title: Track button click within a iframe
body: <p>Is it possible to track a button click within an iFrame if i don't have control over the external website or it's contents? </p>
  
  <p>(very fictionnal example)if i had an iframe like this:</p>
  
  <pre><code>&lt;iframe src="http://www.johnny.com/plugins/like.php?href=http%253A%252F%252Fexample.com%252Fpage%252Fto%252Flike&amp;amp;layout=standard&amp;amp;show_faces=true&amp;amp;width=450&amp;amp;action=like&amp;amp;font&amp;amp;colorscheme=light&amp;amp;height=80" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:80px;" allowTransparency="true"&gt;&lt;/iframe&gt;
  </code></pre>
