MAC onkeypress problem

[Simon Wigzell]

I have a simple function whose purpose is to return false onkeypress and
then that character should not appear in the text field.
On any browser I have tried on a PC the return false means that the key
pressed character won't appear in the text field. On a MAC with Safari it
will. Any idea how I can prevent the character from appearing in the text
box for MAC Safari? This link is to a stripped down version that
demonstrates the problem:

Don't use 'return false'.

What you are trying suggests that you want to look at keycodes and
prevent presses of certain keys. That strategy is nearly always doomed
to failure - it is much better to look at the actual text entered and
advise where it differs from what you want.

Remember that sniffing keypresses doesn't restrict what a user can enter
into the field - there are a couple of ways to enter any value I like
into your field even in browsers where 'return false' prevents
keypresses. And if scripting is disabled or not available, your script
can't do anything.
