B<validator tag> |
|
|
|
Some elements that accepts user input can contain a "validator" tag that, |
|
when surrounded by "sub { my $helper = shift; my $state = shift; my $element = shift; my $val = shift " |
|
and "}", where "$val" is the value the user entered, will form a subroutine |
|
that when called will verify whether the given input is valid or not. If it |
|
is valid, the routine will return a false value. If invalid, the routine |
|
will return an error message to be displayed for the user. |
|
|
|
Consult the documentation for each element to see whether it supports this |
|
tag. |
