ClassicEditor (editor-classic)

@ckeditor/ckeditor5-editor-classic/src/classiceditor

class

The classic editor implementation. It uses an inline editable and a sticky toolbar, all enclosed in a boxed UI. See the demo.

In order to create a classic editor instance, use the static ClassicEditor.create() method.

Properties

readonly inherited
accessibility : Accessibility

See source
A namespace for the accessibility features of the editor.
readonly inherited
commands : CommandCollection
See source
Commands registered to the editor.

Use the shorthand editor.execute() method to execute commands:
```
// Execute the bold command:
editor.execute( 'bold' );

// Check the state of the bold command:
editor.commands.get( 'bold' ).value;
```
readonly inherited
config : Config<EditorConfig>
See source
Stores all configurations specific to this editor instance.
```
editor.config.get( 'image.toolbar' );
// -> [ 'imageStyle:block', 'imageStyle:side', '|', 'toggleImageCaption', 'imageTextAlternative' ]
```
readonly inherited
conversion : Conversion

See source
Conversion manager through which you can register model-to-view and view-to-model converters.

See the Conversion documentation to learn how to add converters.
readonly inherited
data : DataController

See source
The data controller. Used e.g. for setting and retrieving the editor data.
readonly inherited
editing : EditingController

See source
The editing controller. Controls user input and rendering the content for editing.
readonly inherited
id : string

See source
inherited
isReadOnly : boolean
See source
Defines whether the editor is in the read-only mode.

In read-only mode the editor commands are disabled so it is not possible to modify the document by using them. Also, the editable element(s) become non-editable.

In order to make the editor read-only, you need to call the enableReadOnlyMode method:
```
editor.enableReadOnlyMode( 'feature-id' );
```
- Later, to turn off the read-only mode, call disableReadOnlyMode:
```
editor.disableReadOnlyMode( 'feature-id' );
```
Parameters

value : boolean
readonly inherited
keystrokes : EditingKeystrokeHandler
See source
An instance of the EditingKeystrokeHandler.

It allows setting simple keystrokes:
```
// Execute the bold command on Ctrl+E:
editor.keystrokes.set( 'Ctrl+E', 'bold' );

// Execute your own callback:
editor.keystrokes.set( 'Ctrl+E', ( data, cancel ) => {
	console.log( data.keyCode );

	// Prevent the default (native) action and stop the underlying keydown event
	// so no other editor feature will interfere.
	cancel();
} );
```
Note: Certain typing-oriented keystrokes (like Backspace or Enter) are handled by a low-level mechanism and trying to listen to them via the keystroke handler will not work reliably. To handle these specific keystrokes, see the events fired by the editing view document (editor.editing.view.document).
readonly inherited
locale : Locale

See source
The locale instance.
readonly inherited
model : Model

See source
The editor's model.

The central point of the editor's abstract data model.
readonly inherited
plugins : PluginCollection<Editor>
See source
The plugins loaded and in use by this editor instance.
```
editor.plugins.get( 'ClipboardPipeline' ); // -> An instance of the clipboard pipeline plugin.
```

`builtinPlugins : Array<PluginConstructor<Editor>> | undefined`

See source

An array of plugins built into this editor class.

It is used in CKEditor 5 builds to provide a list of plugins which are later automatically initialized during the editor initialization.

They will be automatically initialized by the editor, unless listed in config.removePlugins and unless config.plugins is passed.

// Build some plugins into the editor class first.
ClassicEditor.builtinPlugins = [ FooPlugin, BarPlugin ];

// Normally, you need to define config.plugins, but since ClassicEditor.builtinPlugins was
// defined, now you can call create() without any configuration.
ClassicEditor
	.create( sourceElement )
	.then( editor => {
		editor.plugins.get( FooPlugin ); // -> An instance of the Foo plugin.
		editor.plugins.get( BarPlugin ); // -> An instance of the Bar plugin.
	} );

ClassicEditor
	.create( sourceElement, {
		// Do not initialize these plugins (note: it is defined by a string):
		removePlugins: [ 'Foo' ]
	} )
	.then( editor => {
		editor.plugins.get( FooPlugin ); // -> Undefined.
		editor.config.get( BarPlugin ); // -> An instance of the Bar plugin.
	} );

ClassicEditor
	.create( sourceElement, {
		// Load only this plugin. It can also be defined by a string if
		// this plugin was built into the editor class.
		plugins: [ FooPlugin ]
	} )
	.then( editor => {
		editor.plugins.get( FooPlugin ); // -> An instance of the Foo plugin.
		editor.config.get( BarPlugin ); // -> Undefined.
	} );

inherited static
`defaultConfig : EditorConfig | undefined`

See source

The default configuration which is built into the editor class.

It is used in CKEditor 5 builds to provide the default configuration options which are later used during the editor initialization.

ClassicEditor.defaultConfig = {
	foo: 1,
	bar: 2
};

ClassicEditor
	.create( sourceElement )
	.then( editor => {
		editor.config.get( 'foo' ); // -> 1
		editor.config.get( 'bar' ); // -> 2
	} );

// The default options can be overridden by the configuration passed to create().
ClassicEditor
	.create( sourceElement, { bar: 3 } )
	.then( editor => {
		editor.config.get( 'foo' ); // -> 1
		editor.config.get( 'bar' ); // -> 3
	} );

Methods

protected
constructor( sourceElementOrData, config )

See source
Creates an instance of the classic editor.

Note: do not use the constructor to create editor instances. Use the static ClassicEditor.create() method instead.

Parameters

sourceElementOrData : string | HTMLElement

The DOM element that will be the source for the created editor or the editor's initial data. For more information see ClassicEditor.create().

config : EditorConfig

The editor configuration.

Defaults to {}
inherited
bind( bindProperties ) → MultiBindChain
See source
Binds observable properties to other objects implementing the Observable interface.

Read more in the dedicated guide covering the topic of property bindings with some additional examples.

Consider two objects: a button and an associated command (both Observable).

A simple property binding could be as follows:
```
button.bind( 'isEnabled' ).to( command, 'isEnabled' );
```
or even shorter:
```
button.bind( 'isEnabled' ).to( command );
```
which works in the following way:
- button.isEnabled instantly equals command.isEnabled,
- whenever command.isEnabled changes, button.isEnabled will immediately reflect its value.
Note: To release the binding, use unbind.

You can also "rename" the property in the binding by specifying the new name in the to() chain:
```
button.bind( 'isEnabled' ).to( command, 'isWorking' );
```
It is possible to bind more than one property at a time to shorten the code:
```
button.bind( 'isEnabled', 'value' ).to( command );
```
which corresponds to:
```
button.bind( 'isEnabled' ).to( command );
button.bind( 'value' ).to( command );
```
The binding can include more than one observable, combining multiple data sources in a custom callback:
```
button.bind( 'isEnabled' ).to( command, 'isEnabled', ui, 'isVisible',
	( isCommandEnabled, isUIVisible ) => isCommandEnabled && isUIVisible );
```
Using a custom callback allows processing the value before passing it to the target property:
```
button.bind( 'isEnabled' ).to( command, 'value', value => value === 'heading1' );
```
It is also possible to bind to the same property in an array of observables. To bind a button to multiple commands (also Observables) so that each and every one of them must be enabled for the button to become enabled, use the following code:
```
button.bind( 'isEnabled' ).toMany( [ commandA, commandB, commandC ], 'isEnabled',
	( isAEnabled, isBEnabled, isCEnabled ) => isAEnabled && isBEnabled && isCEnabled );
```
Parameters

bindProperties : Array<'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'data' | 'focus' | 'id' | 'config' | 'locale' | 't' | 'destroy' | 'execute' | 'plugins' | 'ui' | 'isReadOnly' | 'editing' | 'model' | 'keystrokes' | 'accessibility' | 'commands' | 'conversion' | 'state' | 'enableReadOnlyMode' | 'disableReadOnlyMode' | 'setData' | 'getData' | 'initPlugins' | 'sourceElement' | 'updateSourceElement'>

Observable properties that will be bound to other observable(s).

Returns

MultiBindChain

The bind chain with the to() and toMany() methods.

inherited
decorate( methodName ) → void
See source
Turns the given methods of this object into event-based ones. This means that the new method will fire an event (named after the method) and the original action will be plugged as a listener to that event.

Read more in the dedicated guide covering the topic of decorating methods with some additional examples.

Decorating the method does not change its behavior (it only adds an event), but it allows to modify it later on by listening to the method's event.

For example, to cancel the method execution the event can be stopped:
```
class Foo extends ObservableMixin() {
	constructor() {
		super();
		this.decorate( 'method' );
	}

	method() {
		console.log( 'called!' );
	}
}

const foo = new Foo();
foo.on( 'method', ( evt ) => {
	evt.stop();
}, { priority: 'high' } );

foo.method(); // Nothing is logged.
```
Note: The high priority listener has been used to execute this particular callback before the one which calls the original method (which uses the "normal" priority).

It is also possible to change the returned value:
```
foo.on( 'method', ( evt ) => {
	evt.return = 'Foo!';
} );

foo.method(); // -> 'Foo'
```
Finally, it is possible to access and modify the arguments the method is called with:
```
method( a, b ) {
	console.log( `${ a }, ${ b }`  );
}

// ...

foo.on( 'method', ( evt, args ) => {
	args[ 0 ] = 3;

	console.log( args[ 1 ] ); // -> 2
}, { priority: 'high' } );

foo.method( 1, 2 ); // -> '3, 2'
```
Parameters

methodName : 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'data' | 'focus' | 'id' | 'config' | 'locale' | 't' | 'destroy' | 'execute' | 'plugins' | 'ui' | 'isReadOnly' | 'editing' | 'model' | 'keystrokes' | 'accessibility' | 'commands' | 'conversion' | 'state' | 'enableReadOnlyMode' | 'disableReadOnlyMode' | 'setData' | 'getData' | 'initPlugins' | 'sourceElement' | 'updateSourceElement'

Name of the method to decorate.

Returns

void
inherited
delegate( events ) → EmitterMixinDelegateChain
See source
Delegates selected events to another Emitter. For instance:
```
emitterA.delegate( 'eventX' ).to( emitterB );
emitterA.delegate( 'eventX', 'eventY' ).to( emitterC );
```
then eventX is delegated (fired by) emitterB and emitterC along with data:
```
emitterA.fire( 'eventX', data );
```
and eventY is delegated (fired by) emitterC along with data:
```
emitterA.fire( 'eventY', data );
```
Parameters

events : Array<string>

Event names that will be delegated to another emitter.

Returns

EmitterMixinDelegateChain
destroy() → Promise<unknown>

See source
Destroys the editor instance, releasing all resources used by it.

Updates the original editor element with the data if the updateSourceElementOnDestroy configuration option is set to true.

Returns

Promise<unknown>
inherited
disableReadOnlyMode( lockId ) → void

See source
Removes the read-only lock from the editor with given lock ID.

When no lock is present on the editor anymore, then the isReadOnly property will be set to false.

Parameters

lockId : string | symbol

The lock ID for setting the editor to the read-only state.

Returns

void
inherited
enableReadOnlyMode( lockId ) → void
See source
Turns on the read-only mode in the editor.

Editor can be switched to or out of the read-only mode by many features, under various circumstances. The editor supports locking mechanism for the read-only mode. It enables easy control over the read-only mode when many features wants to turn it on or off at the same time, without conflicting with each other. It guarantees that you will not make the editor editable accidentally (which could lead to errors).

Each read-only mode request is identified by a unique id (also called "lock"). If multiple plugins requested to turn on the read-only mode, then, the editor will become editable only after all these plugins turn the read-only mode off (using the same ids).

Note, that you cannot force the editor to disable the read-only mode if other plugins set it.

After the first enableReadOnlyMode() call, the isReadOnly property will be set to true:
```
editor.isReadOnly; // `false`.
editor.enableReadOnlyMode( 'my-feature-id' );
editor.isReadOnly; // `true`.
```
You can turn off the read-only mode ("clear the lock") using the disableReadOnlyMode() method:
```
editor.enableReadOnlyMode( 'my-feature-id' );
// ...
editor.disableReadOnlyMode( 'my-feature-id' );
editor.isReadOnly; // `false`.
```
All "locks" need to be removed to enable editing:
```
editor.enableReadOnlyMode( 'my-feature-id' );
editor.enableReadOnlyMode( 'my-other-feature-id' );
// ...
editor.disableReadOnlyMode( 'my-feature-id' );
editor.isReadOnly; // `true`.
editor.disableReadOnlyMode( 'my-other-feature-id' );
editor.isReadOnly; // `false`.
```
Parameters

lockId : string | symbol

A unique ID for setting the editor to the read-only state.

Returns

void
inherited
execute( commandName, commandParams ) → ReturnType<CommandsMap[ TName ][ 'execute' ]>
See source
Executes the specified command with given parameters.

Shorthand for:
```
editor.commands.get( commandName ).execute( ... );
```
Type parameters

TName : extends string

Parameters

commandName : TName

The name of the command to execute.

commandParams : Parameters<CommandsMap[ TName ][ 'execute' ]>

Command parameters.

Returns

ReturnType<CommandsMap[ TName ][ 'execute' ]>

The value returned by the commands.execute().
inherited
fire( eventOrInfo, args ) → GetEventInfo<TEvent>[ 'return' ]

See source
Fires an event, executing all callbacks registered for it.

The first parameter passed to callbacks is an EventInfo object, followed by the optional args provided in the fire() method call.

Type parameters

TEvent : extends BaseEvent

The type describing the event. See BaseEvent.

Parameters

eventOrInfo : GetNameOrEventInfo<TEvent>

The name of the event or EventInfo object if event is delegated.

args : TEvent[ 'args' ]

Additional arguments to be passed to the callbacks.

Returns

GetEventInfo<TEvent>[ 'return' ]

By default the method returns undefined. However, the return value can be changed by listeners through modification of the evt.return's property (the event info is the first param of every callback).
inherited
focus() → void

See source
Focuses the editor.

Note To explicitly focus the editing area of the editor, use the editor.editing.view.focus() method of the editing view.

Check out the Focus in the editor UI section of the Deep dive into focus tracking guide to learn more.

Returns

void
inherited
getData( [ options ] = { [options.rootName], [options.trim], options[key: string] } ) → string
See source
Gets the data from the editor.
```
editor.getData(); // -> 'This is editor!'
```
If your editor implementation uses multiple roots, you should pass root name as one of the options:
```
editor.getData( { rootName: 'header' } ); // -> 'Content for header part.'
```
By default, the editor outputs HTML. This can be controlled by injecting a different data processor. See the Markdown output guide for more details.

A warning is logged when you try to retrieve data for a detached root, as most probably this is a mistake. A detached root should be treated like it is removed, and you should not save its data. Note, that the detached root data is always an empty string.

Parameters

[ options ] : object

Additional configuration for the retrieved data. Editor features may introduce more configuration options that can be set through this parameter.

Properties

[ options.rootName ] : string

Root name. Defaults to 'main'.

[ options.trim ] : 'none' | 'empty'

Whether returned data should be trimmed. This option is set to 'empty' by default, which means that whenever editor content is considered empty, an empty string is returned. To turn off trimming use 'none'. In such cases exact content will be returned (for example ' ' for an empty editor).

options[key: string] : unknown

Returns

string

Output data.
inherited
initPlugins() → Promise<LoadedPlugins>

See source
Loads and initializes plugins specified in the configuration.

Returns

Promise<LoadedPlugins>

A promise which resolves once the initialization is completed, providing an array of loaded plugins.
inherited
listenTo( emitter, event, callback, [ options ] ) → void
See source
Registers a callback function to be executed when an event is fired in a specific (emitter) object.

Events can be grouped in namespaces using :. When namespaced event is fired, it additionally fires all callbacks for that namespace.
```
// myEmitter.on( ... ) is a shorthand for myEmitter.listenTo( myEmitter, ... ).
myEmitter.on( 'myGroup', genericCallback );
myEmitter.on( 'myGroup:myEvent', specificCallback );

// genericCallback is fired.
myEmitter.fire( 'myGroup' );
// both genericCallback and specificCallback are fired.
myEmitter.fire( 'myGroup:myEvent' );
// genericCallback is fired even though there are no callbacks for "foo".
myEmitter.fire( 'myGroup:foo' );
```
An event callback can stop the event and set the return value of the fire method.

Type parameters

TEvent : extends BaseEvent

The type describing the event. See BaseEvent.

Parameters

emitter : Emitter

The object that fires the event.

event : TEvent[ 'name' ]

The name of the event.

callback : GetCallback<TEvent>

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

void
inherited
off( event, callback ) → void

See source
Stops executing the callback on the given event. Shorthand for this.stopListening( this, event, callback ).

Parameters

event : string

The name of the event.

callback : Function

The function to stop being called.

Returns

void
inherited
on( event, callback, [ options ] ) → void

See source
Registers a callback function to be executed when an event is fired.

Shorthand for this.listenTo( this, event, callback, options ) (it makes the emitter listen on itself).

Type parameters

TEvent : extends BaseEvent

The type descibing the event. See BaseEvent.

Parameters

event : TEvent[ 'name' ]

The name of the event.

callback : GetCallback<TEvent>

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

void
inherited
once( event, callback, [ options ] ) → void

See source
Registers a callback function to be executed on the next time the event is fired only. This is similar to calling on followed by off in the callback.

Type parameters

TEvent : extends BaseEvent

The type descibing the event. See BaseEvent.

Parameters

event : TEvent[ 'name' ]

The name of the event.

callback : GetCallback<TEvent>

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

void
inherited
set( values ) → void
See source
Creates and sets the value of an observable properties of this object. Such a property becomes a part of the state and is observable.

It accepts a single object literal containing key/value pairs with properties to be set.

This method throws the observable-set-cannot-override error if the observable instance already has a property with the given property name. This prevents from mistakenly overriding existing properties and methods, but means that foo.set( 'bar', 1 ) may be slightly slower than foo.bar = 1.

In TypeScript, those properties should be declared in class using declare keyword. In example:
```
public declare myProp1: number;
public declare myProp2: string;

constructor() {
	this.set( {
		'myProp1: 2,
		'myProp2: 'foo'
	} );
}
```
Parameters

values : object

An object with name=>value pairs.

Returns

void
inherited
set( name, value ) → void
See source
Creates and sets the value of an observable property of this object. Such a property becomes a part of the state and is observable.

This method throws the observable-set-cannot-override error if the observable instance already has a property with the given property name. This prevents from mistakenly overriding existing properties and methods, but means that foo.set( 'bar', 1 ) may be slightly slower than foo.bar = 1.

In TypeScript, those properties should be declared in class using declare keyword. In example:
```
public declare myProp: number;

constructor() {
	this.set( 'myProp', 2 );
}
```
Type parameters

K

Parameters

name : K

The property's name.

value : ClassicEditor[ K ]

The property's value.

Returns

void
inherited
setData( data ) → void
See source
Sets the data in the editor.
```
editor.setData( 'This is editor!' );
```
If your editor implementation uses multiple roots, you should pass an object with keys corresponding to the editor root names and values equal to the data that should be set in each root:
```
editor.setData( {
 header: 'Content for header part.',
 content: 'Content for main part.',
 footer: 'Content for footer part.'
} );
```
By default the editor accepts HTML. This can be controlled by injecting a different data processor. See the Markdown output guide for more details.

Parameters

data : string | Record<string, string>

Input data.

Returns

void
inherited

inherited
updateSourceElement( [ data ] ) → void

See source
Updates the editor source element's content with the data if the updateSourceElementOnDestroy configuration option is set to true.

Parameters

[ data ] : string

Data that the editor source element should be updated with.

Returns

void

Static methods

static
create( sourceElementOrData, config ) → Promise<ClassicEditor>
See source
Creates a new classic editor instance.

There are three ways how the editor can be initialized.

Replacing a DOM element (and loading data from it)

You can initialize the editor using an existing DOM element:
```
ClassicEditor
	.create( document.querySelector( '#editor' ) )
	.then( editor => {
		console.log( 'Editor was initialized', editor );
	} )
	.catch( err => {
		console.error( err.stack );
	} );
```
The element's content will be used as the editor data and the element will be replaced by the editor UI.

Creating a detached editor

Alternatively, you can initialize the editor by passing the initial data directly as a string. In this case, the editor will render an element that must be inserted into the DOM:
```
ClassicEditor
	.create( 'Hello world!' )
	.then( editor => {
		console.log( 'Editor was initialized', editor );

		// Initial data was provided so the editor UI element needs to be added manually to the DOM.
		document.body.appendChild( editor.ui.element );
	} )
	.catch( err => {
		console.error( err.stack );
	} );
```
This lets you dynamically append the editor to your web page whenever it is convenient for you. You may use this method if your web page content is generated on the client side and the DOM structure is not ready at the moment when you initialize the editor.

Replacing a DOM element (and data provided in config.initialData)

You can also mix these two ways by providing a DOM element to be used and passing the initial data through the configuration:
```
ClassicEditor
	.create( document.querySelector( '#editor' ), {
		initialData: '<h2>Initial data</h2>Foo bar.'
	} )
	.then( editor => {
		console.log( 'Editor was initialized', editor );
	} )
	.catch( err => {
		console.error( err.stack );
	} );
```
This method can be used to initialize the editor on an existing element with the specified content in case if your integration makes it difficult to set the content of the source element.

Note that an error will be thrown if you pass the initial data both as the first parameter and also in the configuration.

Configuring the editor

See the editor configuration documentation to learn more about customizing plugins, toolbar and more.

Parameters

sourceElementOrData : string | HTMLElement

The DOM element that will be the source for the created editor or the editor's initial data.

If a DOM element is passed, its content will be automatically loaded to the editor upon initialization and the editor element will replace the passed element in the DOM (the original one will be hidden and the editor will be injected next to it).

If the updateSourceElementOnDestroy option is set to true, the editor data will be set back to the original element once the editor is destroyed and when a form, in which this element is contained, is submitted (if the original element is a <textarea>). This ensures seamless integration with native web forms.

If the initial data is passed, a detached editor will be created. In this case you need to insert it into the DOM manually. It is available under the editor.ui.element property.

config : EditorConfig

The editor configuration.

Defaults to {}

Returns

Promise<ClassicEditor>

A promise resolved once the editor is ready. The promise resolves with the created editor instance.

Events

inherited
change:isReadOnly( eventInfo, name, value, oldValue )

See source
Fired when the isReadOnly property changed value.

Parameters

eventInfo : EventInfo

An object containing information about the fired event.

name : string

Name of the changed property (isReadOnly).

value : boolean

New value of the isReadOnly property with given key or null, if operation should remove property.

oldValue : boolean

Old value of the isReadOnly property with given key or null, if property was not set before.
inherited
change:state( eventInfo, name, value, oldValue )

See source
Fired when the state property changed value.

Parameters

eventInfo : EventInfo

An object containing information about the fired event.

name : string

Name of the changed property (state).

value : 'ready' | 'initializing' | 'destroyed'

New value of the state property with given key or null, if operation should remove property.

oldValue : 'ready' | 'initializing' | 'destroyed'

Old value of the state property with given key or null, if property was not set before.
inherited
change:{property}( eventInfo, name, value, oldValue )
See source
Fired when a property changed value.
```
observable.set( 'prop', 1 );

observable.on<ObservableChangeEvent<number>>( 'change:prop', ( evt, propertyName, newValue, oldValue ) => {
	console.log( `${ propertyName } has changed from ${ oldValue } to ${ newValue }` );
} );

observable.prop = 2; // -> 'prop has changed from 1 to 2'
```
Parameters

eventInfo : EventInfo

An object containing information about the fired event.

name : string

The property name.

value : TValue

The new property value.

oldValue : TValue

The previous property value.
inherited
destroy( eventInfo )

See source
Fired when this editor instance is destroyed. The editor at this point is not usable and this event should be used to perform the clean-up in any plugin.

See also the editor.state property.

Parameters

eventInfo : EventInfo

An object containing information about the fired event.
inherited
ready( eventInfo )

See source
Fired when the data and all additional editor components are ready.

Note: This event is most useful for plugin developers. When integrating the editor with your website or application, you do not have to listen to editor#ready because when the promise returned by the static Editor.create() event is resolved, the editor is already ready. In fact, since the first moment when the editor instance is available to you is inside then()'s callback, you cannot even add a listener to the editor#ready event.

See also the editor.state property.

Parameters

eventInfo : EventInfo

An object containing information about the fired event.
inherited
set:isReadOnly( eventInfo, name, value, oldValue )

See source
Fired when the isReadOnly property is going to be set but is not set yet (before the change event is fired).

Parameters

eventInfo : EventInfo

An object containing information about the fired event.

name : string

Name of the changed property (isReadOnly).

value : boolean

New value of the isReadOnly property with given key or null, if operation should remove property.

oldValue : boolean

Old value of the isReadOnly property with given key or null, if property was not set before.
inherited
set:state( eventInfo, name, value, oldValue )

See source
Fired when the state property is going to be set but is not set yet (before the change event is fired).

Parameters

eventInfo : EventInfo

An object containing information about the fired event.

name : string

Name of the changed property (state).

value : 'ready' | 'initializing' | 'destroyed'

New value of the state property with given key or null, if operation should remove property.

oldValue : 'ready' | 'initializing' | 'destroyed'

Old value of the state property with given key or null, if property was not set before.
inherited
set:{property}( eventInfo, name, value, oldValue )
See source
Fired when a property value is going to be set but is not set yet (before the change event is fired).

You can control the final value of the property by using the event's return property.
```
observable.set( 'prop', 1 );

observable.on<ObservableSetEvent<number>>( 'set:prop', ( evt, propertyName, newValue, oldValue ) => {
	console.log( `Value is going to be changed from ${ oldValue } to ${ newValue }` );
	console.log( `Current property value is ${ observable[ propertyName ] }` );

	// Let's override the value.
	evt.return = 3;
} );

observable.on<ObservableChangeEvent<number>>( 'change:prop', ( evt, propertyName, newValue, oldValue ) => {
	console.log( `Value has changed from ${ oldValue } to ${ newValue }` );
} );

observable.prop = 2; // -> 'Value is going to be changed from 1 to 2'
 // -> 'Current property value is 1'
 // -> 'Value has changed from 1 to 3'
```
Note: The event is fired even when the new value is the same as the old value.

Parameters

eventInfo : EventInfo

An object containing information about the fired event.

name : string

The property name.

value : TValue

The new property value.

oldValue : TValue

The previous property value.
