Thank you, I see what you are saying and will test the jQuery examples.
Ideally, I'd like to predefine the validation code and just specify a
mask when the field is declared in the Field statement (DRY). Then
forms would inherit the value and use the appropriate jQuery code for
those fields.
Thanks!

web2py does this automatically for some fields (integer, float, decimal). It
prevents you from typing invalid chars and also validates serverside for
security. It very easy to add other
types of client-size typing restrictions by using the examples. For example for
integer:
jQuery(document).on('keyup', 'input.integer', function () {
this.value = this.value.reverse().replace(/[^0-9\-]|\-(?=.)/g,
'').reverse();
});

Hello. I'm just starting to dig into web2py. One thing I really want
is field input masks ala Visual Foxpro, to prevent users from entering
invalid characters rather than validating afterwards and telling them
they made a mistake.
For example, if a user types alpha characters into a numeric-only field,
they do not even appear. A field that is uppercase alpha would convert
a lowercase "a" to "A" as the user types. VFP input masks could do
complex things with combinations of wildcard and static characters, like
"999-999-9999", where the 9 allows a numeric digit, but the dashes are
automatically inserted in the string when the user reaches that point.
Some searching did not find anything concrete. Is there a plugin or
some other standard way of doing least basic input formatting as the
user enters data in a field?
Thanks!
