Methods
-
Creates a domObject class instance.
Parameters
nativeDomObject : ObjectA native DOM object.
Returns
domObject

Returns
elementThe target element.
-
Register event handler under the capturing stage on supported target.
-
Removes any data stored in this object. To avoid memory leaks we must assure that there are no references left after the object is no longer needed.
-
Clones this node.
Note: Values set by {setCustomData} will not be available in the clone.
Parameters
[ includeChildren ] : BooleanIf
truethen all node's children will be cloned recursively.Defaults to
false[ cloneId ] : BooleanWhether ID attributes should be cloned, too.
Defaults to
false
Returns
nodeClone of this node.
-
Predefine some intrinsic properties on a specific event name.
Parameters

Determines whether the specified object is equal to the current object.
var doc = new CKEDITOR.dom.document( document ); alert( doc.equals( CKEDITOR.document ) ); // true alert( doc == CKEDITOR.document ); // falseParameters
object : ObjectThe object to compare with the current object.
Returns
Booleantrueif the object is equal.
-
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( event ) { alert( event.data ); // 'Example' } ); someObject.fire( 'someEvent', 'Example' );Parameters

[ editor ] : editorThe editor instance to send as the CKEDITOR.eventInfo.editor when calling the listener.
Returns
Boolean | ObjectA boolean indicating that the event is to be canceled, or data returned by one of the listeners.
inherited
fireOnce( eventName, [ data ], [ editor ] ) → Boolean | ObjectCKEDITOR.dom.comment#fireOnceFires an specific event in the object, releasing all listeners registered to that event. The same listeners are not called again on successive calls of it or of fire.
someObject.on( 'someEvent', function() { ... } ); someObject.fire( 'someEvent' ); // Above listener called. someObject.fireOnce( 'someEvent' ); // Above listener called. someObject.fire( 'someEvent' ); // No listeners called.Parameters

-
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.

false
Returns
ArrayThe address.

-
Inserts this element after a node.
var em = new CKEDITOR.dom.element( 'em' ); var strong = new CKEDITOR.dom.element( 'strong' ); strong.insertAfter( em ); // Result: '<em></em><strong></strong>'Parameters
node : nodeThe node that will precede this element.
Returns
nodeThe node preceding this one after insertion.
-
Inserts this element before a node.
var em = new CKEDITOR.dom.element( 'em' ); var strong = new CKEDITOR.dom.element( 'strong' ); strong.insertBefore( em ); // result: '<strong></strong><em></em>'Parameters
node : nodeThe node that will succeed this element.
Returns
nodeThe node being inserted.
-
Inserts a node before this node.
var em = new CKEDITOR.dom.element( 'em' ); var strong = new CKEDITOR.dom.element( 'strong' ); strong.insertBeforeMe( em ); // result: '<em></em><strong></strong>'Parameters
node : nodeThe node that will preceed this element.
Returns
nodeThe node being inserted.
-
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(); // -> trueThis method works in two modes depending on browser support for the
element.isContentEditableproperty and the value of thecheckOnlyAttributesparameter. Theelement.isContentEditablecheck 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 thedata-cke-editableattribute and use thecheckOnlyAttributesmode.Parameters
[ checkOnlyAttributes ] : BooleanIf
true, only attributes will be checked, native methods will not be used. This parameter needs to betrueto check hidden or detached elements. Introduced in 4.5.0.Defaults to
false
Returns
Boolean

on( eventName, listenerFunction, [ scopeObj ], [ listenerData ], [ priority ] ) → ObjectCKEDITOR.dom.comment#onRegisters 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 calledNote: 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 : StringThe event name to which listen.
listenerFunction : FunctionThe function listening to the event. A single CKEDITOR.eventInfo object instanced is passed to this function containing all the event data.
[ scopeObj ] : ObjectThe object used to scope the listener call (the
thisobject). If omitted, the current object is used.[ listenerData ] : ObjectData to be sent as the CKEDITOR.eventInfo.listenerData when calling the listener.
[ priority ] : NumberThe listener priority. Lower priority listeners are called first. Listeners with the same priority value are called in registration order.
Defaults to
10
Returns
ObjectAn object containing the
removeListenerfunction, which can be used to remove the listener at any time.
-
Similiar with on but the listener will be called only once upon the next event firing.
-
Removes this node from the document DOM.
var element = CKEDITOR.document.getById( 'MyElement' ); element.remove();Parameters
[ preserveChildren ] : BooleanIndicates that the children elements must remain in the document, removing only the outer tags.
Defaults to
false
Returns
nodethis
-
Removes any listener set on this object.
To avoid memory leaks we must assure that there are no references left after the object is no longer needed.
-
Removes the value in the data slot under the given
key.Parameters
key : String
Returns
ObjectRemoved value or
nullif not found.
-
Unregisters a listener function from being called at the specified event. No errors are thrown if the listener has not been registered previously.
var myListener = function() { ... }; someObject.on( 'someEvent', myListener ); someObject.fire( 'someEvent' ); // myListener called. someObject.removeListener( 'someEvent', myListener ); someObject.fire( 'someEvent' ); // myListener not called.Parameters
eventName : StringThe event name.
listenerFunction : FunctionThe listener function to unregister.
-
-
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 : StringA key used to identify the data slot.
value : ObjectThe value to set to the data slot.
Returns
domObjectThis DOM object instance.
