How to find event handlers on an object in jQuery 1.8+?
var func = function(){ alert(1); };
var obj = $('#obj');
obj.on("click", func);
// obj.data('events') is undefined
Use the data function as is done by jQuery internally.
On previous versions, you could call it like for other data :
obj.data('events');
In jQuery 1.8, this direct access was removed, so in recent versions you must call it like this :
$._data(obj[0], "events")
You can see it in action by opening the console in this fiddle : http://jsfiddle.net/8TpeP/2/
to find event handlers of an element in jQuery 1.8+ you've got to do this way:
$._data($("YOUR-SELECTOR-HERE").get(0), "events")
