Something amis with passing a keyCode to a function

[Matthew]

Still getting my webfeet on in understanding the proper syntax for
crafting javascript statements. I've created this function that
ignores the code if the Tab key is pressed... oddly enough it works
just fine in IE and ignores the Tab key like I want it too, but in
Netscape it blows up.... I don't think the Tab key is being passed or
something else is amis. ???


<script type="text/javascript">
function showRemaining(formElement) {
if ((event.keyCode) != 9) {
var theForm1 = formElement.form;
var remainingDisplay = formElement.name + 'Remaining';
theForm1.elements[remainingDisplay].value = formElement.maxLength
- formElement.value.length;
}}
</script>




<input... onkeyup="javascript:showRemaining(this);"

Where does the event variable come from? (In IE, it is a global variable,
in most remining browsers and W3C DOM 2 Events, it is not).

I suggest making the event a parameter of the function, i.e.,
---
function showRemining(evt,formElement) {
if (evt.keyCode != 9) {
---

and then:

<input... onkeyup="javascript:showRemaining(this);"

<input ... onkeyup"showRemaining(event,this);">

No "javascript:" in front (why did you think it should be there?),
and pass the event to the function.
