Board index » javascript » KeyPress Events in IE

Is there any way in JavaScript to determine which key has been pressed
during any of the key-press, key-down, key-up events in IE6+? It
appears the "which" property only works for Netscape.

I can help you with this!
In netscape, it is evt.which. In IE, it's event.keyCode. Here's a snippet
of code I use:
function onlyNumbersXB(obj, e, mask) {
var keyCode;
var returnVal = false;
if (window.event) {
e = window.event;
keyCode = e.keyCode;
} else {
// a key, such as delete, was pressed; let it pass through
if (e.keyCode == e.which) keyCode = null;
// else if not a char we don't know what this is; let it pass through
else if (e.charCode != e.which) keyCode = void 0;
// else a char - set it
else keyCode = e.which;
}
// do whatever you want based on keyCode...
// now for the return
if (window.event) {
e.returnValue = returnVal;
return returnVal; // not really necessary but I'm trying to get
Safari to work
} else
return returnVal;
}
}
This method is invoked on a text field, onKeyPress='return
onlyNumbersXB(this, event, mask)'
My problem, as posted elsewhere, is getting Safari to behave itself. It has
window.event and behaves that way. It sets e.returnValue appropriately. It
still doesn't recognize "false" and let's the key pass.
Anyone?

checking that the event is cancelable by checking the event's W3C DOM
(boolean) - cancelable - property? Also (assuming that is no-go) have
you considered trying to cancel onkeydown and/or onkeyup instead of (or
in addition to) onkeypress?

"combined with if the event is cancelable". What would combining the two
do?
went with onKeyPress.
Canceling keystrokes is something that whole documents have been written
about regarding IE and Netscape. I can't believe that I can be the only
person struggling with this with Safari...

boolean - cancelable - property and it is false then there is not much
point in calling its - preventDefault - method as the event cannot be
cancelled.
Yea - except we have problems with onKeyDown and Netscape 7.
That's why we went with onKeyPress.

Validating user input as they type is problematic at best, clear
