Revision 5 of this test case created

Info

Test two methods of retrieving QueryString values with javascript.

Preparation code

<script>
  var query = "q=my+search+query&amp;value=55";
 
  window.GetQueryString = function(q) {
   return (function(a) {
    if (a == "") return {};
    var b = {};
    for (var i = 0; i < a.length; ++i) {
     var p = a[i].split('=');
     if (p.length != 2) continue;
     b[p[0]] = decodeURIComponent(p[1].replace(/\+/g, " "));
    }
    return b;
   })(q.split("&"));
  };
 
  window.getParameterByName = function(name) {
   name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
   var regexS = "[\\?&]" + name + "=([^&#]*)";
   var regex = new RegExp(regexS);
   var results = regex.exec(window.location.href);
   if (results == null) return "";
   else return decodeURIComponent(results[1].replace(/\+/g, " "));
  }
