Wechat applet development - Page jump pass parameters

---

There are four ways of page Jump , Respectively wx.navigateTo、wx.redirectTo、wx.reLaunch、wx.switchTab, The first three can be passed url The path carries parameters to realize parameter transfer , Such as

wx.navigateTo({
    
        url: '/pages/detail/detail?info='+info
      })

And by wx.switchTab Jump to tabBar When the page is , Parameters cannot be passed in the above way , There are two solutions ：
The first one is , adopt app.js Global variables pass parameters

//app.js in 
globalData: {
    
    info:null,
    userInfo: null
  }
// On the page where parameters are passed js In file 
const app=getApp()  
app.globalData.info="info"
// On the page receiving parameters js In file 
const app=getApp()  
console.log(' adopt app.js Global variables pass parameters ',app.globalData.info)

The second kind , Pass parameters through cache

// In the page file that passes parameters js in 
wx.setStorageSync('info', info)
// In the page file that receives parameters js in 
console.log(' Pass parameters through cache ',wx.getStorageSync('info'))
