auto complete text field triggering another method?

Hi Ian,

Maybe you could add an :after_update_element to your
text_field_with_auto_complete, e.g.

<%= text_field_with_auto_complete :model, :method,
{}, :after_update_element => 'getAddresses' %>

Then define a Javascript function to your head which calls
Ajax.Updater like:

function getAddresses(text, li) {
   new Ajax.Updater('mydiv', '/foo/bar/' + text, {asynchronous:true});
}

Where bar is a new action in your controller which returns your
addresses into a div named mydiv.

Hope that helps. You can find more on the rails and scriptaculous
wikis although they both seem to be down at the moment(!)
