constructor, determines which columns will be rendered.

The rendering process involves constructing an HTML template for a complete row of data, built by concatenating a customized copy of the instance's CELL_TEMPLATE into the ROW_TEMPLATE once for each column. This template is then populated with values from each Model in the modelList, aggregating a complete HTML string of all row and column data. A <tbody> Node is then created from the markup and any column nodeFormatters are applied.

Supported properties of the column objects include:

  • key - Used to link a column to an attribute in a Model.
  • name - Used for columns that don't relate to an attribute in the Model (formatter or nodeFormatter only) if the implementer wants a predictable name to refer to in their CSS.
  • cellTemplate - Overrides the instance's CELL_TEMPLATE for cells in this column only.
  • formatter - Used to customize or override the content value from the Model. These do not have access to the cell or row Nodes and should return string (HTML) content.
  • nodeFormatter - Used to provide content for a cell as well as perform any custom modifications on the cell or row Node that could not be performed by formatters. Should be used sparingly for better performance.
  • emptyCellValue - String (HTML) value to use if the Model data for a column, or the content generated by a formatter, is the empty string, null, or undefined.
  • allowHTML - Set to true if a column value, formatter, or emptyCellValue can contain HTML. This defaults to false to protect against XSS.
  • className - Space delimited CSS classes to add to all <td>s in a column.

A column formatter can be:

  • a function, as described below.
  • a string which can be:
    • the name of a pre-defined formatter function which can be located in the Y.DataTable.BodyView.Formatters hash using the value of the formatter property as the index.
    • A template that can use the {value} placeholder to include the value for the current cell or the name of any field in the underlaying model also enclosed in curly braces. Any number and type of these placeholders can be used.

Column formatters are passed an object (o) with the following properties:

  • value - The current value of the column's associated attribute, if any.
  • data - An object map of Model keys to their current values.
  • record - The Model instance.
  • column - The column configuration object for the current column.
  • className - Initially empty string to allow formatters to add CSS classes to the cell's <td>.
  • rowIndex - The zero-based row number.
  • rowClass - Initially empty string to allow formatters to add CSS classes to the cell's containing row <tr>.

They may return a value or update o.value to assign specific HTML content. A returned value has higher precedence.

Column nodeFormatters are passed an object (o) with the following properties:

  • value - The current value of the column's associated attribute, if any.
  • td - The <td> Node instance.
  • cell - The <div> liner Node instance if present, otherwise, the <td>. When adding content to the cell, prefer appending into this property.
  • data - An object map of Model keys to their current values.
  • record - The Model instance.
  • column - The column configuration object for the current column.
  • rowIndex - The zero-based row number.

They are expected to inject content into the cell's Node directly, including any "empty" cell content. Each nodeFormatter will have access through the Node API to all cells and rows in the <tbody>, but not to the <table>, as it will not be attached yet.

If a nodeFormatter returns false, the o.td and o.cell Nodes will be destroy()ed to remove them from the Node cache and free up memory. The DOM elements will remain as will any content added to them. It is highly advisable to always return false from your nodeFormatters.

Events

Methods

_addAttrs

(
  • cfgs
  • values
  • lazy
)
private

Implementation behind the public addAttrs method.

This method is invoked directly by get if it encounters a scenario in which an attribute's valueFn attempts to obtain the value an attribute in the same group of attributes, which has not yet been added (on demand initialization).

Parameters:

  • cfgs Object

    An object with attribute name/configuration pairs.

  • values Object

    An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.

  • lazy Boolean

    Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

_addLazyAttr

(
  • name
  • [lazyCfg]
)
private

Finishes initializing an attribute which has been lazily added.

Parameters:

  • name Object

    The name of the attribute

  • [lazyCfg] Object optional

    Optional config hash for the attribute. This is added for performance along the critical path, where the calling method has already obtained lazy config from state.

_addOutOfOrder

(
  • name
  • cfg
)
private

Utility method used by get/set to add attributes encountered out of order when calling addAttrs().

For example, if:

this.addAttrs({
     foo: {
         setter: function() {
            // make sure this bar is available when foo is added
            this.get("bar");
         }
     },
     bar: {
         value: ...
     }
});

Parameters:

  • name String

    attribute name

  • cfg Object

    attribute configuration

_afterColumnsChange

(
  • e
)
protected

Defined in datatable/js/body.js:608

Available since 3.5.0

Handles changes in the source's columns attribute. Redraws the table data.

Parameters:

_afterContainerChange

() protected

Inherited from View: app/js/view.js:357

Available since 3.5.0

Handles containerChange events. Detaches event handlers from the old container (if any) and attaches them to the new container.

Right now the container attr is initOnly so this event should only ever fire the first time the container is created, but in the future (once Y.App can handle it) we may allow runtime container changes.

_afterDataChange

(
  • e
)
protected

Defined in datatable/js/body.js:627

Available since 3.5.0

Handles modelList changes, including additions, deletions, and updates.

Modifies the existing table DOM accordingly.

Parameters:

_afterModelListChange

(
  • e
)
protected

Defined in datatable/js/body.js:748

Available since 3.6.0

Handles replacement of the modelList.

Rerenders the <tbody> contents.

Parameters:

_aggregateAttrs

(
  • allAttrs
)
Object private

A helper method, used by _initHierarchyData to aggregate attribute configuration across the instances class hierarchy.

The method will protect the attribute configuration value to protect the statically defined default value in ATTRS if required (if the value is an object literal, array or the attribute configuration has cloneDefaultValue set to shallow or deep).

Parameters:

  • allAttrs Array

    An array of ATTRS definitions across classes in the hierarchy (subclass first, Base last)

Returns:

Object:

The aggregate set of ATTRS definitions for the instance

_applyNodeFormatters

(
  • tbody
  • displayCols
)
protected

Defined in datatable/js/body.js:772

Available since 3.5.0

Iterates the modelList, and calls any nodeFormatters found in the columns param on the appropriate cell Nodes in the tbody.

Parameters:

  • tbody Node

    The <tbody> Node whose columns to update

  • displayCols Object[]

    The column configurations

_attrCfgHash

() private

Utility method to define the attribute hash used to filter/whitelist property mixes for this class for iteration performance reasons.

_baseDestroy

() private

Internal destroy implementation for BaseCore

_baseInit

() private

Internal initialization implementation for BaseCore

_cloneDefaultValue

(
  • cfg
)
private

This method assumes that the value has already been checked to be an object. Since it's on a critical path, we don't want to re-do the check.

Parameters:

_createDataHTML

(
  • displayCols
)
String protected

Defined in datatable/js/body.js:863

Available since 3.5.0

Iterates the modelList and applies each Model to the _rowTemplate, allowing any column formatter or emptyCellValue to override cell content for the appropriate column. The aggregated HTML string is returned.

Parameters:

  • displayCols Object[]

    The column configurations to customize the generated cell content or class names

Returns:

String:

The markup for all Models in the modelList, each applied to the _rowTemplate

_createRowHTML

(
  • model
  • index
  • displayCols
)
String protected

Defined in datatable/js/body.js:890

Available since 3.5.0

Applies the data of a given Model, modified by any column formatters and supplemented by other template values to the instance's _rowTemplate (see _createRowTemplate). The generated string is then returned.

The data from Model's attributes is fetched by toJSON and this data object is appended with other properties to supply values to {placeholders} in the template. For a template generated from a Model with 'foo' and 'bar' attributes, the data object would end up with the following properties before being used to populate the _rowTemplate:

  • clientID - From Model, used the assign the <tr>'s 'id' attribute.
  • foo - The value to populate the 'foo' column cell content. This value will be the value stored in the Model's foo attribute, or the result of the column's formatter if assigned. If the value is '', null, or undefined, and the column's emptyCellValue is assigned, that value will be used.
  • bar - Same for the 'bar' column cell content.
  • foo-className - String of CSS classes to apply to the <td>.
  • bar-className - Same.
  • rowClass - String of CSS classes to apply to the <tr>. This will be the odd/even class per the specified index plus any additional classes assigned by column formatters (via o.rowClass).

Because this object is available to formatters, any additional properties can be added to fill in custom {placeholders} in the _rowTemplate.

Parameters:

  • model Model

    The Model instance to apply to the row template

  • index Number

    The index the row will be appearing

  • displayCols Object[]

    The column configurations

Returns:

String:

The markup for the provided Model, less any nodeFormatters

_setStateVal

(
  • name
  • value
)
private

Sets the stored value for the attribute, in either the internal state object, or the state proxy if it exits

Parameters:

  • name String

    The name of the attribute

  • value Any

    The value of the attribute

addAttr

(
  • name
  • config
  • lazy
)
Object chainable

Adds an attribute with the provided configuration to the host object.

The config argument object supports the following properties:

value <Any>
The initial value to set on the attribute
valueFn <Function | String>

A function, which will return the initial value to set on the attribute. This is useful for cases where the attribute configuration is defined statically, but needs to reference the host instance ("this") to obtain an initial value. If both the value and valueFn properties are defined, the value returned by the valueFn has precedence over the value property, unless it returns undefined, in which case the value property is used.

valueFn can also be set to a string, representing the name of the instance method to be used to retrieve the value.

readOnly <boolean>
Whether or not the attribute is read only. Attributes having readOnly set to true cannot be modified by invoking the set method.
writeOnce <boolean> or <string>
Whether or not the attribute is "write once". Attributes having writeOnce set to true, can only have their values set once, be it through the default configuration, constructor configuration arguments, or by invoking set.

The writeOnce attribute can also be set to the string "initOnly", in which case the attribute can only be set during initialization (when used with Base, this means it can only be set during construction)

setter <Function | String>

The setter function used to massage or normalize the value passed to the set method for the attribute. The value returned by the setter will be the final stored value. Returning Attribute.INVALID_VALUE, from the setter will prevent the value from being stored.

setter can also be set to a string, representing the name of the instance method to be used as the setter function.

getter <Function | String>

The getter function used to massage or normalize the value returned by the get method for the attribute. The value returned by the getter function is the value which will be returned to the user when they invoke get.

getter can also be set to a string, representing the name of the instance method to be used as the getter function.

validator <Function | String>

The validator function invoked prior to setting the stored value. Returning false from the validator function will prevent the value from being stored.

validator can also be set to a string, representing the name of the instance method to be used as the validator function.

lazyAdd <boolean>
Whether or not to delay initialization of the attribute until the first call to get/set it. This flag can be used to over-ride lazy initialization on a per attribute basis, when adding multiple attributes through the addAttrs method.

The setter, getter and validator are invoked with the value and name passed in as the first and second arguments, and with the context ("this") set to the host object.

Configuration properties outside of the list mentioned above are considered private properties used internally by attribute, and are not intended for public use.

Parameters:

  • name String

    The name of the attribute.

  • config Object

    An object with attribute configuration property/value pairs, specifying the configuration for the attribute.

    NOTE: The configuration object is modified when adding an attribute, so if you need to protect the original values, you will need to merge the object.

  • lazy Boolean

    (optional) Whether or not to add this attribute lazily (on the first call to get/set).

Returns:

Object:

A reference to the host object.

addAttrs

(
  • cfgs
  • values
  • lazy
)
Object chainable

Configures a group of attributes, and sets initial values.

NOTE: This method does not isolate the configuration object by merging/cloning. The caller is responsible for merging/cloning the configuration object if required.

Parameters:

  • cfgs Object

    An object with attribute name/configuration pairs.

  • values Object

    An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.

  • lazy Boolean

    Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

Returns:

Object:

A reference to the host object.

addTarget

(
  • o
)
chainable

Registers another EventTarget as a bubble target. Bubble order is determined by the order registered. Multiple targets can be specified.

Events can only bubble if emitFacade is true.

Included in the event-custom-complex submodule.

Parameters:

after

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle

    The name of the event

  • fn Function

    The callback to execute in response to the event

  • [context] Object optional

    Override this object in callback

A subscription handle capable of detaching the subscription

attachEvents

(
  • [events]
)
chainable

Inherited from View: app/js/view.js:181

Attaches delegated event handlers to this view's container element. This method is called internally to subscribe to events configured in the events attribute when the view is initialized.

You may override this method to customize the event attaching logic.

Parameters:

Parameters:

  • name String

    The name of the attribute to check.

Returns:

Boolean:

true if an attribute with the given name has been added, false if it hasn't. This method will return true for lazily added attributes.

before

()

Executes the callback before a DOM event, custom event or method. If the first argument is a function, it is assumed the target is a method. For DOM and custom events, this is an alias for Y.on.

For DOM and custom events: type, callback, context, 0-n arguments

For methods: callback, object (method host), methodName, context, 0-n arguments

Returns:

detach handle

bindUI

Boolean:

the aggregated return value from Event.Custom.fire

create

(
  • [container]
)
Node

Inherited from View: app/js/view.js:233

Creates and returns a container node for this view.

By default, the container is created from the HTML template specified in the containerTemplate property, and is not added to the DOM automatically.

You may override this method to customize how the container node is created (such as by rendering it from a custom template format). Your method must return a Y.Node instance.

Parameters:

  • [container] HTMLElement | Node | String optional

    Selector string, Y.Node instance, or DOM element to use at the container node.

Returns:

Node:

Node instance of the created container node.

destroy

(
  • [options]
)
chainable

Inherited from BaseObservable but overwritten in app/js/view.js:146

Destroys this View, detaching any DOM events and optionally also destroying its container node.

By default, the container node will not be destroyed. Pass an options object with a truthy remove property to destroy the container as well.

Parameters:

  • [options] Object optional

    Options.

    • [remove=false] Boolean optional

      If true, this View's container will be removed from the DOM and destroyed as well.

destructor

() protected

Defined in datatable/js/body.js:1109

Available since 3.5.0

Destroys the instance.

detach

(
  • type
  • fn
  • context
)
EventTarget

Detach one or more listeners the from the specified event

Parameters:

  • type String | Object

    Either the handle to the subscriber or the type of event. If the type is not specified, it will attempt to remove the listener from all hosted events.

  • fn Function

    The subscribed function to unsubscribe, if not supplied, all subscribers will be removed.

  • context Object

    The custom object passed to subscribe. This is optional, but if supplied will be used to disambiguate multiple listeners that are the same (e.g., you subscribe many object using a function that lives on the prototype)

Returns:

EventTarget:

the host

detachAll

(
  • type
)

Removes all listeners from the specified event. If the event type is not specified, all listeners from all hosted custom events will be removed.

Parameters:

  • type String

    The type, or name of the event

detachEvents

() chainable

Inherited from View: app/js/view.js:253

Detaches DOM events that have previously been attached to the container by attachEvents().

fire

(
  • type
  • arguments
)
Boolean

Fire a custom event by name. The callback functions will be executed from the context specified when the event was created, and with the following parameters.

The first argument is the event type, and any additional arguments are passed to the listeners as parameters. If the first of these is an object literal, and the event is configured to emit an event facade, that object is mixed into the event facade and the facade is provided in place of the original object.

If the custom event object hasn't been created, then the event hasn't been published and it has no subscribers. For performance sake, we immediate exit in this case. This means the event won't bubble, so if the intention is that a bubble target be notified, the event must be published on this object first.

Parameters:

  • type String | Object

    The type of the event, or an object that contains a 'type' property.

  • arguments Object*

    an arbitrary set of parameters to pass to the handler. If the first of these is an object literal and the event is configured to emit an event facade, the event facade will replace that parameter after the properties the object literal contains are copied to the event facade.

Returns:

Boolean:

True if the whole lifecycle of the event went through, false if at any point the event propagation was halted.

get

(
  • name
)
Any

Returns the current value of the attribute. If the attribute has been configured with a 'getter' function, this method will delegate to the 'getter' to obtain the value of the attribute.

Parameters:

  • name String

    The name of the attribute. If the value of the attribute is an Object, dot notation can be used to obtain the value of a property of the object (e.g. get("x.y.z"))

Returns:

Any:

The value of the attribute

getAttrs

(
  • attrs
)
Object

Gets multiple attribute values.

Parameters:

  • attrs String[] | Boolean

    Optional. An array of attribute names. If omitted, all attribute values are returned. If set to true, all attributes modified from their initial values are returned.

Returns:

Object:

An object with attribute name/value pairs.

getCell

  • seed
  • [shift]
)
Node

Defined in datatable/js/body.js:194

Optionally, include an offset array or string to return a cell near the cell identified by the seed. The offset can be an array containing the number of rows to shift followed by the number of columns to shift, or one of "above", "below", "next", or "previous".

// Previous cell in the previous row
var cell = table.getCell(e.target, [-1, -1]);

// Next cell var cell = table.getCell(e.target, 'next'); var cell = table.getCell(e.target, [0, 1];

    Object with configuration property name/value pairs

Returns:

BaseCore:

A reference to this object

initializer

(
  • config
)
protected

Defined in datatable/js/body.js:1153

Available since 3.5.0

Initializes the instance. Reads the following configuration properties in addition to the instance attributes:

  • columns - (REQUIRED) The initial column information
  • host - The object to serve as source of truth for column info and
            for generating class names

Parameters:

  • config Object

    Configuration data

modifyAttr

(
  • name
  • config
)

Updates the configuration of an attribute which has already been added.

The properties which can be modified through this interface are limited to the following subset of attributes, which can be safely modified after a value has already been set on the attribute:

readOnly;
writeOnce;
broadcast; and
getter.

Note: New attributes cannot be added using this interface. New attributes must be added using addAttr, or an appropriate manner for a class which utilises Attributes (e.g. the ATTRS property in Base).

Parameters:

  • name String

    The name of the attribute whose configuration is to be updated.

  • config Object

    An object with configuration property/value pairs, specifying the configuration properties to modify.

on

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle

Subscribe a callback function to a custom event fired by this object or from an object that bubbles its events to this object.

Callback functions for events published with emitFacade = true will receive an EventFacade as the first argument (typically named "e"). These callbacks can then call e.preventDefault() to disable the behavior published to that event's defaultFn. See the EventFacade API for all available properties and methods. Subscribers to non-emitFacade events will receive the arguments passed to fire() after the event name.

To subscribe to multiple events at once, pass an object as the first argument, where the key:value pairs correspond to the eventName:callback, or pass an array of event names as the first argument to subscribe to all listed events with the same callback.

Returning false from a callback is supported as an alternative to calling e.preventDefault(); e.stopPropagation();. However, it is recommended to use the event methods whenever possible.

Parameters:

  • type String

    The name of the event

  • fn Function

    The callback to execute in response to the event

  • [context] Object optional

    Override this object in callback

Parameters:

render

() chainable

Inherited from View but overwritten in datatable/js/body.js:346

Available since 3.5.0

Creates the table's <tbody> content by assembling markup generated by populating the ROW\_TEMPLATE, and CELL\_TEMPLATE templates with content from the columns and modelList attributes.

The rendering process happens in three stages:

  1. A row template is assembled from the columns attribute (see _createRowTemplate)

  2. An HTML string is built up by concatenating the application of the data in each Model in the modelList to the row template. For cells with formatters, the function is called to generate cell content. Cells with nodeFormatters are ignored. For all other cells, the data value from the Model attribute for the given column key is used. The accumulated row markup is then inserted into the container.

  3. If any column is configured with a nodeFormatter, the modelList is iterated again to apply the nodeFormatters.

Supported properties of the column objects include:

  • key - Used to link a column to an attribute in a Model.
  • name - Used for columns that don't relate to an attribute in the Model (formatter or nodeFormatter only) if the implementer wants a predictable name to refer to in their CSS.
  • cellTemplate - Overrides the instance's CELL_TEMPLATE for cells in this column only.
  • formatter - Used to customize or override the content value from the Model. These do not have access to the cell or row Nodes and should return string (HTML) content.
  • nodeFormatter - Used to provide content for a cell as well as perform any custom modifications on the cell or row Node that could not be performed by formatters. Should be used sparingly for better performance.
  • emptyCellValue - String (HTML) value to use if the Model data for a column, or the content generated by a formatter, is the empty string, null, or undefined.
  • allowHTML - Set to true if a column value, formatter, or emptyCellValue can contain HTML. This defaults to false to protect against XSS.
  • className - Space delimited CSS classes to add to all <td>s in a column.

Column formatters are passed an object (o) with the following properties:

  • value - The current value of the column's associated attribute, if any.
  • data - An object map of Model keys to their current values.
  • record - The Model instance.
  • column - The column configuration object for the current column.
  • className - Initially empty string to allow formatters to add CSS classes to the cell's <td>.
  • rowIndex - The zero-based row number.
  • rowClass - Initially empty string to allow formatters to add CSS classes to the cell's containing row <tr>.

They may return a value or update o.value to assign specific HTML content. A returned value has higher precedence.

Column nodeFormatters are passed an object (o) with the following properties:

  • value - The current value of the column's associated attribute, if any.
  • td - The <td> Node instance.
  • cell - The <div> liner Node instance if present, otherwise, the <td>. When adding content to the cell, prefer appending into this property.
  • data - An object map of Model keys to their current values.
  • record - The Model instance.
  • column - The column configuration object for the current column.
  • rowIndex - The zero-based row number.

They are expected to inject content into the cell's Node directly, including any "empty" cell content. Each nodeFormatter will have access through the Node API to all cells and rows in the <tbody>, but not to the <table>, as it will not be attached yet.

If a nodeFormatter returns false, the o.td and o.cell Nodes will be destroy()ed to remove them from the Node cache and free up memory. The DOM elements will remain as will any content added to them. It is highly advisable to always return false from your nodeFormatters.

Properties

_allowAdHocAttrs

Boolean protected

Inherited from BaseCore but overwritten in app/js/view.js:111

Available since 3.5.0

This tells Y.Base that it should create ad-hoc attributes for config properties passed to View's constructor. This makes it possible to instantiate a view and set a bunch of attributes without having to subclass Y.View and declare all those attributes first.

Default: true

_eventHandles

Object protected

Defined in datatable/js/body.js:1120

Available since 3.5.0

Holds the event subscriptions needing to be detached when the instance is destroy()ed.

Default: undefined (initially unset)

_rowTemplate

String protected

Defined in datatable/js/body.js:1180

Available since 3.5.0

The HTML template used to create a full row of markup for a single Model in the modelList plus any customizations defined in the column configurations.

Default: (initially unset)

CELL_TEMPLATE

events

Object

Inherited from View: app/js/view.js:50

Hash of CSS selectors mapped to events to delegate to elements matching those selectors.

CSS selectors are relative to the container element. Events are attached to the container, and delegation is used so that subscribers are only notified of events that occur on elements inside the container that match the specified selectors. This allows the container's contents to be re- rendered as needed without losing event subscriptions.

Event handlers can be specified either as functions or as strings that map to function names on this view instance or its prototype.

The this object in event handlers will refer to this view instance. If you'd prefer this to be something else, use Y.bind() to bind a custom this object.

Default: {}

Example:

var view = new Y.View({
    events: {
        // Call this.toggle() whenever the element with the id
        // "toggle-button" is clicked.
        '#toggle-button': {click: 'toggle'},

        // Call this.hoverOn() when the mouse moves over any element
        // with the "hoverable" class, and this.hoverOff() when the
        // mouse moves out of any element with the "hoverable" class.
        '.hoverable': {
            mouseover: 'hoverOn',
            mouseout : 'hoverOff'
        }
    }

How this template gets used is entirely up to you and your custom render() method.

Default: ''

Attributes

container

HTMLElement | Node | String

Inherited from View: app/js/view.js:376

Container node into which this view's content will be rendered.

The container node serves as the host for all DOM events attached by the view. Delegation is used to handle events on children of the container, allowing the container's contents to be re-rendered at any time without losing event subscriptions.

The default container is a <div> Node, but you can override this in a subclass, or by passing in a custom container config value at instantiation time. If you override the default container in a subclass using ATTRS, you must use the valueFn property. The view's constructor will ignore any assignments using value.

When container is overridden by a subclass or passed as a config option at instantiation time, you can provide it as a selector string, a DOM element, a Y.Node instance, or (if you are subclassing and modifying the attribute), a valueFn function that returns a Y.Node instance. The value will be converted into a Y.Node instance if it isn't one already.

The container is not added to the page automatically. This allows you to have full control over how and when your view is actually rendered to the page.

Default: Y.Node.create(this.containerTemplate)

Fires event containerChange

Fires when the value for the configuration attribute container is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

Parameters:

  • e EventFacade
    An Event Facade object with the following attribute-specific properties added:
    • prevVal Any
      The value of the attribute, prior to it being set.
    • newVal Any
      The value the attribute is to be set to.
    • attrName String
      The name of the attribute being set.
    • subAttrName String
      If setting a property within the attribute's value, the name of the sub-attribute property being set.

destroyed

Boolean readonly

Flag indicating whether or not this object has been through the destroy lifecycle phase.

Default: false

Fires event destroyedChange

Fires when the value for the configuration attribute destroyed is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

Parameters:

  • e EventFacade
    An Event Facade object with the following attribute-specific properties added:
    • prevVal Any
      The value of the attribute, prior to it being set.
    • newVal Any
      The value the attribute is to be set to.
    • attrName String
      The name of the attribute being set.
    • subAttrName String
      If setting a property within the attribute's value, the name of the sub-attribute property being set.

initialized

Boolean readonly

Flag indicating whether or not this object has been through the init lifecycle phase.

Default: false

Fires event initializedChange

Fires when the value for the configuration attribute initialized is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

Parameters:

  • e EventFacade
    An Event Facade object with the following attribute-specific properties added:
    • prevVal Any
      The value of the attribute, prior to it being set.
    • newVal Any
      The value the attribute is to be set to.
    • attrName String
      The name of the attribute being set.
    • subAttrName String
      If setting a property within the attribute's value, the name of the sub-attribute property being set.

Events

destroy

Lifecycle event for the destroy phase, fired prior to destruction. Invoking the preventDefault method on the event object provided to subscribers will prevent destruction from proceeding.

Subscribers to the "after" moment of this event, will be notified after destruction is complete (and as a result cannot prevent destruction).

Event Payload:

init

Lifecycle event for the init phase, fired prior to initialization. Invoking the preventDefault() method on the event object provided to subscribers will prevent initialization from occuring.

Subscribers to the "after" momemt of this event, will be notified after initialization of the object is complete (and therefore cannot prevent initialization).

Event Payload:

  • e EventFacade

    Event object, with a cfg property which refers to the configuration object passed to the constructor.
