A simple, lightweight jQuery plugin for reading, writing and deleting cookies.


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

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


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 site:

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

Read cookie:

$.cookie('the_cookie'); // => "the_value"
$.cookie('the_cookie', { raw: true }); // => "the_value" not URL decoded
$.cookie('not_existing'); // => null

Delete cookie:

// returns false => No cookie found
// returns true  => A cookie was found
$.removeCookie('the_cookie'[, options]);

Note: when deleting a cookie, you must pass the exact same path, domain and secure options that were used to set the cookie, unless you're relying on the default options that is.


raw: true

By default the cookie value is encoded/decoded when creating/reading, using encodeURIComponent/decodeURIComponent. Turn off by setting raw: true. Default: false.

json: true

Automatically store JSON objects passed as the cookie value. Assumes JSON.stringifyand JSON.parse.

Cookie Options

Options can be set globally by setting properties of the $.cookie.defaults object or individually for each call to $.cookie() by passing a plain object to the options argument. Per-call options override the ones set by $.cookie.defaults.

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 becomes a session cookie.

path: '/'

Define the path where the 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 domain use path: '/'. Default: path of page where the cookie was created.

domain: ''

Define the domain where the cookie is valid. Default: domain of page where the cookie was created.

secure: true

If true, the cookie transmission requires a secure protocol (https). Default: false.
