Ebenen ausblenden

moin Momo :)
folgender Code tut genau das, was du dir wünscht (getestet mit IE und FF). Oder habe ich deine Anforderung falsch verstanden?

  
<script language="JavaScript">  
function auswahl() {  
var f = document.forms[0]  
 if (f.test.selectedIndex==1){  
    document.getElementById("us").style.display = "block";  
    document.getElementById("eu").style.display = "none";  
    document.getElementById("de").style.display = "none";  
 }  
 if (f.test.selectedIndex==2){  
    document.getElementById("eu").style.display = "block";  
    document.getElementById("us").style.display = "none";  
    document.getElementById("de").style.display = "none";  
 }  
 if (f.test.selectedIndex==3){  
   document.getElementById("de").style.display = "block";  
    document.getElementById("us").style.display = "none";  
    document.getElementById("eu").style.display = "none";  
 }  
}  
</script>  

[code lang=html]
<form>
<select name="test" onchange="auswahl();">
 <option value="0" SELECTED>sel...</option>
 <option value="1">us</option>
 <option value="2">eu</option>
 <option value="3">de</option>
</select>
</form>
<div id="us" style="display:none;">test us</div>
<div id="eu" style="display:none;">test eu</div>
<div id="de" style="display:none;">test de</div>
