title: How to dynamically reconfigure Drupal's jQuery-based autocomplete at runtime?
body: <p><a href="http://drupal.org/" rel="noreferrer">Drupal</a> has a very well-architected, <a href="http://jquery.com/" rel="noreferrer">jQuery</a>-based <a href="http://cvs.drupal.org/viewvc.py/drupal/drupal/misc/autocomplete.js?revision=1.23&amp;view=markup&amp;pathrev=DRUPAL-6" rel="noreferrer">autocomplete.js</a>. Usually, you don't have to bother with it, since it's configuration and execution is handled by the Drupal form API.</p>
  
  <p>Now, I need a way to reconfigure it at runtime (with JavaScript, that is). I have a standard drop down select box with a text field next to it, and depending what option is selected in the select box, I need to call different URLs for autocompletion, and for one of the options, autocompletion should be disabled entirely. Is it possible to reconfigure the existing autocomplete instance, or will I have to somehow destroy and recreate?</p>
