Caps-lock is an extremely simple yet useful jQuery plugin that provides Caps lock notification for password fields. In this post, we're going to use Bootstrap Msg plugin to display an alert message when the visitor presses Caps Lock key.

How to use it:

1. Include the Bootstrap Msg plugin on your webpage. Make sure you first have jQuery and Bootstrap framework installed.

<link rel="stylesheet" href="bootstrap-msg-0.4.0.min.css">
<script src="bootstrap-msg-0.4.0.min.js"></script>

2. Caps lock check for password field.

$( "input[ type='password' ]" ).keypress( function(e) {
  var key_check = e.which;
  var isUp = ( key_check >= 65 && key_check <= 90 ) ? true : false;
  var isLow = ( key_check >= 97 && key_check <= 122 ) ? true : false;
  var isShift = ( e.shiftKey ) ? e.shiftKey : ( ( key_check == 16 ) ? true : false );
  if ( ( isUp && !isShift ) || ( isLow && isShift ) ) {
    capLock();
  };
});

3. If caps lock is on, show an alert.

Msg.show('Caps-lock is On!', 'warning', 5000);
