Capture keypress inside a textarea

Hans

How do I capture the keycode inside a <textarea> in NN6+ and IE5.5+? I don't
want to add add document.keyPress function because I only want this to
occure when a specific textarea is selected and not fire for every keypress
in the entire document.

<textarea onkeypress="captureKeys();"....

but I cannot get a reference to the current event so i can ask for the
keyCode. In IE I can check the event.keyCode inside my function captureKeys
but this is not possible in NN6+.

Regards

Simply use
<textarea onkeypress="return captureKeys(event);"
and then
function captureKeys (evt) {
var keyCode = evt.keyCode ? evt.keyCode :
evt.charCode ? evt.charCode : evt.which;
if (keyCode == ...) {
// cancel key:
if (evt.preventDefault) {
evt.preventDefault();
}
return false;
}
return true;
}
