效果以下:html
我用了很笨的方法實現的,大體就是:xss
1.當前點擊的div(view)若是先後都有內容,那麼,當前div(view)就設置到中間,前一個就設置到左邊,前一個的前面全部所有設置到最左邊,後面一個設置到右邊,後面全部設置到最右邊this
2.當前點擊的div(view)若是前面無內容,即第一個,那麼,當前div(view)設置到中間,後面一個設置到右邊,後面全部設置到最右邊url
3.當前點擊的div(view)若是後面無內容,即最後一個,那麼,當前div(view)設置到中間,前面一個設置到左邊,前面全部設置到最左邊spa
1.html 3d
<view class='idx-content'> <view class='idx-swiper'> <view class='idx-cswp {{item.swpClass}}' wx:for="{{swiperList}}" wx:key="" bindtap="swpBtn" data-index="{{index}}"> <image src='{{item.imgsrc}}' mode='widthFix'></image> <view class='swp-title' hidden="{{item.swpClass!=='swp-center'}}"> <view class='swp-btime'>{{item.time}}</view> <view class='swp-bname'>{{item.bname}}</view> </view> </view> </view> </view>
注:swp-title是標題,用hidden替代wx:if是由於會頻繁切換。code

若是要實現滑動切換,可用 bindtouchstart 和 bindtouchend 來實現。 思路大概是滑動了必定距離以後就添加class。blog
