This script keeps track of the number of times a surfer has visited page, and show the surfer of this info. Also with buttons to allow him/her to reset info. When the "Revisit Page" button is clicked, it refresh the page. Get the message according to the number of visits and print it. When the "Reset Counter" is clicked, it set the counter to zero and refresh the page. I did coding almost but it's not working. Can anyone tell me what's wrong in my code ?

Try these two functions instead - they work on my eCommerce site.
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=/";
}
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 "";
}
Also make sure your own browser accepts cookies and isn't purging them while you're running tests.

I'm learning to set and get cookies using javascript. Followed the tutorial by w3schools. It works well on the browser but doesn't fetch the cookies on my pc.
<!DOCTYPE html>
<html>
<head>
<script>
function setCookie(cname,cvalue,exdays) {
const d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
let expires = "expires=" + d.toUTCString();
document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}
function getCookie(cname) {
let name = cname + "=";
let decodedCookie = decodeURIComponent(document.cookie);
let ca = decodedCookie.split(';');
for(let i = 0; i < ca.length; i++) {
let c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
function checkCookie() {
let user = getCookie("username");
if (user != "") {
alert("Welcome again " + user);
} else {
user = prompt("Please enter your name:","");
if (user != "" && user != null) {
setCookie("username", user, 30);
}
}
}
</script>
</head>
<body onload="checkCookie()"></body>

I tried repeating the tutorial again but the results were same. I want the cookies displayed on my browser after getting the input
Simply run your .html page on IIS you will get your result
I'm trying to define a version for my website so it can reload the resources if the versions don't match. The problem is that when I fetch the cookie, the cookie value is not returned. The result of this is that the website is in a constant state of reloading.
I made sure that the cookie was there and I tried using my functions in the console and setting the cookie manually.
Webpage:
var version = '1.0.0';
var cVersion = version == getCookie("version");
if(!cVersion) {
setCookie("version", version, 1000);
window.location.reload(true);
}
Cookies 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=/";
}
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 "";
}
The website should reload and update the version number if they are different and do nothing if they are the same.
I'm trying to set cookies that are permanent in Microsoft edge. They last only until I close the browser. Yes I have cookies enabled. Here is some code I found from a while ago:
var cookieHandler = {
setCookie : function(name, value, days, time)
{
var expires = "";
if(days)
{
var date = new Date();
date.setTime(date.getTime() + (time || (days * 24 * 60 * 60 * 1000)));
expires = "; expires=" + date.toUTCString();
}
document.cookie = name + "=" + (value || "") + expires + "; path=/";
},
getCookie : function(name)
{
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i = 0; i < ca.length; i++)
{
var c = ca[i];
while(c.charAt(0) == ' ')
{
c = c.substring(1, c.length);
}
if(c.indexOf(nameEQ) == 0)
{
return c.substring(nameEQ.length, c.length);
}
}
return null;
},
eraseCookie : function(name)
{
document.cookie = name + '=; Max-Age=-99999999999;';
}
};
Yeah when I reopen the browser my cookies are gone. Does anyone have working code for cookies in Microsoft edge?
Edit:
I'm using the file:/// origin.
In this code I am checking if a cookie is set and running a code to pop up a flag selection. If the cookie is not set it will set the cookie once a flaf is checked. It works in chrome but wont work on firefox. I used the code from WC3. Can someone help me find the issue here. Thank you in advance.
<script type="text/javascript">
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=/";
}
function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i = 0; i < ca.length; i++) {
var c = ca[i];

}
function checkCookie() {
var languageSet = getCookie("setLanguage");
if (languageSet != "" || languageSet != null) {
return null;
} else {
jQuery.fancybox("#selectFlagDiv");
setCookie("setLanguage", setLanguage, 365);
}
}
</script>
<div id="selectFlagDiv" onload="checkCookie();" style="display:none;">
<img style="margin-bottom:18px;margin-top:18px;width:300px;height:180px;" src="1.gif" onclick="setLangStorage();" />
<img style="margin-bottom:18px;margin-top:18px;width:300px;height:180px;" src="2.gif" onclick="setLangStorage();" />
</div>
The idea here is to create a sort of "EULA wall". For some reason, whenever I test this code if I don't have the cookie, it works wonderfully, the EULA pops up, the accept button pops up and the accept button gives me the cookie. However, when I have the cookie, nothing in the actual if part happens. I currently have three "commands" one that would bring up the button again (a visual debug of sorts) one that would pass text to a <p></p>, and one that would call a function that runs the open.window(); function:
</script>
<p id = "loc"></p>
<script>
function printButton(){
var btn = document.createElement("BUTTON");
var text = document.createTextNode("accept");
btn.appendChild(text);
btn.setAttribute("onclick", "setCookie('accept','yes',365)")
document.getElementById("loc").appendChild(btn);
}
</script>
<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;
location.reload();
}
</script>
<script>
function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.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) != -1) return c.substring(name.length, c.length);
}
return "";
}
</script>
<p id = "testingstuff"></p>
<script>
function checkCookie() {
var accept = getCookie("accept");
if (accept != "") {
newWindow();
printButton();
document.getElementById("testingstuff").innerHTML = "testing";
} else {
displayEULA();
printButton();
}
}
checkCookie();
</script>
<script>
function newWindow(){
window.open("http://google.com","_self");
}
</script>
</body>
</html>
Seems bizarre that this sort of thing would happen but maybe I'm just missing something obvious.
