var url = location.search; //获取url中"?"符后的字串
    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]);
      }
    }
