Cookies not being deleted

[Shinori]

Dear forumusers,

 

I'm currently having trouble with deleting my browsercookies. Specifically speaking im trying to delete the cookies of the website the user is currently on.

Here are my JS functions + the proof for existing cookies.

function setCookie(cname, cvalue, days) 
{
	var dt, expires;
	dt = new Date();
	dt.setTime(dt.getTime()+(days*24*60*60*1000));
	expires = "; expires="+dt.toGMTString();
	document.cookie = cname+"="+cvalue+expires+';';
}
function delCookie(name)
{
	document.cookie = name + '= ; expires = Thu, 01 Jan 1970 00:00:00 GMT';
}
function logout()
{
	var cookie = getCookie("member");
	if(typeof cookie != "undefined" || typeof cookie != null || cookie.length > 0)
	{
		delCookie("member");
		window.location.reload();
	}
	else
	{
		alert("Beim Logout ist etwas schief gelaufen!");
		window.location.reload();
	}
}

 

Apparently my browsers language isn't english. Sorry for that. Basically it says that the cookies name is "member", that is has content and expires in 1 day.

 

 

I call the "logout"-function via onclick event in visible DOM. The functions gets called successfully. The cookie existence of "member" is then successfully validated and delcookie() is called. 
The windows gets reloaded as logout() is suppose to do.

Eventually the cookie is NOT being deleted. Any ideas whats going wrong her?

 

Thanks in advance! Sorry for my bad english :S

Does it clear out the value after you try to delete it?

Negative. The cookie is exactly the same after trying to delete it 😕

Try this instead:

document.cookie = name+'=; Max-Age=-99999999;';

Just one question, where's getcookie() function?

Didn't change anything. The cookie still hasn't been deleted.

Here it is: 

function getCookie(cname) 
{
	var name = cname + "=";
	var decodedCookie = decodeURIComponent(document.cookie);
	var ca = decodedCookie.split(';');
	for(var i = 0; i < ca.length; i++) 
	{
		var c = ca[i];
		while (c.charAt(0) == ' ') 
		{
		  c = c.substring(1);
		}
		if (c.indexOf(name) == 0) 
		{
		  return c.substring(name.length, c.length);
		}
	}
  return "";
}

Are you running this locally or with a web server?

[Shinori]

Im running it on a webserver. Plesk to be precise. I tried it cross-browser and it didnt change it either 😕

[justsomeguy]

I don't see any issues, as far as I'm aware that should work fine.

setcookie

expires = ";

Remove semicolon

Should be

expires = "expires="+ d.toUTCString();
