微信小程序开发之选项卡(窗口顶部TabBar)页面切换

今天小编在收集效果的时候,发现了一个挺实用微信小程序的tab选项卡切换效果

tab.wxml

<view class="swiper-tab">
     <view class="swiper-tab-list {{currentTab==0 ? 'on' : ''}}" data-current="0" bindtap="swichNav">Tab1</view>
     <view class="swiper-tab-list {{currentTab==1 ? 'on' : ''}}" data-current="1" bindtap="swichNav">Tab2</view>
     <view class="swiper-tab-list {{currentTab==2 ? 'on' : ''}}" data-current="2" bindtap="swichNav">Tab3</view>
</view>

<swiper current="{{currentTab}}" class="swiper-box" duration="300" style="height:{{winHeight - 31}}px" bindchange="bindChange">
    <swiper-item>
        <view>Tab1页面</view>
    </swiper-item>
   <swiper-item>
       <view>Tab2页面</view>
   </swiper-item>
   <swiper-item>
       <view>Tab3页面</view>
   </swiper-item>
</swiper>

tab.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; }

tab.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
        })
     }
   }
})
