在列表中对某个单独的view赋值

如图：

在这个table中 我想对aa赋值，需要怎么做呢怎么通过view id赋值？

代码：

<view class="container">     <view class="table">         <view class="tr">             <view class="th">标题1</view>             <view class="th">标题2</view>             <view class="th">标题3</view>             <view class="th">标题4</view>             <view class="th">标题5</view>         </view>         <view class="tr" wx:for="{{userInfo}}">             <view class="td">id</view>             <view class="td" id="id_{{item.id}}" data-hi="2" data-id="99" bindtap="editStatus">{{item.name}}</view>             <view class="td">5</view>             <view class="td">6</view>             <view class="td">7</view>         </view>     </view> </view>
