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();
}
)
