Invoke ajax error

Question

I am using, to show that you are loading while sending the client to the web service via php

//Tipo do método
            type: "POST",
            url: "../Processos/AcCadasCliente.php",
            data: $('#formulario').serialize(), 
                beforeSend: function () {
                    // enquanto a função esta sendo processada,
                    // a mensagem "Carregando"
                    $('#enviar').html('.....');
                },
                //Quando terminado a função
                success: function (txt) {
                    //Se deu certo, mostrar mensagem, enviado com sucesso
                    $('#enviar').html('.....');
                },
                //Em caso de erro
                error: function (txt) {
                  $('#enviar').html('Erro');
                }

It happens that even without I have connection with the web service, still, only runs the beforesend and sucess. How to invoke ajax error

Ideally you manage the request status with php, you can use it like this:

if ($tudo_ok)
    {
        header('Content-Type: application/json');
        print json_encode($result);
    }
else
    {
        header('HTTP/1.1 500 Internal Server');
        header('Content-Type: application/json; charset=UTF-8');
        die(json_encode(array('message' => 'ERROR', 'code' => 1337)));
    }
