Vue使用antd组件a-form-model实现数据连续添加功能

<a-form-model ref="ruleForm" :model="form" :rules="rules" :label-col="{ span: 5 }" :wrapper-col="{ span: 19 }">
	<a-form-model-item ref="zcfl" label="资产分类" prop="zcfl">
	  <!-- <a-input style="width: 60%" v-model="form.zcfl" /> -->
	  <a-form-model-item
		:prop="'zcfl.' + index + '.value'"
		:rules="{
		  required: true,
		  message: '请输入内容',
		  trigger: 'blur',
		}"
		v-for="(domain, index) in form.zcfl"
		:key="domain.key"
	  >
		<a-input v-model="domain.value" style="width: 40%; margin-right: 8px" />
		<a-icon
		  v-if="form.zcfl.length > 1"
		  class="dynamic-delete-button"
		  type="minus-circle-o"
		  :disabled="form.zcfl.length === 1"
		  @click="removeDomain(domain)"
		/>
	  </a-form-model-item>
	  <a-button type="dashed" style="width: 30%" @click="addDomain"> <a-icon type="plus" /> 添加分类 </a-button>
	</a-form-model-item>
</a-form-model>

form: {
	zcfl: [{ value: undefined, key: 1 }], //资产分类
},
rules: {
	zcfl: [{ required: true, message: '请输入!', trigger: 'blur' }],
},

// 添加分类
removeDomain(item) {
  let index = this.form.zcfl.indexOf(item)
  if (index !== -1) {
	this.form.zcfl.splice(index, 1)
  }
},
addDomain() {
  this.form.zcfl.push({
	value: '',
	key: Date.now(),
  })
},
