I found hints in the CakePHP 3.x documentation that Helpers can help to "build AJAX functionality" (like here http://book.cakephp.org/3.0/en/views/helpers.html#helpers). But I think there is no further and deeper explanation elsewhere in the docs, how to simplify the usage of AJAX-Calls in CakePHP 3.x.
Does anyone know how Helpers can help me to build AJAX functionality? I would like to extend a Form partially with AJAX-funktionality e.g. to request autosuggest data in an input-formfield.
Are there any concepts beside Helpers to easily implement AJAX-Calls in CakePHP 3.x?
