微信小程序Swiper高度自适应问题

  onUpdateSwiperImage (e) {

    setTimeout(() => {
      const query = Taro.createSelectorQuery()
      query
        .select('.swiper-img')
        .boundingClientRect()
        .exec((rectArr) => {
          if (rectArr.length == 0) return;

          let maxHeight = rectArr[0].height;
          rectArr.forEach((rect) => {
            if (rect.height > maxHeight) {
              maxHeight = rect.height
            }
          })
          this.setState({ swiperHeight: maxHeight })

        })
    }, 200);
  }
