Keyboard_code
when you want to identify a key that the user pressed. This should
be invoked for keydown and keyup events, not keypress events.
If the browser supports the standardized key
and code
properties, then of_event
on a keypress event will have the correct behavior. Otherwise, it might not identify
or might mis-identify which key was pressed. This occurs because the keypress event is
designed for printable characters while keydown and keyup are designed for physical
keys. Thus, the older properties of keyEvent
change behavior between keydown and
keypress events. This change in behavior is what causes the mapping to be incorrect.
