本文主要和大家分享微信小程序选项卡功能的开发,希望能帮助到大家
在pages文件里面创建swipertab文件夹
1.编写页面结构:swipertab.wxml
<!--swipertab.wxml--> <view class="swiper-tab"> <view class="swiper-tab-list {{currentTab==0 ? 'on' : ''}}" data-current="0" bindtap="swichNav">tab一</view> <view class="swiper-tab-list {{currentTab==1 ? 'on' : ''}}" data-current="1" bindtap="swichNav">tab二</view> <view class="swiper-tab-list {{currentTab==2 ? 'on' : ''}}" data-current="2" bindtap="swichNav">tab三</view> </view> <swiper current="{{currentTab}}" class="swiper-box" duration="300" style="height:{{winHeight - 31}}px" bindchange="bindChange"> <!-- tab一 --> <swiper-item> <view>tab一</view> </swiper-item> <!-- tab二 --> <swiper-item> <view>tab二</view> </swiper-item> <!-- tab三 --> <swiper-item> <view>tab三</view> </swiper-item> </swiper>
2.设置数据:swipertab.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 }) } } })
3.设置样式:swipertab.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; }
4.头部标题修改:swipertab.json
{ "navigationBarTitleText": "选项卡页面切换" }
5.效果图
注意:因为文件名不是index,所以记得修改app.json文件(底下备注的地方),否则页面不会显示同时底部不会显示
