设置Cookie过期日期-Javascript

Question

I was trying to create a cookie with a defined expiration date. Here's my code:

function setCookie(){
  var date=new Date();
  date.setFullYear(2015);
  document.cookie="cookie_name=tracking_true; expires=" +date.toUTCString() + ";";
}

When I check into my browser (from Google Chrome console I type: document.cookie), I can find only this: cookie_name=tracking_true. I cannot find the expires date. Do you have any idea why I cannot see the exiperes date?

Thanks, Alessio

document.cookie displays only the cookie names. To see other parameters, in Chrome, use developer tools, resources tab, then cookies. In Firebug, use the cookies tab. There is documentation here: https://developer.mozilla.org/en-US/docs/Web/API/document.cookie
