Augustin, this may not be the easiest place to find it, but I made a page here already for 6.x/forms AJAX: http://drupal.org/node/150859 -Peter

Hello,
See my message to the documentation list about where to document everything ajax, ahax, js, and jquery. http://drupal.org/node/121997
Right now, I am trying hard to understand book.js and ... I just don't get it.
In book.js, there is an ajax call:
$.ajax({ url: Drupal.settings.book.formCallback +'/'+ $('#'+ Drupal.settings.book.formId +' input[name=form_build_id]').val() +'/'+ $('#edit-book-bid').val(), dataType: 'json', success: function(data) { // Insert the new select, and remove the progress bar. $('#edit-book-plid-wrapper').after(data['book']).remove(); }
in book_menu(), there is a menu callback, which I guess is the callback used by the js above:
$items['book/js/form'] = array( 'page callback' => 'book_form_update', 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, 'file' => 'book.pages.inc', );
But everything javascript and ajax being completely undocumented, I am having a hard time to connect the two together, even by looking at drupal.js, looking at the big documentation block above drupal_add_js() (in common.inc), which I don't understand at all (I told you it was too early to change my handle!!)
How does this...
$.ajax({ url: Drupal.settings.book.formCallback +'/'+ $('#'+ Drupal.settings.book.formId +' input[name=form_build_id]').val()+'/'+ $('#edit-book-bid').val(),
...lead to the book/js/form callback???
I sense it is connected to Drupal.attachBehaviors (in drupal.js) and Drupal.behaviors.bookSelect (book.js), but I don't know how.
As I always do, if you tell me both the answer and where to document this, I'll have a go at starting a documentation.
Thanks and blessings,
Augustin.
