Subject: select box question

Hi,

Yet another newbie here... I'm writing an appliction in Rails, and I've 
Ajaxified my select boxes so they update dynamically.  I used the 
"observe_field" method to monitor changes to my select box.  I find that 
it's kind of erratic... it updates constantly and makes the selection 
for me, based on where my mouse happens to be hovering when it does its 
observation.  Not very user friendly.  I'd much rather the onChange 
event, but I'm not sure exactly how to write the syntax for using the event.

Here's my code as it is now:

  <select id="product[proddesc_pk]" name="product[proddesc_pk]">
    <%= options_from_collection_for_select(
        Product.find_all, "proddesc_pk", "prod_name"
        ) %>
  </select></p>
  <%= observe_field("product[proddesc_pk]",
      :frequency =>0.25,
      :update => "component_id_list",
      :url => { :action => :fill_component_box},
      :with => "'id='+value")
  %>

How would I go about changing that code so that it updates based on an 
onChange event, rather than the observation?

Any help would be greatly appreciated!

Thanks,
~ Shanan
