Yet another javascript function?

[vongrunt]

This probably doesn't belong to useful tips, so here comes a question: what does the following function?

<script language="javascript">
function blah()
{	with( arguments.length? arguments[0]: document.body)
		for (var i=0; i< childNodes.length; i++)
			with(obj = childNodes[i])
				nodeType==3? nodeValue=nodeValue.split(" ").reverse().join(" "): blah(obj);
}
</script>

Hint: paste it into any page you want (longer, more complex = better) and call from body onload.

Without running it (but scanning the function) it looks like it recursively parses the document, reversing the positions of all words (seperated by spaces) - not the letters that make up the words... just the words (as they appear in a sentence).

I ran the code on NS7 - page is a very long credit application - didn't do anything. Page looks the same with or without.

There's always a better way. The fun is trying to find it!

I noticed that too - on some pages, in IE/Moz. Some sites are all in frames, some redefine window.onload handler on-the-fly... many possible reasons. On this page though (saved locally), works fine .
