Question

Whenever I do :

$.ajax({
  //my settings
}).done(function(data){
  // Publish or store data
});

It works perfectly fine! however, I’m trying to apply the observer pattern, because I’m required to, but when I do, using this code:

$.ajax({
  // my settings
}).done(function(data){
  $(document).trigger('ALLREADY',data);
});

// Some other part of the code
$(document).on('ALLREADY',function(e,data){
  console.log(data); // WHY?!
});

The response (data) is only storing the first value, not the whole array, as it does with the first example, what did i do to break the functionality?

PS: Note that even though it’s returning only the first value of a supposedly big array, even when i try to use it, it won’t let me, however, i can log it.

Since data is an array, each individual piece is sent as a separate argument in the event callback. It’s strange because if data were an object this would not be the case (you’d be able to use it like data).

Instead, just use data = arguments.slice(1)
