Try this modification:

function mouseclick(e) {
var what = e.target || e.srcElement;
if (what) alert("I was clicked on " + what.tagName);
}
[...]
<body onclick="mousec lick(event)">

I'm not near an IE box right now, but I think to keep IE happy you'll
need to add the above line before:
var what = e.target || e.srcElement;

[...]

I'm playing in Safari at the moment, it seems to support a bit of both
Firefox/Netscape and IE (but often neither...) so I can't test it in
IE.

You may only need the extra line if you don't pass 'event' with the
onclick call.

Yes, event handlers work in Netscape, depending on the Netscape version
not all event handlers specified in HTML 4 might work but with Netscape
6/7 there is certainly support for HTML 4 and for DOM Level 2 Events.
<HTML><SCRIPT LANGUAGE="JScri pt">
function mouseclick() {
alert("I was clicked on " + window.event.sr cElement.tagNam e);
Have you checked the JavaScript console? It probably shows you that
window.event
is undefined or not an object with Netscape 6/7
<BODY onclick="mousec lick()">

so the problem is not that the onclick handler is not being fired but
that your script being called then throws an error.
You can pass the event object to a function e.g.
<body onclick="mousec lick(event);">
and then you need to process that argument in the function e.g.
function mouseclick (evt) {
and then you need to be aware that properties of the event object differ
in IE and in Netscape, IE docs are here:
<http://msdn.microsoft. com/library/default.asp?url =/workshop/author/dhtml/reference/objects/obj_event.asp>
Netscape 6/7 implements the W3C DOM as given here:
<http://www.w3.org/TR/DOM-Level-2-Events/events.html#Eve nts-Event>
<http://www.w3.org/TR/DOM-Level-2-Events/events.html#Eve nts-UIEvent>
<http://www.w3.org/TR/DOM-Level-2-Events/events.html#Eve nts-MouseEvent>

You already got an answer showing to access target with Netscape (or
other browser supporting that) and srcElement with IE (or other browsers
supporting that).

And Dietmar had
<body onclick="mousec lick(event)">
in his answer so your line is not needed with his solution.

The script certainly would error if executed in Netscape/Mozilla, but
would they execute script specified as language="JSCRI PT" in the first
palace?

In addition to my code, see Richard's answer. Instead of

<SCRIPT LANGUAGE="JScri pt">

(which is MSIE-proprietary) you should use

<script type="text/javascript">

to have your code executed in both Netscape7 and MSIE (and
other browsers). A complete example document would be:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Script-Type"
content="text/javascript">
<meta http-equiv="content-type"
content="text/html; charset=ISO-8859-1">
<title></title>
<script type="text/javascript">
function mouseclick(e) {
var what = e.target || e.srcElement;
if (what) alert("I was clicked on " + what.tagName);
}
</script>
</head>
<body onclick="mousec lick(event)">
<H1>Welcome!</H1>
<P>This is a very <B>short</B> document.
</body>
</html>

Good catch, Mozilla indeed ignores such a script block.

FireFox event model failure

My original idea of two trains, however pictural it was, appeared to be wrong. The truth seems to be even more chaotic.

By carefully studying fromElement and toElement properties, one can handle events on any point of their way up. NN/FF implements a "Russian hills" style: mouse events go first up->down (window->deepest...
