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( {

   }) 
  } 
 } 
}) 
//index.js
