javascript per aprire un div

[cavicchiandrea]

Prova cosi:

<script language="javascript" type="text/javascript">
function showhide(id){
var el = document.getElementsByTagName("div")
obj = document.getElementById(id);
for(var i = 0; i<el.length; i++){ 
if (el[i].getAttribute("id") == id && obj.style.display == "none"){
obj.style.display = "";
} else {
obj.style.display = "none";
}
}
}
</script>
