spinner in form tag?

Hello!
Is it possible to have a spinner in form_tag?

like:

<% form_tag :action=> 'list', do
         :loading=>"Element.show('spinner');",
         :complete=>"Element.hide('spinner');" %>

...
...
<% end %>

If not how could I do it?
Thank you!

I think you can implement spinner on Ajax requests only. So you are
calling form via Ajax request you can make spinner work.
