Getting frame/iframe urls with javascript?

How i can get an frame "current" url or an iframe url with javascript?

 

.location property
on a normal page it is document.location
on frames frames['xxx'].location

 

I really don't know why this code is not working...

<script type="text/JavaScript">

function geturl(){
var url=document.getElementById("active").src;
document.getElementById("status").innerHTML=url;
alert(url);
      }

</script>




<div class=status id=status>Start Surfing...</div>
<script type="text/JavaScript">
geturl();
</script>

<iframe id="active" src="http://www.google.com" border=0 height=500 width=100%>

Code (markup):

 

Actually the Javascript is not seeing my IFRAME "active"

if i am doing an document.getElementById("active").style.display="none"; will not hide it, but if i will do an document.getElementById("status").style.display="none"; it will hide the status DIV...


Also things like window.frames[active].location='http://yahoo.com'; , will just not work...
