if i press caps lock button nor not it gives me the message Capslock is on...,?

There's a blog post here ^[^] that claims to detect Caps Lock, but I haven't tried it.

Personally I like this solution[^] which just checks if the character entered is in Caps. If it is, and the ShiftKey is pressed, then Caps Lock is probably on

JavaScript

var s = String.fromCharCode(e.which);
 if ( s.toUpperCase() === s && s.toLowerCase() !== s && !e.shiftKey ) {
    alert('caps is on');
}

Hi,

there is an article here:
Detect Caps Lock with JavaScript[^]

Gook luck!
