O’Reilly Amazon Hack

I am trying to use the Amazon hack from O’Reilly’s book, but my Google toolbar pop-up blocker keeps blocking it, even when I click popups okay.

Can this script be changed to open in same window?

[CODE]
<script language=”JavaScript”>
var searchURL = new

String(“http://www.amazon.com/exec/obidos/external-search/mode=blended&keyword=”);

var w = window.external.menuArguments;
var d = w.document;
var s = d.selection;
var r = s.createRange( );
var term = new String(r.text);

window.open(searchURL + term);
</script>
[/CODE]

Also in #JavaScript _↴
