需求:点击重置按钮,重置登陆表单
1.在表单中引入ref="loginFormRef"属性,loginFormRef值可以自定义;
2.给重置按钮绑定点击事件:@click="resetLoginForm";
3.实现点击事件触发的方法,得到引入的属性值对象,调用resetFields方法,即:this.$refs.loginFormRef.resetFields()
代码如下:
<template> <div class="login-container"> <div class="login_box"> <!--头像区域--> <div class="avatar_box"> <img src="../assets/logo.png"> </div> <!--登陆表单区域--> <el-form ref="loginFormRef" :model="loginForm" :rules="loginFormRules" label-width="0px" class="login_form"> <!--用户名--> <el-form-item prop="username"> <el-input v-model="loginForm.username" prefix-icon="el-icon-user-solid"></el-input> </el-form-item> <!--密码--> <el-form-item prop="password"> <el-input v-model="loginForm.password" type="password" prefix-icon="el-icon-lock"></el-input> </el-form-item> <!--按钮区域--> <el-form-item class="btns"> <el-button type="primary">登陆</el-button> <el-button type="info" @click="resetLoginForm">重置</el-button> </el-form-item> </el-form> </div> </div> </template> <script> export default { data () { return { loginForm: { username: 'li', password: 'zz' }, // 1.在需要校验的表单上绑定校验规则::rules="loginFormRules"; // 2.在data中定义loginFormRules规则对象:loginFormRules:{username: [{ required: true, message: '请输入用户名', trigger: 'blur' }, // { min: 3, max: 10, message: '长度在 3 到 10 个字符', trigger: 'blur' }],password: []}; // 3.在需要校验的具体表单上引入prop="username"属性。 loginFormRules: { username: [ { required: true, message: '请输入用户名', trigger: 'blur' }, { min: 3, max: 10, message: '长度在 3 到 10 个字符', trigger: 'blur' } ], password: [ { required: true, message: '请输入密码', trigger: 'blur' }, { min: 6, max: 15, message: '长度在 6 到 15 个字符', trigger: 'blur' } ] } } }, methods: { // 点击重置按钮,重置登陆表单 // 1.在表单中引入ref="loginFormRef"属性,loginFormRef值可以自定义; // 2.给重置按钮绑定点击事件:@click="resetLoginForm"; // 3.实现点击事件触发的方法,得到引入的属性值对象,调用resetFields方法,即:this.$refs.loginFormRef.resetFields() resetLoginForm () { this.$refs.loginFormRef.resetFields() } } } </script> <style lang="less" scoped> .login-container { background-color: #2b4b6b; height: 100%; .avatar_box { height: 130px; width: 130px; position: absolute; left: 50%; transform: translate(-50%,-50%); background-color: white; border: 1px solid #eee; border-radius: 50%; padding: 10px; box-shadow: 0 0 10px #ddd; img { height: 100%; width: 100%; border-radius: 50%; background-color: #eee; } } } .login_form { position: absolute; bottom: 0; width: 100%; padding: 0 20px; box-sizing: border-box; } .login_box { background-color: #fff; height: 300px; width: 450px; border-radius: 3px; position: absolute; left: 50%; top: 50%; transform: translate(-50%,-50%); } .btns { /*尾部对齐*/ display: flex; justify-content: flex-end; } </style>
