title: IFrame call parent function
body: <p>is it possible for an iframe to call a parent's function, <strong>even if they are not in the same domain</strong>?
  My actual approach lifts a security error when they are not on the same domain:</p>
  
  <pre><code>&lt;script&gt;
  function test()
  { alert('wow');
  }
  &lt;/script&gt;
  &lt;iframe src="...."&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>And inside the iframe i would do this:</p>
  
  <pre><code>&lt;script&gt; 
  function fin() 
  { top.test(); } 
  &lt;/script&gt;
  </code></pre>
  
  <p>Many thanks :)</p>
