Jquery.cookie.js Use guide _jquery

Jquery.cookie.js is a lightweight cookie plugin that can read, write, and delete cookies.

Configuration of Jquery.cookie.js

First contains the library file for jquery, followed by the Jquery.cookie.js library file.

Copy Code code as follows:

<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

Add a new session cookie:

Copy Code code as follows:

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

Note: When a cookie is not valid, the creation of the cookie is not valid until the user closes the browser, and is called the session cookie. Create a cookie and set the valid time to 7 days:

Copy Code code as follows:

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

Note: When the cookie is valid, the cookie created is called the persistent cookie (persistent cookie). Create a cookie and set a valid path for the cookie:

Copy Code code as follows:

$.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 a page to read a cookie for another page setting, 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. Set this path to the root of the Web site so that all pages can read cookies to each other (typically do not set this up to prevent conflicts). Read cookies:

Copy Code code as follows:

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

Delete the cookie by passing null as the value of the cookie: $.cookie (' The_cookie ', null);

Explanation of related parameters

expires:365

Defines the valid time for a cookie, which can be a number (from the time the cookie was created, in days), or a date pair
Like. If omitted, the cookie created is a session cookie that will be deleted when the user exits the browser.

Path: '/'

By default: Only the Web page that sets the cookie can read the cookie.
Defines a valid path for a cookie. By default, the value of this parameter is the path of the Web page where the cookie was created (the behavior of the 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 cookie that defines a valid path, you need to include this path when calling the function: $.cookie (' The_cookie ', NULL,
{path: '/'});.

Domain: ' example.com '

Default: The domain name owned by the Web page that created the cookie. Secure:true
Default value: False. If the transport for True,cookie requires the use of security Protocol (HTTPS). Raw:true default value: False.
By default, encoding and decoding is automatically done when reading and writing cookies (using encodeURIComponent encoding,
decodeURIComponent decoding). To turn off this feature setting raw:true.
