KeyboardEvent: keyCode property
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
The deprecated KeyboardEvent.keyCode
read-only property represents a system and implementation dependent numerical code identifying the unmodified value of the pressed key.
This is usually the decimal ASCII (RFC 20) or Windows 1252 code corresponding to the key. If the key can't be identified, this value is 0
.
You should avoid using this if possible; it's been deprecated for some time. Instead, you should use KeyboardEvent.code
(for the physical key pressed) or KeyboardEvent.key
(for the character the key maps to). Check compatibility for either property if you target very old browsers.
Note: Web developers shouldn't use the keyCode
attribute for printable characters when handling keydown
and keyup
events. As described above, the keyCode
attribute is not useful for printable characters, especially those input with the Shift or Alt key pressed.
Value of keyCode
Printable keys in standard position
The value of key events which are caused by pressing or releasing printable keys in standard position is not compatible between browsers.
IE just exposes the native virtual keycode value as KeyboardEvent.keyCode
.
Google Chrome, Chromium and Safari must decide the value from the input character. If the inputting character can be inputted with the US keyboard layout, they use the keyCode
value on the US keyboard layout.
Firefox gets keyCode
values from ASCII characters inputtable by the key — even with shift modifiers or an ASCII capable keyboard layout. See the following rules for details:
- If the system is Windows and the native keycode of the pressed key indicates that the key is a-z or 0-9, use a keycode for it.
- If the system is Mac and the native keycode of the pressed key indicates that the key is 0-9, use a keycode for it.
- If the pressed key inputs an ASCII alphabetic or numeric character with no modifier key, use a keycode for it.
- If the pressed key inputs an ASCII alphabetic or numeric character with a Shift key modifier, use a keycode for it.
- If the pressed key inputs a different ASCII character with no modifier key, use a keycode for it.
- If the pressed key inputs a different ASCII character with a Shift key modifier, use a keycode for it.
- Otherwise, i.e., pressed key inputs a unicode character:
- If the keyboard layout is ASCII-capable (i.e., can input ASCII alphabets), use 0 or compute with the following additional rules.
- Otherwise, i.e., the keyboard layout isn't ASCII capable, use the ASCII capable keyboard layout installed on the environment with the highest priority:
- If the pressed key on the alternative keyboard layout inputs an ASCII alphabetic or numeric character, use a keycode for it.
- Otherwise, use 0 or compute with the following additional rules.
Gecko sets keyCode
values of punctuation keys as far as possible (when points 7.1 or 7.2 in the above list are reached) with the following rules:
Warning: The purpose of these new additional rules is for making users whose keyboard layouts map unicode characters to punctuation keys in a US keyboard layout can use web applications which support Firefox only with ASCII-capable keyboard layouts or just with a US keyboard layout. Otherwise, the newly mapped keyCode
values may be conflict with other keys. For example, if the active keyboard layout is Russian, the keyCode
value of both the "Period"
key and "Slash"
key are 190
(KeyEvent.DOM_VK_PERIOD
). If you need to distinguish those keys but you don't want to support all keyboard layouts in the world by yourself, you should probably use KeyboardEvent.code
.
- If running macOS or Linux:
- If the active keyboard layout is not ASCII-capable and an alternative ASCII-capable keyboard layout is available.
- If the alternative ASCII-capable keyboard layout produces an ASCII character via just the unmodified key, use a
keyCode
for the character. - If the alternative ASCII-capable keyboard layout produces an ASCII character with a Shift key modifier, use a
keyCode
for the shifted character. - Otherwise, use a
keyCode
for an ASCII character produced by the key when the US keyboard layout is active.
- If the alternative ASCII-capable keyboard layout produces an ASCII character via just the unmodified key, use a
- Otherwise, use a
keyCode
for an ASCII character produced by the key when the US keyboard layout is active.
- If the active keyboard layout is not ASCII-capable and an alternative ASCII-capable keyboard layout is available.
- If running on Windows:
- Use a
keyCode
value for an ASCII character produced by a key which is mapped to the same virtual keycode of Windows when the US keyboard layout is active.
- Use a

[2] On Mac, the Help key is mapped to the Insert key of PC keyboards. These keyCode
values are the same as the Insert key's keyCode
values.
[3] Tested on Fedora 20.
[4] Only a keyup
event is fired.
[5] PC's PrintScreen, ScrollLock and Pause are mapped to Mac's F13, F14 and F15, respectively. Chrome and Safari map them to the same keyCode
values as Mac's keys.
[6] Pause key with Control generates 0x03 (3)

keysyms. If the keys cause proper keysyms, these values must be same as IE.
[4] Tested on Fedora 20. The keys don't cause DOM key events on Chromium.
[5] The keyCode
value of a keyUp
event is 0x83 (131)
.
[6] Tested on Fedora 20. The keys don't cause DOM key events on Firefox.
[7] Only the keydown
event is fired.
[8] No DOM key events are fired on Firefox.

OEM specific keys on Windows
On Windows, some values of virtual keycode are defined (reserved) for OEM specific key. They are available for special keys on non-standard keyboard. In other words, some values are used for different meaning by two or more vendors (or hardware).
Starting Gecko 21 (and older than 15), OEM specific key values are available on the keyCode attribute only on Windows. So they are not useful for usual web applications. They are useful only for intranet applications or in similar situations.
See "Manufacturer-specific Virtual-Key Codes (Windows CE 5.0)" in MSDN for the detail.
