title: Locating a frame contained iframe from a sibling frame
body: <p>My web page is made of 2 <code>frame</code>s with the <code>name</code> and <code>id</code> attributes set to "left" and "center".</p>
  
  <p>I run a JS script in the left one to be able to locate/identify an <code>iframe</code> with <code>name</code> and <code>id</code> "monfrm" in the center frame.</p>
  
  <p>Here is the JavaScript I have so far:</p>
  
  <pre><code>x = top.document.getElementById("center");
  alert(x.src);   //fine
  // ok up to here
  y = x.getElementById("monfrm");  // attempting to locate my iframe within "center" frame &amp; that's where it hurts
  alert("left says" + y.width);   //eeh nothing
  </code></pre>
  
  <p>I'm probably getting old cos' it seems pitifully easy unless I missed a point.... :-)</p>
  
  <p>Any light shed welcome</p>
  
  <p>Thanks</p>
