QQuery with Ajax?

<?php


    require('includes/prepend.inc.php');
    

    class SampleForm extends QForm
    {

        protected $name;
        protected $btnButton;


        protected function Form_Create() 
        {

            $this->name = new QLabel($this);
            $this->name->Text = 'John';

            $this->btnButton = new QButton($this);
            $this->btnButton->Text = 'Add name';

            $this->btnButton->AddAction(new QClickEvent(), new QAjaxAction('btnButton_Click'));


        } // End of 
        
        

        protected function btnButton_Click ($strFormId, $strControlId, $strParameter) 
        {    
            /*
                $objPerson = new Person();
                $objPerson->FirstName = $this->name->Text;
                $objPerson->Save();
                
                   $objPersonArray1 = Person::QueryArray
                (
                    QQ::Like(QQN::Person()->FirstName, $objPerson->FirstName) //
                );
    
            */
            
        } // End of btnButton_Click


    } // End of SampleForm

    SampleForm::Run('SampleForm');
    
?>

Didn`t find any excamples on how can I extend this SampleForm with QQuery and how can I use QQuery with QAjaxAction. Does anyone know some excamples that may help to get solution?

<?php


    require('includes/prepend.inc.php');
    

    class SampleForm extends QForm
    {

        protected $name;
        protected $btnButton;


        protected function Form_Create() 
        {

            $this->name = new QLabel($this);
            $this->name->Text = 'John';

            $this->btnButton = new QButton($this);
            $this->btnButton->Text = 'Add name';

            $this->btnButton->AddAction(new QClickEvent(), new QAjaxAction('btnButton_Click'));


        } // End of 
        
        

        protected function btnButton_Click ($strFormId, $strControlId, $strParameter) 
        {    

                $objPerson = new Person();
                $objPerson->FirstName = $this->name->Text;
                $objPerson->Save();
                
                   $objPersonArray1 = Person::QueryArray
                (
                    QQ::Like(QQN::Person()->FirstName, $objPerson->FirstName) //
                );
    
            
        } // End of btnButton_Click


    } // End of SampleForm

    SampleForm::Run('SampleForm');
    
?>

Thanks!

Tried again and now it worked... Strange but maybe when I tried earlier, I had some simple problem and got the following error:

http://localhost/

An error occureed during AJAX Responce parsing.

The error responce will appear in a new popup.

And when this type of error panel is displayed and OK is pressed, nothing happens (have tried with 2 different browsers and there was also no sign of pop-up blocking).
