     function getQueryObject(url) {
            url = url == null ? window.location.href : url;
            var search = url.substring(url.lastIndexOf("?") + 1);
            var obj = {};
            var reg = /([^?&=]+)=([^?&=]*)/g;
            search.replace(reg, function (rs, $1, $2) {
                var name = decodeURIComponent($1);
                var val = decodeURIComponent($2);
                val = String(val);
                obj[name] = val;
                // return rs;
                console.log(rs);
            });
            // return obj;
            console.log(obj);
