js通過問號後面拿參數

     $(function () {
        var search = location.search;
       // alert(search); //獲取URL中?後的句子
        var string = search.split("=")[1]; //分割取出cid
        // alert(string);
        var games = getParameter("game"); //通過getParameter獲取
        if(games){
          alert(games);

        }
        //根據傳遞過來的參數name獲取對應的值
        function getParameter(name) {
            var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)","i");
            var r = location.search.substr(1).match(reg);
            if (r!=null) return (r[2]); return null;
        }
    });
