## Installation
Include script *after* the jQuery library (unless you are packaging scripts somehow else):
```html
<script src="/path/to/jquery.cookie.js"></script>
```
## Usage
Create session cookie:
```javascript
$.cookie(‘the_cookie‘, ‘the_value‘);
```
Create expiring cookie, 7 days from then:
```javascript
$.cookie(‘the_cookie‘, ‘the_value‘, { expires: 7 });
```
Create expiring cookie, valid across entire site:
```javascript
$.cookie(‘the_cookie‘, ‘the_value‘, { expires: 7, path: ‘/‘ });
```
Read cookie:
```javascript
$.cookie(‘the_cookie‘); // => "the_value" $.cookie(‘not_existing‘); // => undefined
```
Read all available cookies:
```javascript
$.cookie(); // => { "the_cookie": "the_value", "...remaining": "cookies" }
```
Delete cookie:
```javascript
// Returns true when cookie was found, false when no cookie was found...
$.removeCookie(‘the_cookie‘);
// Same path as when the cookie was written...
$.removeCookie(‘the_cookie‘, { path: ‘/‘ });
```
*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.*
## Configuration
### raw
By default the cookie value is encoded/decoded when writing/reading, using `encodeURIComponent`/`decodeURIComponent`. Bypass this by setting raw to true:
```javascript $.cookie.raw = true; ```
### json
Turn on automatic storage of JSON objects passed as the cookie value. Assumes `JSON.stringify` and `JSON.parse`:
```javascript $.cookie.json = true; ```
## Cookie Options
Cookie attributes can be set globally by setting properties of the `$.cookie.defaults` object or individually for each call to `$.cookie()` by passing a plain object to the options argument. Per-call options override the default options.
### expires
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
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.
**Note regarding Internet Explorer:**
> Due to an obscure bug in the underlying WinINET InternetGetCookie implementation, IE’s document.cookie will not return a cookie if it was set with a path attribute containing a filename.
(From [Internet Explorer Cookie Internals (FAQ)](http://blogs.msdn.com/b/ieinternals/archive/2009/08/20/wininet-ie-cookie-internals-faq.aspx))
This means one cannot set a path using `path: window.location.pathname` in case such pathname contains a filename like so: `/check.html` (or at least, such cookie cannot be read correctly).
### domain
domain: ‘example.com‘
Define the domain where the cookie is valid. Default: domain of page where the cookie was created.
### secure
secure: true
If true, the cookie transmission requires a secure protocol (https). Default: `false`.
## Converters
Provide a conversion function as optional last argument for reading, in order to change the cookie‘s value to a different representation on the fly.
Example for parsing a value into a number:
```javascript $.cookie(‘foo‘, ‘42‘); $.cookie(‘foo‘, Number); // => 42 ```
Dealing with cookies that have been encoded using `escape` (3rd party cookies):
```javascript $.cookie.raw = true; $.cookie(‘foo‘, unescape); ```
You can pass an arbitrary conversion function.
