Rails - Sep 2009 - (rails question) placing link_to inside javascript tags? Options

Hey everyone,
I''m wondering if anyone has tried to use the link_to function inside
<script> tags in a view? I''m using facebox to create a lightbox
effect
on a link. I want to place this inside a javascript function so I can
use it via a button in a js form. Here''s what I would like to do, but
I''m not sure if it''s possible. Has anyone done this before?
I''m
thinking I might have to dig into facebox to see how to pass what I
want using pure javascript. I''m not a javascript programmer, so a
rails approach would be easier for me.
Here''s what I would like to do...
<script type="text/javascript">
  function test(com,grid) {
    if (com==''Delete'') {
      confirm(''Delete '' +
$(''.trSelected'',grid).length + '' items?'')
    }
    else if (com==''Add'') {
      <%=facebox_link_to "+New Reading", :url =>
''readings/
new'', :method=>''get''%>;
    }
    else {
      alert(''Test'')
    }
  }
</script>
Any help is appreciated.
Chris
