title: Retrieve values from http://m.facebook.com/ajax/dtsg.php
body: <p>I need to retrieve values from <a href="http://m.facebook.com/ajax/dtsg.php" rel="nofollow">http://m.facebook.com/ajax/dtsg.php</a>.
  The page source of it contains:</p>
  
  <pre><code>for (;;);"":"","token":"AQDUdkLT","expire":1320259533,"":"
  </code></pre>
  
  <p><code>"token":"AQDUdkLT"</code> is unique for each user, so I can't use php.
  I need some client side method to retrieve those values.</p>
