Sometimes it is useful to obtain the dimensions of the users browser window. The following JavaScript code can be used to obtain the height and width :

<script type="text/javascript">

<!--



  var v_width;

  var v_height;

  

  // Standards compliant browsers (mozilla/netscape/opera/IE7)

  // use window.innerWidth and window.innerHeight

  

  if (typeof window.innerWidth != 'undefined')

  {

    v_width = window.innerWidth,

    v_height = window.innerHeight

  } else if (typeof document.documentElement != 'undefined'

          && typeof document.documentElement.clientWidth != 'undefined'

          && document.documentElement.clientWidth != 0) {

    // IE6 in standards compliant mode

    // (i.e. with a valid doctype)

    v_width = document.documentElement.clientWidth,

    v_height = document.documentElement.clientHeight

  } else {

    // older versions of IE

    v_width = document.getElementsByTagName('body')[0].clientWidth,

    v_height = document.getElementsByTagName('body')[0].clientHeight

  }

  document.write('<p>Viewport size : ' + 

                  v_width + 'x' + 

                  v_height + '</p>');

</script>
