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.

Answer 1

The i.contentWindow is null error seems to occur when calling destroy on an editor instance that was tied to a textarea no longer in the DOM.

CKEDITORY.destroy takes a parameter noUpdate.

The APIdoc states:

If the instance is replacing a DOM element, this parameter indicates whether or not to update the element with the instance contents.

So, to avoid the error, either call destroy before removing the textarea element from the DOM, or call destory(true) to avoid trying to update the non-existent DOM element.

if (CKEDITOR.instances['textarea_name']) {
   CKEDITOR.instances['textarea_name'].destroy(true);
}
