<!-- 分类 -->
<view class='listMiddle swiper-tab'>
<view class='middle {{currentTab==0? "action" : ""}}' data-current="0" bindtap="clickTab">
全部
</view>
<view class='middle {{currentTab==1? "action":""}}' data-current="1" bindtap="clickTab">
分类1
</view>
<view class='middle {{currentTab==2? "action":""}}' data-current="2" bindtap="clickTab">

</view>
<view class='middle {{currentTab==3? "action":""}}' data-current="3" bindtap="clickTab">
分类3
</view>
</view>
<!-- 精选商品 -->
<swiper current="{{currentTab}}" duration="300" bindchange="swiperTab" >
//注意这里只是写了循环出来一条数据，要实现多条数据，要学会用数据嵌套循环哦~~
