I would like to say that I searched the forum and found some similar questions, but no answer solved my problem. Follow my own doubt:

Doubt:

I am trying to delete a notification by ajax, but the error is occurring. The variables id_project and n_notification are as Undefined. How to solve this problem?

Error:

Projectocontroller.php: (method removeNotification)

//Este método remove a Notificação
        public function removeNotificacao(Request $request)

            $nnotificacao = $request->nnotificacao;
            if (!$notificacao)
            return response()
                        ->json(['error' => 'not_found'], 404);

            $response =  $notificacao->deletarNotificacao($notificacao);

Try to use:

var n_notificacao = $('#numNotificacao').html();

Thank you, I’ll test.

If the document is xhtml, it should be used $('#numNotificacao'). text();

First of all, thank you for the return. I did the tests in the ajax file and the same is receiving the values of the variables idProjNotificacao' and numNotificacao. The problem occurs in the Projectocontroller.php controller when deleting the data. When debugging the network tab the following error appeared when I used the $Response = $notification->delete() command: message: A non-numeric value encountered Exception: Errorexception file: c: xampp htdocs Union app Http Controllers Admin Projectntroller.php

I didn’t see in the code how you’re setting the attribute data button #btnExcluirNotificacao.

But you can try it like this and see if it works:

//Ajax para remover uma notificação, e atualizar a página após a ação
$('.removeNotificacao').click(function () {

    var data_id = $('#btnExcluirNotificacao').data('id');
    var n_notificacao = $('#btnExcluirNotificacao').data('nnotificacao');

If it doesn’t work, try:

var data_id = $('#btnExcluirNotificacao').attr('data-id');
var n_notificacao = $('#btnExcluirNotificacao').attr('data-nnotificacao');

Leo Klaj, thank you for your reply. I did the tests as recommended in addition I tested the following codes: var data_id = $('#idProjNotificacao'). val(); var n_notification = $('#numNotification'). val(); and the following form var data_id = $('#idProjNotification'). html(); var n_notification = $('#numNotification'). html(); But the error persists. The error is occurring when the id and nnotification variables are passed to the controller (Projectocontroller.php).

Then it seems that the btnExcluirNotification button does not have the date attributes set. Try giving console.log to see if the attributes are there anyway.
