Drupal_add_js just makes the JavaScript accessible to your application. You'll still need to do something with it. It looks like you're creating a form, so can I assume you're using the Forms API? Maybe you could use the #attributes element to add your onchange/onblur/whatever to your form field.

That said, I am fairly new to Forms API, so maybe there's a better method. This is just an idea.

So you start with a form and within the form you use drupal_add_js to
embed the ajax within the form. Correct?
If I have a custom module that has a hook function and within the hook
function can I just use drupal_add_js to do an ajax call?
Sorry for the stupid questions I am new to Drupal and php.
Thanks,
John
