html - Catch X-Frame-Options Error in javascript

Question

Is there any way to catch an error when loading an iframe from another domain. Here is an example in jsfiddle. http://jsfiddle.net/2Udzu/ . I need to show a message if I receive an error.

Here is what I would like to do, but it doesn't work:

$('iframe')[0].onerror = function(e) {
   alert('There was an error loading the iFrame');
}

Anyone have any ideas?

The onerror is applicable only for script errors. Frame content error checking must be done using any other method. Here's one example.

<script>
  function chkFrame(fr) {
    if (!fr.contentDocument.location) alert('Cross domain');
  }
</script>
<iframe src="http://www.google.com/" onload="chkFrame(this)"></iframe>

Due to cross domain restriction, there's no way to detect whether a page is successfully loaded or if the page can't be loaded due to client errors (HTTP 4xx errors) and server errors (HTTP 5xx errors).
