Hey guys,
This error occurs ONLY in Netscape 7.0. Not in 7.1. So, I think it's a
bug. Buuuut...
Has anyone had this problem or know of a fix?
When attempting to have an onunload function set with "window.onload= ",
the error comes up
"permission denied to set property window.onunload "
I can't find a thing on this one. Setting it with the normal "<body
onunload" works fine. But isn't a great thing for me to do, since the
onload is part of a very large menu script.
Here's a test page to illustrate the problem. Netscape 7.0 has a problem
with this. 7.1 does not. IE is fine, too.
<html>
<head>
<title> New Document </title>
<script>
window.onunload ="alert('bye bye');"
</script>
</head>
<body>
test
</body>
</html>

Don't assign a string as an event handler.
window.onunload = function() {
alert('bye, bye');
}
works, as would:
function myOnunload() {
alert('bye, bye');
}
window.onunload = myOnunload;

The original didn't.
This was just for testing.
You don't want to see the whole thing. :)
Here's the one line from the original source, in case it makes sense by
itself.
ScLdAgainWin.on unload=UnLoaded ;
(UnLoaded is a defined function - again, this code works fine in all
other target browsers, including IE5+, NN6.2, and NN7.1)
If you want the whole source, it's HVMenu from dynamicdrive.co m. I've
been using it for some time, but it was only tested up to NN6.2. I
checked for updates, but there were none. I may decide to contact the
author, but if this is a browser bug, I don't want to bother.

Is this assigning a reference to a function defined in the current

No, the code is running from a frameset. It is addressing the main
frame. That doesn't matter, though, since it doesn't work in a regular
page, either.
It doesn't work no matter where you put it, which was what I was showing
in the little test page I posted. It won't let you assign anything to
onunload with script, it has to be in the body tag. Again, this works in
every browser I need it to work in except NN7.0. NN7.1 it works fine.
NN7.0 throws a security exception.

As Grant said, your original test page wasn't going to work because it
was assigning a string instead of a function. But testing:-
<html>
<head>
<title></title>
<script>
function UnLoaded(){aler t('bye bye');}
window.onunload =UnLoaded;
</script>
</head>
<body>
test
</body>
</html>
- worked with (Windows) Netscape 7.00 & 7.02 both from the local file
system and over an HTTP server.
If all else fails, have you considered branching on
window.addEvent Listener and using that for onunload if available?

Not on ours.
I have 2 users who test for me, and they have 7.0, and this gave the
same error.
I wonder if it's something in their settings...
Neither has a user.js file that I could find. I know people can turn off
onunload with a setting in that file, but neither of them have that.

window.addEvent Listener and using that for onunload if available?
I already did a workaround, but it was icky. I put the function call in
the onunload event of each body tag of every damn page (thank goodness
for dreamweaver templates!).
addeventlistene r for onunload did the same error for their browsers.
This wouldn't be that big of a deal if we didn't have a ton of Netscape
users. *sigh*

Morning All,
I have some code for a website which uses 'window.open' to simulate
modal dialog boxes. I use the window.closed property to decide if the
window object exists at various points. This has been fine until last
week when I started getting javascript 'Permission Denied' errors when
I try to access this property.
I suspect that a windows update has caused this somehow, as this code
has not changed for a very long time. Can...
