If you want to use form validator in ajax side use following code :

Myform.php

class Application_Form_Myform extends Zend_Form
{ 
    # init function & ... 
    public function generateform($nohash = false)
    { 
        # Some elements
        if(!$nohash)
        {
           $temp_csrf = new Zend_Session_Namespace('temp_csrf'); 
           $my_hash = new Zend_Form_Element_Hash ( 'my_hash' );
           $this->addElement ( $my_hash , 'my_hash');  
           $temp_csrf->hash = $my_hash->getHash();
        }
        # Some other elements
    }
}

AjaxController.php

class AjaxController extends Zend_Controller_Action
{ 
    // init ... 
    public function validateAction()
    { 
         # ... 
         $temp_csrf = new Zend_Session_Namespace('temp_csrf');
         if($temp_csrf->hash == $params['received_hash_from_client'])
         {
             $Myform     = new Application_Form_Myform(); 
             $Myform->generateform(true);
             if($AF_Bill->isValid($params))
             {
                 # Form data is valid
             }else{
                 # Form invalid
             }
         }else{
             # Received hash from client is not valid
         }
         # ... 
    }
}
