To script event handling beyond IE you need to learn the DOM event model.
google it, or start here-

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.dtd">
<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="codeNum(event)"/>
</body>
</html>

[/HTML]

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:

Expand|Select|Wrap|Line Numbers

alert(event.keyCode);

You're actually doing this (because 'with window' is assumed in JavaScript):

Expand|Select|Wrap|Line Numbers

alert(window.event.keyCode);

Instead, you want to use charCode:

Expand|Select|Wrap|Line Numbers

 
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.

In Mozilla using "event.which" works with almost all chars, but an example of one that it doesn't works is the TAB char,
if your code like this:

Expand|Select|Wrap|Line Numbers

 
........

if(event.which){

    ..........

}else{

    ..........

}

........

for the char TAB , i'm not sure why, "event.which" is eq 0 so it's evaluated as false!

I suggest to use "event.type", it returns the event occured...
