Hi,
okay, ich versuchs' nochmal...:
<html>
<head>
<style type="text/css">
<!--
.antwort {background-color:blue;
color:white;
font-weight:bold;
font-family:Arial;
font-size:12;}
-->
</style>
<script language="javascript">
function antwort(){
if(document.formular.auswahl[0].checked){
document.getElementById('antwort1').style.backgroundColor='red';
document.getElementById('antwort2').style.backgroundColor='blue';
}else{
document.getElementById('antwort1').style.backgroundColor='blue';
document.getElementById('antwort2').style.backgroundColor='red';
}
}
</script>
</head>
<body>
<form name="formular">
<input name="antwort1" id="antwort1" class="antwort" size=25><br>
<input name="antwort2" id="antwort2" class="antwort" size=25><br>
<input type="radio" name="auswahl" value="a1" onclick="antwort()">1<br>
<input type="radio" name="auswahl" value="a2" onclick="antwort()">2
</form>
</body>
</html>
Das hat zu funktionieren.
Ciao
Andreas
