CKEDITOR 销毁

 

I've had similar issue where we were making several instances of CKeditor for the content loaded via ajax.

CKEDITOR.remove()

Kept the DOM in the memory and didn't remove all the bindings.

CKEDITOR.instance[instance_id].destroy()

Gave the error i.contentWindow error whenever I create new instance with new data from ajax. But this was only until I figured out that I was destroying the instance after clearing the DOM.

Use destroy() while the instance & it's DOM is present on the page, then it works perfectly fine.

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);
