Firefox doesn't use the global window.event but the passes an event
object to the handler. However if you use just "event" it will work as
this will be the event object within your handler.

onkeypress="return onKeyCurrencyCheck(event, 'x')"

keyCode is also know by firefox, but if you use keypress you may check
for charCode.

can u elaborate this,
u mean to say mozilla doesnt require window.event,so in order to use that function we have to send event as a paramater.

iam a asp.net developer
iam using control
<asp:textbox >
when sending event as a paramter to the function,it is returning undefined for event.

Take this:

(Toggle Plain Text)

 
function numvalues(e){
	if(!e) e=event;e=e.keyCode||e.which;//b.b. TroyIII p.a.e
	if((e>57)||(e<48)) {alert("Only Digits Are Allowed!"); return false;}
	}
document.onkeypress=numvalues

You should use yourElement.onkeypress=numvalues instead!

p.s.: I'm not sure what were you thinking with the window.event.keyCode=null; , but I assumed you wan'ed to dissable it.
