微信小程序生命周期

1.应用的生命周期

App({
  onLaunch: function() { 
    // Do something initial when launch.
  },
  onShow: function() {
      // Do something when show.
  },
  onHide: function() {
      // Do something when hide.
  },
  onError: function(msg) {
    console.log(msg)
  },
  globalData: 'I am global data'
})

 

2.页面的生命周期

Page({
  data: {
    text: "This is page data."
  },
  onLoad: function(options) {
    // Do some initialize when page load.
  },
  onShow: function() {
    // Do something when page show.
  },
  onReady: function() {
    // Do something when page ready.
  },
  onHide: function() {
    // Do something when page hide.
  },
  onUnload: function() {
    // Do something when page close.
  },
  onPullDownRefresh: function() {
    // Do something when pull down.
  },
  onReachBottom: function() {
    // Do something when page reach bottom.
  },
  onShareAppMessage: function () {
   // return custom share data when user share.
  },
})
