js获取链接中的参数

<script>
    function GetRequest2(key) {
      var url = location.search;
      var theRequest = new Object();
      if (url.indexOf("?") != -1) {
        var str = url.substr(1);
        strs = str.split("&");
        for (var i = 0; i < strs.length; i++) {
          theRequest[strs[i].split("=")[0]] = unescape(strs[i].split("=")[1]);
        }
      }
      var value = theRequest[key];
      return value;
    }
    例如链接为：http://www.xxxx?uid=22&token=1231321542132
    var uid = GetRequest2("uid")
    var token = GetRequest2("token")
  </script>
