vue3对象数组格式的动态表单校验

如你有一个表单，表单内容是对象，但是对象内还有可动态循环的数组进行动态表单校验。

效果如图：查看源码

页面内容：

<div class="arrForm-Box">
	<el-form :model="state.formData" :rules="rules" ref="formDataRef" label-width="80">
		<el-row :gutter="35">
			<el-col :xs="24" :sm="12" :md="12" :lg="12" :xl="12" class="mb10">
				<el-form-item label="账号" prop="account">
					<el-input v-model="state.formData.account" placeholder="账号" clearable />
				</el-form-item>
			</el-col>
			<el-col :xs="24" :sm="12" :md="12" :lg="12" :xl="12" class="mb10">
				<el-form-item label="密码" prop="password">
					<el-input v-model="state.formData.password" type="password" placeholder="密码" clearable />
				</el-form-item>
			</el-col>
			<el-col :xs="24" :sm="24" :md="24" :lg="24" :xl="24" class="mb20">
				<el-button size="small" class="w100" @click="add">新增</el-button>
			</el-col>
			<el-col :xs="24" :sm="24" :md="24" :lg="24" :xl="24" class="mb20">
				<el-row :gutter="35" v-for="(v, k) in state.formData.userList" :key="k">
					<el-col :xs="24" :sm="12" :md="12" :lg="12" :xl="12" class="mb20">
						<el-form-item label="姓名" :prop="`userList[${k}].name`" :rules="[{ required: true, message: `请输入姓名` }]">
							<template #label>
								<el-button type="danger" :icon="Delete" circle plain size="small" @click="remove(k)" />
								<span class="ml5">姓名</span>
							</template>
							<el-input v-model="state.formData.userList[k].name" placeholder="姓名" clearable />
						</el-form-item>
					</el-col>
					<el-col :xs="24" :sm="12" :md="12" :lg="12" :xl="12" class="mb20">
						<el-form-item label="年龄" :prop="`userList[${k}].age`" :rules="[{ required: true, message: `请输入年龄` },{ type: 'number', message: '请输入数字' }]">
							<el-input v-model.number="state.formData.userList[k].age" placeholder="年龄" clearable />
						</el-form-item>
					</el-col>
				</el-row>
			</el-col>
			<el-col :xs="24" :sm="12" :md="12" :lg="12" :xl="12">
				<el-form-item>
					<el-button type="primary" @click="submitForm()">提交</el-button>
					<el-button @click="resetForm()">重置</el-button>
				</el-form-item>
			</el-col>
		</el-row>
	</el-form>
</div>

逻辑代码：
表单对象单独写一个rules，里面的数组表单可直接索引动态绑定prop来设置

import {ref, reactive} from "vue";
import {Delete, Plus} from '@element-plus/icons-vue'

const formDataRef = ref(null);
const state = reactive({
	formData: {
		account: "",
		password: "",
		userList: []
	}
})

/* 规则 */
const rules = reactive({
	account: [
		{required: true,message: '请输入账号'},
	],
	password: [
		{required: true,message: '请输入密码'},
	],
})

/* 新增 */
const add = () => {
	if (state.formData.userList == undefined) state.formData.userList = [];
	state.formData.userList?.push({});
};

/* 删除 */
const remove = (index) => {
	state.formData.userList.splice(index, 1);
}

/* 提交 */
const submitForm = () => {
	formDataRef.value.validate(async (valid) => {
		if (!valid) return;
		console.log('submit: ',state.formData);
	})
}

/* 重置 */
const resetForm = () => {
	formDataRef.value.resetFields();
}
