1/. Can anyone tell me why renaming a function from 'update()' to
'form_update()' makes Safari work when it didn't before?
2/. I would LIKE if possible, to do the following.
User is filling in a BIG form. MYSQL/PHP generated. he finds that the
option he needs in a select statement isn't there, and needs to be added
via a different form.
I can easily spawn a new window to do this, but what I need to happen is
- new window opens in NEW WINDOW - not new tab..even if that's how the
browser is configured.
- on shutting down new window..yea even unto clicking on it's corner and
saying 'close' , the main program window can be forced to reload its
data, to pick up the changes.
I am very unsure of inter-window communications, and could use any
pointers...

Hi,
First question: I have no clue.
Safari? I gave up on Safari and JavaScript a long time ago.
Maybe Apple upgraded it to a better browser lately?

As far as I know, the tabbed opening of a new window only happens when
you do not give dimensions.
If you do, it opens a real new window (not tabbed).
Could open in tab:
window.open("in dex.php","testi ng");
Will NOT open in tab:
window.open("in dex.php","testi ng","width=300, height=300");

Have a look at the unOnload event handler.
You can write something like this:
in popup window:
<body onUnload="refre shDaddyPlease() ;">
<script type="text/javascript">
function refreshDaddyPle ase(){
opener.location .reload(true);
}
</script>
The true in reload(true) means force reloads, even if the http-header
If-Modified_since says otherwise.
>

Well, basic inter-window communication is simple.
eg:
[from openerpage]
var myRefToNewWindo w = window.open("in dex.php","testi ng");
Now you can use myRefToNewWindo w whenever you want to address the new
window. You can also call its javascript functions, eg:
myRefToNewWindo w.someFunction( "testing");
From the popup window, simply use the keyword 'opener' to find the
window that did it.
Good luck!

1/. Can anyone tell me why renaming a function from 'update()' to

Not without the context. The balance of probability is that you were
referring to the function from an event handler generated from an
intrinsic event attributer and the scope chain that the browser
generated for the event handling function it built from the attribute
value included an object with an - update - property above the global
object.
2/. I would LIKE if possible, to do the following.

Not in the sense of expecting an attempt to open a new window to be
successful.
but what I need to happen is
- new window opens in NEW WINDOW - not new tab..
Too late. The new window/tab distinction is (where available)
exclusively under user control.
even if that's how the
browser is configured.
Hard luck.
- on shutting down new window..yea even unto clicking on it's
corner and saying 'close' , the main program window can be
forced to reload its data, to pick up the changes.
So that is two inevitable HTTP request/response pairs and two sets of
processing HTML into displayed forms. In which case why not have the
existing window show the new form and then return to the old form when
it is submitted (with the data from the old form stored in the user's
session on the server in the interim)?
I am very unsure of inter-window communications, and could use any
pointers...
Avoid it like the plague.

Well, that clears it all up then.... NOT.

I did those tests on ff2 and ie7, you know, and I saw the results.

No, I did not need to. I used very similar code more often than you can
imagine.
Why don't you explain why you think it is wrong?
Because the correct explanation was already given by another person in this
thread.
I did those tests on ff2 and ie7, you know, and I saw the results.
So? You have tested with a very small subset of Web browsers (you did not
even include a non-browser UA), and saw your assumption confirmed. Why
would that be confirming your assumption for the general case? Don't answer
-- it does not.
Don't get me wrong, I don't question your experience with javascript.
I know you know a lot, but your educational abilities leave somewhat to
be desired.
Since when is this a J(ava)Script school? Am I being paid to sacrifice
free/business time to teach someone?
You might throw in a little more, like: "but it is not RFC xxy" or
"doesn't work like that in Safari/opera/Lynx".
For example, it does not work with Firefox 2.0.0.6 when the Tab Mix Plus
extension is installed and appropriately configured.

Some common sense would suit you.
Don't get your hopes up, he has been told that for about 3-4 years now.

If you are going to ask people for advice on a subject where design and
implementation decisions should be largely context driven it would be a
very good idea if you stated the real context along with the questions.
Otherwise you are just wasting people's time. It is the case that this
group's FAQ sates that the default assumption about the context will be
that questions asked relate to public web use if not stated otherwise.

response is practical.

You state that you did not want the 'new window' opening in a new tab.
You can take no action that will prevent that (even on the small sub-set
of browsers that interest you) as the users of some of those browsers
have an absolute veto on the outcome of window opening attempts. The
practical advice is to design a system that does not need to be opening
new windows, and in a controlled intranet context there are at least a
couple of ways of achieving that.
