How to trigger events on all elements

Question

I want to use custom events in my J-Query website. Now I'm not sure which one is the best way to trigger a custom event on all elements attached to this event.

An example could be more clarifying here: Basically I could use

$('#id').trigger('customevent');

I don't want the triggering element to have to know all elements attached to the event. So I could use

$('*').trigger('customevent');

which would hopefully do what I want. But I'm afraid that this way has some performance issues.

Another way I was thinking about is using a class. All elements attached to the event could add this class to themselves. Then I can use this class as selector. However, all this smells like workaround.

I really hope that somebody knows an usual way to solve my problem.

Just found the answer by myself (which is now deprecated, see comment below):

$.event.trigger('customevent');
