var app=getApp() Page({ data:{ currentTab:0 }, onLoad: function (options){ // 页面初始化 options为页面跳转所带来的参数 }, //滑动切换 swiperTab: function ( e ){ var that= this ; that.setData({ currentTba:e.detail.current }); }, //点击切换 clickTab: function ( e ) { var that = this ; if ( this .data.currentTab === e.target.dataset.current ) { return false ; } else { that.setData( { currentTab: e.target.dataset.current }) } } }) |
