In the popup, you can refer to the opener window with the property
"opener"; before closing your popup, you just have to set the
location.href property of the opener to the new location.

Add the following in your popup:

---
<script type="text/javascript">
//write the close button
//but only if it can be used successfully
if(opener && self.close) {
document.write(
"<input type='button' "+
"value='Clo se' "+
"onclick='" +
"opener.locatio n.href=\"http://jibbering.com/faq/\";"+
"self.close();" +
"'"+
">"
);
}
</script>

Javascript is indeed case-sensitive, however the HTML attribute language
is not - and it's actually deprecated, so don't use it, use
type="text/javascript" instead.

That's just a "mailto:user@do main.com" action for the form. However the
technique changes a bit from above:

---
<script type="text/javascript">
function validate(frm){
if(opener) {
opener.location .href="http://jibbering.com/faq/";
}
if(window.close ) {
setTimeout("win dow.close()",1) ;
}
return true;
}
</script>

<form action="mailto: foo@bar.com"
onsubmit="retur n validate(this)" >
<input type="text" name="foo">
<input type="submit">
</form>
---

Note that the techniques exposed, while maybe acceptable for a personal
website, would not be used for a commercial one, since they have too
many inherent flaws:
- they rely on popup window, which can be affected by popup-blocking
software,
- they rely on mailto:, assuming that the user has a mail agent
configured (which is not always the case, many people just use web-based
mail agents) - ideally the mail should be built and sent server-side
(google for formmail).

HTH
Yep.

Really? What things?

Well, you have put in the hard yards..
Did you *read* *it*, or just glance
over it?

Pop-Ups.. Your app. is already sunk.

They do work, OK, in some browsers, but
whoever deploys such broken methods must
take special pains to explain to browsers
why your links are not doing anything in
there wonderfully current and up to date
IE with SP 2.

Somewhere late last millennium.
<script type='text/javascript'>

You can define functions in the <head>
and call them in the <body>. Actually
you can define methods all over the place,
but it makles most sense to collect them
in one place, either in the <head>, or
in an external file.

No. JS is generally not case sensitive.

Now, ..given I've been up 28 hours, I better
leave the important stuff for the gurus.

Over and ..snore..

Blame it on the lack of sleep. JS is very case-sensitive. Its the HTML
tags that are not. :-)

Aha! Thank you. Personally I allways
use correct case with JS commands (as
well as I understand the nomenclature)
and string comparisons, for the simple
reason it becomes easier for me to read.

Lucky for me (and the OP) you were paying
attention. ;-)
