jQuery操作cookie的插件,大概的使用方法如下

$.cookie('the_cookie’); //读取Cookie值
$.cookie(’the_cookie’, ‘the_value’); //设置cookie的值
$.cookie(’the_cookie’, ‘the_value’, {expires: 7, path: ‘/’, domain: ‘jquery.com’, secure: true});//新建一个cookie 包括有效期路径域名等
$.cookie(’the_cookie’, ‘the_value’); //新建cookie
$.cookie(’the_cookie’, null); //删除一个cookie
