Encountering the WRONG_DOCUMENT_ERR: DOM Exception 4 error when attempting to close Fancybox after making edits in inline Tiny

I am encountering a problem with my fancybox that includes a form for collecting user input, which features a tinyMCE editor. When trying to close the fancybox after making substantial edits in the TinyMCE, whether by clicking the close X or submitting the form, I experience an issue. The fancybox closes, but there is a repetitive loop in the console logging "WRONG_DOCUMENT_ERR: DOM Exception 4" before removing the shadow overlay. Disabling the overlay did not resolve the looping error.

Similar errors occur in Firefox due to attempting to manipulate DOM nodes across different elements, possibly because the newly added elements to the TinyMCE (such as images or list items) do not align with the DOM tree Fancybox is attempting to close.

Has anyone encountered a similar challenge and found a solution?

Answer №1

After conducting some research online without success, I decided to experiment and eventually stumbled upon this effective solution.

If you're facing a similar issue, consider using the onCleanup command in fancybox options:

$.fancybox(data_html,{
    onComplete:function(){
        //initialize tinymce in your form at this point                
    },
    onCleanup:function(){
        // remove tinymce and any HTML content in your form just 
        // before closing the modal window
        $('#your_form').html('');
    }
});

I hope this suggestion proves to be helpful!
