为什么_this.divFormList[0] = divFormListArr不刷新视图
_this.divFormList = divFormListArr可以刷新视图
代码如下
<template>
<div class="form-container">
<div class="btn-container">
<el-button type="primary">添加表格</el-button>
</div>
<div
v-for="(itemDiv, indexDiv) in divFormList"
:key="'divForm' + indexDiv"
:class="{ 'div-form-container':true, 'mt10':false}"
>
<div class='form-delete-container'>
<el-button
icon='el-icon-delete'
size='small'
>
</el-button>
</div>
<el-form
style="margin-top: 5px"
:label-position="labelPosition"
ref="form"
:model="form"
label-width="80px">
<el-row
v-for="(itemRow, indexRow) in itemDiv"
:key="'row' + indexRow"
>
<el-col :span="12" v-for="(item, index) in itemRow" >
<el-form-item
:label="item.description"
:key="index"
style="box-sizing: border-box;padding-right: 5px"
>
<el-input v-model="item.name" size="small"></el-input>
</el-form-item>
</el-col>
</el-row>
</el-form>
</div>
</div>
</template>
