caricare contenuto in un div

[markgrav]

mi dai un ultima mano xinoid

ho trovato questo script che mi servirebbe per fare quello che ti dicevo

ma nn capisco che cosè che nn lo fà funzionare

<script type="text/javascript">
/***Combo Menu Load Ajax snippet**/
function ajaxcombo(selectobjID, loadarea){
var selectobj=document.getElementById? document.getElementById(selectobjID) : ""
if (selectobj!="" && selectobj.options[selectobj.selectedIndex].value!="")
ajaxpage(selectobj.options[selectobj.selectedIndex].value, loadarea)
}
</script>

<form>
<select id="ajaxmenu" size="1">
<option value="page1.htm">Page 1</option>
<option value="page2.htm">Page 2</option>
<option value="subdirectory/page3.htm">Page 3</option>
</select>
<input type="button" onClick="ajaxcombo('ajaxmenu', 'contentarea')" value="Go" />
</form>

<div id="contentarea"></div>
