本文实例讲述了微信小程序开发实现的选项卡(窗口顶部/底部TabBar)页面切换功能。分享给大家供大家参考，具体如下：
微信小程序开发中选项卡.在android中选项卡一般用fragment,到了小程序这里瞬间懵逼了.
总算做出来了.分享出来看看.
先看效果:
再上代码:
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//获取应用实例var app = getApp()Page( { data: { /** * 页面配置 */ winWidth: 0, winHeight: 0, // tab切换 currentTab: 0, }, onLoad: function() { var that = this; /** * 获取系统信息 */ wx.getSystemInfo( { success: function( res ) { that.setData( { winWidth: res.windowWidth, winHeight: res.windowHeight }); } }); }, /** * 滑动切换tab */ bindChange: function( e ) { var that = this; that.setData( { currentTab: e.detail.current }); }, /** * 点击tab切换 */ swichNav: function( e ) { var that = this; if( this.data.currentTab === e.target.dataset.current ) { return false; } else { that.setData( { currentTab: e.target.dataset.current }) } }}) 之前没有上传代码.这是下图的代码

这样一个类似viewpage的顶部选项卡就出来了.
微信小程序开发中窗口底部tab栏切换页面很简单很方便.
代码:
1.app.json
//app.json{ "pages":[ "pages/index/index", "pages/logs/logs" ], "window":{ "backgroundTextStyle":"light", "navigationBarBackgroundColor": "#999999", "navigationBarTitleText": "tab", "navigationBarTextStyle":"white" }, "tabBar": { "color": "#ccc", "selectedColor": "#35495e", "borderStyle": "white", "backgroundColor": "#f9f9f9", "list": [ { "text": "首页", "pagePath": "pages/index/index", "iconPath": "images/home.png", "selectedIconPath": "images/home-actived.png" }, { "text": "目录", "pagePath": "pages/catalogue/catalogue", "iconPath": "images/note.png", "selectedIconPath": "images/note-actived.png" }, { "text": "我的", "pagePath": "pages/mine/mine", "iconPath": "images/profile.png", "selectedIconPath": "images/profile-actived.png" } ] }} pagePath是页面路径.iconPath是图片路径，icon 大小限制为40kb.
selectedIconPath:选中时的图片路径，icon 大小限制为40kb
tab Bar的最多5个,最少2个.
在pages目录下写好页面即可切换.
希望本文所述对大家微信小程序开发有所帮助。
