<el-autocomplete
 v-model="state4"
 :fetch-suggestions="querySearchAsync"
 placeholder="请输入内容"
 @select="handleSelect"
></el-autocomplete>

@select="handleSelect(item, index)" // 这样肯定不行的

<el-autocomplete
 v-model="state4"
 :fetch-suggestions="querySearchAsync"
 placeholder="请输入内容"
 @select="((item)=>{handleSelect(item, index)})" // 写个闭包就可以了，index表示第几个组件
></el-autocomplete>

<input :value="scope.row.confirmAmount" @change="updateConfirmAmount(scope.row)" placeholder="请输入审核数量" />

 <input :value="scope.row.confirmAmount" @change="updateConfirmAmount($event, scope.row)" placeholder="请输入审核数量" /> 

<code class="language-html"><!-- 明细列表 --> 
<el-table :data="midSubmitDetailTableData"  border stripe style="width: 100%"> 
  <el-table-column prop="submitAmount" label="本次交工数量"></el-table-column> 
  <el-table-column prop="confirmAmount" label="审核数量">

updateConfirmAmount(data, row){
  var _value = data.currentTarget._value;
