1.记住密码勾选,点登陆时,将账号和密码保存到cookie,下次登陆自动显示到表单内 2.不勾选,点登陆时候则清空之前保存到cookie的值,下次登陆需要手动输入
大体思路就是通过存/取/删cookie实现的;每次进入登录页,先去读取cookie,如果浏览器的cookie中有账号信息,就自动填充到登录框中,存cookie是在登录成功之后,判断当前用户是否勾选了记住密码,如果勾选了,则把账号信息存到cookie当中,效果图如上:
<div class="ms-login">
<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="0px" class="demo-ruleForm">
<el-form-item prop="username">
<el-input v-model="ruleForm.username" placeholder="用户名"></el-input>
</el-form-item>
<el-form-item prop="password">
<el-input type="password" placeholder="密码" v-model="ruleForm.password" @keyup.enter.native="submitForm('ruleForm')"></el-input>
</el-form-item>
<!-- `checked` 为 true 或 false -->
<el-checkbox v-model="checked">记住密码</el-checkbox>
<br>
<br>
<div class="login-btn">
<el-button type="primary" @click="submitForm('ruleForm')">登录</el-button>
</div>
</el-form>
</div>
//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('; '); //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.ruleForm.username = arr2[1]; //保存到保存数据的地方
} else if (arr2[0] == 'userPwd') {
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
}
浏览器中的cookie信息如下图,注意这里的cookie的expire/Max-Age过期时间,这个时间是格林尼治标准时间GMT,世界统一的时间,GMT+8小时就是北京时间。(这里不做加密功能)
