[html-formfu] Clientside validation

[Moritz Onken]

  Hi,

I'm using the extJS framework in combination with formfu. It allows  
you to send the form data to your server and parses the returned  
messages and prints them next to invalid form fields. It is JSON  
based, but with a little bit of code you can easily return the formfu  
error messages usign JSON.

if ( $form->has_errors ) {
   $c->stash->{success} = 0;
   for ( @{ $form->get_errors } ) {
      push(
        @{ $c->stash->{errors} },
        { id => $_->name, msg => $_->message }
      );
}

this is a catalyst example. Make sure to set the view to JSON.
