         a = document.createElement('a');
         a.href = url;

         var demoRegex = /(?:^|[&;])demo=([^&;]+)/g,
         matches,
         demo = [];

         while (matches = demoRegex.exec(a.search)) {
            demo.push(decodeURIComponent(matches[1]));
         }

         document.write(demo);
      </script>
