Buidling A Cookie
Jun 6, 2007
I have made GreyBox popup automatically when a user visits the site, now I need to set a cookie so it only happens once whenever have a new announcement for our users.
{
document.cookie = "splash_ck=splashpage;expires=Fri, 17 Aug 2007 20:47:11 UTC;path=/";
if (splash_ck = splashpage)
then (GB_showCenter('Watch this to see what we're capable of', 'splash.html', 284, 383);)
else (do nothing)
}
i don't know javascript very well so I am trying to figure out how i should write the if statement.

Can I make a list of hyperlinks that users can customize and save as a cookie by clicking a button and automatically retrieve the cookie so it remembers their list next time? This is kind of what I want to do:

I am making a sort of text based game (Just a hobby) I like to do that sort of thing. So, anyway, considering all I can really do is code HTML, and very, very light javascript, I kinda need some help.
I basicly know how to do everything except affect & Use the cookies. So what I need to do with them is to
#1.) Have a code to change the cookie number, say... on the click of a button.
#2.) Have a code where it only displays certain text if the cookie is a certain number.
I cant code JS and have no idea how hard/easy this is.
If it is insanely hard & needs a master coder, just tell me and ill take it off. I dont want to be wasting anyones time.

I have an embedded system with a web interface. One of the web pages
has a small JavaScript program that, when run on IE6, always displays
the message that cookies need to be enabled:
if (document.cookie.indexOf('asm_session') == -1)
{
document.cookie = 'asm_session=0'
if (document.cookie.indexOf('asm_session') == -1)
{
document.write("Advanced System Management access requires
cookies to be enabled."+'<br><br>');
}
}
This problem only occurs with IE6, not Mozilla. It also only happens
on some of the embedded systems, but this problem exists for everyone
running IE6.
The problem isn't limited to the Javascript code, either. On another
web page from this embedded system, a cookie is set the normal way,
via the HTTP header. This cookie is also rejected.
When I display any page that attempts to set a cookie, IE6 displays
the blocked icon and says that cookies on that URL are blocked.
However, I have set all privacy and cookie options to their most
permissive. I've spent the past hour changing every option I can find
that's even remotely related to cookies and privacy, and nothing
changes. Does anyone have any idea what's going on?

In my web application we are able to store large data in the browser
cookie keeping in mind the limit of 300 cookies per cookie file, 20
keys per cookie per domain and 4KB max size of each cookie. We are
unable to retreive this large amount of data immediately after storing
through document.cookie in IE browser (The same works fine in
Netscape).
Is there any limit on the size of the data that can be retreived using
document.cookie in IE browser? Could you please suggest a solution to
this problem I am facing.

I have this piece of javascript:
document.cookie="fadedin=yes; expires=Fri, 27 Jul 2020 02:47:11 UTC; path=/"
which sets a cookie which prevents an annoying popup from being presented to users of my site after their first visit. It doesn't appear to work in IE6 though,

Very irritating and difficult problem with cookies and IE (5 & 6), maybe someone could give a hint what's wrong. We have a frameset (navigation + banner + footer + main frame, basic stuff), and cookies are set on the main frame's <body OnUnload> event. When i click a link on the navigation the page on the main frame gets unloaded and cookie is set, and then i want to do stuff with that cookie on the next page.
Very simple, but problem is this: if I use IE i have to click the navigation link 2 times (= to load the new page twice) to make it work. And sometimes the values are not shown on the new page even though the cookie is always set properly. I have an alert box on the JS function which is driven correctly on onload and the values seem correct. Basically with IE this cookie stuff works without any sense and logic. Code:

Is there any way to protect the browser's cookie, prevent users from
modifying it?
Seems some browsers, such as Opera, provides a very easy to use
interface for user to modify the cookie value.

I have a problem with cookies set via javascript. What I try to
achieve is, when a user comes on the intranet, he can click on a link (
a simple href) that will set the content to french or english. I want
to set a cookie to persist that choice each time the user comes back on
the intranet. This feature must be available everywhere on the
intranet and the link is placed in an inner asp script called Menu.asp
which is included each time a page loads.
Now, I know it's maybe not the best way to achieve this but I'm just
working from what has been made by others, I cannot change the way
things are made, too much work would be involved and they won't accept
to give time to do everything all over again.
The best approach I got was to set a querystring value and replace the
cookie value from vbscript code. The problem is, the intranet we have
use a lot of the querystrings for a lot of features and when I click
the English/French link, that info is lost. I've tried to set a
mechanism to keep all the querystring and only add a new value but I
got weird results...
So I've turned to Javascript and still got no luck... For some
reasons, the cookie gets deleted from the cookie file as soon as my
javascript modifies the cookie.
Here's an example:

I have been experiencing a lot of troubles in reading a PHP COOKIE from
javascript.
if i write the cookie and read it in javascript in the same PHP file it
works well, but if i write the cookie for instance in a Javascript(AJAX)
called PHP file, the Javascript can read it.

I have a snippet of JS that i want to change so that the cookie it
creates lasts only 48 hours. (or any other length of time i decide, but
48hours seems right for now)
Only thing i can't figure out how it specifies the expiry time.
-----
function makeCookie(Name,Value,Expiry,Path,Domain,Secure){
if (Expiry != null) {
var datenow = new Date();
datenow.setTime(datenow.getTime() + Math.round(86400000*Expiry));
Expiry = datenow.toGMTString();
}
Expiry = (Expiry != null) ? ' expires='+Expiry : ''
Path = (Path != null)?' path='+Path:''
Domain = (Domain != null) ? ' domain='+Domain : ''
Secure = (Secure != null) ? ' secure' : ''
document.cookie = Name + '=' + escape(Value) + Expiry + Path + Domain
+ Secure;
}
function readCookie(Name) {
var cookies = document.cookie;
if (cookies.indexOf(Name + '=') == -1) return null;
var start = cookies.indexOf(Name + '=') + (Name.length + 1);
var finish = cookies.substring(start,cookies.length);
finish = (finish.indexOf('') == -1) ? cookies.length : start +
finish.indexOf('');
return unescape(cookies.substring(start,finish));
}
function setActiveStyleSheet(pTitle) {
var vLoop, vLink;
for(vLoop=0; (vLink = document.getElementsByTagName("link")[vLoop]);
vLoop++) {
if(vLink.getAttribute("rel").indexOf("style") != -1 &&
vLink.getAttribute("title")) {
vLink.disabled = true;
if(vLink.getAttribute("title") == pTitle) vLink.disabled = false;
}
}
}
function selectStyle (vCookieName, vSelection) {
//WRITE COOKIE
makeCookie(vCookieName, vSelection, 90, '/');
//ACTIVE SELECTED ALTERNAT STYLE SHEET
setActiveStyleSheet(vSelection)
}
if (document.cookie.indexOf('style')!=-1) {
css = readCookie('style');
//ACTIVATE SELECTED STYLE SHEET
setActiveStyleSheet(css)
}

This code writes a cookie to save the li's position after a user has sorted them to their preference. It's only designed to handle One unordered list. I'm trying to have it handle 3 unordered lists under the same page. It needs to write 3 cookies, and then read them when the user returns.
Code:
/// set the list selector
var setSelector = ".list1";
// set the cookie name
var setCookieName = "listOrder";
[Code]...

I have a some code that I have been working on but I do not have the greatest understanding of cookies. Basically I have a cookie called webvpn and I need the data from the content part of the cookie. Then I need to use that at the beginning of my url. The content looks something like this, 791152394@265814016@1305568856@B762F295B8829D242481C9DD285D0339A719D96C
So I need to get the data from content and then use that in the code where it says VARFROMCOOOKIEHERE then basically the rest of the link goes after it.
Here is what I have so far:
<html>
<body>
<script language="javascript" type="text/javascript">
if (navigator.appVersion.indexOf("Mac")!=-1){

Alright, I have a problem killing a cookie. I'm able to succesfully create a cookie with php (or rather several cookies). If it matters, heres the code:
setcookie("loggedin", "true", $inTwoMonths, "/testzone/", "excalo.com");
setcookie("username", $unames[$i], $inTwoMonths, "/testzone/", "excalo.com");
setcookie("password", $passes[$i], $inTwoMonths, "/testzone/", "excalo.com");
The files are in a folder called testzone in excalo.com.
I need to delete them (that is, the cookies) with javascript. Interestingly, when I run the same files without the "/testzone/" in my main directory, everything is fine and dandy. When I run them in the testzone folder, it doesn't work. FF/Firebug aren't giving me errors. Neither is PHP. Here's the javascript: Code:

I'm trying to read a cookie that I've set with php with javascript. The cookie is for storing the username when logging in to a site. If the cookie has been set I want the focus in the inline popup to target the password field so that the user doesn't have to tab down from the username field of the login form.
The php script stores the cookie perfectly:
if (isset($_POST['remember'])){
$expire = time()+60*60*24*30;
setcookie("login_username", $username, $expire);
echo $_COOKIE['login_username'];
} else {
if (isset($_COOKIE['login_username']) || isset($_COOKIE['password'])){
$expire = time()-3600;
setcookie("login_username", "", $expire);
}}
The javascript:
if (targetfocus == 'login_username'){
alert(readCookie('login_username'));
if (readCookie('login_username') == 'username'){
targetfocus = 'password';
}}
$("#"+targetfocus).focus();
...
function readCookie(name) {
var cookieName = name + "=";
var cookieArray = document.cookie.split(';');
for (var i = 0; i < cookieArray.length; i++){
var cookie = cookieArray[i];
while (cookie.charAt(0)==' '){
cookie = cookie.substring(1,cookie.length);
}if (cookie.indexOf(cookieName) == 0){
return cookie.substring(cookieName.length,cookie.length);
}return null;
}}
But when trying to read the cookie in the javascript code I receive null when I put an alert to the code. Why won't the javascript find the cookie? Is it because I'm running the site localhost on my laptop? Does that have an effect on cookies?

I currently have a site which uses cookies, the problem is that I want it to detect if the browser being used has cookies enabled. I know you can accomplish this by setting a cookie in JavaScript and testing for it (i don't know how to do it, though), *BUT* I need the script to be compliant with all (or at least most) browsers. By this I mean, Mozilla, Firebird, Opera, IE, Netscape, and anything else you can think of.

Basically I have a form where the user enters their info (name, last name, email) then clicks the add button to store their info into an array that I made. Then, the user can enter say... "Bill" in the first name field, click the search button, and in the text box, all results with bill will show up.
What I need to do is instead of the information being stored in the array when the user clicks add, is to store it as a cookie with a comma separated string like this: "lastname,firstname,emailid"
Then when the users clicks the search button, the info is retrieved from a cookie, not the array.
