Rails - Apr 2006 - selected value

I would like to pass the value selected in a select statement back so 
that I can use it in the controller, through using a remote_function 
call, and I cannot figure out what I am doing wrong:

view rhtml:
<select id="widgets_id" name="widgets[id]"
onchange="<%=
remote_function( :update => "parts", :url=> { :action =>
:loadParts } )
%>">
<%= options_from_collection_for_select @widgets, ''id'',
''name'' %>
</select>

Select is built fine.  I cannot find documented anywhere, where I can 
pass back the current value of the select (ie, something like "id => 
...)

Any help greatly appreciated.  TIA

Have a look at the remote_function() :with option.

Cheers,

This should do what you want. (I split up the remote_function thing to
make it easier to read in the email.)

<% func = remote_function(:update => "parts", :url =>
{:action =>
:loadParts}, :with => "''id='' + escape(value)"
-%>

<select id="widgets_id" name="widgets[id]"
onchange="<%=func%>">
  <%= options_from_collection_for_select @widgets, ''id'',
''name'' %>
</select>
