I have some trouble with a warning box on my site. It uses a cookie to hide it when people click on a link. However the box keeps returning when I restart the browser.

simple java funtion:

function setCookie()

{

document.cookie = 'hidewarning=true; expires:Sun, 31-May-2099 23:59:59 GMT;';

}

Can someone tell me what I did wrong?

: should be =.

function setCookie() 
{ 
 var expDate = new Date();
   
 expDate.setDate( expDate.getDate() + 30 );

 document.cookie = 'hidewarning=true;expires=" + expDate.toGMTString() + ";path=/";
}

Still doesn't do what it's supposed to do. Here's the code on my php page with the warning box

In the head section:

<?php
function ae_detect_ie()
{
if (isset($_SERVER['HTTP_USER_AGENT']) &&
(strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false))
return true;
else
return false;
}
?>
<?php if (ae_detect_ie()) {
if (isset($_COOKIE['hidewarning'])) {}
else { ?>
<script type="text/javascript">
function setCookie()
{
var expDate = new Date();

expDate.setDate( expDate.getDate() + 30 );

document.cookie = 'hidewarning=true;expires=" + expDate.toGMTString() + ";path=/';
}
</script>
<?php }} ?>

The body part:

<?php
if (ae_detect_ie()) {
if (isset($_COOKIE['hidewarning'])) {
echo "<!-- IE warning hidden -->\n";
}
else { ?>
<div id="warningbox" align="center">
<table width="960" class="bottom">
<tr>
<td rowspan="2" valign="top">
<img src="/images/warning.png" align="left" alt="" />
</td>
<td class="bottom" align="left">
Beste Internet Explorer gebruiker! De kans bestaat dat U niet goed beveiligd bent en/of U deze site niet goed kunt bekijken door het gebruik van Internet Explorer. Schakel vandaag nog over naar een <u>alternative</u> browser. <a href="/browser.php" class="botlink">Klik hier</a> voor meer informatie voor het <u>alternatief</u> dat wellicht beter voor U zult werken.
</td>
</tr>
<tr>
<td align="right" class="bottom">
<a href="javascript:setCookie()" onclick="document.getElementById('warningbox').sty le.display='none'" class="botlink">klik hier</a> om dit bericht niet meer te tonen.
</td>
</tr>
</table>
</div>
<?php }} ?>

The box is only hidden when the user does not close his/her browser

<a href="javascript:setCookie()" onclick="document.getElementById('warningbox').sty le.display='none'" class="botlink">klik hier</a> om dit bericht niet meer te tonen.

Is there a space in the property like that in your actual code?

No that happend after the copy & paste

The hiding of the box (div's) aint the problem. That works wonderfully. It simply keeps re apearing everytime I restart internet explorer.

As long as you're using PHP, why don't you use the setcookie function instead?
setcookie

As far as I know it would reload the page to call that function. I also like to use this script on multiple locations of the site. Meaning it won't just be a warningbox at the top of a page.

It works with a single session in internet explorer. Can internet explorer be the problem?

setcookie() does not reload the page. Use it before any HTML is outputted. I personally never set cookies with JavaScript. Cookies weren't even originally intended to be used with JS, and I'm not even sure if there are differences with IE when setting it with JS or not.

I've read that IE sometimes forces cookies to expire when the browser closes if it feels your sites privacy policy isn't inline with the user privacy settings. It may be possible that your browser security settings are causing this.

I've added a privacy policy to my site (and man was it a world of pain doing so)

Yet no luck!

I validated it and it seems okay:

Changed the cookie function to:

<script type="text/javascript">
function setCookie()
{
exp=new Date();
plusMonth=exp.getTime()+(31*24*60*60*1000);
exp.setTime(plusMonth);
document.cookie='hidewarning=true;expires='+exp.to GMTString();
}
</script>
