Changing visibility of Iframe

[Wutu]

Hey world! I'm REALLY new to javascript and i wanted to make a simple script that shows or hides an Iframe. Here's an example of what i think would work but doesn't:

<a href="javascript:showHide()">Show or Hide Frame</a>
<iframe src="http://www.google.com" name="google" id="google" style="visibility:visible"></iframe>
<script type="text/javascript">
function showHide(){
   if (document.getElementById("google").style.visibility == "visible"){
      document.getElementById("google").style.visibility == "hidden";
   } else if (document.getElementById("google").style.visibility == "hidden"){
      document.getElementById("google").style.visibility == "visible";
   }
}
</script>

Can someone please tell me what's wrong???

You have errors in your script (double equal signs for assignment operations), but the fact that the IFRAME source is an external domain may make it impossible for you to control the IFRAME via JavaScript.

How about if i put a div tag around the iframe and access the div thru javascript instead of the iframe?

Sounds good.
