            // 获取参数
                getQueryVariable(variable) {
                    var query = window.location.search.substring(1);
                    var vars = query.split("&");
                    for (var i = 0; i < vars.length; i++) {
                        var pair = vars[i].split("=");
                        if (pair[0] == variable) { return pair[1]; }
