Vue3、Element Plus使用v-for循环el-form表单进行校验

news 来源：原创 2024/7/6 15:01:06

在开发中遇到了这样一个需求

有一个form是通过v-for生成出来的，并且数量不确定，每个表单中的字段都需要做校验，就将自己的解决方法记录了下来。

在这里插入图片描述

完整代码如下

<template><div class="for-form"><el-button type="primary" @click="addHandle">新 增</el-button><div class="form-box"><div class="form-item" v-for="(item, index) in formList" :key="index"><el-form :model="item" :rules="rules" label-width="auto" style="max-width: 300px" label-position="top":ref="($event) => handle($event, index)"><el-form-item label="名称" prop="name"><el-input v-model="item.name" placeholder="请输入名称" /></el-form-item><el-form-item label="手机号" prop="phone"><el-input v-model="item.phone" placeholder="请输入手机号" /></el-form-item><el-form-item label="性别" prop="sex"><el-radio-group v-model="item.sex"><el-radio :value="1" size="small">男</el-radio><el-radio :value="2" size="small">女</el-radio></el-radio-group></el-form-item><el-form-item label="爱好" prop="hobby" v-if="item.sex == 2"><el-input v-model="item.hobby" placeholder="请输入爱好" /></el-form-item></el-form></div></div><el-button type="primary" @click="saveHandle">保 存</el-button></div>
</template><script setup lang="ts">
import { reactive, toRefs } from 'vue'const state = reactive({form: {} as any,formList: [] as any,rules: {name: [{ required: true, message: 'Please input Activity name', trigger: 'blur' },],},formRefs: [] as any
})const { formList, rules } = toRefs(state)function addHandle() {state.formList.push({name: "",phone: "",sex: 1,hobby: "",})
}function handle(e: any, index: any) {// 保存下每个refstate.formRefs[index] = e
}async function saveHandle() {let isSubmit: boolean[] = []// 循环上面记录下来的ref对每个进行校验for (const el of state.formRefs) {await el.validate((valid: any) => {// 每个 ref 校验成功或者失败都以布尔值存储下来if (valid) {isSubmit.push(true)} else {isSubmit.push(false)}})}// 只有当 isSubmit 存的值全是 true 时表示每个表单都校验成功了// 然后就可以提交了let has = isSubmit.every(i => i == true)if (has) {console.log("可以提交")}console.log(state.formRefs)console.log(isSubmit)
}</script><style scoped lang="scss">
.form-box {display: flex;align-items: flex-start;.form-item {margin-right: 20px;}
}
</style>
