Why do you always call back to demo2commands!

how should I write this way?

Click the button.. Make a callback!

Mar.18,2021

var My = function(options){
    ...
}

var my1 = new My(...)
var my2 = new My(...)

your settings is a global variable, so naturally there is only one callback.

  1. pass the callback to shows_qr
  2. bind different callbacks, using upstairs methods, closures, or dictionaries.
