微信小程序如何获取wx:for列表中点击行的信息

微信小程序如何获取wx:for列表中点击行的信息

1.如果想要获取点击行的索引(即for循环数组的索引)

<view class='chooseTitle'>
    <view class='choose' wx:for="{{monArray}}" wx:for-index="bindex" wx:key="item.id">
      <view class="itemName" bindtap='switchTab' data-bindex='{{bindex}}' data-id='{{item.id}}'>{{item}}</view>
    </view>
  </view>

JS代码

 switchTab: function (e) {
    console.log(e)
    var index = parseInt(e.currentTarget.dataset.index)
}

2.如果想要获取点击行的更详细信息

 <view class="weui-cells searchbar-result" wx:if="{{inputVal.length > 0}}" hidden="{{!resultShowed}}">
          <view wx:for="{{uplink}}" wx:for-item="item" wx:key="item.id" >
            <navigator url="" class="weui-cell" hover-class="weui-cell_active" data-item='{{item}}' data-id="item.id" bindtap="queryBtnClick">
              <view class="weui-cell__bd">
                  <view>{{uplink[index].name}}:{{uplink[index].text}}->{{downlink[index].text}}</view>
              </view>
            </navigator>
          </view>
        </view>
    </view>

JS

 queryBtnClick: function (e) {
    console.log("click", e)
    var clickitem = e.currentTarget.dataset.item
 }
