出现 “component lists rendered with v-for should have explicit keys.”警告
修改前:
<div>
<p class="mianFont"><img :src="imgurl" class="imgStyle">查看附件</p>
<el-row v-for="item in attachmentList" >
<el-col :span="12" v-for="obj in item" >
<el-button type="text" @click="getPicture(obj.fileType)">{
{obj.name}}</el-button>
</el-col>
</el-row>
</div>
改正后:
<div>
<p class="mianFont"><img :src="imgurl" class="imgStyle">查看附件</p>
<el-row v-for="(item,index) in attachmentList" :key="index">
<el-col :span="12" v-for="(obj,index) in item" :key="index">
<el-button type="text" @click="getPicture(obj.fileType)">{
{obj.name}}</el-button>
</el-col>
</el-row>
</div>
