drupal 6中的ajax函数不起作用

-1

我需要使用ajax函数过滤region字段im的值，如下面的代码中提到的，但它不起作用。关于功能的AJAX CALL不会进入函数'territory_filter_callback'，无论如何都会知道错误在哪里？drupal 6中的ajax函数不起作用

  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'), 
       ); 



     //FILL THE LIST OF REGIONS 
     $conn = oci_connect('webuser', 'website', '172.16.1.1'); 

     //regions 
     $stid = oci_parse($conn, "SELECt code,descr1 FROM table1.region"); 
    oci_execute($stid); 
    $cidades = array();   while (($row = oci_fetch_array($stid, OCI_ASSOC))) { 
      $cidades[$row['CODE']]= $row['DESCR1']; 
           }  $cidades ['']='Select'; 

     //city 
     $stid1 = oci_parse($conn, "SELECT code,descr1 from table1.city ORDER BY  DESCR1"); oci_execute($stid1); $types = array();  while (($row = oci_fetch_array($stid1, OCI_ASSOC))) {

我真的不能看到任何问号。如果你重写你的“问题”，并且添加一些关于你已经完成并且无法工作的细节，我很乐意删除我的downvote。此外，如果你可以格式化你的代码，以便阅读起来更容易，那将是非常好的。考虑通过您的代码使用相同的缩进。 – sbrattla

的Drupal 6不支持 '#ajax' ...'＃阿贾克斯正在使用Drupal 7 ...在Drupal 6，你可以用 '#ahah'
