title: How can I detect when source of iframe is changed?
body: <p>I want to detect when user clicks a link in <code>iframe</code> and changes the source of <code>iframe</code>, because I want to resize it. Also I use jQuery. What is the best way to detect this?</p>
  
  <p>Actually I need something like this (this example is in jQuery, it does not work, I imagined this)</p>
  
  <pre><code>$('#iframe').live('load', function(){ alert('src is changed')});
  </code></pre>
