微信小程序开发之实现选项卡(窗口顶部TabBar)页面切换

时间:2021-05-18

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.indexwxss

/**indexwxss**/ 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%; 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 */ wxgetSystemInfo( { success: function( res ) { thatsetData( { winWidth: reswindowWidth, winHeight: reswindowHeight }); } }); }, /** * 滑动切换tab */ bindChange: function( e ) { var that = this; thatsetData( { currentTab: edetailcurrent }); }, /** * 点击tab切换 */ swichNav: function( e ) { var that = this; if( thisdatacurrentTab === etargetdatasetcurrent ) { return false; } else { thatsetData( { currentTab: etargetdatasetcurrent }) } } })

这样一个类似viewpage的顶部选项卡就出来了.
