iframe re-direct

[Diggerz]

Hi i was wondering how you would re-direct an iframe url if the requested url is not accessible?

im currently using a dynamic iframe example as below and want to add a re-direct if the requested iframe url is not accessible or times out

Code:

$(function() {
  function seturl(url) {
    $('.iframeurl').find('iframe').attr('src', url);
  }

  $('.btn-1').on('vclick', function() {
    seturl('https://forum.logicmachine.net');
  });

  $('.btn-2').on('vclick', function() {
    seturl('http://openrb.com');
  });
})

Since iframe points to a different domain you cannot access iframe document at all due to security reasons.
