- The private object. 
 
-  Gets an ID that can be used to identify this DOM object in the running session. Note: This method does not work on text nodes prior to Internet Explorer 9. Returns- Number
- A unique ID. 
 
-  
-  Checks if there is any listener registered to a given event. var myListener = function() { ... }; someObject.on( 'someEvent', myListener ); alert( someObject.hasListeners( 'someEvent' ) ); // true alert( someObject.hasListeners( 'noEvent' ) ); // falseParameters- eventName : String
- The event name. 
 Returns- Boolean
 
-  
-  
-  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 : node
- The node that will precede this element. 
 Returns- node
- The 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 : node
- The node that will succeed this element. 
 Returns- node

-  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 : node
- The node that will preceed this element. 
 Returns- node

-  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 ] : Boolean
- If - true, only attributes will be checked, native methods will not be used. This parameter needs to be- trueto check hidden or detached elements. Introduced in 4.5.0.- Defaults to - false
 Returns- Boolean
 
-  
- inherited - on( eventName, listenerFunction, [ scopeObj ], [ listenerData ], [ priority ] ) → Object- CKEDITOR.dom.comment#on- 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 - thisobject). 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 - 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 ] : Boolean
- Indicates that the children elements must remain in the document, removing only the outer tags. - Defaults to - false
 Returns- node
- this 
 
-  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- Object
- Removed 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 : String
- The event name. 
- listenerFunction : Function
- The 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 : String
- A key used to identify the data slot. 
- value : Object
- The value to set to the data slot. 
 Returns- domObject
- This DOM object instance. 
 
Static methods
-  Implements the CKEDITOR.event features in an object. var myObject = { message: 'Example' }; CKEDITOR.event.implementOn( myObject ); myObject.on( 'testEvent', function() { alert( this.message ); } ); myObject.fire( 'testEvent' ); // 'Example'Parameters- targetObject : Object
- The object into which implement the features.
