Is there a standard way of programmatically firing an event on an
element? I think this code works in IE but not FF:
myElement.fireEvent(''onclick'');
I really only care about IE and FF, but anything else is a bonus. I
didn''t see anything in prototype/scriptaculous for this, but I might
have missed it. Thanks.

Just kind of shooting from the hip, but this *might* work: var func = myElement.onclick; func(); But it is Monday and I am tired :) Greg> -----Original Message----- > From: rails-spinoffs-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org[mailto:rails-spinoffs-> bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org] On Behalf Of Athman,Joseph J > Sent: Monday, June 12, 2006 8:52 AM > To: rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > Subject: [Rails-spinoffs] Cross Broswer Fire Event > > Is there a standard way of programmatically firing an event on an > element?

But I like my temp variable :) Yeah, it''s Monday.

That would only execute the function that is attached to the onclick event (if there is one), not actually cause the onclick event to fire. Also, if there was not function attached to the onclick event, that would cause an error. To actually fire the event and cause all event handlers to execute (whether they were attached inline or via the W3C model... use the event name (without the "on") as a function invocation... myElement.click(); ...I know this works for the click event, I''ve not tested it with the other events though.

Sorry, I assumed he meant he wanted to call the function attached to the onclick. Your solution works with click events, but there is no ''mouseover()'' function :-) Anyway, as I mentioned, I am tired, and it is Monday, so I wasn''t really sure I was answering the question correctly (waiting for the Mountain Dew to kick in...). Also, doing myform.submit() does not fire the onsubmit handler (I''m sure there''s a good reason, but I dunno what it is), so it isn''t a universal solution. But, yeah, if he wanted to trigger the chain of click events, he''d need to call the click() function.

I didn''t think about observers and other effects of event dispatching. In that case another thing to take a look at would be the unit testing library in script.aculo.us. It has some experimental functionality for simulating mouse events and key events: http://dev.rubyonrails.org/browser/spinoffs/scriptaculous/src/unittest.js?format=txt It''s right at the top of this file.

Thanks for the help. That testing mouse simulation stuff seems pretty useful, does anyone know if they plan on putting it into scriptaculous? I appreciate it.

What about the onchange event? It doesn''t look like there is a element.change() function. Thoughts?

It''s a great discussion on JS events. And yes,
element.fireEvent(''onclick''/etc) is IE 5.5+ centric.
~ Brice
I may have gotten this from Quirksmode. I''m not sure, but here is an
example I use in a JSUnit test:
//test with the onchange event
var changeEvent = document.createEvent(''HTMLEvents'');
changeEvent.initEvent( ''change'', true, true );
ti.value = ''4'';
ti.dispatchEvent(changeEvent);
