So this returns the correct value in params[:data]:
<%= link_to_remote 'Send Request', :url => {:controller =>
"requests", :action => "create",
:date => @date, :weekday => @weekday, :id => @id}, :with =>
"'data='+newFunction()",
:update => 'request_sent' %>
but this returns nil:
<% form_remote_tag(:url => {:controller => 'requests', :action
=>'create'},
:with => "'data='+newFunction()", :update => 'request_sent')
do %>
<%= text_field "request", "request" %><br/>
<%= submit_tag 'Send Request' %>
am I using :with within the form_remote_tag helper correctly? Are you
able to use it with form_remote_tag? Thanks.
