wxml

<view class="tapNav">
 <view class="pw_tabArr.tabCurrentIndex==0?'active':''" data-index="0" bindtap="veHandle">分页标签1</view>
 <view class="pw_tabArr.tabCurrentIndex==1?'active':''" data-index="1" bindtap="veHandle">分页标签2</view>
 <view class="pw_tabArr.tabCurrentIndex==2?'active':''" data-index="2" bindtap="veHandle">分页标签3</view>
</view>
<swiper id="swiper" indicator-dots="pw_indicatorDots"
 autoplay="pw_autoplay" interval="pw_interval" duration="pw_duration" current="pw_current" bindchange="swiperChange">
 <block wx:for="pw_imgUrls">
 <swiper-item id="swiper-item">
  <image id="imgae" src="pw_item" class="slide-image" width="355" height="150"/>
 </swiper-item>
 </block>

</swiper>

1.横向排列分页标签
2.每个分页标签各占1/3
