I'm trying to open a div with a jump to the anchor. The opening part is working but it's not jumping to the named anchor

This is my script:

<script type="text/javascript">
    function spoil(id){
        if (document.getElementById) {
            var divid = document.getElementById(id);
            divid.style.display = (divid.style.display = 'block');
            window.location = '#' + id;
        }
    }
</script>

<a href="http://example.com" onclick="spoil('thanks');" title="hello">
    <img src="images/gfx.png" alt="world" width="300" height="300"/>
</a>

Any ideas what's wrong with it? Cheers.
