element ui使用v-for循环form表单校验的实现

<template>
  <el-form :model="dynamicValidateForm" ref="dynamicValidateForm" label-width="120px" class="demo-dynamic">
    <el-row v-for="(domain, index) in dynamicValidateForm.persons" :key="domain.key">
      <el-col :span="8">
        <el-form-item :label="'姓名' + index+1" :prop="'persons.' + index + '.name'" :rules="rules.name">
          <el-input v-model="domain.name"></el-input>
        </el-form-item>
      </el-col>
      <el-col :span="8">
        <el-form-item :label="'手机号码' + index+1" :prop="'persons.' + index + '.iphone'" :rules="rules.iphone">
          <el-input v-model="domain.iphone"></el-input>
        </el-form-item>
      </el-col>
      <el-col :span="8">
        <el-form-item :label="'身份证号码' + index+1" :prop="'persons.' + index + '.idCard'" :rules="rules.idCard">
          <el-input v-model="domain.idCard"></el-input>
        </el-form-item>
      </el-col>
    </el-row>
    <el-form-item>
      <el-button type="primary" @click="submitForm('dynamicValidateForm')">提交</el-button>
      <el-button @click="addPerson">新增人员</el-button>
      <el-button @click="resetForm('dynamicValidateForm')">重置</el-button>
    </el-form-item>
  </el-form>
