Check Scroll Lock, Num Lock & Caps Lock in JavaScript on Page Load

StackOverflow https://stackoverflow.com/questions/9060090

Question

Is it possible to check the status of Scroll Lock, Num Lock and Caps Lock on page load of a web page? I've found ways to check after a keypress using JavaScript, but that's not what I'm asking.

Was it helpful?

Solution

No, you can't get system state from javascript. You will need them to type something and then analyze the input. Probably not what you wanted to hear =/

OTHER TIPS

IN 2019, this is now possible: 

var x = event.getModifierState("ScrollLock");
