The library file for jQuery is included first, followed by the library file for jquery.cookie.js.

Usage

1. Add a new session cookie:

$.cookie ('the_cookie',' the_value')

Note: when the cookie validity period is not specified, the created cookie is valid by default until the user closes the browser, so it is called

Session cookie (session cookie).

two。 Create a cookie and set the validity period to 7 days:

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

Note: when the cookie validity time is specified, the cookie created is called "persistent cookie (persistent cookie)".

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

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

Note: by default, only web pages that set the cookie can read the cookie. If you want one page to read another page setting

To set the cookie, you must set the path of the cookie. The path to cookie is used to set the top-level directory that can read cookie. Put this

The path is set to the root directory of the site, so that all pages can read cookie from each other (generally do not set this to prevent conflicts).

4. Read cookie:

$.cookie ('the_cookie'); / / cookie exists = >' the_value' $.cookie ('not_existing'); / / cookie does not exist = > null

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

$.cookie ('the_cookie', null)

2). Path:'/'

Default: only web pages that set the cookie can read the cookie.

Define a valid path to the cookie. By default, the value of this parameter is the path of the web page that created the cookie (the behavior of a standard browser).

If you want to access this cookie throughout the site, you need to set a valid path: path:'/'. If you want to delete a definition

The cookie of a valid path, which you need to include when calling the function: $.cookie ('the_cookie', null

{path:'/'});. Domain: 'example.com'

Default value: the domain name owned by the web page that created cookie.

3) .secure: true

Default value: false. If the transport for true,cookie requires the use of Security Protocol (HTTPS).
