Jquery. Basic usage of Cookie Plug-ins

Basic usage of Jquery.cookie:

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 (' name ', ' value ');

Create expiring cookies, 7 days from then:

$.cookie (' name ', ' value ', {expires:7});

Create expiring cookies, valid across entire site:

$.cookie (' name ', ' value ', {expires:7, path: '} ');
Read Cookie:

$.cookie (' name '); => "Value"
$.cookie (' nothing '); => undefined

Read All available cookies:

$.cookie (); => {"Name": "Value"}

Delete Cookie:

Returns True when Cookie is successfully deleted, otherwise false
$.removecookie (' name '); => true
$.removecookie (' nothing '); => false

Need to use the same attributes (path, domain) as what the cookie is written with
$.cookie (' name ', ' value ', {path: '/'});
This won ' t work!
$.removecookie (' name '); => false
This would work!
$.removecookie (' name ', {path: '/'}); => true
