我有这个一个界面 实现

dataArray:[{id:'1',name:'一斤',items:[{id:'2',name:'大',price:0,stock:0},{id:'3',name:'中',price:0,stock:0}] },{...}]

现在有个问题 我输入几次之后 会把之前的内容覆盖

比如 ：输入第一行(价格+库存) 1 2

输入 第三行(价格+库存) 4 5

后面打印输出 一三行的结果值都是 4 5 值被覆盖了 我不知道是真么原因

    <view class="content-item-head">
      <view class="head-item"></view>
      <view class="head-item">规格</view>
      <view class="head-item">价格(元)</view>
      <view class="head-item">库存(件)</view>
    </view>
    <view class="content-item-row {{ idx%2==0?'itemBackground':'' }}" wx:key="index" wx:for="{{item.items}}" wx:for-item="obj" wx:for-index="idx">
      <view class="head-item ">{{idx==filters.toFix(item.items.length/3) ? item.name :''}}</view>
      <view class="head-item"> {{obj.name}} </view>
      <view class="head-item">
        <input class="item-input" bindblur="onInput"  data-type='price' data-pindex="{{index}}" data-index="{{idx}}"   maxlength="6" placeholder="￥输入金额" type="digit" value="{{ obj.price }}" ></input>
      </view>
      <view class="head-item">
        <input class="item-input"     bindblur="onInput"    data-type='stock' data-pindex="{{index}}" data-index="{{idx}}"   maxlength="5" placeholder="输入库存" type="number" value="{{ obj.stock}}"></input>
      </view>
   
    </view>



  </view>

onInput(e) {

    var value = e.detail.value 
    let index = e.currentTarget.dataset.index //子容器的index
    let pindex = e.currentTarget.dataset.pindex //父容器的index 
    let type = e.currentTarget.dataset.type //父容器的index  
    if (type == 'price') {
      value = this.money(value)//处理金额价格
      
    }  
    let key = 'dataArray[' + pindex + '].items[' + index + '].' + type

    this.setData({
      [key]: value
    })
  
  },
