Cookie expires in MS Edge

JavaScript
1

I set Cookie with expiration date:

document.cookie = 'name=value;expires=' + d.toUTCString();

Code above works perfect by Firefox and Chrom, but not by MS Edge. By MS Edge expiration date not available. Could I fix it, or this is persistent Edge bug?

What is d?

3

Object of type Date.

There are many dates that fail when it comes to cookies.

Please supply more details.

This date of one year ahead - april 2020. I don’t think that is the problem.

6

Okay, and with what code are you calculating that one year ahead?

7 
            var d = new Date();
            d.setSeconds(d.getSeconds() + parseInt(_cookieHidden.getAttribute('data-expires')));

            document.cookie = '{name}={value};expires={expires}'
                .replace('{name}', _cookieHidden.getAttribute('data-name'))
                .replace('{value}', value)
                .replace('{expires}', d.toUTCString());

But as I just said, that works fine by all browsers except of Edge.

So now we have 4 more problems to find information about.

  • a mystery _cookieHidden element
  • an unknown data-expires attribute
  • an unknown data-name attribute
  • and an unstated value variable

Can you please supply a simplified example so that we can realistically help you with it?

I suspect .getSeconds doesn’t do what you think it does…

Yes, it doesn’t give the number of seconds since the last epoch. It would be getTime / 1000 that gives that.

Instead, getSeconds just gives a number ranging from 0 to 59.

11

Though of course, that isnt actually the problem here.

A rather important question, though: What domain are you trying to run this on? A TLD? Edge is known to silently drop cookies for TLD’s.

12

I’ve checked d.toUTCString() and that was correct. .getSeconds gives the seconds 0…59, .setSeconds makes automatically correction if given seconds number > 59.

13

No that is not TLD and cookie wasn’t dropped. Just expires doesn’t work.
