下载地址：https://github.com/carhartl/jquery-cookie
jquery.cookie使用方法：
创建 临时cookie:
$.cookie(\'name\', \'value\');
创建有效时间期限为7天的 cookie:
$.cookie(\'name\', \'value\', { expires: 7 });
创建有效期限为7天并带路径的 cookie:
$.cookie(\'name\', \'value\', { expires: 7, path: \'/\' });
读取 cookie:
$.cookie(\'name\'); // => "value"
$.cookie(\'nothing\'); // => undefined
读取浏览器中所有的 cookies:
$.cookie(); // => { "name": "value" }
删除 cookie:
// Returns true when cookie was successfully deleted, otherwise false
$.removeCookie(\'name\'); // => true
$.removeCookie(\'nothing\'); // => false
// Need to use the same attributes (path, domain) as what the cookie was written with
$.cookie(\'name\', \'value\', { path: \'/\' });
// This won\'t work!
$.removeCookie(\'name\'); // => false
// This will work!
$.removeCookie(\'name\', { path: \'/\' }); // => true
Note: when deleting a cookie, you must pass the exact same path, domain and secure options that were used to set the cookie, unless you\'re relying on the default options that is. 这段话自己翻译
