Persistent cookies via Javascript
Hi,
I'm writing an app that requires setting cookies via Javascript.
Problem is that, using Internet Explorer, although I can set and
retrieve them during a browser session, they disappear upon closing
the browser, even when I set an expiry date a significant length of
time into the future (days, years, whatever...).
This doesn't appear to make any difference whether the site is
accessed on localhost or on a remote server.
(Actually, the real problem is that different IE6 windows don't share
cookies- which I need- but this appears to be down to them being
treated as session cookies rather than persistent ones(?))
Here's an example of the code. The setCookie function is a cut-and-
paste example from elsewhere, but it didn't work when I simply set
document.cookie = "whatever=something" either...
<html>
<head>
<script type='text/javascript'>
function setCookie(c_name,value,expiredays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate()+expiredays);
document.cookie=c_name+ "=" +escape(value)+
((expiredays==null) ? "" : ";expires="+exdate.toUTCString());
}
document.write("<br /><br />{" + document.cookie + "}<br />");
setCookie("yellow", "jello", 12);
document.write("<br />{" + document.cookie + "}<br /><br />");
</script>
</head>
</html>
Any help appreciated, thanks.
- MM

IE6 is old, try to install a newer version?

This example works in IE8 (Win7)

That's not a practical solution in this case. Fortunately it wasn't
necessary because...

Yes, both the example listing given on that page (where I got the
setCookie function from originally) works in IE8 *and* IE6. However...
the example I posted above (using w3schools' setCookie) also worked in
IE6 after all. :-O
While it's not clear what the problem was, it's fairly likely that it
was an error on my part (not clearing the cache properly?). Sorry for
wasting your time folks. :-(
