wordpress Ajax call to php function doesn't work - php

Question

I've tried a bunch of different things but I just cannot get AJAX with Wordpress to work. I clearly don't get something but I do not know what it is. Always get a result on admin-ajax.php 0
public function enqueue_scripts() {
wp_enqueue_script( $this->plugin_name, plugin_dir_url( __FILE__ ) . 'js/jquery-3.3.1-public.js', array( 'jquery' ), "3.3.1", false );
wp_enqueue_script( 'ajax-script', plugin_dir_url( __FILE__ ). 'js/wp-public.js', __FILE__, array() , $this->version, true);
wp_localize_script( 'ajax-script', 'ajax_object',
array(
'ajax_url' => admin_url( 'admin-ajax.php')
)
);
}
wp-public.js
$(document).ready(function()
{
$(".like-btn, .dislike-btn").click(function()
{
var id = this.id; // Getting Button id
var split_id = id.split("_");
var text = split_id[0];
var postid = split_id[1]; // postid
// Finding click type
var type = 0;
if(text == "like-btn") {
type = 1;
}else {
type = 0;
}
// AJAX Request
$.ajax(
{
url: ajax_object.ajax_url,
type: 'post',
data: {
'action': 'my_action',
postid: postid,
type: type
},
dataType: 'json',
success: function(data) {
$("#likes_"+postid).text(data.likes); // setting likes
$("#unlikes_"+postid).text(data.unlikes); // setting unlikes
$("#msg_"+postid).text(data.msg); // setting messages
if (data.likes || data.unlikes > "") {
if(type == 1) {
$("#like-btn_"+postid).css("color", "#0757fe");
$("#dislike-btn_"+postid).css("color", "#8e8e8e");
}
if(type == 0) {
$("#dislike-btn_"+postid).css("color", "#f1476e");
$("#like-btn_"+postid).css("color", "#8e8e8e");
}
}
}
}
);
}
);
}
);
included class
class Wp_Ahb_Content {
public function __construct( ) {
add_action('wp_ajax_my_action','my_action');
add_action('wp_ajax_nopriv_my_action','my_action');
}
function my_action() {
global $wpdb;
$whatever = $_POST['postid'] ;
echo "postid".$whatever;
}

Answer 1

My_action function is not running
JUST Delete add_action from __construct () and add them to loader
add_action ('wp_ajax_my_action', 'my_action');
add_action ('wp_ajax_nopriv_my_action', 'my_action');
And I became as follows: ON private function define_public_hooks()
$this-> loader-> add_action ("wp_ajax_my_action", $ plugin_public, "ajax_object");
 
$this-> loader-> add_action ("wp_ajax_nopriv_my_action", $ plugin_public, "ajax_object");
It became operational
I just wanted to clarify, because I found a lot of questions
