checkValidity() not showing any html5 error notifications when fields are empty and posting with Ajax

I have a form that posts using Ajax, I also want to set an HTML5 required attribute on some input fields, but this stops working as expected with Ajax.
So I did the following:
$("body").on("click",".register-button",function(e){
e.preventDefault();
if($('#registerform')[0].checkValidity()){
registerform = $(".register-form").serialize();
$.ajax({
type:'post',
url:"includes/registreren.php",
data:({registerform: registerform}),
success:function(data){
var content = $( $.parseHTML(data) );
$( "#registerresult" ).empty().append( content );
}
});
}else{
}
});
This way the form is not posted when empty, but I also don't get any notifications that fields are empty like I would get when only using HTML to post.
I also tried logging the validity like so:
$("body").on("click",".register-button",function(e){
e.preventDefault();
$check = $('#registerform')[0].checkValidity();
console.log($check);
registerform = $(".register-form").serialize();
$.ajax({
type:'post',
url:"includes/registreren.php",
data:({registerform: registerform}),
success:function(data){
var content = $( $.parseHTML(data) );
$( "#registerresult" ).empty().append( content );
}
});
});
Which shows false in my console when empty. So the code works, why are the HTML5 notifications not shown? I remember doing something similar in the past and I didn't have to add any custom error messages then, it just worked.
This is my HTML markup:
<form id="registerform" class="register-form" method="post">
<div class="row">
<div class="col-md-6">
<input type="text" name="voornaam" placeholder="Voornaam" required>
</div>

What am I missing?

Disabling and enabling button through jQuery but onclick event not trigerred after button enabled

I have a problem which I dont seem to find a solution for. The problem is this: I have some jQuery which will keep the button disabled until all the form's fields are filled up. When all the fields are filled up the button is being enabled, but the javascript onSubmit event used for the google recaptcha is not being trigerred. Anyone can help in this, please
Code is the one below:
//jquery to disable button until all fields are filled up
$().ready(function() {
// validate signup form on keyup and submit
$("#fbForm").validate({
rules: {
name: {
required: true
},
surname: {
required: true
},
terms: {
required: true
}
},
errorPlacement: function(error, element) {
return true;
},
submitHandler: function() {
}
});
$('#fbForm').change(function() {
if ($("#fbForm").valid()) {
$("#btnSubmit").removeAttr("disabled");
}
});
//recaptcha JS
function onSubmit(token) {
if (screen.width >= 768) {
document.getElementById("fbForm").submit();
}else if (screen.width <= 767){
document.getElementById("fbForm2").submit();
}
}
<form id="fbForm"class="well form-horizontal" action="winesOfDistinction.php?send=true" method="post" data-toggle="validator">

You are missing a } at the last line to close the ready function. Fix that first.

$().ready(function() {
$('#num').validate();
// validate signup form on keyup and submit
$("fbForm").validate({
rules: {
name: {
required: true
},
surname: {
required: true
},
terms: {
required: true
}
},
errorPlacement: function(error, element) {
return true;
},
submitHandler: function() {
}
});
$('#fbForm').change(function() {
if ($("#fbForm").valid()) {
$("#btnSubmit").removeAttr("disabled");
}
});
//recaptcha JS
function onSubmit(token) {
if (screen.width >= 768) {
document.getElementById("fbForm").submit();
}else if (screen.width <= 767){
document.getElementById("fbForm2").submit();
}
}

Okay, Missing jquery validtor and syntax errors were causing the problem. The snippet works fine.You should use visual code as editor and please resolve syntax errors before posting here.

Why is preventDefault not working?

Here is my javascript code. The commented line works:
$("#regForm").submit(function(event) {
// event.preventDefault()
password = $("#inputPassword3")
login = $("#inputEmail3")
user_instance = 0
$.ajax({
url: "{{ url_for('get_users') }}",
method: 'POST'
}).done(function(data) {
data.forEach(function(item) {
if (item.username == login.val() || item.mail == login.val()) {
user_instance = item
}
})
pass_arr = sjcl.hash.sha256.hash(password.val())
hash = sjcl.codec.hex.fromBits(pass_arr)
console.log(hash, user_instance.passwd)
if (hash != user_instance.passwd) {
event.preventDefault()
console.log("+")
password.attr("style", "border:#f00 solid 1px")
password.attr("placeholder", "Wrong password")
}
event.preventDefault() is not working here:
<div id="regForm">
<form class="form-horizontal" method="POST" action="{{ url_for('login') }}">
<div class="form-group">
<label for="inputEmail3" class="col-sm-2 control-label">Email/Login</label>
<div class="col-sm-10">
<input type="imput" class="form-control" id="inputEmail3" placeholder="Email/Login" name="email">
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword3" placeholder="Password" name="password">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<div class="checkbox">
<label>
<input type="checkbox" name="remember_me"> Remember me
</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default" name="sign-in">Sign in</button>
</div>
</div>
</form>
It submits form anyway, even though color of form changing, why is that? When uncommented preventDefault() is working as should be

Try this
$('body').on('submit', 'YOUR-ID' ,function(event) {}

} else {
print "<div class='alert alert-danger'> <button type='button' class='close' data-dismiss='alert'>×</button> We are sorry, but there is a problem. Please Make sure all fields are filled!</div>";
}
?>`

Get rid of the inline onclick() event in your HTML, and let your JavaScript handle the click:
$('#send').click(function(e){
e.preventDefault();
sendContact();
});
preventDefault() stops the click event from acting normally, so your form data is submitted without reloading the page.

Issue with jQuery validate not working against element

I am having an issue using jQuery validate against a form in a current project.
I am sure it is a typo I am missing or something small, but can't sem to figure out why it is occurring.
The error I am getting in the console debugger is: Object doesn't support property or method 'validate'
The bundle configuration file:
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));
bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
"~/Scripts/jquery.validate*"));
bundles.Add(new ScriptBundle("~/bundles/custom").Include(
"~/Scripts/ContactForm.js"));
The code snippets are below:

You have an extra comma.
