Rails Ajax Form Disable Submit Button

I am having a little t开发者_如何学Gorouble figuring out how to disable the submit button in rails when a form is submitted. It works fine with javascript disabled and the ':disable_with' symbol in the 'remote_form_for#submit' function but cannot figure it out when submitting via ajax. Any thoughts? Using rails 2.3.5 and ruby 1.8.7.

You can hide the submit button when the request is made and show a loading image while the request is running. For example in a form_remote_tag:

<% form_remote_tag :url => "/some_url", 
:loading => "$('submit_span').toggle(); $('loading_span').toggle();", 
:complete => "$('submit_span').toggle(); $('loading_span').toggle();" do %>

-- FORM CONTENTS --

  <span id="submit_span">
    <%= submit_tag "Submit" %>
  </span>
  <span id = "loading_span" style = "display: none;">
    <%= image_tag("loading.gif")%>
  </span>
<% end %>

When the request completes (Success OR Failure) you unhide the submit and hide the loading span.
