A cookie must be set and also confirmed.
However, I want to change the text of the confirmation box? Is there any way?
Like OK=Hello and Cancel=Reset in the example below:
HTML:
<body onload="checkCookie()"></body>
Javascript:
function getCookie(c_name)
{
var c_value = document.cookie;
var c_start = c_value.indexOf(" " + c_name + "=");
if (c_start == -1)
{
c_start = c_value.indexOf(c_name + "=");
}
if (c_start == -1)
{
c_value = null;
}
else
{
c_start = c_value.indexOf("=", c_start) + 1;
var c_end = c_value.indexOf(";", c_start);
if (c_end == -1)
{
c_end = c_value.length;
}
c_value = unescape(c_value.substring(c_start,c_end));
}
return c_value;
}
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 checkCookie()
{
var username=getCookie("username");
if (username!=null && username!="")
{
var conf = confirm("Welcome again " + username);
if(conf==true)
{
return false;
}
else
{
alert("Your cookies have been reset!");
}
}
else
{
username=prompt("Please input your name below:","");
if (username!=null && username!="")
{
setCookie("username",username,365);
}
}
}
In addition, is there any way to be done like this:
When the entered username is set, being also reset while Cancel/Reset is clicked.
I wouldn't complain if somebody uses jQuery to do so though.
Thanks in advance. I will rep who helps me out :)

There are other options using some jQuery plugin, you can edit OK & Cancel button text. Helpful links:
http://www.codeproject.com/Questions/431829/How-to-change-button-text-of-Alert-message-using-j
Display Yes and No buttons instead of OK and Cancel in Confirm box?

Logically this seems to be correct. However, either the setCookie or getCookie functions simply aren't firing?
cookie.js
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 getCookie(c_name)
{
var c_value = document.cookie;
var c_start = c_value.indexOf(" " + c_name + "=");
if (c_start == -1)
{
c_start = c_value.indexOf(c_name + "=");
}
if (c_start == -1)
{
c_value = null;
}
else
{
c_start = c_value.indexOf("=", c_start) + 1;
var c_end = c_value.indexOf(";", c_start);
if (c_end == -1)
{
c_end = c_value.length;
}
c_value = unescape(c_value.substring(c_start,c_end));
}
return c_value;
}
index.php
var newCookie = parseInt(getCookie("liked_count"));
if(newCookie != null && newCookie != ""){
newCookie += 1;
setCookie("liked_count",newCookie,5);
}else{
setCookie("liked_count",1,5);
}
No matter which side of the if statement it follows, no cookie is set regardless. From what I can tell there are no errors or warnings, so could it be that it cannot find the setCookie and getCookie function inside the my cookies.js file?
The cookies.js file successfully locates, so I'm at my wits end here.
<head>
<script type="text/javascript" src="assets/js/cookies.js"></script>
</head>
Any help would be much appreciated!
EDIT:
Oh sorry, this is embarrassing... It turns out that the cookie.js file was being cached and I had actually moved file location. It was that simple. Sorry for this waste of time!
The problem you're having is with your use of:
var newCookie = parseInt(getCookie("liked_count"));
MDN parseInt Documentation
parseInt returns NaN if it fails. Instead of the following line:
if(newCookie != null && newCookie != ""){
you should have
if(!isNaN(newCookie)) {

<a onClick="document.getElementById('ac-wrapper').style.display='none'; setCookie('abc', 'def', 365)" href="#" style="text-decoration: none;">OK</a>

to
setCookie('abc', 'def', 1)
I am trying to write a code that will display a pop-up message when a site is first visited and I want it to never display again if I already see it.. Here's my code, I hope someone could help me to prevent the pop up from appearing when I refresh the page although it shouldn't.
<SCRIPT LANGUAGE="JavaScript">
<!--
function GetCookie(cookie) {
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 "here";
i=document.cookie.indexOf(" ",i)+1;
if (i==0) break;
}
return null;
}
var visit=GetCookie("cookie");
if (visit==null){
alert("Your Message Goes here and you only get to see it once!");
var expire=new Date();
expire=new Date(expire.getTime()+7776000000);
document.cookie="cookie=here; expires="+expire;
}
// -->
</SCRIPT>
You have problems in your getCookie function. Try with this:
CODE
function getCookie(c_name) {
var c_value = document.cookie;
var c_start = c_value.indexOf(" " + c_name + "=");
if (c_start == -1) {
c_start = c_value.indexOf(c_name + "=");
}
if (c_start == -1) {
c_value = null;
} else {
c_start = c_value.indexOf("=", c_start) + 1;
var c_end = c_value.indexOf(";", c_start);
if (c_end == -1) {
c_end = c_value.length;
}
c_value = unescape(c_value.substring(c_start, c_end));
}
return c_value;
}

I am trying to create a webpage that has an alert when you start it. User will get prompted to enter name or your username. The username will get saved in a cookie. Everytime a new session gets started user will see a message saying "hello" + username. However, I haven't been able to do it without getting the message to popup after visiting a new part of the webpage.
This is my code so far:
HTML
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 getCookie(c_name)
{
var c_value = document.cookie;
var c_start = c_value.indexOf(" " + c_name + "=");
if (c_start == -1)
{
c_start = c_value.indexOf(c_name + "=");
}
if (c_start == -1)
{
c_value = null;
}
else
{
c_start = c_value.indexOf("=", c_start) + 1;
var c_end = c_value.indexOf(";", c_start);
if (c_end == -1)
{
c_end = c_value.length;
}
c_value = unescape(c_value.substring(c_start,c_end));
}
window.c_value = c_value
return c_value;
}
function alertornot(){
if (get_cookie('alerted')==''){
loadalert()
document.cookie="alerted=yes"
}
}
function loadalert(){
alert(window.username + "we meet again" )
}
function alert() {
var username=getCookie("username");
if (username!=null && username!="") {
if (once_per_session==0) {
loadalert()
}
else {
alertornot()
}
}
else {
username=prompt("Please enter your name:","");
// window.username = username
if (username!=null && username!="") {
setCookies("username", username, 365)
}
}
}
I'm very new to programming and javascript. I am so sorry, if this is a stupid question.
You write "setCookies(...)", but it's "setCookie" without "s".
You make infinite loop, because you replace "alert(...)" native function and call alert() in this function.
Execute schema : alert() > loadalert() > alert() > loadalert() > etc...
Rename your function.
You didn't define "once_per_session" variable.
Javascript
function n_alert() {
window.username = getCookie("username");
console.log(username);
if (username!="undefined" && username!==null && username!=="") {
alert(window.username + " we meet again" );
} else {
username=prompt("Please enter your name:","");
if (username!==null && username!=="") {
setCookie("username", username, 365);
}
}
}
n_alert();

You should not name a function alert as it is a global object already. Also, I do not see where you are calling any of this code.
I would rename the alert function to promptUser (or something) and add this code to the bottom:
promptUser();
loadAlert();
Try this:
<script>
function getCookie(c_name)
{
var c_value = document.cookie;
var c_start = c_value.indexOf(" " + c_name + "=");
if (c_start == -1)
{
c_start = c_value.indexOf(c_name + "=");
}
if (c_start == -1)
{
c_value = null;
}
else
{
c_start = c_value.indexOf("=", c_start) + 1;
var c_end = c_value.indexOf(";", c_start);
if (c_end == -1)
{
c_end = c_value.length;
}
c_value = unescape(c_value.substring(c_start,c_end));
}
return c_value;
}
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 checkCookie()
{
var username=getCookie("username");
if (username!=null && username!="")
{
alert("Welcome again " + username);
}
else
{
username=prompt("Please enter your name:","");
if (username!=null && username!="")
{
setCookie("username",username,365);
}
}
}
</script>
</head>
<body onload="checkCookie()">
My last anwser here.
The popup still comes when I refresh the page
If you want pop-up only one time (not each refresh page), set one other cookie.
See Make a cookie expire in 30 seconds for set Cookie with second and not with day (for popupcookie).
Javascript
function isCookie(c_name) {
var cook = getCookie(c_name);
return (cook!="undefined" && cook!==null && cook!=="");
}
function n_alert() {
var username = getCookie("username");
if (isCookie("username")) {
if (!isCookie("popupcookie")) {
alert(username + " we meet again" );
} else {
console.log("hidden alert : " + username + " we meet again" );
}
setCookie("popupcookie", username, 1); //restart
} else {
username=prompt("Please enter your name:","");
if (username!==null && username!=="") {
setCookie("username", username, 365);
}
}
}
n_alert();

Remark I found issue, if you use different directory (path) ex : './' and './dir1/1/'. You may have a problem. Like you don't define or re-define root cookie in directory. Maybe use sessionstorage.
can anyone tell me about automatic cookies in JavaScript while clicking a button or URL of a webpage?
It sets for me and I can't delete that also...
var expDate = new Date();
expDate.setYear( parseInt(expDate.getYear())+10);
document.cookie="";
var x = "$user=$val; expires="+expDate.toUTCString();
Here i have two buttons called 'view' and 'save'. If i click the 'save' button this cookie should be set... but when i click the 'view' button a cookie is set. i cant delete tht cookie too
I find the method explained in this article at quirksmode.org to be working just fine. — Mabye give that a try?
