USAGE:
Add 'klimit-*' to class attribute of input[type='text'] element
which you want to limit key input. Just like this:
<input type='text' name='number' class='klimit-digit' />
Pre-defined 'klimit-*' classes are:
- klimit-digit
- klimit-hex
- klimit-lower
- klimit-upper
- klimit-alpha
- klimit-alnum
- klimit-graph
- klimit-mail
You can also make your custom rule. For instance, if you want allow
user to input only alphabets, numbers, dot(.) and underscore(_)
as username, this will be done with:
HTML
<input type='type' name='username' id='username' />
jQuery
$('input#username').klimit([$.KLIMIT.ALNUM, '._']);
NOTE:
The key code map to convert a character into key code (event.keyCode)
is based on 101 US keyboard layout by default. If you want to alter
some of key codes, assign key code map to jQuery.KLIMIT.KEY_CODE_MAP
prior to jquery.klimit.js is loaded.
This plugin also provides 'jquery.klimit.kb109.js' which defines
key codes for 106/109 Japanese keyboard as an example. So if you
work with 106/109 Japanese keyboard, you should implement your HTML
as below:
<script src='jquery.js'></script>
<script src='jquery.klimit.kb109.js'></script>
<script src='jquery.klimit.js'></script>
