Error in jquery

[makpaolo]

I'm not sure what MyBBEditor.updateOriginal(); means exactly and how to fix this type of thing. Assistance would be greatly appreciated with this.


Line 359 shows;

 $('#quick_reply_submit').on('click', function () {
        if (typeof MyBBEditor === 'object') {
            MyBBEditor.updateOriginal();
        }

        return false;
    });
