Trying to set a cookie onto self.parent.win dow.opener

[Phil Powell]

I thought this would work but it seems to not work neither in Netscape
nor in IE:

<script type="text/javascript">
<!--
 
// OBTAINED FROM http://www.javascripter.net/faq/settinga.htm
 
// NOTE THAT IF YOU SET days TO -1 THE COOKIE WILL BE SET TO YESTERDAY
AND THUS EXPIRE
function setCookie(name, value, days) {
var today = new Date();
var expire = new Date();
if (days == null || isNaN(days) || days == 0) days = 1;
if (days >= 1 || days < 0) expire.setTime(today.getTime() + 3600000 *
24 * days);
document.cookie = name + '=' + escape(value) + ';expires=' +
expire.toGMTString();
}
 
 
setCookie('val_chat', '**DELETE**', -1);
self.parent.window.opener.document.writeln(document.cookie); //
DELETE PARENT WINDOW'S COOKIE
self.parent.window.opener.location.href = 'chat.jsp';
self.parent.close();
//-->
</script>
<noscript><!-- NO EQUIVALENT --></noscript>
 

However, instead of the expired cookie being set into the frame's
parent's window.opener document, nothing is set, however, redirection
takes place but incorrectly since the cookie's instance still exists
when the window.opener is refreshed.

So how have you guys done this correctly where I have gone wrong?

Thanx

DELETE PARENT WINDOW'S COOKIE

This code write something to parent window document, but not operate
with its cookie.
Try to add extra parameter to the function "setCookie" :
function setCookie(name, value, days, docCookie)
{
.....

Change:

document.cook ie = name + '=' + escape(value) + ';expires='+
expire.toGMTS tring();

To:
docCookie.cooki e = name + '=' + escape(value) + ';expires='
+expire.toGMTSt ring();
......

And then:
setCookie('val_ chat', '**DELETE**', -1,
self.parent.win dow.opener.docu ment);
Maybe it works, but I don't test.

I'm sorry I do not understand this. :(

Add extra parameter docCookie:

function setCookie(name, value, days, docCookie) {

 

  var today = new Date();

  var expire = new Date();

  if (days == null || isNaN(days) || days == 0) days = 1;

  if (days >= 1 || days < 0) expire.setTime(today.getTime() + 3600000 *

 24 * days);

  document.cookie = name + '=' + escape(value) + ';expires=' +

 expire.toGMTString();

 

Set desired value to docCookie:

docCookie = name + '=' + escape(value) + ';expires=' +

expire.toGMTString();

 

 }

     setCookie('val_chat', '**DELETE**', -1);

 

Sorry, I was wrong here, last parameter must be

self.parent.window.opener.document.cookie

(not self.parent.window.opener.document)

 

setCookie('val_chat', '**DELETE**', -1,

self.parent.window.opener.document.cookie);

     self.parent.window.opener.document.writeln(document.cookie); //

 

Function writeln() writes content of document.cookie to

self.parent.window.opener.document but not set its cookie. To set

cookie of self.parent.window.opener.document you should do it directly:

self.parent.window.opener.document.cookie="...". I guess this line of

code is wrong.

 DELETE PARENT WINDOW'S COOKIE

     self.parent.window.opener.location.href = 'chat.jsp';

     self.parent.close();

 

I don't understand what are you going to achieve with this code and

can't comment it.

Sorry for my English
