实现记住密码的操作，如下图所示 html部分
<el-form-item style="margin-top:-10px;margin-bottom:-5px;" > <el-checkbox v-model="checked" style="color:#a0a0a0;margin-top:-10px;">记住密码</el-checkbox> </el-form-item> <el-form-item style="margin-top:-10px;margin-bottom:-5px;" > <el-checkbox v-model="checked" style="color:#a0a0a0;margin-top:-10px;">记住密码</el-checkbox> </el-form-item>data部分
checked: true,methods部分 点击登录时
submitForm(userInfo) { const self = this; 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.userInfo.user, self.userInfo.pass, 7); } else { // console.log("清空Cookie"); //清空Cookie self.clearCookie(); } }设置cookie
//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.userInfo.user = arr2[1]; //保存到保存数据的地方 } else if (arr2[0] == "userPwd") { this.userInfo.pass = arr2[1]; } } } },清除cookie
//清除cookie clearCookie: function() { this.setCookie("", "", -1); //修改2值都为空，天数为负1天就好了 },在mounted里面获取cookie
mounted() { this.getCookie(); }本文大部分参考 肖敏 的技术博客 https://www.cnblogs.com/nxmin/p/8386031.html
