Vue 中循环绑定v-module表单

子组件有一个列表要做输入验证

<template>
  <div>
    <el-form :model="value" ref="numberValidateForm" label-width="100px" class="demo-ruleForm">
      <el-form-item
        v-for="(domain, index) in value.domains"
        :label="'域名' + index"
        :key="domain.key"
        :prop="'domains.' + index + '.value'"
        :rules="{
          required: true, message: '域名不能为空', trigger: 'change'
        }"
      >
        <el-input v-model="domain.value"></el-input>
      </el-form-item>
    </el-form>
  </div>
</template>

<script>
export default {

  props: {
    value: {
      type: Object,
      default: () => {}
    }
  },

  methods: {
    submitForm (formName) {
      return this.$refs.numberValidateForm.validate()
    }
  }
}
</script>

父组件收集子组件里面的数据然后再提交

<template>
  <div>
    <h1>验证表单</h1>
    <order-area ref="order" v-model="dynamicValidateForm"></order-area>
    <el-button
      type="primary"
      @click="handleClick"
    >
      提交
    </el-button>
  </div>
</template>

<script>
import OrderArea from './OrderArea'

export default {
  components: {
    OrderArea
  },
  data () {
    return {
      dynamicValidateForm: {
        domains: [{value: ''}, {value: ''}, {value: ''}]
      }
    }
  },

  methods: {
    handleClick () {
      this.$refs.order.submitForm().then((valid) => {
        console.log(valid, '提交表单')
      }, () => {
        console.log('提交错误')
      })
    }
  }
}
</script>
