Cookies aren't available on new window on localhost

I'm using the following code to set a cookie
function setCookie(key, value) {
var expires = new Date();
expires.setTime(expires.getTime() + (1 * 24 * 60 * 60 * 1000));
document.cookie = key + '=' + value + ';expires=' + expires.toUTCString();
}
setCookie('test', '1');
The code is setting the cookie correctly (inspect element reveals the cookie has been set), however only on the page that the cookie is being set. I'm trying to open a new browser window and use that cookie value, however, it won't read the cookie.
I'm also on localhost on my local machine, so I believe that's where the error lies.
How can I fix it so that the cookie I set can be used across all pages on localhost?

this works for me
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
var expires = "expires="+ d.toUTCString();
document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}
setCookie('test', 'Bond007', 365);

Cannot set cookie to expire on browser close

I'm trying to set a cookie using javascript so it expires when the browser is closed.
I have the following function to do that:
function createCookie(value,days) {
var name = "name";
var expires = "";
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days*24*60*60*1000));
expires = "; expires=" + date.toUTCString();
}
var cookie = name + "=" + value + expires + "; path=/";
document.cookie = cookie;
}
I tried many ways found here and there on the web like setting the date to "", setting it to yesterday (in that case the cookie is not even added) and omitting "expires" completly. I tried on Firefox and Chrome checking that every process was stopped before opening again, but the cookie is alway there.
What am I missing?

I am using this function for my self. It will work for you i gess :)
function createCookie(name, value, expiresInX_days, path) {
var a = new Date;
var expires = expiresInX_days || 1;
a.setTime(Date.now() + (1000 * 60 * 60 * 24 * expires));
var pt = path ? " ; path=" + path + ";" : ";";
return (document.cookie = name + "=" + value + ";" + "expires=" + a.toUTCString() + pt) ? !0 : !1;
}

If you want to delete your cookie, you can use this:
function rmCookie(cookieName){
var a = new Date;
a.setTime(0);
return (document.cookie = cookieName + "=;" + a.toUTCString()) ? !0 : !1;
}
If you want get your cookie clean,
function getMyFuckingCookie(cookieName){
var a = document.cookie.replace(/; /g, ";").split(";"),
b = a.length,
c = {},
nm = cookieName || !1;
while (b--) {
var d = a[b].split(/=(.+)/);
c[d[0]] = d[1];
}
return (nm) ? c[nm] : c;
}

Javascript if cookie exist apply css

I want to apply css through javascript if cookie xxxexist - code:
<script>
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
var expires = "expires="+ d.toUTCString();
document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}
var kuki = document.cookie.indexOf('cookie_name=xxx');
alert(kuki);
if (kuki != -1)
{
document.getElementById("ads-back").style.display = "none";
document.getElementById("ffield").style.display = "none";
document.getElementById("bcd").style.display = "none";
}
else { setCookie(xxx, 1, 1) }
</script>
The problem is that I always receiving -1 it should after seting cookie setCookie(xxx, 1, 1) get different value?

setCookie(xxx, 1, 1)
As you are setting cookie name with xxx variable and finding it with cookie_name as below that is the issue..try to find the index of cookie actual name set then it will work.
var kuki = document.cookie.indexOf('cookie_name=xxx');

To save cookie you have to use following format
document.cookie = cname + "=" + cvalue + ";expires=" + expires + ";";
To get saved cookies you have to use following both ways because if you have saved more than one cookie your cookie may not be the first element of the cookie array so you have to check both 'cookie_name=xxx' and
' cookie_name=xxx'
var kuki1 = document.cookie.indexOf('cookie_name=xxx');
var kuki2 = document.cookie.indexOf(' cookie_name=xxx');

Set Expires Time in Cookie Javascript

I have a string that I use to set expires date in cookie. But I always fail to set it. Here is my Code:
var expTime = '2016-06-09T03:06:53Z';
var valueCookie = 'test';
SetCookie('myCookie', valueCookie, expTime);
function SetCookie(name, value, expTime) {
document.cookie = name + '=' + value + '; ' 'expires=' + expTime+ '; path=/';
};
Why I fail to set Expire Date in Cookie?
Thanks

try this
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
var expires = "expires="+ d.toUTCString();
document.cookie = cname + "=" + cvalue + "; " + expires;
}
The parameters of the function above are the name of the cookie (cname), the value of the cookie (cvalue), and the number of days until the cookie should expire (exdays).
The function sets a cookie by adding together the cookiename, the cookie value, and the expires string.

here is my code
function setCookie(name,value,data){
var oDate =new Date();
    oDate.setDate(oDate.getDate()+data);
    document.cookie=name+'='+value+';expires='+oDate;
}

I think there is a syntax error.Try this
var expTime = '2016-06-09T03:06:53Z';
var valueCookie = 'test';
SetCookie('myCookie', valueCookie, expTime);
function SetCookie(name, value, expTime) {
document.cookie = name + '=' + value + '; expires=' + expTime+ '; path=/';
}

Access Cookie created in JS on PHP

I created a cookie via JavaScript, will I be able to access it in PHP too?
JS to create a cookie
function pb_create_cookie(name, value, days2expire, path) {
var date = new Date();
date.setTime(date.getTime() + (days2expire * 24 * 60 * 60 * 1000));
var expires = date.toUTCString();
document.cookie = name + '=' + value + ';' +
'expires=' + expires + ';' +
'path=' + path + ';';
}
pb_create_cookie('tour_in_progress', '1', 30, "/");
pb_create_cookie('tour_id', 105, 30, "/");
pb_create_cookie('tour_step', 0, 30, "/");
Cookie usage in PHP
$tour_id = $_COOKIE['tour_id'];
$tour_progress = $_COOKIE['tour_in_progress'];
$tour_step = $_COOKIE['tour_step'];
