As far as i know there is no way to via javascript to find if the cap's lock is on, the only way i can think is to check when you get input if it's an upper or lower case.

So when something get's entered, check the data and get the ascii value of it.  If the letter is between a certain range then you can tell if it's upper or lower case, and if all the letters are upper they either have the shift key down or the cap's lock.

http://www.lookuptables.com for the numbers.

I've not tried this, but it may be worth a shot.  
(not my own work, I found it at:  http://www.rgagnon.com/pbdetails/pb-0236.html


[local function declaration]
FUNCTION  int GetKeyState(int keystatus) LIBRARY "user32.dll"

[powerscript]
int li_keystate

li_keystate = GetKeyState(20)

IF li_keystate = 1 THEN
    MessageBox("", "CAPS on")
ELSEIF li_keystate = 0 THEN
    MessageBox("", "CAPS off")
END IF

jsimbeck, that is not javascript and cannot be used for web development.

I will try to find something but, I would go with UnexplainedWays`s solution.
