文章详细描述了在Vue项目中如何使用el-form进行表单的动态循环校验，包括设置`prop`属性处理多层数据结构，以及如何在每个el-form-item上设置独立的验证规则。

在项目中经常会遇到表单的功能，表单的循环校验可能有一点点不同

一层循环中：

<template>
	<el-form :model="form" :rules="rules" ref="form" label-width="100px" class="demo-ruleForm">
		<el-form-item label="班级" prop="class">
			<el-input v-model="form.class"></el-input>
		</el-form-item>
		<el-form-item label="活动区域" prop="region">
			<el-select v-model="form.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>
		<el-row v-for="(item,index) in form.formList" :key="index">
			<el-col :span="12">
				<el-form-item label="姓名" :prop="`formList.${index}.name`" :rules="rules.name">
					<el-select v-model="item.name" placeholder="请选择活动区域">
						<el-option label="区域一" value="shanghai"></el-option>
						<el-option label="区域二" value="beijing"></el-option>
					</el-select>
				</el-form-item>
			</el-col>
			<el-col :span="12">
				<el-form-item label="年龄" :prop="`formList.${index}.age`" :rules="rules.age">
					<el-input v-model="item.age"></el-input>
				</el-form-item>
			</el-col>
		</el-row>
		<el-form-item>
			<el-button type="primary" @click="submitForm">立即创建</el-button>
			<el-button @click="resetForm">重置</el-button>
		</el-form-item>
	</el-form>
</template>
<script>
	export default {
		data() {
			return {
				form: {
					class: '',
					region: '',
					formList: [{
							name: '',
							age: ''
						},
						{
							name: '',
							age: ''
						}
					]
				},
				rules: {
					class: [{
						required: true,
						message: '请输入班级名称',
						trigger: 'blur'
					}],
					region: [{
						required: true,
						message: '请选择活动区域',
						trigger: 'change'
					}],
					name: [{
						required: true,
						message: '请输入姓名',
						trigger: 'blur'
					}],
					age: [{
						required: true,
						message: '请输入年龄',
						trigger: 'blur'
					}]
				}
			};
		},
		methods: {
			submitForm() {
				this.$refs.form.validate((valid) => {
					if (valid) {
						alert('submit!');
					} else {
						console.log('error submit!!');
						return false;
					}
				});
			},
			resetForm() {
				this.$refs.form.resetFields();
			}
		}
	}
</script>

两层循环：

<template>
	<el-form :model="form" :rules="rules" ref="form" label-width="100px" class="demo-ruleForm">
		<el-form-item label="班级" prop="class">
			<el-input v-model="form.class"></el-input>
		</el-form-item>
		<el-form-item label="活动区域" prop="region">
			<el-select v-model="form.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>
		<el-row v-for="(item,index) in form.formList" :key="index">
			<template v-for="(v,i) in item">
				<el-col :span="12">
					<el-form-item label="姓名" :prop="`formList.${index}.${i}.name`" :rules="rules.name">
						<el-select v-model="v.name" 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>
				</el-col>
				<el-col :span="12">
					<el-form-item label="年龄" :prop="`formList.${index}.${i}.age`" :rules="rules.age">
						<el-input v-model="v.age"></el-input>
					</el-form-item>
				</el-col>
			</template>
		</el-row>
		<el-form-item>
			<el-button type="primary" @click="submitForm">立即创建</el-button>
			<el-button @click="resetForm">重置</el-button>
		</el-form-item>
	</el-form>
</template>
<script>
	export default {
		data() {
			return {
				form: {
					class: '',
					region: '',
					formList: [
						[{
								name: '',

					]

				},
				rules: {
