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 at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
The 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 or Windows 1252 code corresponding to the key. If the key can't be identified, this value is 0. The value of keypress event is different between browsers.
IE and Google Chrome set the value. Gecko sets 0 if the pressed key is a printable key, otherwise it sets the same keyCode as a keydown or keyup event. You should avoid using this if possible; it's been deprecated for some time. Instead, you should use, if it's implemented.
Unfortunately, some browsers still don't have it, so you'll have to be careful to make sure you use one which is supported on all target browsers. Google Chrome and Safari have implemented, which was defined in a draft specification but not the final spec.

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. Starting in Firefox 15 (Firefox 15.0 / Thunderbird 15.0 / SeaMonkey 2.12), Gecko 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. 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.
Starting in Firefox 60 (Firefox 60.0 / Thunderbird 60.0 / SeaMonkey 2.57), 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.
