Öppna i nytt fönster

Hej!!
Jag har detta script på min hemsida, men problemet är att det inte öppnar i ett nytt fönster. Hur gör man nu då?

       <script language="javascript">

var i, needlen = needle.length, haylen = haystack.length;
for (i=0; i<=haylen-needlen; i++) {
if (needle == haystack.substring(i,i+needlen))
return i;

return false;
