Try this:

Must be used after the page is fully loaded, so in page onload or used in a function after loading is complete.

XML

function IsFullScreen( )
{
      // Variables
      var intScreenHeight = window.screen.height;
      var intBodyOffSet = document.body.offsetHeight;
      var intFullScreenDifference = 26;
      var blnIsFullScreen = false; // Assume No
      // Does the Screen Height - the Body offset = Full Screen Difference
      if( ( intScreenHeight - intBodyOffSet ) == intFullScreenDifference )
      {
            // Yes, were full screen
            blnIsFullScreen = true;
      }
      // Return
      return blnIsFullScreen;
}

</script>

<html>
      <body onload="alert( IsFullScreen( ) );">
      <br>
      <br>
      <br>
      <br>
      <br>
      <br>
      <br>
      <br>
      <br>
      <br>
      </body>
</html>

Good luck!
