To detect if the caps lock is on, use the getModifierState()
method for the KeyboardEvent object:
const capslockIsOn = event.getModifierState(modifier);
The getModifierState()
method returns true
if a modifier is active; else, it returns false
. So, event.getModifierState('CapsLock')
can be used to detect if the caps lock is on.
The following snippet is example to detect if the caps lock is on.
