js获取当前url参数

 //抓取url参数
         function GetRequest() {
             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]);
                 }
             }
             return theRequest;
         }

调用：

 var Request = new Object();
            Request = GetRequest();
            var ip = Request['serverip']; //serverip相当于test.com/index.aspx?serverip=127.1.1.1
