Rails - May 2009 - onChange => remote_function - Not able to get current id

Hi,

Below is the code I am using to display drop down. This drop down is for
displaying categories.

<% form_for :category do |form| %>
  <%= form.collection_select(:id,@categories, :id,
    :category_name, {},
    {:onChange =>
remote_function(:url=>{:action=>''say_hello'',
        :with => "''id=''+value"},
        :update=>''mydiv'')}
       )  %>
<% end %>

I want to get the ''current category id'' during onchange. Using
:with =>
"''id=''+value" I am not able to get it.


Plaese anyone suggest

Maybe "with" section should look like with =>
''id=''+value? I think in
your variant you assign to id a string value ''value''.

Bob

For a start, you have :with as part of the :url hash... it should be  
on the same level as :update.
