NAME
WWW::Mechanize::FormFiller::Value::Random::Chars - Fill characters into an HTML form field
SYNOPSIS
use WWW::Mechanize::FormFiller;
use WWW::Mechanize::FormFiller::Value::Random::Chars;
my $f = WWW::Mechanize::FormFiller->new();
# Create a random value for the HTML field "login"
my $login = WWW::Mechanize::FormFiller::Value::Random::Chars->new(
login => set => 'alpha', min => 3, max => 8 );
$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 random one out of the list there
my $password = $f->add_filler( password => 'Random::Chars' );
DESCRIPTION

new NAME, LIST
Creates a new value which will correspond to the HTML field "NAME". The "LIST" is the list of arguments passed to
Data::Random::rand_chars. If the list is empty, "set => 'alpha', min => 5, max => 8" is assumed.
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.
