vue 模板循环绘制多行上传文件功能

我们在上传多个文件时， 循环绘制模板， el-upload 拿不到当前操作的节点 ， 可以在其外层增加一个div 加上点击事件，记下当前操作节点， 代码如下

<el-form-item 
    :label="val.label+'：'" 
    v-for="(val, key, index) of orther_license_info" 
    :key="key + '_'+index"
    :prop="key">
    
      <el-col :span="8">
         <el-input
          type="text"
          readonly
          v-model="conf[key]"
          ></el-input>
      </el-col>
      
      <el-col offset="1" :span="7">
        <div  @click="fileDivClick(key)">
          <el-upload
            :on-change="fileChange"
            :show-file-list="false"
            :auto-upload="false"
            :accept="key!=='otherQualification'?'image/jpeg,image/png':'image/jpeg,.zip'"
            >
            <el-button slot="trigger" type="primary" style="width: 83px" >{{val.sltFlg?"已选择":"选择文件"}}</el-button>

            <el-button class="margin-left-10" type="primary" @click="uploadFile(key)">上传文件</el-button>
          </el-upload>

        </div>
         
      </el-col>
    </el-form-item>

事件

 fileDivClick(curKey){
      this.curKey = curKey
  },

    fileChange(file, fileList) {  

    }
