解析查询字符串

        getQueryStringArgs() {
            // 取得查询字符串并去掉开头的问号
            const qs = (location.search.length > 0 ? location.search.substring(1) : '');
            // 保存数据的对象
                const args = {};
                const items = qs.length ? qs.split('&') : [];

                let value = null;
                const len = items.length;
            for (let i = 0; i < len; i++) {
                item = items[i].split('=');
                name = decodeURIComponent(item[0]);
                value = decodeURIComponent(item[1]);
