Code für komplexe Validierungen
Der komplexe JavaScript Code bietet eine API für
Custom-Validators. Die API weicht etwas
von der PHP API für Custom-Validators ab.
Im Verzeichnis "HTML_OOH_Form/js/" befindet sich
die Datei "JS_README", die einen ersten Einblick in die Details
der JavaScript Programmierung gibt.

<?php
require_once('HTML_OOH_Form/form.php');
define('FORM_FILE_DIR', $DOCUMENT_ROOT . '/projekte/');
// alle File-Funktionen in den OOH-Forms benutzen die Konstante
// FORM_FILE_DIR
$code = implode('', file(FORM_FILE_DIR . 'HTML_OOH_Form/js/form_js_complex.js'));
$code = preg_replace('/\t/', ' ', $code);
printf("Komplexer Code [%d Bytes]:\n\n%s\n\n",
