194403 - onchange event-handler in <select> works if you use the mouse to change, not if you use the arrow keys

Status: RESOLVED DUPLICATE of bug 126379

(Core :: DOM: Events, defect)

Description

[bugzilla]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3b) Gecko/20030210
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3b) Gecko/20030210

If you've got a <select> and use the onchange event handler, it only fires the
event by using the mouse to change the selected option, not if you use for
example the arrow keys.

Reproducible: Always

Steps to Reproduce:
1.Make a <select> with 2 options and onchange="alert('blablabla');" (of course
in a valid html-construct with head and body ;) )
2.Open the file

Actual Results:  
mozilla did show me the alert fenster by selecting an option with the mouse, not
wby changing with the arrow keys.

Expected Results:  
it should show the alert-window by changing the selected option. like you're
changing the selected option with the mouse ;D
