WWW::Mechanize::FormFiller::Value::Callback - Call Perl code to fill out a HTML form field


  use WWW::Mechanize::FormFiller;
  use WWW::Mechanize::FormFiller::Value::Callback;

  my $f = WWW::Mechanize::FormFiller->new();

  # Create a default value for the HTML field "login"
  # This will put the current login name into the login field

  sub find_login {
    getlogin || getpwuid($<) || "Kilroy";

  my $login = WWW::Mechanize::FormFiller::Value::Callback->new( login => \&find_login );
  $f->add_value( login => $login );

  # Alternatively take the following shorthand, which adds the
  # field to the list as well :

  # "If there is no password, put a nice number there
  my $password = $f->add_filler( password => Callback => sub { int rand(90) + 10 } );


This class provides a way to write a value returned by Perl code into a HTML field.

name [NEWNAME]

Gets and sets the name of the HTML field this value corresponds to.

value FIELD

Returns the value to put into the HTML field.


None by default.
