jquery.cookie中的操作:

jquery.cookie.js是一个基于jquery的插件,点击下载

创建一个会话cookie:

$.cookie(‘cookieName’,'cookieValue’);

注:当没有指明cookie时间时,所创建的cookie有效期默认到用户浏览器关闭止,故被称为会话cookie。

创建一个持久cookie:

$.cookie(‘cookieName’,'cookieValue’,{expires:7});

注:当指明时间时,故称为持久cookie,并且有效时间为天。

创建一个持久并带有效路径的cookie:

$.cookie(‘cookieName’,'cookieValue’,{expires:7,path:’/'});

注:如果不设置有效路径,在默认情况下,只能在cookie设置当前页面读取该cookie,cookie的路径用于设置能够读取cookie的*目录。

创建一个持久并带有效路径和域名的cookie:

$.cookie(‘cookieName’,'cookieValue’,{expires:7,path:’/',domain: ‘chuhoo.com’,secure: false,raw:false});

注:domain:创建cookie所在网页所拥有的域名;secure:默认是false,如果为true,cookie的传输协议需为https;raw:默认为false,读取和写入时候自动进行编码和解码(使用encodeURIComponent编码,使用decodeURIComponent解码),关闭这个功能,请设置为true。

获取cookie:

$.cookie(‘cookieName’);   //如果存在则返回cookieValue,否则返回null。

删除cookie:

$.cookie(‘cookieName’,null);

注:如果想删除一个带有效路径的cookie,如下:$.cookie(‘cookieName’,null,{path:’/'});
