  1. 登录时,调用该方法
    remenberPsw() {
      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.loginForm.username, self.loginForm.password, 7);
      } else {
        console.log("清空Cookie");
        //清空Cookie
        self.clearCookie();
      }
    }
  1. 设置cookie
    setCookie(c_name, c_pwd, exdays) {
      console.log("设置cookie");
      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();
    }

3.读取cookie

    getCookie: function() {
      console.log(document.cookie, "获得cookie");
      if (document.cookie.length > 0) {
        var arr = document.cookie.split("; "); //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("="); //再次切割
          //判断查找相对应的值
          if (arr2[0] == "userName") {
            this.loginForm.username = arr2[1]; //保存到保存数据的地方
          } else if (arr2[0] == "userPwd") {
            this.loginForm.password = arr2[1];
          }
        }
      }
    }

4.清除cookie

    clearCookie: function() {
      this.setCookie("", "", -1); //修改2值都为空,天数为负1天就好了
    }

5.使用:vue项目中在mounted的时候获得cookie

  mounted() {
    this.getCookie(); /* 获得cookie */
  }

6.template中使用

 <el-checkbox class="checked" v-model="checked">记住密码</el-checkbox>
