url中search字符串解析为json对象

    var url = "http://www.taobao.com/index.php?key0=0&key1=1";        var obj = parseQueryString(url);              function parseQueryString(argu){          var str = argu.split('?')[1];          var result = {};          var temp = str.split('&');          for(var i=0; i<temp.length; i++)          {             var temp2 = temp[i].split('=');             result[temp2[0]] = temp2[1];          }          return result;        }
