Question

I am able to get the current date, but I don’t know how to get the current date + 1 day (in GMT)

var now = new Date();
var newexp = (now + 3);
var show = newexp.getGMTString();

alert(show);

What I’m really trying to do is set a cookie to expire in 1 day.

function SetCookie(name, value, exp) {
 var now = new Date();
 var newexp = (now + exp); // exp being # of days before expiration
 document.cookie= name + "=" + value+ "; expires=" + newexp.getGMTString() + ";"
}

SetCookie('name', 'john', '3');

Obviously, this is not working.

Answer 1

function SetCookie(name, value, exp) {
var now = new Date();
now.setTime(now.getTime()+(exp*24*60*60*1000));
document.cookie= name + "=" + value+ "; expires=" + now.toGMTString() + ";"
}

SetCookie('name', 'john', '3');

edited it to take the exp as the factor, it is the no. of days.
