Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[Guang]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20051109 Firefox/1.6a1

I register a mousedown event of an anchor, and after I click the anchor, the keyCode I get is "undefined", which was "0" in older version of firefox and other browsers.

ex:
eventHandler(e){
	if (isIE){
	   return;
	} else {
	   alert(e.keyCode)
	   return;		
	}
 }

Reproducible: Always

Steps to Reproduce:
1.register the mousedown
2.fire the mouse down event
3.alert value is "undefined" which should be "0"

Actual Results:  
get an unwanted keyCode value "undefined"


some script function use keyCode==0 to test if it is a mouse event
so if the return value is "undefined", 
the functions won't work well

This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME
