Calling a controller from javascript function

Hi,

Is it possible to call a Rails controller from a javascript function?

This is part of my code:
<%= start_form_tag({:action=> "index"}, {:onsubmit => "clickResult();
return false;", :autocomplete => 'off'}%>

The clickResult() function:
function clickResult() {
  window.location = "http://myblog.com/post/" +
document.getElementById("Highlight").firstChild.id;
}

I want to call this function from javascript because now I have to
hard-code the url:
def permalink
    @post = Post.find(params[:id])
end

Any ideas?

This might work, I haven't tested it at all, but it seems like it should
do the trick...
The main addition is the 'remote_function' action, which performs a Ajax
request to
the given parameters

<%= start_form_tag({:action=> "index"},
                   {:onsubmit => update_page{|page|
                                   page.call('clickResult')
                                   remote_function(:url => {:controller => 'some_controller),
                                                   :action => 'permalink',
                                                   :id => post.id})},
                    :autocomplete => 'off'})%>

The clickResult() function:
function clickResult() {
  window.location = "http://myblog.com/post/" +
document.getElementById("Highlight").firstChild.id;
}

Sorry for the syntax error!
here's the fix

<%= start_form_tag({:action=> "index"},
                   {:onsubmit => update_page{|page|
                                   page.call('clickResult')
                                   remote_function(:url => {:controller => 'some_controller',
                                                            :action => 'permalink',
                                                            :id => post.id})},
                    :autocomplete => 'off'})%>
