小程序循环列表的展开收起

展开

<view class='investDetail' style='margin-top:30rpx;' wx:for="{{carInsurance}}" wx:key="index">
 <view bindtap='clickLine' data-index="{{index}}"><view class='th1' style='font-size: 36rpx;'><text>方案{{index+1}}</text>
</view>
//判断展开收起
 <view wx:if="{{item.show}}"></view>
  //展开后显示类容已省略
</view>

通过获取下标，然后判断显示

clickLine: function (e) {
  var that = this;
  var indexs = e.currentTarget.dataset.index
  var carInsurance = this.data.carInsurance
  carInsurance[indexs].show = !carInsurance[indexs].show ||false
  that.setData({
   carInsurance: carInsurance
  })
 },
