使用方法简介：

创建 session cookie（浏览器关闭后删除）:

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

 

创建指定过期时间的cookie，7天后过期:

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

创建7天后会过期的cookie，cookie对整个网站有效：

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

读取cookie

$.cookie('the_cookie'); // => "the_value"
$.cookie('not_existing'); // => undefined

读取所有cookie：

$.cookie(); // => { "the_cookie": "the_value", "...remaining": "cookies" }

删除cookie：

// Returns true when cookie was found, false when no cookie was found...
$.removeCookie('the_cookie');

// Same path as when the cookie was written...
$.removeCookie('the_cookie', { path: '/' });
