How Can I Set The Cookie Expire Every 30 Seconds [duplicate]

Could someone update the following code to make the cookie expire in 30 seconds.
function setCookie(c_name, value, exdays) {
var exdate = new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
document.cookie = c_name + "=" + c_value;
}

function createCookie(name, value) {
var date = new Date();
date.setTime(date.getTime()+(30*1000));
var expires = "; expires="+date.toGMTString();
document.cookie = name+"="+value+expires+"; path=/";
}

You can specify the maximum age in seconds when setting a cookie:
function setCookie(name, value, maxAgeSeconds) {
var maxAgeSegment = "; max-age=" + maxAgeSeconds;
document.cookie = encodeURI(name) + "=" + encodeURI(value) + maxAgeSegment;
}
Usage:
setCookie("username", "blaise", 30);

6 month expiration date on a javascript cookie

I'm not great with javascript, but I have one that is working, but it seems like it's not following the 6 month expiration date that I set. Can someone help troubleshoot? This is what I have when setting the cookie's expiration date:
expDate = new Date;
// in the following line, 180 means 180 days.
expDate.setTime(expDate.getTime() + 180 * 24 * 60 * 60 * 1000);
expDate.toGMTString();
function setCookie(name, value, expires, path, domain, secure){
document.cookie= name + "=" + escape(value) +
((expires) ? "; expires=" + expires.toGMTString() : "") +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
((secure) ? "; secure" : "");
}
function getCookie(name){........
Any help troubleshooting would be perfect and very appreciated!
UPDATE - here is the script in its entirety. I'm calling a pop-up window only to show if it's been 3 page visits, and 20%, and 6 months expiration date. Just piecing it together so take it easy on me!!
expDate = new Date;
// in the following line, 180 means 180 days.
expDate.setTime(expDate.getTime() + 180 * 24 * 60 * 60 * 1000);
expDate.toGMTString();
function setCookie(name, value, expires, path, domain, secure){
document.cookie= name + "=" + escape(value) +
((expires) ? "; expires=" + expires.toGMTString() : "") +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
((secure) ? "; secure" : "");
}
function getCookie(name){
var dc = document.cookie;
var prefix = name + "=";
var begin = dc.indexOf("; " + prefix);
if (begin == -1){
begin = dc.indexOf(prefix);
if (begin != 0) return null;}
else{begin += 2;}
var end = document.cookie.indexOf(";", begin);
if (end == -1){end = dc.length;}
return unescape(dc.substring(begin + prefix.length, end));
}
visits = getCookie('nVisits');
if (!visits) {
visits = 1
};
if (visits == 3)
if ((Math.random() * (100 - 1) + 1) < 20)
{
window.open("https://mypoup.html", "_blank", "toolbar=yes,scrollbars=yes,resizable=yes,top=500,left=500,width=400,height=400");
}
if (visits < 3) {
++visits;
cookieData = visits;
setCookie('nVisits', cookieData, expDate)
}

Kaddath's comment solved the problem:
it seems that toGMTString() is obsolete and should not be used anymore, use toUTCString() instead.

Javascript cookie path not working as expected on iOS. Appears to be set per page

I'm trying to set a cookie with javascript which is valid for a whole domain. This works everywhere except on iOS where the cookie becomes valid only for the page it was set on. For example cookie set via mydomain.com/cat/123 is not found when trying to fetch it on mydomain.com/cat/338
var d = new Date();
d.setTime(d.getTime() + (7*24*60*60*1000));
expires = d.toUTCString();
document.cookie = 'abc_rem=true;' + ' expires=' + expires +'; domain=mydomain.se; path=/';
The problem appears in both Safari and Chrome on iOS. I have tried searching for answers to no avail. What am I doing wrong?
Thanks in advance!

The following works for me:
function setCookie() {
var c_name = "abc_rem";
var value = "true", exdays = 365;
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
var c=c_name + "=" + c_value + ";path=/";
document.cookie=c;
}
And this is how I get the cookie afterwards
function getCookie(c_name) {
var i,x,y,ARRcookies=document.cookie.split(";");
var found = false;
for (i=0;i<ARRcookies.length;i++) {
x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
x=x.replace(/^\s+|\s+$/g,"");
if (x==c_name) {
found = true;
}
}
if (found) {
// do whatever you need to do here
}
}

javascript Cookie for every 24 hours in window open code not working

I have a simple popup code , it opens two sites with one click.
Now the problem is that it doesn't work for every 24 Hours. It works many many times a day.
Where is wrong in my own code? How can i solve this ?
function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
{
x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
x=x.replace(/^\s+|\s+$/g,"");
if (x==c_name)
{
return unescape(y);
}
}
}
function setCookie(c_name,value){
var exdays= 1;
var exdate=new Date();
exdate.setHours(exdate.getHours() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie=c_name + "=" + c_value;
}
function checkCookie(){
var username1=getCookie("tabligh1");
var usernam = "sendshod";
if(username1==null){
window.open('#','_parent','toolbar=1,location=1,directories=1,status=1,menubar=1,scrollbars=1,resizable=1');
window.focus();
}
if(username1=="" | username1==null){
if(window.open('site adress1','_blank','toolbar=1,scrollbars=1,location=1,statusbar=1,menubar=1,resizable=1')){
window.focus();
setCookie("tabligh1",usernam);
}
}
if(username1=="" | username1==null){
if(window.open('site adress2','_blank','toolbar=1,scrollbars=1,location=1,statusbar=1,menubar=1,resizable=1')){
window.focus();
setCookie("tabligh1",usernam);
}
}
}
document.onclick = checkCookie;
if ((window.XMLHttpRequest == undefined) && (ActiveXObject != undefined)) window.onload = checkCookie;

Your setCookie() function is setting the cookie to expire 1 hour from now, not 24 hours from now.
As you can see here in your code:
function setCookie(c_name, value) {
var exdays = 1;
var exdate = new Date();
exdate.setHours(exdate.getHours() + exdays);
var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
document.cookie = c_name + "=" + c_value;
}
You are setting the expiration time to one hour from the current time. Perhaps you meant to increment the time by one day, not one hour?

javascript getting setting deleteing cookies

I am having trouble setting and deleting cookies in php Ive got no problem.. in javascript eh.. lots I know this question is everywhere but all the answers I come across seem to bring me the same fate so I have no idea whats going on.. this is what I have currently.
SetCookie("username",ztsUser,14,'/', '');
function SetCookie (name,value,expires,path,domain,secure) {
document.cookie = name + "=" + escape (value) +
((expires) ? "; expires=" + expires.toGMTString() : "") +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
((secure) ? "; secure" : "");
}
the error:
expires.toGMTString is not a function
The whole lot of cookie functions I have.. is:
var today = new Date();
var expiry = new Date(today.getTime() + 365 * 24 * 60 * 60 * 1000);
function getCookieVal (offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1) { endstr = document.cookie.length; }
return unescape(document.cookie.substring(offset, endstr));
}
function GetCookie (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg) {
return getCookieVal (j);
}
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function DeleteCookie (name,path,domain) {
if (GetCookie(name)) {
document.cookie = name + "=" +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
"; expires=Thu, 01-Jan-70 00:00:01 GMT";
}
}
function SetCookie (name,value,expires,path,domain,secure) {
document.cookie = name + "=" + escape (value) +
((expires) ? "; expires=" + expires.toGMTString() : "") +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
((secure) ? "; secure" : "");
}
if anyone knows a better method Im all ears.. but this is what I got at the moment, I need to set, update, delete, get the value of.. cookies

toGMTString has been deprecated. Try toUTCString instead:
function SetCookie (name,value,expires,path,domain,secure) {
document.cookie = name + "=" + escape (value) +
((expires) ? "; expires=" + expires.toUTCString() : "") +
((path) ? "; path=" + path : "") +
((domain) ? "; domain=" + domain : "") +
((secure) ? "; secure" : "");
}
You're also passing a number (14) when the function expects a Date (expires.toUTCString):
SetCookie("username", ztsUser, 14, '/', '');
What is 14 intended to be? 14 days? Assuming that, you can add this at the top of the function to support both numbers and dates:
if ('number' === typeof expires) {
expires = new Date(new Date().getTime() + expires * 86400000);
}
86400000 is the number of milliseconds in a day -- 24 * 60 * 60 * 1000.

There are already a number of great libraries for handling cookies in JS. Why not use one of them? Just go to your favorite search engine and enter "javascript cookie library" to find one.
