Form_remote_tag and :with

Rails
1

I am trying to pass the result from a javascript function along with
the result from a text_field with form_remote_tag. This is what I
have so far, but no go:

<% form_remote_tag(:url => {:controller => 'requests', :action =>

‘create’}, :with => “‘data=’+request()”, :update => ‘request_sent’ )
do %>
<%= text_field “request”, “request” %>

<%= submit_tag ‘Send Request’ %>
<% end %>

I was able to get this to work with link_to_remote with the following
code:


<%= link_to_remote ‘Update availability’, :url => {:action =>
“array”}, :with => “‘data=’+test()”, :update => ‘testing’ %>

where test() is the javascript function. This allows me to access the
result of the test function in params[:data]. It seems that I should
be able to do the same with form_remote_tag, but I have been
unsuccessful. Maybe a syntax mistake? Maybe not possible?

result() is the name of a javascript function that I have defined
within a script in the head element. calling it in :with sets this
result to data, which can then be accessed with params[:data] in the
action create.

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” %>

<%= 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.

Oh i forgot to include the <% end %> code. I have that and it still
does not work.

can anyone help with this syntax? I figure anything that works for
link_to_remote has got to work for form_remote_tag. Does anyone know
if its possible to use the :with to pass parameters using
form_remote_tag? This is what I have so far, but the params[:time]
passed in :with is still nil and it works with link_to_remote.

<%= form_remote_tag :url => {:controller => 'requests', :action

=>‘create’, :month => @month,
:day_number => @day_number, :day_name => @day_name, :id =>
@id},
:with => “‘time=’+timeReturn()”, :update => ‘request_sent’ %>
<%= text_field “request”, “request” %>

<%= submit_tag(‘Send Request’) %>
<% end -%>

All the other params, i.e. month and day_number are passed, so i know
the general syntax is working, its just the :with that is giving me a
problem.

turns out you need to use submit_to_remote:

<% form_tag :url => {:controller => ‘foo’, :action =>‘bar’, :month =>
@month,
:day_number => @day_number, :day_name => @day_name, :id => @id} do
%>
<%= text_field “request”, “request” %>

<%= submit_to_remote(‘submit’, ‘Send Request’, :url =>
{:controller => ‘foo’, :action =>‘bar’, :month => @month,
:day_number => @day_number, :day_name => @day_name, :id =>
@id},
:with => “‘time=’+timeReturn()”, :update =>
‘request_sent’, :confirm => “sure?”) %>
<% end %>
