Attributes
Methods
_addAttrs
-
cfgs
-
values
-
lazy
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
ObjectAn object with attribute name/configuration pairs.
-
values
ObjectAn 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
BooleanWhether 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]
Finishes initializing an attribute which has been lazily added.
_addOutOfOrder
-
name
-
cfg
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: ...
}
});
_afterContainerChange
()
protected
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.
_aggregateAttrs
-
allAttrs
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
ArrayAn array of ATTRS definitions across classes in the hierarchy (subclass first, Base last)
Returns:
The aggregate set of ATTRS definitions for the instance
_attachBlockEvents
()
protected
Attaches block events.
_attachEvents
()
protected
Attaches editor events.
_attachKeyEvents
()
protected
Attaches keyboard events.
_attachQueueEvents
()
protected
Attaches queue events.
_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
_blockOnSelectionChange
-
e
Event handler for the selection change
event
Creates a default block
if none exists for the current selection
Parameters:
_clearCommandQueue
()
protected
Clears the command queue
_cloneDefaultValue
-
cfg
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:
-
cfg
Object
_createLink
-
options
Implementation for the createLink
command
Wraps the currently selected range in an anchor <a>
tag
_defAttrChangeFn
-
e
-
eventFastPath
Default function for attribute change events.
Parameters:
-
e
EventFacadeThe event object for attribute change events.
-
eventFastPath
BooleanWhether or not we're using this as a fast path in the case of no listeners or not
_defInitFn
-
e
Default init event handler
Parameters:
-
e
EventFacadeEvent object, with a cfg property which refers to the configuration object passed to the constructor.
_delete
-
[direction=back]
Handles backspace and delete because webkit is an idiot and will copy
computed styles like line-height
, color
and font-size
when merging
blocks of different types.
For example given the following HTML:
<h1>foo</h1>
<p>bar</p>
Hitting backspace with the cursor at the beginning of the <p>
element will
create a <span>
in the <h1>
after the text foo
with the computed styles
of the <p>
element. The brilliant result is:
<h1>foo<span style="line-height: 1.2; font-size:12px; color:xxx;">bar</span></h1>
Its so stupid and IE/Firefox do not behave this way.
Related, when deleting across blocks with different text-alignment
,
Firefox will copy text-alignment
from the later block, which is opposite
of what the other browsers do.
This method normalizes the behavior when deleting across blocks to not copy styles. The result from the previous example is now:
<h1>foobar</h1>
Parameters:
-
[direction=back]
String optionalforward
for a forward delete,back
for a backspace
_destroyContainer
()
protected

addAttr
-
name
-
config
-
lazy
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
StringThe name of the attribute.
-
config
ObjectAn 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:
A reference to the host object.
addAttrs
-
cfgs
-
values
-
lazy
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
ObjectAn object with attribute name/configuration pairs.
-
values
ObjectAn 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
BooleanWhether 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:
A reference to the host object.
addTarget
-
o
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:
-
o
EventTargetthe target to add
after
-
type
-
fn
-
[context]
-
[arg*]

Parameters:
Returns:
A subscription handle capable of detaching the subscription
attachEvents
-
[events]
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:
-
[events]
Object optionalHash of events to attach. See the docs for the
events
attribute for details on the format. If not specified, this view'sevents
property will be used.
attrAdded
-
name
Checks if the given attribute has been added to the host
Parameters:
-
name
StringThe name of the attribute to check.
Returns:
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
blur
()
chainable
Removes focus from this editor.
bubble
-
evt
Propagate an event. Requires the event-custom-complex module.
Parameters:
-
evt
CustomEventthe custom event to propagate
Returns:
the aggregated return value from Event.Custom.fire
command
-
name
-
[args]
Executes a given editor command.
By default, the only supported commands are:
- insertHTML
- insertText
See individual editor extensions for additionally supported commands
Parameters:
Returns:
Value of the specified command.
create
-
[container]
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 optionalSelector string,
Y.Node
instance, or DOM element to use at the container node.
Returns:
Node instance of the created container node.
destroy
-
[options]
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.
detach
-
type
-
fn
-
context
Detach one or more listeners the from the specified event
Parameters:
-
type
String | ObjectEither 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
FunctionThe subscribed function to unsubscribe, if not supplied, all subscribers will be removed.
-
context
ObjectThe 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:
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
StringThe type, or name of the event
detachEvents
()
chainable
Detaches DOM events that have previously been attached to the container by
attachEvents()
.
fire
-
type
-
arguments
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 | ObjectThe 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:
True if the whole lifecycle of the event went through, false if at any point the event propagation was halted.
focus
()
chainable
Focuses this editor.
get
-
name
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
StringThe 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:
The value of the attribute
getAttrs
-
attrs
Gets multiple attribute values.
Parameters:
-
attrs
Array | booleanOptional. 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:
An object with attribute name/value pairs.
getEvent
-
type
-
prefixed
Returns the custom event of the provided type has been created, a falsy value otherwise
Parameters:
Returns:
the custom event or null
getTargets
()
Returns an array of bubble targets for this object.
Returns:
EventTarget[]
init
-
cfg

Parameters:
-
cfg
ObjectObject with configuration property name/value pairs
Returns:
A reference to this object
isLink
()
Boolean
Returns whether or not the current range is entirely in an anchor element
Returns:
true
if the range is contained in an anchor element,
false
otherwise
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.
on
-
type
-
fn
-
[context]
-
[arg*]
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:
Returns:
A subscription handle capable of detaching that subscription

parseType
-
type
-
[pre=this._yuievt.config.prefix]

Properties
_allowAdHocAttrs
Boolean
protected
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
_commandQueue
Object
Hash of commands queued for execution on the next keypress.
Workaround for webkit bug where it wont place a caret in an empty node or between nodes.
blockCommands
Object
Hash of block commands supported by this editor.
Names should correspond with valid execCommand()
command names. Values
are properties in the following format:
Sub-properties:
commands
Object
Hash of commands supported by this editor.
Names should correspond with valid execCommand()
command names. Values
are properties in the following format:
Sub-properties:
deleteCommands
Object
Hash of delete commands supported by this editor.
Names should correspond with valid execCommand()
command names. Values
are properties in the following format:
Sub-properties:
events
Object
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'
}
}
});
ignoreKeyCodes
Object
Hash of keyCode values that should be ignored when processing keyboard events.
This is used to avoid double-handling of modifier keys, since other event properties are used to detect whether modifier keys are pressed.
linkCommands
Object
Hash of link commands supported by this editor.
Names should correspond with valid execCommand()
command names. Values
are properties in the following format:
Sub-properties:
selection
Selection
Y.Selection
instance representing the current document selection.
The selection object's state always reflects the current selection, so it will update when the selection changes. If you need to retain the state of a past selection, hold onto a Range instance representing that selection.
Also, beware: this selection object reflects the current selection in the entire browser document, not just within this editor.
styleCommands
Object
Hash of style commands supported by this editor.
Names should correspond with valid execCommand()
command names. Values
are properties in the following format:
Sub-properties:
template
Mixed
Template for this view's contents.
This is a convenience property that has no default behavior of its own.
It's only provided as a convention to allow you to store whatever you
consider to be a template, whether that's an HTML string, a Y.Node
instance, a Mustache template, or anything else your little heart
desires.
How this template gets used is entirely up to you and your custom
render()
method.
Default: ''
Attributes
Function for formatting editor html
One day allow custom formatting. Today is not that day.
Fires event Change
Fires when the value for the configuration attribute `` 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
EventFacadeAn Event Facade object with the following attribute-specific properties added:
container
HTMLElement | Node | String
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

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.

attribute's value has changed.
Parameters:
-
e
EventFacadeAn Event Facade object with the following attribute-specific properties added:
outputName
String
Form field name to use for the hidden <textarea>
that contains the raw
output of the editor in the configured output format. This name will
only be used if the output node doesn't already have a name when the
editor is rendered.
You may need to customize this if you plan to use the editor in a form that will be submitted to a server.
Default: 'editor'
Fires event outputNameChange
Fires when the value for the configuration attribute outputName
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

attribute's value has changed.
Parameters:
-
e
EventFacadeAn Event Facade object with the following attribute-specific properties added:
Events
blur
Fired after this editor loses focus.
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:
-
e
EventFacadeEvent object
focus
Fired after this editor receives focus.
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
EventFacadeEvent object, with a cfg property which refers to the configuration object passed to the constructor.
render
Fired after this editor is rendered.
selectionChange
Fired when this editor's selection changes.
