    Hello Reader's, If want to make alert when the upper/lower case letter key is pressed. Then by using Javascript you can see it in the code below:-

    $('#cap').keypress(function(e) { 
    var s = String.fromCharCode( e.which );
    if ( s.toUpperCase() === s && s.toLowerCase() !== s && !e.shiftKey ) {
        alert('caps key is on');
    }
});
    Javascript
