CKEditor instance already exists

Question

I am using jquery dialogs to present forms (fetched via AJAX). On some forms I am using a CKEditor for the textareas. The editor displays fine on the first load.

Whe

Answer 1

CKEDITOR.instances = new Array();

I am using this before my calls to create an instance (ones per page load). Not sure how this affects memory handling and what not. This would only work if you wanted to replace all of the instances on a page.

Answer 2

This functions works for me in CKEditor version 4.4.5, it does not have any memory leaks

 function CKEditor_Render(CkEditor_id) {
        var instance = CKEDITOR.instances[CkEditor_id];
        if (CKEDITOR.instances.instance) {
            CKEDITOR.instances.instance.destroy();
        }
        CKEDITOR.replace(CkEditor_id);
    }

// call this function as below

var id = 'ckeditor'; // Id of your textarea

CKEditor_Render(id);

Answer 3

I had exactly the same problem like jackboberg. I was using dynamic form loading into jquery dialogs then attaching various widgets (datepickers, ckeditors etc...). And I tried all solutions noted above, none of them worked for me.

For some reason ckeditor only attached the first time I loaded form, the second time I got exactly the same error message jackboberg did.

I've analyzed my code and discovered that if you attach ckeditor in "mid-air" that is while form content is still not placed into dialog, ckeditor won't properly attach its bindings. That is since ckeditor is attached in "mid-air", second time you attach it in "mid-air"... poof ... an error is thrown since the first instance was not properly removed from DOM.

This was my code that ptoduced the error:

var $content = $(r.content); // jQuery can create DOM nodes from html text gotten from <xhr response> - so called "mid-air" DOM creation
$('.rte-field',$content).ckeditor(function(){});
$content.dialog();

This is the fix that worked:

var $content = $(r.content).dialog(); // first create dialog
$('.rte-field',$content).ckeditor(function(){}); // then attach ckeditor widget

Answer 4

I learned that

delete CKEDITOR.instances[editorName];

by itself, actually removed the instance. ALL other methods i have read and seen, including what was found here at stackoverflow from its users, did not work for me.

In my situation, im using an ajax call to pull a copy of the content wrapped around the and 's. The problem happens to be because i am using a jQuery .live event to bind a "Edit this document" link and then applying the ckeditor instance after success of the ajax load. This means, that when i click another link a link with another .live event, i must use the delete CKEDITOR.instances[editorName] as part of my task of clearing the content window (holding the form), then re-fetching content held in the database or other resource.

Answer 5

remove class="ckeditor" , it might have triggered ckeditor initialization

Answer 6

I had this problem too, but I solved it in a much simpler way...

I was using the class "ckeditor" in my jQuery script as the selector for which textareas I wanted use for CKEditor. The default ckeditor JS script also uses this class to identify which textareas to use for CKEditor.

This meant there is a conflict between my jQuery script and the default ckeditor script.

I simply changed the class of the textarea and my jQuery script to 'do_ckeditor'(you could use anything except "ckeditor") and it worked.
