// alpha characters, accept spaces
// required.add('[ FIELDID ]', 'ALPHASPACE');
// numeric characters, no spaces
// required.add('[ FIELDID ]', 'NUMERIC');
// numeric characters, also accepts +-.
// required.add('[ FIELDID ]', 'NUMERICPLUS');
// alpha and numeric characters, no spaces
// required.add('[ FIELDID ]', 'ALPHANUM');
// alpha and numeric characters, accept spaces
// required.add('[ FIELDID ]', 'ALPHANUMSPACE');

// NOTES:
// [ FIELD ID ] = REPLACE WITH ACTUAL FIELD ID VALUE
// example: <input type="text" name="THIS" ID="THIS"> = THIS

// to specify your own regular expression,
// enter the literal regex as type
// example: required.add('fieldid', '^[0-9]{3}$');
