Changepage function considered cloaking/rediret?

Lost one of my page rankings soon after

[eWhisper]

I don't keep a close eye on the G section as I've had pretty steady rankings for a while.

Several of our competitors started framing my site, so I added the below script to the homepage.

Within a week of this script being added, the page lost a few top 10 rankings.

Now I know there are many variables that go into ranking, and it could be coincidence - but since I'm not sure - thought I'd ask the experts if this could cause a penalty.

Thanks for the help.

<SCRIPT LANGUAGE="JavaScript">
<!--
setTimeout ("changePage()", 0);
function changePage()
{
if (self.parent.frames.length!= 0)
self.parent.location=document.location;
}
//-->
</SCRIPT>

*bump*

one of the many experts around here must be able to answer this question very easily.

does google think of the changepage function as any type of spam or illegal redirect?

eWhisper,

I don't know about your method, but I've used this frame-buster for years with no ill effect:

<script language="JavaScript1.1" type="text/JavaScript"><!-- // hide from old browsers
if (parent.frames.length > 0) top.location.replace(document.location); // Escape from any referring site's frame, but preserve one-click "Back". --></script>

Thank you, I'll have to try it out and see what happens.
