Ajax callbacks in rails3

Question

In rails 2 for a ajax form we can have ajax callbacks like before, after etc. How to do it in rails 3.

Answer 1

I'm having the same problem, and this post helped me figure it out. Basically you need to attach a listener to the element that reacts on rails' callback events. For example:

<%= link_to 'Delete', post, 
  :confirm => 'Are you sure?', 
  :method => :delete, 
  :remote=>true, 
  :id=>'delete' %>

In a separate js file (to make it unobtrusive), with jQuery:

$('#delete').bind('ajax:success', function() {
  // do something
});

Answer 2

Binding a function to ajax:success as morbaq suggested worked for me.

However, I think if there is more than one ajax behavior associated with the element, the function will run for each of them.
