How to display a message after deleting a record using php?

Question

I have a page with a list of data and for each record I have the option to delete. When I click the delete button, before performing the action it checks in a controller file which action was requested to only then do the execution of the deletion code.

The stock flow goes something like this:

Click on the Button => Checking in the Controller => Executes Action

I tried to print a message on screen after code execution, but the message is displayed on the controller page. Which is not certain because this page should not display anything, being only a bridge between the request and the desired action.

To request the deletion I am using the post method. Would it be possible to make the confirmation message appear on the page where the listing exists? If possible, how could it be done?

Yes, you can do this using AJAX. The code looks something like this:

jQuery.ajax({
  type: "POST",
  url: URL-DA-SUA-REQUISICAO,
  data: DADOS-DA-SUA-REQUISICAO,
  success: function sucesso(dados) {
    document.write('Concluido')
  },
  error: function erro(error) {
    document.write('Ops, um erro ocorreu')
    console.error(error)
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Remember, in this case, the field function error will only be called if an error occurs in the request or when the returned HTTP status is an error status.
