Firefox/Mozilla and window.event.keyCode

[Perttu Pulkkinen]

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?

function toCurrency(val)
{
if(val <0)
{ euros = Math.ceil(val); cents = Math.abs(Math.ceil(val*100) -
euros*100); }
else
{ euros = Math.floor(val); cents = Math.floor(val*100) - euros*100; }
if(cents <10) cents = "0" + cents;
return euros +"." + cents;
}

parsedvalue = parseFloat(ele.value);

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.
IIRC it also supports the old which property (event.which).
