The form under ElementPlus also has a new form. If you write H5, etc. and don’t find a suitable one, you can also package it yourself.
Realize 3 code explanations: 1: Code of ElementPlus 2: Code written by myself 3: Encapsulate the code of 2 by myself
1: The running effect of ElementPlus
click submit

2. The amount of code is too much and we will package it
3: Encapsulate the code of 2 by yourself
components/insertForm.vue
<template>
<div>
<template v-for="(item, index) in NewdataForm" :key="item.id">
<div
class="box-b bg-ff"
style="display: flex; justify-content: space-between"
>
<div>
<div style="display: flex">
<div class="">区域位置</div>
<input v-model="item.ipchange" type="text" />
</div>
<div style="display: flex; margin-top: 10px">
<div class="">危险有害因素</div>
<input type="text" v-model="item.errorText" />
</div>
</div>
<div>
<el-button type="primary" @click="deleteClick(item.id)"
>删除</el-button
>
</div>
</div>
</template>
</div>
</template>
<script setup lang="ts">
import {
ref, reactive, watch } from "vue";
const emit = defineEmits(["deleteClick"]);
const define = withDefaults(defineProps<{
dataForm: any[] }>(), {
dataForm: () => [
{
id: 1, ipchange: "", errorText: "" },
{
id: 2, ipchange: "", errorText: "" },
],
});
//1: 这样不可以的; 下面的watch监听进行赋值的时候 NewdataForm=newvalue不可整体的赋值这个
// reactive 只能赋值到它下的某个属性下
//1: let errors = reactive( [...define.dataForm] );
// 2:但是使用这个 太麻烦
// 2:let NewdataForm = reactive({ dataForm: [...define.dataForm] });
// 3:使用 ref这个 可以直接赋值
let NewdataForm = ref([...define.dataForm]);
watch(define.dataForm, (newvalue) => {
// errors=newvalue //错误的写法 如上1:
// NewdataForm.dataForm=newvalue;可以正常运行如上2:
NewdataForm.value = newvalue;
});
const deleteClick = (id: number) => {
emit("deleteClick", id);
};
defineExpose({
