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>

var nameInput = document.getElementById('inputName').value;
localStorage.setItem('text', dataInput);

to redirect the same page after form submit

I have a form in my webpage Index.html. When I submit my form it redirects to the action page.
I want the page to redirect to itself (index.html) after completing the action.
<div class="container">
<div class="row marginbot-80">
<div class="col-md-8 col-md-offset-2">
<form id="contact-form" method="post" action="mailfunc.php" class="wow bounceInUp" data-wow-offset="10" data-wow-delay="0.2s">
<div class="row marginbot-20">
<div class="col-md-6 xs-marginbot-20">
<input type="text" class="form-control input-lg" id="name" placeholder="Enter name" required="required" />
</div>
<div class="col-md-6">
<input type="email" class="form-control input-lg" id="email" placeholder="Enter email" required="required" />
</div>
</div>
<div class="row">
<div class="col-md-12">
<div class="form-group">
<input type="text" class="form-control input-lg" id="subject" placeholder="Subject" required="required" />
</div>
<div class="form-group">
<textarea name="message" id="message" class="form-control" rows="4" cols="25" required="required" placeholder="Message"></textarea>
</div>
<button "style=width:40 height:40" class="btn btn-skin" type="submit" id="btnContactUs">Send Message</button>
</div>
</div>
</form>
</div>
</div>
</div>

You could redirect after the script in mailfunc.php to your index.html like this:
header("Location: index.html");
exit();

Currently your submit will open a POST request to mailfunc.php where your form data (most probably) will be processed.
You can quite easily forward from mailfunc.php to index.html using some Javascript code like:
window.location.href = 'index.html';

Try this.
$referer = $_SERVER['HTTP_REFERER'];
header("Location: $referer");
This helps you to redirect to the same page where you are submitting the form

Error in submitting form using ajax

For some reason, the form is not getting submitted. I have used ajax form to save the form details in my database.
Here is the site link:
http://www.famproperties.com/mudon/Abu-Dhabi/villas.html
Here is the script code.
<script>
$(document).ready(function() {
$("#submit-form-button").click(function() { submitForm(); });
});
function submitForm() {
if ( $("#NAME").val() == '' ||
$("#EMAIL").val() == '' ||
$("#MOBILE").val() == '' ||
$("#NOTE").val() == '' )
{ alert ("All field are required");}
else {
$.ajax({
type: "POST",
url: "http://famproperties.com/real_estate/property/contact/lead/",
data: {
NAME: $("#NAME").val(),
EMAIL: $("#EMAIL").val(),
MOBILE: $("#MOBILE").val(),
NOTE: $("#NOTE").val(),
SOURCE: 'MSB.COM'
},
success: function() {
alert("Thanks, Our specialist will contact you soon.");
},
dataType: 'html'
});
$("#NAME").val('');
$("#EMAIL").val('');
$("#MOBILE").val('');
$("#NOTE").val('');
}};
</script>
Here is the form code.

<!--NEW FORM-->

Seeing the page on http://www.famproperties.com/mudon/Abu-Dhabi/villas.html you are not even loading jquery check the console and youll see this error:
Uncaught ReferenceError: $ is not defined
Thats why ajax is not working
Edit: Sorry, checking your code again i saw you are loading jQuery but you are trying to use jQuery before loading it. So, try moving the jquery script tag to the header or move your js below the jQuery script tag.

How to empty ajax loaded form?

How can we empty a ajax loaded form using pure JavaScript or jQuery.
I have tried document.forms[0].reset(); and $('#new-staff-form')[0].reset(); both didn't work it returns undefined.
Update
<div class="box col-md-12 new-staff">
<form id="new-staff-form" method="post">
<div class="row">
<div class="col-md-6">
<label for="f_name">First Name</label>
<input type="text" name="f_name" placeholder="First name"/>
</div>
<div class="col-md-6">
<label for="l_name">Last Name</label>
<input type="text" name="l_name" placeholder="Last name"/>
</div>
</div>
<div class="row">
<div class="col-md-6">
<label for="user_name">User name</label>
<input id="user_name" type="text" name="user_name" placeholder="User name"/>
</div>
<div class="col-md-6">
<button id="user-avail" class="btn btn-primary">Check available</button>
</div>
</div>
<div class="row">
<div class="col-md-12">
<button class="btn btn-primary pull-left">Save</button>
</div>
</div>
</form>
</div>
Javascript:
$('#new-item').click(function(){ // works fine until I load new html form using ajax with same ids and class
$('#new-staff-form')[0].reset();
$('.new-staff').slideToggle(); // show new form
});
$('.edit-item').click(function(){ // ajax call this loads everything correctly
var id = $(this).data('staf_id'); //item to delete
$.ajax({
url:url_view_staff+id,
type:'get'
}).done(function(data){
edit_item_id = id;
$('.new-staff').html(data).slideDown();
}).fail(function(data){
$('#errors').html(data.responseText);
$('.valid-error').slideDown();
});
});

JavaScript:
document.getElementById("myForm").reset();
Jquery :
$('#form_id')[0].reset();
Make sure your form id is valid.

FIDDLE
$('#configreset').click(function(){
$('#configform')[0].reset();
});
