Hi,
I want to make a selection list, which I call a dropdown, which, when a user makes his or her selection, will do an ajax call, and update a partial. Without hitting a button -- the ajax request will fire off upon the selection.
I'd appreciate a hint -- can't figure out where to start.

Charlie,
The Agile Book is always a good place to start looking for things Rails. In your case, page 523-526 in the 2nd Edition has some good stuff that can get you started on what you want.

Is a form observer the way to go with this? I was thinking of just doing an onchange, so that when any element is selected, it fires off an ajax request.
Either way would work. I prefer to write less javascript and let the observer deal w/ the ajax request, but they will both do basically the same thing one is a little more rails, the other a little more javascript.

I use observers for this all the time doing exactly what you want. I use it in my pagination footer. I give the user a list of available pages, and if a new page is chosen, the observer fires off an ajax request which then uses rjs to update the page results.

By way of an example:
The default for observe field is on change so the call to remote occurs whenever a selection is made:
<%= select 'order', 'ship_method', ['1st Class Standard', '1st Class Recorded','Next Day Courier', 'Special Delivery' ]%>
........
<%= observe_field :order_ship_method, :url=>url_for(:action=>:edit_batch_field, :controller=>'order', :id=>@order.id), :with=>"ship_method"
%>

Very good. Thanks to all. This is one of those things where I didn't know what to look for in the first place. Got it working now.
