title: Simple redirect to URL from select drop down in FACEBOOK iframe
body: <p><em>I'm sure this shouldn't be so hard!</em></p>
  
  <p>I've been struggling with <strong>facebook's javascript</strong>: I need to redirect to a URL based on the value in a select drop down menu, something like:</p>
  
  <pre><code>&lt;form name="cityselect"&gt;
      &lt;select name="menu" onChange="location=document.cityselect.menu.options[document.cityselect.menu.selectedIndex].value;" value="GO"&gt;
          &lt;option value="http://www.leeds.html"&gt;Leeds&lt;/option&gt;
          &lt;option value="http://www.manchester.html"&gt;Manchester&lt;/option&gt;
      &lt;/select&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Can anybody help me get this working? I've had good look though the facebook dev forum and docs but either don't understand what needed or can't find the answer!</p>
