知识点：

小程序公共对象（所有页面都可以调用此数据）
- app.js：
  
  小程序全局globalData（放公共数据所有页面都可以调用）
```
App({

  /**
   * 当小程序初始化完成时，会触发 onLaunch（全局只触发一次）
   */
  onLaunch: function () {

  },
  globalData:{
    userInfo: null, 
  }
})
```
  其他页面操作公共值app.js（app.globalData）
```
var app = getApp();

Page({
  data: {
    },
    onShow:function(){
      app.globalData
    }
});
```
  注意：修改globalData之后，其他页面以用的值不会自动变化，而是需要手动设置。

本地存储操作Storage

wx.getStorageSync('userInfo'); 
wx.setStorageSync('userInfo',"sdfsfd");
wx.removeStorageSync("userInfo")

页面调用栈

var pages = getCurrentPages();
prevPage = pages[pages.length-2];

跳转回上一个页面
```
wx.navigateBack({});
```
小程序页面的生命周期
- onLoad（一次）
- onShow（只要展示这个页面，就会自动加载）
- onReady（一次）
- onHide（每次页面隐藏就会自动加载，）
- onUnload（卸载页面，小程序关闭）

小程序代码：

全局app.js

App({

  /**
   * 当小程序初始化完成时，会触发 onLaunch（全局只触发一次）
   */
  onLaunch: function () {

  },
  globalData:{
    userInfo: null, 
  }
})
