小程序顶部可滚动导航

需求是 小程序做头部做导航分类的效果

顶部用 scroll-view 组件横向滚动，类似tab选项卡的效果，内容用类似模板方式引用，可重复利用

<scroll-view class="scroll-view_H" scroll-x="{{true}}" style=" 100%">
    <view wx:for="{{classify}}" wx:key="id" data-type="{{item.id}}" class="scroll-view-item_H {{curTab==item.id?'sv-item-on':'sv-item-off'}}" bindtap="classifyClick">
      {{item.name}}
    </view>
</scroll-view>

  <block wx:if="{{curTab ==0}}"> <include src="recommend.wxml"/> </block>
  <block wx:elif="{{curTab==1}}"> <include src="fuli.wxml"/> </block>
  <block wx:elif="{{curTab==2}}"> <include src="other.wxml"/> </block>
  <block wx:elif="{{curTab==3}}"> <include src="other.wxml"/> </block>
  <block wx:elif="{{curTab==4}}"> <include src="other.wxml"/> </block>
  <block wx:elif="{{curTab==5}}"> <include src="other.wxml"/> </block>
  <block wx:else> <include src="other.wxml"/> </block>
