1.$.cookie (CookieName, cookievalue); CookieName: The cookie name to be set, Cookievalue represents the corresponding value.



Note: When a cookie is specified, the cookie created is referred to as a "persistent cookie (persistent cookie)".

3.$.cookie (' The_cookie ', ' The_value ', {expires:7, path: '/'}); Create a cookie and set a valid path for the cookie:



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