【jQuery】Jquery.cookie()

 注意：如果不设置path，默认为当前路径，新建cookie

 $.cookie('name', 'value');

 新建带限制时间cookie
 $.cookie('name', 'value', { expires: 7 });
 新建限制时间和路径cookie，
 $.cookie('name', 'value', { expires: 7, path: '/' });

 读取cookie
 $.cookie('name'); // => "value"
 $.cookie('nothing'); // => undefined

 读取所有可用cookie$.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
