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);
Options
expires: 365
Define lifetime of the cookie. Value can be a Number (which will be interpreted as days from time
of creation) or a Date object. If omitted, the cookie is a session cookie.
path: '/'
Default: path of page where the cookie was created.
Define the path where cookie is valid. By default the path of the cookie is the path of the page where
the cookie was created (standard browser behavior). If you want to make it available for instance across the entire page use path:
'/'. If you want to delete a cookie with a particular path, you need to include that path in the call.
domain: 'example.com'
Default: domain of page where the cookie was created.
secure: true
Default: false. If true, the cookie transmission requires a secure protocol (https).
raw: true
Default: false.
By default the cookie is encoded/decoded when creating/reading, using encodeURIComponent/decodeURIComponent.
Turn off by setting raw: true.
