finding the parent of an iframe

Copy linkTweet thisAlerts:
Jun 24.2008

hello everyone.
I want to traverse all the way up to the parent of all the iframes in my page.
When i use
<script laguage=”javascript”>
par=window.location;
ch=parent.par;
document.write(ch);
</script>

it will print out the parent. However when run within an iframe, it will just print out “undefined”.

Ex: page1 has the script in it
page2 has an <iframe src=”page1.html”>
page3 has an <iframe src=”page2.html”>

when on page1.html it prints correctly. When on page2.html or page3.html it will print out undefined.

What is the matter?

@gil_davisJun 24.2008 — To get "all the way up", use window.top.

Using document.write() in a function like that will wipe out the document. Until you know what you are doing, use alert() instead.
