swiper的卡顿问题
swiper 来回左右滑动，滑动7,8次，就会卡死，官方的demo也一样，也会卡死

郁闷啊，
<swiper class="swiper" current="{{currentTab}}" duration="200" bindchange="swiperChange" bindanimationfinish="animationfinish"> <swiper-item> <view id="fist-swiper-item">我是tab1---- index =1</view> </swiper-item> <swiper-item> <view>我是tab2---- index =2</view> </swiper-item> <swiper-item> <view>我是tab3---- index =3</view> </swiper-item> <swiper-item> <view>我是tab4---- index =4</view> </swiper-item> <swiper-item> <view>我是tab5----index = 5</view> </swiper-item> </swiper> |
// swiper 滑动切换 swiperChange(e) { console.log(e.detail.current, 'e.detail.current', e.detail, 'e.detail~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~') console.log(this.data.currentTab, '原来 this.data.currentTab-swiperChange~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`') var that = this if (e.detail.source == 'touch') { if (e.detail.current == 0 && that.data.currentTab > 1) { that.setData({ currentTab: that.data.currentTab }) } else if (e.detail.current == 0 && that.data.currentTab == 1) { wx.createSelectorQuery().select('#fist-swiper-item').boundingClientRect(function (rect) { //rect.id // 节点的ID //rect.dataset // 节点的dataset //rect.left // 节点的左边界坐标 console.log(rect.left) }).exec() console.log(e) that.setData({ currentTab: e.detail.current }) } else { that.setData({ currentTab: e.detail.current }) } } }, |
