cookie 读取/操作不需要 jQuery，所以不要使用下面的原始答案.

jQuery isn't needed for cookie reading/manipulation, so don't use the original answer below.

转到https://github.com/js-cookie/js-cookie 而是使用不依赖于 jQuery 的库.

Go to https://github.com/js-cookie/js-cookie instead, and use the library there that doesn't depend on jQuery.

基本示例:

// Set a cookie
Cookies.set('name', 'value');

// Read the cookie
Cookies.get('name') => // => 'value'

有关详细信息，请参阅 github 上的文档.

See the docs on github for details.

查看插件:

https://github.com/carhartl/jquery-cookie

然后你可以这样做:

$.cookie("test", 1);

删除:

$.removeCookie("test");

此外，要在 cookie 上设置一定天数(此处为 10 天)的超时:

Additionally, to set a timeout of a certain number of days (10 here) on the cookie:

$.cookie("test", 1, { expires : 10 });

如果省略 expires 选项，则该 cookie 将成为会话 cookie，并在浏览器退出时被删除.

If the expires option is omitted, then the cookie becomes a session cookie and is deleted when the browser exits.

涵盖所有选项:

$.cookie("test", 1, {
   expires : 10,           // Expires in 10 days

   path    : '/',          // The value of the path attribute of the cookie
                           // (Default: path of page that created the cookie).

   domain  : 'jquery.com', // The value of the domain attribute of the cookie
                           // (Default: domain of page that created the cookie).

   secure  : true          // If set to true the secure attribute of the cookie
                           // will be set and the cookie transmission will
                           // require a secure protocol (defaults to false).
});

读回cookie的值:

To read back the value of the cookie:

var cookieValue = $.cookie("test");

更新(2015 年 4 月):

如下面的评论所述，开发原始插件的团队已在新项目中删除了 jQuery 依赖项 (https://github.com/js-cookie/js-cookie) 与 jQuery 版本具有相同的功能和通用语法.显然，原始插件不会随处可见.

As stated in the comments below, the team that worked on the original plugin has removed the jQuery dependency in a new project (https://github.com/js-cookie/js-cookie) which has the same functionality and general syntax as the jQuery version. Apparently the original plugin isn't going anywhere though.
