vue项目实现记住密码到cookie功能(附源码)

HTML

<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-f

JS

    //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

                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();

            },
            //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
            }
