HomeWeChat AppletMini Program DevelopmentExample of how WeChat applet implements the non-swiper effect of the normal tab at the top

This article mainly introduces in detail the WeChat applet to achieve the effect of ordinary tabs at the top, which is not swiper, and has certain reference value. Interested friends can refer to it

Background: Some time ago I wrote a small program to grab red envelopes, which involved the top tab and pulled it out.

Rendering:

The code is directly below:

wxml:


<view class="navbar"> 
 <text wx:for="{{navbar}}" data-index="{{index}}" 
 class="item {{currentIndex==index?&#39;active&#39;:&#39;&#39;}}" 
 bindtap="navbarTab" wx:key="unique">{{item}}</text> 
 </view> 
 <view hidden="{{currentIndex!==0}}"> 

 </view> 
 <view hidden="{{currentIndex!==1}}"> 
 
 </view>


wxss:


.navbar{ 
 display: flex; 
 width: 100%; 
 flex-direction: row; 
 line-height: 80rpx; 
 position: fixed; 
 top: 0; 
} 
.navbar .item{ 
 flex: auto; 
 font-size: 30rpx; 
 text-align: center; 
 background: #fff; 
 font-weight: bold; 
} 
.navbar .item.active{ 
 color: #36DB2C; 
 position: relative; 
} 
.navbar .item.active::after{ 
 content: ""; 
 display: block; 
 position: absolute; 
 height: 4rpx; 
 bottom: 0; 
 left: 0; 
 right: 0; 
 background: #36DB2C; 
}


js:


data: { 
 navbar: ["我发出的", "我收到的"], 
 currentIndex: 0,//tabbar索引 
 }, 
 navbarTab: function (e) { 
 this.setData({ 
  currentIndex: e.currentTarget.dataset.index 
 }); 
 },

The above is the basic code of the implementation process, omitting the intermediate content code. The top number is recycled and can be set according to your actual needs.
