需求:點(diǎn)擊重置按鈕,重置登陸表單
1.在表單中引入ref="loginFormRef"屬性,loginFormRef值可以自定義;
2.給重置按鈕綁定點(diǎn)擊事件:@click="resetLoginForm";
3.實(shí)現(xiàn)點(diǎn)擊事件觸發(fā)的方法,得到引入的屬性值對(duì)象,調(diào)用resetFields方法,即:this.$refs.loginFormRef.resetFields()
代碼如下:
<template>
<div class="login-container">
<div class="login_box">
<!--頭像區(qū)域-->
<div class="avatar_box">
<img src="../assets/logo.png">
</div>
<!--登陸表單區(qū)域-->
<el-form ref="loginFormRef" :model="loginForm" :rules="loginFormRules" label-width="0px" class="login_form">
<!--用戶名-->
<el-form-item prop="username">
<el-input v-model="loginForm.username" prefix-icon="el-icon-user-solid"></el-input>
</el-form-item>
<!--密碼-->
<el-form-item prop="password">
<el-input v-model="loginForm.password" type="password" prefix-icon="el-icon-lock"></el-input>
</el-form-item>
<!--按鈕區(qū)域-->
<el-form-item class="btns">
<el-button type="primary">登陸</el-button>
<el-button type="info" @click="resetLoginForm">重置</el-button>
</el-form-item>
</el-form>
</div>
</div>
</template>

// 1.在需要校驗(yàn)的表單上綁定校驗(yàn)規(guī)則::rules="loginFormRules";

// { min: 3, max: 10, message: '長度在 3 到 10 個(gè)字符', trigger: 'blur' }],password: []};
// 3.在需要校驗(yàn)的具體表單上引入prop="username"屬性。
