小程序最顶部横向日历

不多说，看图说话。

 

 最终的效果就是左右可以滑动选择日期，点击日期查询数据。

WXML

<!-- 横向日期 -->
      <swiper class="swiper" display-multiple-items="{{clientWidthCount}}">
        <block wx:for="{{Dates}}" wx:key="{{item.id}}">
          <swiper-item id="{{item.id}}" bindtap="ClickDateCheng">
            <text class="swiper-xingqi {{dateCurrentStr==item.id?'selZhou':''}}">{{item.text}}</text>
            <image class="{{dateCurrentStr==item.id?'selImg':''}}" src="{{bgWhiteImgUrl}}" />
            <text class="swiper-day {{dateCurrentStr==item.id?'selDay':''}}">{{dateCurrentStr==item.id?item.mon+'-'+item.day:item.day}}</text>
            <text class="swiper-price {{dateCurrentStr==item.id?'selPrice':''}}">{{item.price}}</text>
          </swiper-item>
        </block>
      </swiper>
      <view class="data-month">
