For example, there is a cookie like this:

Change the user name to "JavaScript" and set it to expire one day later:

Var date=new Date ()

Var cookieExpire=date.getTime () + 24036001000

/ / when modifying cookie, the name, path and domain name must be the same

[xss_clean] = "username=JavaScript; expire=" + cookieExpire + "; path=/;domain=www.csstop.com"

Delete the cookie
