Try, IE7 & FF2 tested:

keys with keyCode 48 to 57 need the shiftkey in addition to get a number
from alpha keyboard
- works with Safari
- not with F2 who return a keyCode for the shift's key
(not in the allowed plage :-( )

keys from numeric keyboard aren't more allowed ... ! :-(

But I can tape : @ & $ €

And no more backspace ... tab ... enter ... :-(

function IsNumeric(e) {
var c = e.keyCode? e.keyCode : e.charCode

alert('Only Numbers, please.');
return false;
};
</script>

This will not prevent pasting alpha strings!!!!!

Only if you use menu (and not use keyboard shortcuts)

It is a bad idea anyway, as it interferes with typing habits.

Better test the string onsubmit.
