@devdesco-ceo, @daim2k5 ,
Hello All,

After applying fix as .prop('href', element.src)

New JS error is appearing:
Error: Permission denied to access property "document"
elem.contentDocument || elem.contentWindow.document : jquery.js (line 2998, col 1)

@adragus-inviqa,

This isn't working.
(function lookup(element) {
if ($.nodeName(element, "iframe") && $(element).prop('src').indexOf(window.location.hostname) != -1) { return; }
Its giving same error:
Error: Permission denied to access property "document"
elem.contentDocument || elem.contentWindow.document : jquery.js (line 2998, col 1)

Now if I change above code as:
if ($.nodeName(element, "iframe") ) { return; }

that is removing && $(element).prop('src').indexOf(window.location.hostname) != -1
This is working for me.

Can, I remove this condition "&& $(element).prop('src').indexOf(window.location.hostname) != -1" ?
Is there any other way of checking above condition
"&& $(element).attr('src').indexOf(window.location.hostname) != -1" is also giving error.

@adragus-inviqa,

These both are working

1. **($.nodeName(element, "iframe") ) { return; }**
   

   Or

2. **if ($.nodeName(element, "iframe")  && $('iframe').prop('src').indexOf(window.location.hostname) != -1) { return; }**
