1，在微信小程式for迴圈裡面新增input事件，並把input輸入值新增到列表裡面

2.wxml

    <view class="item"   wx:for="{{list}}" wx:for-item="vo" wx:key="index"   data- 
   item="{{vo}}">
  <view class="col">{{vo.name}}</view>
  <view class="col2">{{vo.task_startTime}}</view>
  <view class="col2">{{vo.task_endTime}}</view>
  <view class="col">{{vo.work_hours}}</view>
  <view class="col stepper"  >
    <input data-id="{{index}}" value="{{vo.money}}" bindfocus="bindFocus" bindinput="bindKeyInput"></input>
  </view>
</view>
 

js

data:{
 list:[
     {
        name:'嘻嘻',
        task_startTime:'2020/12/03 12:56',
        task_endTime:'2020/12/03 15:56',
        work_hours:'3.0',
        money:0
      }
    ],
 inputValue: '',
    focusId: ''
},
 bindFocus: function (event) {
    let id = event.currentTarget.dataset.id
    console.log(id)
    this.setData({
      focusId: id
    })
  },

  bindKeyInput: function (event) {
       let that = this;
    let value = Number(event.detail.value)
    let id = event.currentTarget.dataset.id
  
   
    var up = 'list[' + id + '].money';
    this.setData({
      [up]:value 
    })

    console.log(that.data.focusId)
    console.log(that.data.list)
   
  },
