You can use the OnKeypress javascript event
Evaluate the keypress on the function

Are you trying to ask a question, or make a statement? It seems the
latter. In either case, it would be nice to actually present valid markup.

The best approach, in my opinion, is to not even try to prevent
keystrokes. This can lead to confusion or irritation if the user doesn't
realise that a keystroke has been ignored, and before it's suggested,
alerting the user to it isn't a good solution. That'll lead to more
frustration.

Instead, validate the field after the user has finished entering their
value. It's far more kind to the user and more reliable.
