I tried to save a number in javascript in document.cookie.
But when i try to get a cookie with a number i'm always getting NaN when i try to display it
var playerCoffeeCount = 0;
function setCookie(c_name, value, exdays) { //Setting a cookie (just a shortcut for making cookies)
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 getCookie(c_name) { //Getting a cookie (another shortcut)
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 saveGame(){
setCookie("playerCoffeeCookie", playerCoffeeCount, 999);
}
function loadGame(){
playerCoffeeCount = getCookie("playerCoffeeCookie");
}
function displayCookie(){
document.getElementById("coffeecount").innerHTML= "Coffee: " + Math.floor(playerCoffeeCount);
}
This cookie system in JavaScript saves the value, but it displays as a NaN... Please help :(
try this, working good.
function createCookie(name,days,value) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
function readCookie(name) { //cookie reader function
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;
}
function eraseCookie(name) { //cookie eraser function
createCookie(name,"",-1);
}
createCookie("test", 1, 1);
var mycookie= readCookie("test");
mycookie = parseFloat(mycookie);
console.log(mycookie);
I just found out you just have to disable autosave then hard reset then immediately exit out the tab and if it doesn't work keep trying till it does

So what im tryin to do is to check for a cookie existance (for example accepted=yes) If it is not set, it will return nothing and if not, it will execute some script and set the accepted=yes cookie. So that on the next visit the visitor wont see the popup.
var cookie = document.cookie;
if (cookie = accepted=yes) {
} else {
document.cookie = "accepted=yes";
}
That is the code i have discovered.
You can use getCookie and setCookie Functions
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 "";
}
Example
var user = getCookie("username");
if (user != "") {
alert("Welcome again " + user);
} else {
user = prompt("Please enter your name:", "");
if (user != "" && user != null) {
setCookie("username", user, 365);
}
}
Reference: W3Schools https://www.w3schools.com/js/tryit.asp?filename=tryjs_cookie_username
When a user click on a button it would take them to a link but before they go to that link, the cookie will need to be set to either English (EN) or French (FR). I got an example here:
http://www.quirksmode.org/js/cookies.html
but for some reason, it's not reading in the cookie and I'm not sure where I'm going wrong.
This is what I have:
<!DOCTYPE html>
<html>
<body>
<p>This is for the Browser Cookies.</p>
<button onclick="EN_Cookie()">English Link</button> <button onclick="FR_Cookie()">French Link</button>
<script>
function EN_Cookie() {
setCookie("SMDCookie","EN",7);
//location.href = 'https://google.com';
}
function FR_Cookie() {
setCookie("SMDCookie","FR",7);
//location.href = 'https://google.com';
}
function setCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
</script>
</body>
</html>
Any suggestions??
I reviewed your code and found your set cookie function is correct.
May be your getCookie not working, i am sharing get cookie function:
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) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
Here are functions you can use for creating and retrieving cookies
function createCookie(name, value, days) {
var expires;
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = "; expires=" + date.toGMTString();
}
else {
expires = "";
}
document.cookie = name + "=" + value + expires + "; path=/";
}
function getCookie(c_name) {
if (document.cookie.length > 0) {
c_start = document.cookie.indexOf(c_name + "=");
if (c_start != -1) {
c_start = c_start + c_name.length + 1;
c_end = document.cookie.indexOf(";", c_start);
if (c_end == -1) {
c_end = document.cookie.length;
}
return unescape(document.cookie.substring(c_start, c_end));
}
}
return "";
}
Copied from How do I create and read a value from cookie with javascript?
Below are the two functions I currently use inorder to read and create my cookie (cookie should only be valid for 1 day)
function set1DayValidationCookie(){
var d = new Date();
var today = d.getMonth() + '' + d.getDate();
if (readCookie('onedaycookie') != today) {
document.cookie = 'onedaycookie='+today;
console.log('cookie has been created');
} else {
alert('cookie already exist!');
}
}
function readCookie(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;
}
On refresh of the page, cookie is recognized however
for example, I change my url from www.mywebsite.com/en/ to www.mywebsite.com/ru/
(for language purposes) cookie has been created again.
I would like to ask what I am missing on this part?
You need to set the 'path' part of the cookie to '/'. Then it will Work for all paths.
document.cookie = "username=John Smith; expires=Thu, 18 Dec 2013 12:00:00 UTC; path=/";
Witout the path, the cookie will be set for the current path only.
I would suggest this code
window.cookie = {
set: function(c_name, value, exdays, path = '/') {
var exdate = new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value = escape(value) + ((exdays == null) ? "" : ("; expires=" + exdate.toUTCString())) + "; path=" + path;
document.cookie = c_name + "=" + c_value;
},
get: function(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);
}
}
}
};
And you can check like this:
if("undefined" !== typeof cookie.get('lang')){
//cookie is not set
cookie.set('lang', 'en', 1);
}else{
//cookie is set
}
I created javascript cookie. But i can't read that cookie in wordpress. setcookie() function also not working. Only $_COOKIE is working .But it expiring in one minute.
You can use following javascript function to create, read and delete cookies
CREATE COOKIE
`
function createCookie(name, value, days) {
var expires;
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = "; expires=" + date.toGMTString();
} else {
expires = "";
}
document.cookie = encodeURIComponent(name) + "=" + encodeURIComponent(value) + expires + "; path=/";
}
`
READ COOKIE
`
function readCookie(name) {
var nameEQ = encodeURIComponent(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 decodeURIComponent(c.substring(nameEQ.length, c.length));
}
return null;
}
`
DELETE COOKIE
`
function eraseCookie(name) {
createCookie(name, "", -1);
}
`
Now, call javascript functions as:
createCookie('test','hello','5');
readCookie('test');
eraseCookie('test');
I'm creating an add [ITEM] feature to my site that will include cookies.
Now the Add [ITEM] part works but I need an Remove [ITEM].
This is my code:
$(window).load(function(){
function getCookie(c_name){
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++){
x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
x=x.replace(/^\s+|\s+$/g,"");
if (x==c_name){
return unescape(y);
}}}
function setCookie(c_name,value,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;
}
$(document).ready(function(){
var cookieyess=getCookie("save");
if(cookieyess!==undefined&&cookieyess!==null&&cookieyess!==""){
$('#save1').show();
}
else{
$('#save1').hide();
}
});
$('#save_1').click(function(){
var cookieyes=getCookie("save");
if(cookieyes!==undefined&&cookieyes!==null&&cookieyes!==""){
$('#save1').show();
}
else{
$('#save1').show();
setCookie("save","yes",365);
}
});
});
Now I need to make a function so when you click Removes it deletes that Cookie.
To delete mycookie, this should work by setting an expiration date in the past:
setCookie("mycookie", "", -1)
Here is a small library that I wrote:
var myCookieHandler = (function () {
return {
createCookie: function (name, value, days) {
var expires = "";
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = "; expires=" + date.toGMTString();
}
document.cookie = name + "=" + value + expires + "; path=/";
},
readCookie: function (name) {
var nameEq = name + "=";
var ca = document.cookie.split(';');
var i;
for (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;
},
deleteCookie: function (name) {
this.createCookie(name, null, -1);
}
};
}());
usage:
myCookieHandler .writeCookie("Login","true",2);
var cookieValue=myCookieHandler.readCookie("Login");
myCookieHandler.deleteCookie("Login");
Hope this helps..
