onChange => remote_function - Not able to get current id

Rails
1

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.
