  • inherited

    capture()

  • clone( [ includeChildren ], [ cloneId ] ) → node

    Clones this node.

    Note: Values set by {setCustomData} will not be available in the clone.

    Parameters

    true if the object is equal.

  • inherited

    fire( eventName, [ data ], [ editor ] ) → Boolean | Object

    Fires an specific event in the object. All registered listeners are called at this point.

    someObject.on( 'someEvent', function() { ... } );
    someObject.on( 'someEvent', function() { ... } );
    someObject.fire( 'someEvent' );             // Both listeners are called.

    someObject.on( 'someEvent', function() { ... } );
    someObject.fire( 'someEvent' );         // Above listener called.
    someObject.fireOnce( 'someEvent' );     // Above listener called.

  • getAddress( [ normalized ] ) → Array

    Retrieves a uniquely identifiable tree address for this node. The tree address returned is an array of integers, with each integer indicating a child index of a DOM node, starting from document.documentElement.

    For example, assuming <body> is the second child of <html> (<head> being the first), and we would like to address the third child under the fourth child of <body>, the tree address returned would be: [1, 3, 2].

    The tree address cannot be used for finding back the DOM tree node once the DOM tree structure has been modified.

    Parameters

    [ normalized ] : Boolean

    See getIndex.

    Defaults to false

    Returns

    Array

    The address.

    // If node == <b>
    ascendant = node.getAscendant( 'div' );             // ascendant == <div id="inner">

  • since 3.5.0

    isReadOnly( [ checkOnlyAttributes ] ) → Boolean

    Checks if this node is read-only (should not be changed).

    // For the following HTML:
    // <b>foo</b><div contenteditable="false"><i>bar</i></div>
    
    elB.isReadOnly(); // -> false
    foo.isReadOnly(); // -> false
    elDiv.isReadOnly(); // -> true
    elI.isReadOnly(); // -> true
    

    This method works in two modes depending on browser support for the element.isContentEditable property and the value of the checkOnlyAttributes parameter. The element.isContentEditable check is faster, but it is known to malfunction in hidden or detached nodes. Additionally, when processing some detached DOM tree you may want to imitate that this happens inside an editable container (like it would happen inside the CKEDITOR.editable). To do so, you can temporarily attach this tree to an element with the data-cke-editable attribute and use the checkOnlyAttributes mode.

    Parameters

    [ checkOnlyAttributes ] : Boolean

    If true, only attributes will be checked, native methods will not be used. This parameter needs to be true to check hidden or detached elements. Introduced in 4.5.0.

    Defaults to false

    Returns

    Boolean
  • ltrim()

  • move( target, toStart )

    Parameters

    target : Object
    toStart : Object
  • inherited

    on( eventName, listenerFunction, [ scopeObj ], [ listenerData ], [ priority ] ) → Object

    Registers a listener to a specific event in the current object.

    someObject.on( 'someEvent', function() {
        alert( this == someObject );        // true
    } );
    
    someObject.on( 'someEvent', function() {
        alert( this == anotherObject );     // true
    }, anotherObject );
    
    someObject.on( 'someEvent', function( event ) {
        alert( event.listenerData );        // 'Example'
    }, null, 'Example' );
    
    someObject.on( 'someEvent', function() { ... } );                       // 2nd called
    someObject.on( 'someEvent', function() { ... }, null, null, 100 );      // 3rd called
    someObject.on( 'someEvent', function() { ... }, null, null, 1 );        // 1st called
    

    Note: CKEditor's event system has a limitation that one function cannot be used as a listener for the same event more than once. Hence, to reuse it with multiple listeners, it should be wrapped into additional wrapper function:

    function listener( evt ) { ... };
    
    someObject.on( 'someEvent', function() {
        listener();
    } );
    
    someObject.on( 'someEvent', function( evt ) {
        listener( evt );
    } );
    

    Parameters

    eventName : String

    The event name to which listen.

    listenerFunction : Function

    The function listening to the event. A single CKEDITOR.eventInfo object instanced is passed to this function containing all the event data.

    [ scopeObj ] : Object

    The object used to scope the listener call (the this object). If omitted, the current object is used.

    [ listenerData ] : Object

    Data to be sent as the CKEDITOR.eventInfo.listenerData when calling the listener.

    [ priority ] : Number

    The listener priority. Lower priority listeners are called first. Listeners with the same priority value are called in registration order.

    Defaults to 10

    Returns

    Object

    An object containing the removeListener function, which can be used to remove the listener at any time.

  • inherited

    once()

    remove( [ preserveChildren ] ) → node

    Parameters

    key : String

    Returns

    Object

    removeListener( eventName, listenerFunction )

    Unregisters a listener function from being called at the specified event. No errors are thrown if the listener has not been registered previously.

    someObject.on( 'someEvent', myListener );
    someObject.fire( 'someEvent' );                 // myListener called.
    someObject.removeListener( 'someEvent', myListener );
    someObject.fire( 'someEvent' );                 // myListener not called.

    Parameters

    nodeToReplace : Object

    setCustomData( key, value ) → domObject

    Sets a data slot value for this object. These values are shared by all instances pointing to that same DOM object.

    Note: The created data slot is only guaranteed to be available on this unique DOM node, thus any wish to continue access to it from other element clones (either created by clone node or from innerHtml) will fail. For such usage please use CKEDITOR.dom.element.setAttribute instead.

    Note: This method does not work on text nodes prior to Internet Explorer 9.

    var element = new CKEDITOR.dom.element( 'span' );
    element.setCustomData( 'hasCustomData', true );
    

    Parameters

    key : String

    A key used to identify the data slot.

    value : Object

    The value to set to the data slot.

    Returns

    domObject
