title: Return all page iFrames without id element
body: <p>I tried this the intuitive way with both JavaScript and jQuery, with no dice for either. </p>
  
  <pre><code>document.GetElementsByTagName('iframe');
  </code></pre>
  
  <p>got me:</p>
  
  <blockquote>
    <p>Uncaught TypeError: Object # has no method
    'GetElementsByTagName'</p>
  </blockquote>
  
  <p>and <code>$('iframe')</code>
  got me <code>undefined</code>. </p>
  
  <p>Is an iframe an element? Is there a way to do this? </p>
  
  <p>I'm trying to return all the page iframes.</p>
  
  <p>Thank you. </p>
