One way to specify a callback is by embedding a function within another function. This can be accomplished in JavaScript ES

A.file

function Carousel(){

  ~~~~~~ code ~~~~~~

  this.add = function(data){   
    do_something()
    self.addCallback.call(this, arguments)
  };

  this.remove = function(data){
    do_something()
    this.removeCallback.call(this, arguments)
  };

  ~~~~~~ code ~~~~~~    
}

Carousel.prototype.addCallback = function(){};
Carousel.prototype.removeCallback = function(){};

B.file

carousel = new Carousel();

carousel.addCallback = (function(data){

// I want the data from A.file, but i can't ! heeeeeelp~

  do_something(data)
  carousel.addCallback()
  do_something(data)
})();

The issue lies in retrieving the data from A.file in B.file. In my scenario, I require adding some callbacks after creating or removing actions. Is this approach correct? Could anyone provide additional tips, techniques, or corrections to the above problem? Any insights would be greatly appreciated.

Answer №1

I discovered a resolution.

Document A

function Carousel(){

  this.add = function(data){   
    do_something()
    self.addCallback.call(this, data)
  };
}

Carousel.prototype.addCallback = function(){};

Document B

carousel = new Carousel();

carousel.addCallback = function(data){

  do_bbb_things(data)
};

Subsequently running carousel.add('abc'), will trigger the execution of do_bbb_things('abc') afterwards.
