    <view class="swiper-tab-list {{currentTab==0 ? 'on' : ''}}" data-current="0" bindtap="swichNav">11</view>    
    <view class="swiper-tab-list {{currentTab==1 ? 'on' : ''}}" data-current="1" bindtap="swichNav">22</view>    
    <view class="swiper-tab-list {{currentTab==2 ? 'on' : ''}}" data-current="2" bindtap="swichNav">33</view>  
    <view class="swiper-tab-list {{currentTab==3 ? 'on' : ''}}" data-current="3" bindtap="swichNav">44</view>  
    <view class="swiper-tab-list {{currentTab==4 ? 'on' : ''}}" data-current="4" bindtap="swichNav">55</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-item>    
      <view>我是嘿嘿</view>    
    </swiper-item>    
    <swiper-item>    
      <view>我是嘿嘿</view>    
    </swiper-item>    
</swiper>    

.swiper-tab{    
    width: 100%;    
    border-bottom: 2rpx solid #777777;

.swiper-box view{    
    text-align: center;    
}    

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    
      })    
    }     
  },  
 /** 
  * 点击分享 
  */  
  onShareAppMessage: function () {  
    return {  
      title: '装逼小程序',  
      path: '/page/user?id=123'

<!--index.wxml-->  
<view class="container">

//index.js  
//获取应用实例

  data: {  
    motto: 'Hello World',

调用登陆接口 app.js

  },  
  getUserInfo:function(cb){  
    var that = this;  
    if(this.globalData.userInfo){  
      typeof cb == "function" && cb(this.globalData.userInfo)  
    }else{  
      //调用登录接口  
      wx.login({  
        success: function () {  
          wx.getUserInfo({  
            success: function (res) {  
              that.globalData.userInfo = res.userInfo;  
              typeof cb == "function" && cb(that.globalData.userInfo)  
            }  
          })  
        }  
      });  
    }  
  },  
  globalData:{  
    userInfo:null  
  }  
})
