Cross browser attach event function and firefox events

Hi,
I am trying to work out how to access the event object in firefox
under two conditions -
1) Attaching event handlers in javascript, not html.
2) The event handler requires parameters in addition to the event
object.

Here is an HTML page that demonstrates the problem. Notice that it
works in IE but not firefox.

<form action="">
 
<p><input id="testBox" type="text" /></p>
 
</form>
 
<script type="text/javascript">
 
function XBrowserAddHandler(target,eventName,handlerName)

{

if ( target.addEventListener )

target.addEventListener(eventName, handlerName, false);

else if ( target.attachEvent )

target.attachEvent("on" + eventName, handlerName);

else

target["on" + eventName] = handlerName;

}
 
var y = 3;
 
var txtTestBox = document.getElementById('testBox');
 
XBrowserAddHandler(txtTestBox, 'keyup', function()

{ myFunctionRef(y) });
 
var myFunctionRef = function myFunction(x, e)

{

var keyCode;
 
if (!e && window.event)

e = window.event;
 
if (e)

keyCode = (window.Event) ? e.which : e.keyCode;
 
alert('You pressed: ' + keyCode + '. Event object is :' + e + '. x

is: ' + x);

}

</script>
 
</body>
