javascript redirect to new window
===

I have this code that redirects to a page based on the value of a dropdown list:

    <Script language="JavaScript">
    function goto(form) { var index=form.select.selectedIndex
    if (form.select.options[index].value != "0") {
    location=form.select.options[index].value;}}
    //-->
    </SCRIPT>

How do I make that open in a new window?
