Question

What I need is to detect, whether the caps lock key at the very moment is down. So I don’t need the state (on/off), I want to check if the user keeps the caps lock pressed down. Is it possible with javascript? I want to create something like an Enso Launcher inside the browser.

Answer 1

I want to check if the user keeps the caps lock pressed down.

On most browsers, you’ll get keydown and keyup events for CapsLock, try it here (just focus the page and press a key). (This article has lots of useful info about keyboard events.)

keydown doesn’t seem to repeat for CapsLock, the way it does for others, but you can watch for keydown and assume it’s down until you see keyup.
