title: Get Element from Object
body: <p>I've got this</p>
  
  <pre><code>var fou = foubar.getContent();
  </code></pre>
  
  <p>where <code>getContent</code> is </p>
  
  <blockquote>
    <p>Returns a jQuery object wrapping the dialog's content region - everything inside the frame, excluding the title bar.</p>
  </blockquote>
  
  <p>Thing is there are textbox values inside of fou I'd like to get at.
  I've tried this below, but it doesn't work.</p>
  
  <pre><code>  fou.$('#textbox1').val();
  </code></pre>
  
  <p>How can I select elements of <code>fou</code>?</p>
