This article mainly introduces the tab (TabBar at the top of the window) page switching in WeChat applet development. It has certain reference value. You can learn more if you need it.

Tabs are being developed in WeChat applet. Tabs in Android generally use fragments, but when it came to the applet, I was instantly confused.

Finally made it. Share it and have a look.

Look at the effect first:

Then add the code:

1.index.wxml

<!--index.wxml--> 
<view class="swiper-tab"> 
  <view class="swiper-tab-list {{currentTab==0 ? &#39;on&#39; : &#39;&#39;}}" data-current="0" bindtap="swichNav">哈哈</view> 
  <view class="swiper-tab-list {{currentTab==1 ? &#39;on&#39; : &#39;&#39;}}" data-current="1" bindtap="swichNav">呵呵</view> 
  <view class="swiper-tab-list {{currentTab==2 ? &#39;on&#39; : &#39;&#39;}}" data-current="2" bindtap="swichNav">嘿嘿</view> 
</view> 
 
<swiper current="{{currentTab}}" class="swiper-box" duration="300" style="height:{{winHeight - 31}}px" bindchange="bindChange"> 
  <!-- 我是哈哈 --> 
  <swiper-item> 
   <view>我是哈哈</view> 
  </swiper-item> 
  <!-- 我是呵呵 --> 
  <swiper-item> 
   <view>我是呵呵</view> 
  </swiper-item> 
  <!-- 我是嘿嘿 --> 
  <swiper-item> 
   <view>我是嘿嘿</view> 
  </swiper-item> 
</swiper>

     winHeight: reswindowHeight 
    }); 
   } 
 
  }); 
 }, 
 /**

 bindChange: function( e ) { 
 
  var that = this; 
  thatsetData( { currentTab: edetailcurrent });

 swichNav: function( e ) {
