最近在做项目时遇到这样一个需求，一个form表单里面有两个字段数量不固定，可以动态的增删，在提交的时候不管数量有多少都需要验证，页面效果如下：

form表单对应的数据结构如下:

      voucherInfo: {
        cash: [
          {
            cashNum: '', // 押金流水号
            cashPayType: null, // 押金支付类型
          }
        ],
        cashPayTime: '', // 押金支付时间
        cashPayVoucher: [], // 押金支付凭证
        commissionNum: '', // 佣金流水号
        commissionPayType: null, // 佣金支付方式
        commissionPayTime: '', // 佣金支付时间
        commissionPayVoucher: [], // 佣金支付凭证
        remark: '' // 备注
      }

在这里主要考虑的就是如何验证voucherInfo的第一个字段，它是一个数组，数组里面又是一个对象，我们要验证这个对象的每个属性，简而言之，就是验证对象里面的数组里面的对象属性。

方法一：el-form里面再嵌套一个el-form

  <el-form
      ref="voucherForm"
      :rules="voucherRule"
      :model="voucherInfo"
      label-width="140px"
    >
      <div
        v-for="(item, index) in voucherInfo.cash"
        :key="index"
      >
      	<!-- 嵌套的el-form   model绑定的是voucherInfo.cash里面的对象 -->
      	<!-- 又定义了一个rules :rules="subVoucherRule"-->
        <el-form
          ref="subVoucherForm"
          :model="item"
          :rules="subVoucherRule"
          label-width="140px"
        >
          <el-row>
            <el-col :span="6">
              <el-form-item
                prop="cashNum"
                :label="'押金流水号' + (index + 1)"
              >
               <el-input
                v-model="item.cashNum"
                palceholder="请输入"
               >
               </el-input>
              </el-form-item>
            </el-col>
            <el-col :span="12">
              <el-form-item
                :label="'押金支付方式' + (index + 1)"
                prop="cashPayType"
              >
                <el-select
                  v-model="item.cashPayType"
                  placeholder="请选择"
                >

验证规则：

      voucherRule: {
        cashPayTime: [{ required: true, message: '请选择押金支付时间', trigger: 'change'}],
        cashPayVoucher: [{ required: true, message: '请上传押金支付凭证', trigger: 'change'}],
        commissionNum: [{ required: true, message: '请输入佣金流水号', trigger: 'blur'}],
        commissionPayType: [{ required: true, message: '请选择佣金支付方式', trigger: 'change'}],
        commissionPayTime: [{ required: true, message: '请选择佣金支付时间', trigger: 'change'}],
        commissionPayVoucher: [{ required: true, message: '请上传佣金支付凭证', trigger: 'change'}],
      },
      subVoucherRule: {
        cashNum: [{ required: true, message: '请输入押金流水号', trigger: 'blur'}],
        cashPayType: [{ required: true, message: '请选择押金支付方式', trigger: 'change'}],
      }

提交时验证代码：因为有两个form，所以两个都需要验证

 <el-form
      ref="voucherForm"
      :rules="voucherRule"
      :model="voucherInfo"
      label-width="140px"
    >
          <el-row
            v-for="(item, index) in voucherInfo.cash"
            :key="index"
          >
            <el-col :span="6">
            	<!--注意有改动的是这里   prop动态绑定cashNum   rules写在了这里 -->
              <el-form-item
                :prop="'cash['+index+'].cashNum'"
                :label="'押金流水号' + (index + 1)"

                }"
              >

          </el-form-item>
        </el-col>
      </el-row>
    </el-form>

方法二：直接把验证规则写在html中

 <el-form
      ref="voucherForm"
      :rules="voucherRule"
      :model="voucherInfo"
      label-width="140px"
    >
          <el-row
            v-for="(item, index) in voucherInfo.cash"
            :key="index"
          >
            <el-col :span="6">
            	<!--注意有改动的是这里   prop动态绑定cashNum   rules写在了这里 -->
              <el-form-item
                :prop="'cash['+index+'].cashNum'"
                :label="'押金流水号' + (index + 1)"
                :rules="{
                  required: true, message: '请输入押金流水号', trigger: 'blur'
                }"
              >
               <el-input
                v-model="item.cashNum"
                palceholder="请输入"
               >
               </el-input>
              </el-form-item>
            </el-col>
            <el-col :span="12">
            	<!--注意有改动的是这里   prop动态绑定cashPayType   rules写在了这里 -->
              <el-form-item
                :label="'押金支付方式' + (index + 1)"
                :prop="'cash['+ index +'].cashPayType'"
                :rules="{

                }"
              >
                <el-select
                  v-model="item.cashPayType"
                  placeholder="请选择"
                >
                  <el-option
                    v-for="i in cashPayTypeOptions"
                    :label="i.label"
                    :value="i.value"

                  >

      <el-row>
        <el-col :span="6">
          <el-form-item label="押金支付时间" prop="cashPayTime">
