本文實例講述了微信小程序開發實現的選項卡(窗口頂部/底部TabBar)頁面切換功能。分享給大家供大家參考，具體如下：

微信小程序開發中選項卡.在android中選項卡一般用fragment,到了小程序這里瞬間懵逼了.

總算做出來了.分享出來看看.

先看效果:

再上代碼:

1.index.wxml

<!--index.wxml--><view class="swiper-tab">  <view class="swiper-tab-list {{currentTab==0 ? 'on' : ''}}" data-current="0" bindtap="swichNav">哈哈</view>  <view class="swiper-tab-list {{currentTab==1 ? 'on' : ''}}" data-current="1" bindtap="swichNav">呵呵</view>  <view class="swiper-tab-list {{currentTab==2 ? 'on' : ''}}" 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>

2.index.wxss

/**index.wxss**/.swiper-tab{  width: 100%;  border-bottom: 2rpx solid #777777;  text-align: center;  line-height: 80rpx;}.swiper-tab-list{ font-size: 30rpx;  display: inline-block;  width: 33.33%;  color: #777777;}.on{ color: #da7c0c;  border-bottom: 5rpx solid #da7c0c;}.swiper-box{ display: block; height: 100%; width: 100%; overflow: hidden; }.swiper-box view{  text-align: center;}

3.index.js

//index.js//獲取應用實例var app = getApp()Page( { data: {  /**    * 頁面配置    */  winWidth: 0,  winHeight: 0,  // tab切換  currentTab: 0, }, onLoad: function() {  var that = this;  /**   * 獲取系統信息   */  wx.getSystemInfo( {   success: function( res ) {    that.setData( {     winWidth: res.windowWidth,     winHeight: res.windowHeight    });   }  }); }, /**   * 滑動切換tab   */ bindChange: function( e ) {  var that = this;  that.setData( { currentTab: e.detail.current }); }, /**  * 點擊tab切換  */ swichNav: function( e ) {  var that = this;  if( this.data.currentTab === e.target.dataset.current ) {   return false;  } else {   that.setData( {    currentTab: e.target.dataset.current   })  } }})

之前沒有上傳代碼.這是下圖的代碼

這樣一個類似viewpage的頂部選項卡就出來了.

微信小程序開發中窗口底部tab欄切換頁面很簡單很方便.
