title: Reference parent window document
body: <p>I'm trying to access the parent window document from a popup.</p>
  
  <pre><code>&lt;script type='text/javascript'&gt;
      $(document).ready(function(){
          var summary = window.parent.document.getElementById('summary');
          var content = summary.innerHTML;
      });
  &lt;/script&gt;
  </code></pre>
  
  <p>Is it even possible? Is there a jQuery specific way to do it?</p>
  
  <p>Thanks</p>
