Dar submit in form with empty field validations

[guilherme]

I have this code that validates a form if you have empty fields or you have it submits the form:

$("#btnAdd").click(function (e) {
e.preventDefault();

var erros = 0;

$("#formAdd input").each(function () {

    $(this).val() == "" ? erros++ : "";

});
$("#formAdd textarea").each(function () {

    $(this).val() == "" ? erros++ : "";

});

if (erros > 0) {

    $("#msg").show().fadeIn(500).delay(1500).fadeOut(600);

} else {
    $(this).submit(function () {
        var form = $(this);
        var dados = new FormData($(this)[0]);
        $("#btnAdd").prop("disabled", true);
        $.ajax({
            url: 'u/add',
            cache: false,
            contentType: false,
            processData: false,
            data: dados,
            type: 'post'
        }).done(function (data) {
            fetchUser();
            alert("Dados Salvos com Sucesso");
            console.log("STATUS : ", data);
            $("#btnAdd").prop("disabled", false);
            $('#modalAddfoto').modal('hide');
            $('.addfoto')[0].reset();
        }).fail(function (jqXHR, textStatus) {
            console.log("Request failed: " + textStatus);
            $("#btnAdd").prop("disabled", false);
        });
        return false;

    });
}

});

it valid normal but is not entering that part of the code:
$(this).submit(function () { ... }

Detail, if I take the validation and do $('#formAdd').submit(function () { ... } works normally.

You can link the submit event directly to the form, and you can pass this as a parameter (already by referencing the Angular).

<form onsubmit="qualquerEvento(this)">
    <button type="submit">Enviar dados</ button>
</ form>
<script>

qualquerEvento(e) { // 'e' agora será o form
    // evitando o comportamento padrão
    e.preventDefault();

    // faz as validações dos campos

    // faz o ajax para o servidor
}

</ script>

It is worth remembering that HTML 5 does not allow certain types of input to be sent with null values, and can further facilitate code writing at validation time.
