Installation

Include script after the jQuery library (unless you are packaging scripts somehow else):

<script src="/path/to/jquery.cookie.js"></script>

Usage

Create session cookie:

$.cookie('the_cookie', 'the_value');

Create expiring cookie, 7 days from then:

$.cookie('the_cookie', 'the_value', { expires: 7 });

Create expiring cookie, valid across entire page:

$.cookie('the_cookie', 'the_value', { expires: 7, path: '/' });

Read cookie:

$.cookie('the_cookie'); // => 'the_value'
$.cookie('not_existing'); // => null

Delete cookie by passing null as value:

$.cookie('the_cookie', null);
