     <swiper-item data-id="{{item.id}}" data-url="{{item.linkUrl}}" class="dot{{index == swiperCurrent ? ' active' : ''}}" bindtap="chuangEvents" id="{{index}}">
      <image src="{{item.picUrl}}" class="img"></image>
      <span>{{item.index+1}}</span>
     </swiper-item>
    </block>
   </swiper>
   <view class="dots">
    <swiper autoplay="auto" interval="5000" display-multiple-items="7" duration="500" current="{{dotsCurrent}}" circular="{{circular}}" bindchange="dotsChange">
     <block wx:for="{{slider}}" wx:key="unique">
