function PageQuery(q) {
  if (q.length > 1) this.q = q.substring(1, q.length);
  else this.q = null;
  this.keyValuePairs = new Array();
  if (q) {
    for (var i = 0; i < this.q.split("&").length; i++) {
      this.keyValuePairs[i] = this.q.split("&")[i];
    }
  }
  this.getKeyValuePairs = function () { return this.keyValuePairs; }
  this.getValue = function (s) {
    for (var j = 0; j < this.keyValuePairs.length; j++) {
      if (this.keyValuePairs[j].split("=")[0] == s)
        return this.keyValuePairs[j].split("=")[1];
    }
    return false;
  }
  this.getParameters = function () {
    var a = new Array(this.getLength());
    for (var j = 0; j < this.keyValuePairs.length; j++) {
      a[j] = this.keyValuePairs[j].split("=")[0];
    }
    return a;
  }
  this.getLength = function () { return this.keyValuePairs.length; }
}
function queryString(key) {
  var page = new PageQuery(window.location.search);
  return unescape(page.getValue(key));
}
