        exdate.setTime(exdate.getTime() + 24 * 60 * 60 * 1000 * exdays); //保存的天数
        //字符串拼接cookie
        window.document.cookie ="userName" + "=" + c_name + ";path=/;expires=" + exdate.toGMTString();

                for (let i = 0; i < arr.length; i++) {
                    let arr2 = arr[i].split("="); //再次切割
                    //判断查找相对应的值

                    }
                }
            }
        },
        //清除cookie
        clearCookie() {
            this.setCookie("", "", -1); //修改两个值都为空,天数为负1天
        }
