Hallo,
habe ein Formular mit mehreren Optionsfeldern. Der User soll gezwungen werden davon mindestens eine Option auszufüllen. Wie realisiere ich das am besten? Hier der code:
<!-- Form validation:
<head>
</head>
<body>
<form name="testform" onSubmit="return validate()">
Name:<input type="text" size=30 name="Name">
Age:<input type="text" size=3 name="age">
<input type="submit" value="Submit">
</form>
</body -->
<html>
<head>
<title>test anfrage</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<style type="text/css"></style>
</style>
</head>
