Best practices to add AJAX to my admin component

[GhiaMar]

Hi! reading and wandering around docs I found that I can support AJAX requests in my administrator component in a controller task or in a JsonView and even found that some components have an AjaxController like com_menus (which I don't know what exactly does that AjaxController thing).

¿Which is the right place form my admin component to support AJAX requests? My use case is:

The user tries to send a message to a group of recipients (like the admin user component mail function, but not using email) and I need to show the sending progress to the user . In the sending process, my component need to send the messages in chunks of 100 recipients each time, so for that, I need to send an AJAX request for each chunk, until all recipients chunks are done sending.

But where?

• In my component ...\Administrator\Controller\SendController send() method?
• Or to my component  ...\Administrator\View\Send\JsonView display($tpl = null) method?
• Or somehow hit some method in my component ...\Administrator\Controller\AjaxController ?
  

I want to use AJAX because after the sending process starts, I want to be able to tell the user how the sending is doing and also avoid PHP max execution time limits.

Thanks in advise!

Found my answer diggin in the ApplicationController->sendtestmail() of the com_config component.

The sendtestmail member function uses JsonResponse along with the JS class JoomlaFieldSendTestMail in media/system/js/fields/joomla-field-send-test-mail.js

I think if this so common test email utility is coded this way in the Joomla core, it should be the best practice.

Thanks anyway
