I need to find which event handlers are registered over an object.
For example:
$("#el").click(function() {...});
$("#el").mouseover(function() {...});
$("#el") has click and mouseover registered.
Is there a function to find out that, and possibly iterate over the event handlers?
If it is not possible on a jQuery object through proper methods, is it possible on a plain DOM object?
For jQuery 1.8+, this will no longer work because the internal data is placed in a different object.
The latest unofficial (but works in previous versions as well, at least in 1.7.2) way of doing it now is -
$._data(element, "events")
The underscore ("_") is what makes the difference here. Internally, it is calling $.data(element, name, null, true), the last (fourth) parameter is an internal one ("pvt").
Events can be retrieved using:
jQuery(elem).data('events');
or jQuery 1.8+:
jQuery._data(elem, 'events');
Note:
Events bounded using $('selector').live('event', handler)
can be retrieved using:
jQuery(document).data('events')
