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.

IN 2019, this is now possible:

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

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 =/
