NAME
JavaScript::DataFormValidator - JavaScript form validation from a Perl
Data::FormValidator profile
SYNOPSIS
This module helps with setting up a JavaScript validation for a form
using Data.FormValidator, a JavaScript port of Data::FormValidator. A
key feature of this system is that it allows you to use the *exact same*
validation profile for both Perl and JavaScript validation.
You should read the docs for the JavaScript implementation for some
Here's an example with HTML::Template syntax:
<script type="text/javascript" src="../JSAN/Data/FormValidator.js"></script>
<!-- tmpl_var dfv_profile -->
<form action="/foo" <tmpl_var js_dfv_onsubmit > >
<!-- ... ->
</form>
And then back in your perl code...
use JavaScript::DataFormValidator;
my $t = HTML::Template->new_file('foo.html');
$t->param(
dfv_profile => js_dfv_profile( 'my_form' => {
required => [qw/email first_name/],
optional => 'last_name',
constraints => {
email => 'email',
}
}),
js_dfv_onsubmit => js_dfv_onsubmit('my_form');
);
REQUIREMENTS
The Data.FormValidator JavaScript file must be copied to your server so
that you can call it. Download the latest version from here:
js_dfv_profile( $profile_name => \%profile_hash );
$dfv_profile_in_js = js_dfv_profile( $profile_name => \%profile_hash );
Takes a named Data::FormValidator profile in Perl, and returns a
representation of it in JavaScript, for use with the Data.FormValidator
JavaScript module.
STATUS
Hopefully, it's done. It's very simple code.
However, the API may break and change in the first weeks after the the
release as I get feedback. I'll plan to at least make a new release to
remove this notice once things seem stable.
js_dfv_onsubmit($profile_name);
$onsubmit_code = js_dfv_onsubmit($profile_name);
Returns the Javascript snippet to put in your <form> tag to call the
basic "check_and_report()" JavaScript validation function.
FUTURE DEVELOPMENT
This module is mostly released as a demonstration of how to integrate
with the Data.FormValidator JavaScript project. For anything more
complicated, it will probably be easier to use this source code as
starting point for a custom solution.
