Yea, remote_form_for seems like it might work, but Im just not sure
how to pass the javascript array with this. Anyone have any idea?
This is what Im trying but it doesnt seem to work:
<% remote_form_for :appointment, @appointment, :url => {:action =>
"array"}, :with => "'data='+test()" do |f|%>
<%= submit_tag("submit") %>
<% end %>
thanks
