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

SYNOPSIS
	 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 } );

       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.
