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. On Aug 18, 12:16 am, "K.

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. charlie caroff wrote:> Is a form observer the way to go with this?

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. K.

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.
