Rails: submit (via AJAX) when drop-down option clicked

Question

What is the easiest and most graceful way to auto-submit an AJAX form when a drop-down box\'s option is selected? I\'m creating an administration page where the admin can modify

Answer 1

In Rails 3:

<%= form_for(membership, :remote => true) do |f| %>`
  <%= f.select :permissions, [['none', 0], ['admin', 9]], {}, :onchange => 'this.form.submit();' %>
<% end %>

Note that it's this.form.submit(); not onsubmit. And don't forget the Javascript semicolon.
