window location href 跳转之后怎么获得后面带参数

 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;
         }
console.log(GetRequest().goods_id);  //输出5

 window.location.href = "../user/confirmation_order.html?goods_id=5" //携带数据
