JS part

  //页面加载调用获取cookie值
  mounted() {
    this.getCookie();
  },
  methods: {
    submitForm(formName) {
             const self = this;
            //判断复选框是否被勾选 勾选则调用配置cookie方法
            if (self.checked == true) {
              console.log("checked == true");
              //传入账号名，密码，和保存天数3个参数
              self.setCookie(self.ruleForm.username, self.ruleForm.password, 7);
            }else {
             console.log("清空Cookie");
             //清空Cookie
             self.clearCookie();
            }
            
            //与后端请求代码，本功能不需要与后台交互所以省略
            
            console.log("登陆成功");
         
        });
      },
      //设置cookie
      setCookie(c_name, c_pwd, exdays) {
        var exdate = new Date(); //获取时间
        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();
        window.document.cookie = "userPwd" + "=" + c_pwd + ";path=/;expires=" + exdate.toGMTString();
      },
      //读取cookie
      getCookie: function() {
        if (document.cookie.length > 0) {
          var arr = document.cookie.split(&#39;; &#39;); //这里显示的格式需要切割一下自己可输出看下
          for (var i = 0; i < arr.length; i++) {
            var arr2 = arr[i].split(&#39;=&#39;); //再次切割
            //判断查找相对应的值
            if (arr2[0] == &#39;userName&#39;) {
              this.ruleForm.username = arr2[1]; //保存到保存数据的地方
            } else if (arr2[0] == &#39;userPwd&#39;) {
              this.ruleForm.password = arr2[1];
            }
          }
        }
      },
      //清除cookie
      clearCookie: function() {
        this.setCookie("", "", -1); //修改2值都为空，天数为负1天就好了
      }
