und was macht dieses script:

<script type="text/javascript" language="javascript">
   function getQueryVariable(variable) {
   var query = window.location.search.substring(1);
   var vars = query.split("&");
   for (var i=0;i<vars.length;i++) {
   var pair = vars[i].split("=");
   if (pair[0] == variable) {
   return pair[1];
   }
   }
   return "";
  }
  </script>
