Try this modification:

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

ciao, dhgm

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.

Does Event handlers work in netscape.

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="JScript">
function mouseclick() {
alert("I was clicked on " + window.event.srcElement.tagName);

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="mouseclick()">

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="mouseclick(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/d.../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#Events-Event>
<http://www.w3.org/TR/DOM-Level-2-Events/events.html#Events-UIEvent>
<http://www.w3.org/TR/DOM-Level-2-Events/events.html#Events-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).

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

Thanks for your code. But its not working in Netscape, same problem

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

<SCRIPT LANGUAGE="JScript">

(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="mouseclick(event)">
<H1>Welcome!</H1>
<P>This is a very <B>short</B> document.
</body>
</html>

Good catch, Mozilla indeed ignores such a script block.
