[Proto-Scripty] Re: callback decoration

[Eric]

Hi Sergio,

I am not sure what you mean by make the bind but here is an example
doing what you ask using ajax responders:

Ajax.Responders.register({
  onCreate: function(ar)
  {
ar.options.onSuccess = ar.options.onSuccess ||
Prototype.emptyFunction;

ar.options.onSuccess = ar.options.onSuccess.wrap(function
(localCB,xhr,xjs)
{
  // Do your stuffs here
  alert(Apex inboud!);

  // Then call the provided callback
  localCB(xhr,xjs);
});
  }
});

new Ajax.Request('http://jsbin.com/azeyo',{
  onSuccess: function(xr) { alert(CB:+xr.responseText); }
});


You can see it working here: http://jsbin.com/afudi and play with the
code here: http://jsbin.com/afudi/edit

Using Ajax.Request(), I forgot to say it, sorry.

 In a experiment, I'm trying to decorate the callbacks, but I didn't
 find the way to make the bind...

 What I'd like to do is to firstly get the control over response's
 callback, do some common stuff, and then invoke the callback set by
 the user.

 Anyone has any idea how can I do something like that?

 Thanks in advance.

 Best
