vue+element 重置表单

1.首先看效果图（官方的）

2.输入框配置

1.el-form标签中添加:model="" 和ref=""两个属性，属性值必须和data return中定义的对象名一样；
2.el-form-item标签中需要添加 prop属性，属性值和此el-form-item标签内输入框的v-model对象属性名一致，如v-model=“ruleForm.name” prop=“name”

html标签：
<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
  <el-form-item label="活动名称" prop="name">
    <el-input v-model="ruleForm.name"></el-input>
  </el-form-item>
  <el-form-item label="活动区域" prop="region">
    <el-select v-model="ruleForm.region" placeholder="请选择活动区域">
      <el-option label="区域一" value="shanghai"></el-option>
      <el-option label="区域二" value="beijing"></el-option>
    </el-select>
  </el-form-item>

script定义的属性：
data() {
    
    
      return {
    
    
        ruleForm: {
    
    
          name: '',
          region: '',
          date1: '',
          date2: '',
          delivery: false,
          type: [],
          resource: '',
          desc: ''
        }

3.重置方法

1.解决方法一：
重置按钮：
<el-button @click="resetForm('ruleForm')">重置</el-button>

resetForm(formName) {
    
    
  this.$refs[formName].resetFields();
}
方法二：
<el-button @click="resetForm()">重置</el-button>

resetForm() {
    
    
  this.$refs.ruleForm.resetFields();
}

4.官方demo
