get the value of app.globalData in user.js , 

 

 Thank you for the invitation. I was busy yesterday and didn't reply in time. The 
 code is not posted enough. At least post your login functions and operation variables. Looking at this picture, I can only outline my analysis 
.

    

  •  first of all, the data used for rendering in wxml must be the corresponding value in the data object in js before initializing rendering 
    • 

  •  after dynamically modifying the value of app.globalData.isLogin, you must use the setData method in user.js to re-render. It is invalid to modify data directly 
    • .

  •  deal with asynchronous problems
