756096 - keyCode is always 0 on keydown and keyup when typing in Thai language.

Status: RESOLVED DUPLICATE of bug 677252

(Firefox :: Untriaged, defect)

Description

[Thai Pangsakulyanont]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:12.0) Gecko/20100101 Firefox/12.0
Build ID: 20120420145725

Steps to reproduce:

With Thai keyboard layout, press a key that types a Thai character and triggers the keyup->keypress->keydown DOM event.

- Go to http://unixpapa.com/js/testkey.html
- Switch to Thai keyboard layout.
- Press a key, for example "ก", which corresponds to the "D" key.


Actual results:

The keyCode turns out to be 0. Firefox on Mac reports:

keydown  keyCode=0         which=0         charCode=0        
keypress keyCode=0         which=3585      charCode=3585     
keyup    keyCode=0         which=0         charCode=0    


Expected results:

The physical key that is being pressed should be reported. Here is the result on Chrome for Mac:

keydown  keyCode=68  (D)   which=68  (D)   charCode=0        
keypress keyCode=3585      which=3585      charCode=3585     
keyup    keyCode=68  (D)   which=68  (D)   charCode=0        

Note that Firefox on Windows doesn't have this issue and should have the same output.

I think I see a similar bug here. My keyboard is not Thai, it's Italian.
When I type Italian characters, like àèéìòù, I get keyCode=0.

Steps to reproduce:
- Switch to Italian layout (mine is an extended keyboard, with shord left shift key)
- Go to http://unixpapa.com/js/testkey.html
- press a key with grave accent (for example, any of 3 keys between L and ENTER)

Actual result:
keydown  keyCode=0         which=0         charCode=0
keypress keyCode=0         which=249       charCode=249
keyup    keyCode=0         which=0         charCode=0

Expected result (copied from execution on Chrome):
keydown  keyCode=191       which=191       charCode=0
keypress keyCode=249       which=249       charCode=249
keyup    keyCode=191       which=191       charCode=0
