e.stop(); works for me as well. What I am looking for is a way to kill all the events (never to fire again). Would help a lot to deal with app “crashes” when timers and mouse, etc. events are involved.

@Paul Schwarz: Another example is, you can have plugins on page that do something with your elements, and don’t have access to this functions. It can be more that one function connected to element, and from other sources than yours. So basically calling: myelement.fireEvent you will call all functions attached to the event, and you don’t have to remember or search for it.

@Paul Schwarz: Your solution require to remember what function is connected to event. Sometimes it’s anonymous functions and you can’t call it directly. Little example:

//add action to all links on page
$$(‘a’).addEvent(‘click’, function (e) {alert(‘My href is’+this.get(‘href’));});

$$(‘a’)[0].fireEvent(‘click’);

Granted you may have some special reason for fake-firing an event in which case your solution is fine. But more generally a better practise is to have your event handler call a function. So if you need to make that function happen, just call your function from code rather than faking the event and tripping the event handler in a fake way. Maybe you can give an example of when it’s not possible to use my suggestion?
Thanks,

I prefer the syntax, considering it saves a whole byte:
e && e.stop();

I do this all the time, it’s always nice to see other developers handling it the same way.

@David Walsh: Thanks, that’s good info. I hadn’t run into that as an issue, but will keep this in mind going forward.
