Javascript cookie delete

Question

If I create a cookie in Javascript document.cookie = \'unseen\' how do I delete it when I navigate away from this page? This is the only cookie I am creating on the

Answer 1

Sometimes

document.cookie = 'unseen=; expires=Thu, 01-Jan-70 00:00:01 GMT;';

but sometimes need to specify path, if the first one failed (not the case of your exact code)

document.cookie = 'unseen=; expires=Thu, 01-Jan-70 00:00:01 GMT; path=/';

(or use the same library function for creating cookie, but set negative number instead of positive expiry time)
