Redirect with external javascript? Do I get banned in google?

I have to use this option ...

[foy]

So I use a javascript within my optimized pages that looks like this

var str1="window.";
var str2="location=";
var str3="'site.html'";
eval(str1+str2+str3);

and I put this into into another folder and link it to the pages.

Does google accept this method and spiders the sites anyways?

I'm not spamming nor faking content since I provide the users with the content that they were looking for when they get redirected but for some reason I had to make other pages that redirect to the original ones, so is this okay?

Google ignores Javascript, then it will not spider your redirected pages.
Maybe you will need some text links in the page that launch the script.
