title: Get iframe html or name from parent window
body: <p>I have a page that loads few iframe's within itself. 
  Each iframe can invoke parent function.
  For example like this:</p>
  
  <pre><code>$(document).ready(function() {
    parent.test();
  }
  </code></pre>
  
  <p>I want to be able to find which iframe invoked test function.
  I've tried to play with calleer.called properties but the best I could get is the function that calling test().
  In my case it was $(document).ready function.
  Is there a way to get the name of iframe (or it's html name) which calling the function?</p>
