To script event handling beyond IE you need to learn the DOM event model.
google it, or start here-
http://www.javascriptk it.com/domref/domevent.shtml
in firefox you can try this:
[HTML]
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dt d">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
<script type="text/javascript">
function codeNum(e)
{
alert(e.keyCode );
}
</script>
</head>
<body>
<input type="text" onkeydown="code Num(event)"/>
</body>
</html>
[/HTML]

actually in firefox guys its charCode not keyCode... keyCode is IE specific.

First things, first, IE handles events differently from other browsers. In IE, 'event' works because Internet Explorer attaches the last event to the window. So when you type:
You're actually doing this (because 'with window' is assumed in JavaScript): -
alert(window.event.keyCode);
-
Instead, you want to use charCode: -
function codeNum(e)
-
{
-
if(!e)
-
e = window.event;
-
if(e.keyCode)
-
alert(e.keyCode);
-
else
-
alert(e.charCode);
-
}
-
problem is in firefox event.keycode=9 returns error because event.keycode is a getter property. so i can't set tab event by assigning keycode= 9. is there any setter property of event.keycode by which we can assign any keycode to it?

Wait... you want to simulate a tab press?
Why not just use the focus method of the element you want to focus?
dear pbmods, my application creates field names on run time so i can't pass the next field name or can't move focus to the field by using its name.

and why not? add names to your elements.
and why not? add names to your elements.
IE provides "event.keyC ode" BUT
Mozilla provides "event.whic h"
Try this guys..

Are there any gotchas using if (event.keyCode==8)? I understand that
to represent backspace, but it doesn't work. I am running Windows XP,
using a typical keyboard - but no luck in detecting backspaces. Anyone

I have different functions that receive window.event as parameter. Functions
are used like this:
<input type="text" id="x"
onkeypress="return onKeyCurrencyCheck(ev, 'x')"
onblur ="onBlurCurrencyCheck(event, 'x')"">
Works very well with IE, but window.event and maybe window.event.keycode too
seems to be missing form firefox. Is there a workaround for this?

The following code works fine in IE but not Firefox.
It's a little script that zooms an image and resizes the window to fit.

Hello,
In an ASPX page I have a "Quit" button which make a simple redirect in
code-behind.
This button doesn't work no more since (I think) I moved from the framework
1.0 to 1.1
and it doesn't work only on IE! My ASPX page works in FireFox.
If the button doesn't work it's because of validators (and it worked with
the same code in v1.0).
