Accessing functions bound to event handlers with jQuery

Question

With jQuery you can bind functions to an event triggered on a DOM object using .bind() or one of the event handler helper functions.

jQuery have to store this internally somehow and I wonder if is it possible given a DOM object, to find out which events have been bound to the object, and access those functions etc. The desired return result could look something like this:

{
  click: [function1, function2],
  change: [function3],
  blur: [function4, function5, function6]
}

Answer 1

You can find a lot of interesting tips and tricks in this article: Things you may not know about jQuery.

It seems that jQuery use data to store event handlers:

You can access all event handlers bound to an element (or any object) through jQuery’s event storage:

// List bound events:
console.dir( jQuery('#elem').data('events') );

// Log ALL handlers for ALL events:
jQuery.each($('#elem').data('events'), function(i, event){
    jQuery.each(event, function(i, handler){
        console.log( handler.toString() );
    });
});

// You can see the actual functions which will occur
// on certain events; great for debugging!
