title: Rails helper to call remote upon completion of event?
body: <p>I'm collecting latitude and longitude from Mobile Safari with some JavaScript code. After collecting the information from the browser, I want to update the location with an AJAX request. Is there a helper or otherwise simple way to do this with Rails/Prototype or will I have to do an XMLHttpRequest? I only see <code>link_to_remote</code>, <code>periodically_call_remote</code>, and <code>form_remote_tag</code> in the PrototypeHelper API.</p>
