实现功能：
1、登录时勾选记住密码，用cookie保存账号和密码并对密码进行两次加密处理（纯前端），下次登录自动输入账号密码
2、登录时不勾选，清空cookie，下次登录需要输入
效果图：

加密方法我用的base64和CryptoJS 大家记得去下载

// 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 = "password" + "=" + c_pwd + ";path=/;expires=" + exdate.toGMTString();
},
// 读取cookie
getCookie: function() {
if (document.cookie.length > 0) {
//checked为true
this.checked=true
var arr = document.cookie.split('; ');
for (var i = 0; i < arr.length; i++) {
var arr2 = arr[i].split('=');
if (arr2[0] == 'username') {
this.ValidateForm.username = arr2[1];
} else if (arr2[0] == 'password') {
// Decrypt 解密
let bytes = CryptoJS.AES.decrypt(arr2[1],key)
let originalText=bytes.toString(CryptoJS.enc.Utf8)
// base64解密
let pwd=Base64.decode(originalText)
this.ValidateForm.password = pwd;
}
}
}
},
// 清除cookie
clearCookie: function() {
this.setCookie("", "", -1); // 修改2值都为空，天数为负1天就好了
},

一定要创建后读取cookie

this.getCookie()
