trouble updating new window frame

[ced]

Hallo,

I have some JS which creates a new 2-frame window.
The new window (via onLoad) backfills a variable
in the parent window so I'll know when it's safe
to load the target frame.

The problem is that no matter what kind of delay
I set (1 or more seconds), trying to update the
new frame always generates a 'newwin no properties'
type error.

If I introduce a single alert call for debugging,
the target frame update works fine; otherwise never.

This occurs with modern versions of both IE and
Mozilla. Here's the JS:

var loaded = null;
....

function checkload() {return loaded ? true : false;}

function update() {
if ( !newwin || newwin.closed ) {
newwin = window.open('/path/some.html', '','query' );
newwin.focus();
}
....
if ( checkload() ) {
//alert("loaded=" + loaded); // loads fine
clearTimeout(window.id);
} else {
window.id = setTimeout('checkload()', 1000);
}
newwin.frames[1].location.href='/path/cgi/some.cgi?qrystr';

Any thoughts appreciated.

Rgds,

If the new window is closed or if its reference in memory is inexistent,
then you create it: then why would you need to focus it if it is going
to be created?
}
...
if ( checkload() ) {
//alert("loaded=" + loaded); // loads fine
clearTimeout(window.id);
} else {
window.id = setTimeout('checkload()', 1000);
How/what is the code suppose to do with id here? there is no id property
for window.
}
newwin.frames[1].location.href='/path/cgi/some.cgi?qrystr';

Any thoughts appreciated.

Rgds,

Can you provide an url where this problem happens? An url for the
[path]/some.html and for its opener. As filed, it's very difficult to
guess what's needed ..

Hm, the update will occur in that window so I wanted it to
be visible. As I recall, it remains submerged sometimes
without the focus call.

}
...

clearTimeout(window.id);

window.id = setTimeout('checkload()', 1000);

You're right -- I forgot that declaration.

}

...

Fortunately, I made a change to setTimeout and everything is fine.
Here's the change:

window.id = setTimeout('update()', 1000);

This works every time. I'm not sure why -- the scope makes more
sense to me as I think about what's happening though.

Thanks,

The window is to be created, not updated. A newly created window is not
"submerged" like you say. It "pops" up on top of all other windows.

True, perhaps, something else occurred to cause the newly
created window to lose focus. At any rate, the focus of
the newly created window wasn't the real issue and the problem
has dissolved with the change to SetTimeout.
