Test two methods of retrieving QueryString values with javascript.

Preparation HTML

<script>
  var query = "q=my+search+query&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, " "));
  }
