$._data($element[0], 'events');
will return all event handlers
$._data($element[0]);
will return all jQuery data (set by $(element).data(key, value)) and event handlers (set by $(element).on(eventName, handler)) for this element
Example in Chrome's console:
Object {events: Object, handle: function, data: Object}
- data: Object
uiProgressIndicator: $.(anonymous function).(anonymous function)
__proto__: Object - events: Object
click: Array[3]
remove: Array[1]
__proto__: Object - handle: function ( e ) {
arguments: null
caller: null
elem: body
length: 1
name: ""
prototype: Object
__proto__: function Empty() {}
<function scope> - __proto__: Object
We can see data for jQuery UI widget named 'progressIndicator' and four event handlers (three for 'click', one for 'remove' event) attached to the body of the HTML document.
Also Chrome has built-in command getEventListeners to show DOM event handlers attached to element:
> getEventListeners(document.body)
Object {click: Array[1], remove: Array[1]}
- click: Array[1]
- remove: Array[1]
- __proto__: Object
