$.cookie('the_cookie', 'the_value'); // 设置cookie
$.cookie('the_cookie', 'the_value', { expires: 7 }); //设置带时间的cookie
$.cookie('the_cookie', 'the_value', { expires: 7, path: '/', domain: 'sosuo8.com', secure: true });
$.cookie('the_cookie', '', { expires: -1 }); // 删除
$.cookie('the_cookie', null); // 删除 cookie
