Good afternoon, my friends! I’m skating and I don’t move, the structure of the code is as follows:

insert.php

$.ajax({
   type: 'POST',
   url: 'action.anuncio.php',
   data: dados,
   dataType: 'json',
   success: function(response) {
            location.reload();
      }
});

action.anuncio.php

include_once 'class.anuncio.php';
$anuncio = new Anuncio();
switch ($_POST[]) {
    case 1:
       $anuncio->inserir('informações');
       break;


}

class.anuncio.php 

include_once 'conexao.php';
public Anuncio() {
    function listarAnuncios() {}
    function inserir(){
           /*instruçoes sql para gravação*/
           if($result) {
                $response = array('sucess'=>sucess);
                encode_json($response);
            }
      }


}

The code records and deletes only that it does not update the page, I need to press F5 to update, it seems that the ajax trigger is not receiving the correct answer to give the Reload.

    When you specify dataType: 'json',, the server response must be a response with a valid JSON in the body and a header Content-type: application/json. How’s the php return? did you set the header? a suggestion: if you don’t want any answers back (you do Reload), you don’t have to wait for a JSON. Just send a code 200 in case of success and a code 403 for example in case of error. Another tip, if you allow me: check the tab Network of Developer Tool (Developer Tool) and try to locate this request and what it is returning, if it is expected.

The function Success is not being called. The truth is that many reasons can cause this, you have, for example, put a console.log(dados) so that we can see what is being passed as JSON?

Another tip is to replace the code in action.anuncio.php by removing the SWITCH as follows: 

if(isset($_POST['chave'])) $anuncio->inserir('informações');

Thus preventing errors of Undefined on the PHP side.
