From out of an external script:
When placing the editor in the page, you give it an "instance name". To retrieve it, you must simply call the FCKeditorAPI.GetInstance method. For example:
var oEditor = FCKeditorAPI.GetInstance('InstanceName') ;
From out of a dialog of the editor:
Call the InnerDialogLoaded to get the FCK Object. Read more in this
var oEditor = window.parent.InnerDialogLoaded().FCK ;
Both methods return the main FCKeditor object that gives the necessary bridge to interact with it. These are the most useful properties and methods of this object:
Properties: * Name = (string) The instance name. * Status = (integer) The editor status (loading status). * EditorDocument = (object) The DOM Document object for the editing area. * EditorWindow = (object) The DOM Window object for the editing area. Methods: * AttachToOnSelectionChange( functionPointer ) * Focus() * GetXHTML( formatted ) * InsertElement(element) * InsertElementAndGetIt(e) * InsertHtml(html) // Inserts HTML in the current cursor position * IsDirty() // Checks if the content in the editor has been changed * MakeEditable() * ResetIsDirty() // Resets the dirty state * SetHTML( html ) // Sets the contents of the editor // Note that when using this method, you will loose any listener that you // may have previously registered on the editor.EditorDocument. * GetHTML() // retrieves the edited html from the editor. * SwitchEditMode() * UpdateLinkedField()
Once the editor loading phase is complete and it is ready to use (and interact with JavaScript), a standard function is called in the page that contains the editor, if the function is defined. This function must be named "FCKeditor_OnComplete" and receives the related editor instance as the parameter. Using it, you can execute any initial code that may interact with the editor. This is a declaration example:
function FCKeditor_OnComplete( editorInstance ) { alert( editorInstance.Name ) ; }
Other than the above standard function, every FCKeditor instance has an "Event" object that can be used to listen for events to be fired. For example, the following code listens for the "OnSelectionChange" to execute custom code:
function FCKeditor_OnComplete( editorInstance ) { editorInstance.Events.AttachEvent( 'OnSelectionChange', DoSomething ) ; } var counter = 0 ; function DoSomething( editorInstance ) { // This is a sample function that shows in the title bar the number of times // the "OnSelectionChange" event is called. window.document.title = editorInstance.Name + ' : ' + ( ++counter ) ; }
Note that every event callback function receives the editor instance as a parameter.
The following is the list of events available:
Fired when something is pasted in the editor. The function you specify must return true for the paste to proceed.
The following are a few samples of things that can be done with the JavaScript API. (In these samples, oEditor = FCKeditorAPI.GetInstance('InstanceName').)
Insert HTML at cursor position:
oEditor.InsertHtml(HTML);
Triggering a toolbar button / command:
oEditor.Commands.GetCommand(commandName).Execute();
(See more info in the HOWTO in the forums: link=dead)
Disabling toolbar buttons:
oEditor.EditorWindow.parent.FCKToolbarItems.LoadedItems[commandName].Disable();
(See more info in the HOWTO in the forums: ) (Using the Disable function of a button is the proper way of disabling instead of overwriting the Execute command of a button, which is described in the first post of the HOWTO thread)
Setting a config value:
oEditor.Config[''] = 'newValue';
Change editor document style at runtime:
oEditor.EditorDocument.body.style.cssText += 'color: #322805; background-color: #F7C928;' ;
Working with the selection in the editor: Use the Selection Object, see link=dead
Set or get anything of the editor:
FCKeditorAPI.GetInstance('InstanceName').EditorWindow.parent...
(See more info in the HOWTO in the forums: link=dead)
Add a dynamic Save function
This allows you to assign a function that gets called when the Save button is clicked or the default save key is pressed (CTRL-SHIFT-S):
// called on save function doSave(){ alert('Saved.'); document.getElementById('someElement').innerHTML = 'Saved!'; return false; //this disables default action (submitting the form) } // called when FCKeditor is done starting.. function FCKeditor_OnComplete( editorInstance ){ editorInstance.LinkedField.form.onsubmit = doSave; }
找了好久,才找到,save对应的驱动函数,太爽了。
动态调用FCK终于完全解决了,几天功夫没有白费!
