An article from ParticleTree mentions a simple and effective solution that doesn't involve AJAX at all, but does cause a file to download without the user leaving the current page:

<form id="super_form" method="post" action="/file/">
    <input type="hidden" id="download" name="download" />
</form>

$('download').value = 'top10';
$('super_form').submit();

This doesn't directly answer your question about how to have a file download via an AJAX request, but I think this will give your end-user the experience you're looking for.
