how do I access the onKeyPress value?

I have the following javascript code in the HEAD section...

And I have the following line in a form on the page:

The problem is that I don't know how to access the value of the keypress that triggered the event.
Can anyone help me out here, JavaScript is not my forte...

The return value of a JavaScript event handler is usually used to indicate the disposition on an event, namely to perform or nor a certain action.
What are you trying to do?

If u want to know which key was pressed, then u can try this...
in the form

and in the script

hi
As Rajeshwari siad it will work but not in netscape so may u need cross-browser javascript , as IE and Netscape handle the javascript event in different format.So u need the common javascript for both browser.

look at this:

Thanks, all. That was very helpful - the information I was scrabbling for was the event.keyCode() method.
Is there an equivalent I could use for IE and NN? Or a resource I could look at to find examples of cross-platform js event handling?

if you looked at my link it shows the IE and NN Stuff, but look at this code
<html>
<head>
<script>
function checkTime(X) {
Str=X.value;
StrLen=Str.length;
StrT=Str.slice(StrLen-1,StrLen);
var StrRE1 = /^\d/;
var StrRE2 = /^[0-2]/;
var StrRE3 = /^:/;

if(StrT.match(StrRE1) && StrLen>1 && StrLen<6) {
if(Str.length==2)Str+=":";
X.value=Str;
if(Str.length==5){X.blur();return false;}
else return true;
}
else if (StrT.match(StrRE2) && StrLen==1){
return true;
}
else if (StrT.match(StrRE3) && StrLen==3){
return true;
}

else {
Str=Str.slice(0,StrLen-1);
X.value=Str;
return true;
}
}
</script>
</head>
<body>
<form name="P">
<input type="text" name="B" onkeydown="checkTime(this)" onkeyup="checkTime(this)">
</form>
</body>
</html>
There is one problem that I have with it, and I am going to try to fix, You can not edit it after it is changed!
