Try searching the web for keywords remote_function and select_tag
For example, this is close to what you want.
<%= select_tag( :sort_by, options_for_select([["Sort by:",0],["Name",'name'],["Price",'price'], ["Date Listed",'id']],0), :onchange => remote_function( :with => "'sort_by='+$(\"sort_by\").value", :loading => "false;", :url => { :controller => 'products', :action => :change_order } ) ) %>
I realize this is largely a question of taste, but wouldn't Proper Rails Style prefer to invoke the remote function via the observe_field helper rather than the onchange attribute value? I ask in all sincerity, not having a great grasp yet of Proper Rails Style.
