I need to select all elements, that has binded \"click\" event? Is there such selector exists?
It is not supported natively by jQuery, but you can write your own custom selector using hasEvent plugin :
jQuery.expr[":"].click = "jQuery(a).hasEvent('click');";
$("a:click").doStuff();
EDIT :
There is also the Event Bound Selector plugin which is more complete and works out of the box, but is also bigger.
