ajax fonction dans drupal 6 ne fonctionne pas

Question

Je dois filtrer le champ de territoire sur la valeur du champ de région im en utilisant la fonction ajax comme il est mentionné dans le code ci-dessous, mais cela ne fonctionne pas. AJAX CALL sur la fonction n'entrera pas dans la fonction 'territory_filter_callback' de toute façon sache où est l'erreur?

  function form_search_menu() { 

      $items['form/search'] = array(
      'title' => t('Search'), 
      'page callback' => 'drupal_get_form', 
      'page arguments' => array('_search'), 
      'access callback' => TRUE, 
      'description' => t('search'), 
       ); 
      return $items; 
       } 

     function _search(&$form_state) { 
     drupal_add_js(drupal_get_path('module', 'form_search') .'/script.js'); 
      $form['description'] = array(
      '#type' => 'item', 
      '#title' => t('Search page'),

Answer 1

6 prennent pas en charge drupal '#ajax' ... '# ajax' travaille avec 7 ... à l'aide de Drupal 6, vous pouvez drupal utiliser '#ahah'
