<script type= "Text/javascript" src= "Js/jquery-1.6.2.min.js" ></script>

<script type= "Text/javascript" src= "Js/jquery.cookie.js" ></script>

How to use

1. Add a new session cookie:

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

Note: When a cookie is not valid, the validity of the cookie is created by default until the user closes the browser, so it is called

"Session Cookie".

2. Create a cookie and set a valid time of 7 days:

$.cookie (' The_cookie ', ' The_value ', {expires:7});

Note: When the cookie is valid, the cookie created is called the persistent cookie (persistent cookie).

3. Create a cookie and set a valid path for the cookie:

$.cookie (' The_cookie ', ' The_value ', {expires:7, path: '/'});

Note: By default, only the Web page that sets the cookie can read the cookie. If you want one page to read another page set

Cookie, you must set the path of the cookie. The path to the cookie is used to set up a top-level directory that can read cookies. Will this

The path is set to the root of the Web site, allowing all pages to read cookies to each other (not normally set to prevent conflicts).

4. Read cookies:

$.cookie (' The_cookie '); Cookies exist => ' the_value '

$.cookie (' not_existing '); Cookie does not exist => null

5. Delete the cookie by passing null as the value of the cookie:

$.cookie (' The_cookie ', null);
