Contact form with PHP Mailer, which refreshes whole page when clicking Send

I did contact form with PHP Mailer, JavaScript and Ajax call
Everything works fine, expect javascript after clicking on button. (I even recieve an email sucessfully)
My html code:
<form id="contact-form" class="contact">
<div class="col-md-6">
<input type="text" name="name" id="fullname" placeholder="Fullname">
</div>
<div class="col-md-6">
<input type="email" name="email" id="email" placeholder="Email adress">
</div>
<div class="col-md-12">
<textarea id="message" name="message" placeholder="Message"></textarea>
</div>
<div class="col-md-12">
<button id="gumb" type="button" class="btnc" onclick="validateContact();">Send</button>
</div>
</form>
</div>
<div class="col-md-12">
<div id="response_brought"></div><!-- This will display the response from the server -->
<p> </p>
</div>
JavaSript code (This works fine, but after i press button, I RECIEVE EMAIL but my last response stays the same.. it doesn't change. It display response from fullname=="" ('Please enter your fullname in the required field to proceed. Thanks.').. So I guess there is an error inside Ajax call
function validateContact() {
"use strict";
var valid = true;
var reg = /^([A-Za-z0-9_\-\.])+\#([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
var formData = {
fullname: $("#fullname").val(),
email: $("#email").val(),
message: $("#message").val(),
};
var fullname = $("#fullname").val();
var emailreg = $("#email").val();
var message = $("#message").val();
//dataString = {'fullname': fullname, 'email': email, 'message': message, 'submitted': '1'};
if (fullname === "") { //Validation against empty field for fullname
$("#response_brought").html('<br clear="all"><div class="form_info" align="left">Please enter your fullname in the required field to proceed. Thanks.</div>');
$("#fullname").focus();
valid = false;
} else if (emailreg === "") { //Validation against empty field for email address
$("#response_brought").html('<br clear="all"><div class="form_info" align="left">Please enter your email address in the required email field to proceed. Thanks.</div>');
$("#email").focus();
valid = false;
} else if (reg.test(emailreg) === false) { //Validation for working email address
$("#response_brought").html('<br clear="all"><div class="form_info" align="left">Sorry, your email address is invalid. Please enter a valid email address to proceed. Thanks.</div>');
$("#email").focus();
valid = false;
} else if (message === "") { //Validation against empty field for email message
$("#response_brought").html('<br clear="all"><div class="form_info" align="left">Please enter your message in the required message field to proceed. Thanks.</div>');
$("#message").focus();
valid = false;
}
valid = true;
$.ajax({
type: "POST",
url: "sendemail.php",
data: formData,
success:function(data){
var response_brought = response.indexOf('Congrats');
$(".contact-form").slideUp(500);
$("#response_brought").html(response);
setTimeout(function () {
$("#response_brought").html('');
}, 10000);
},
error:function (){}
});
}

$mail->send();
$success = "Message sent successfully";
} catch (Exception $e) {
$error = "Sorry message could not send, try again";

PHP/Javascript validation works partially

I have Javascript/Ajax and PHP validation for my form. It's displays the errors if the form filled incorrectly, but it won't work and let me submit the form even if there is no errors. Basically ,when I click the submit button it stays at the same page and won't do anything.
In console I got the next error on submit: Failed to load file:///C:/Users/ilona/Desktop/BootstrapLandinPage/send.php: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https. jquery-2.2.4.min.js:4. I run my project on XAMPP.

You are opening the file directly unless you configured it in Apache. The file seems to not have connection to your web server XAMPP.
You need to do following:
Copy BootstrapLandinPage directory to c:/xampp/htdocs
Add virtual host to XAMPP
Open the file C:\xampp\apache\conf\extra\httpd-vhosts.conf and add this snippet, adapted to your environment.
<VirtualHost 127.0.0.2:80>
ServerName playground.localhost
ServerAlias playground.localhost
DocumentRoot c:/xampp/htdocs/your_website
<Directory "c:/xampp/htdocs/your_website/">
Options +Indexes +Includes +FollowSymLinks +MultiViews
AllowOverride All
Require local
</Directory>
</VirtualHost>
Restart Apache in control panel of XAMPP (click XAMPP icon in bottem right in Windows)
Open browser and enter IP address 127.0.0.2 (the one you assign in virtual host)
Now you site should appear with PHP capabilities.
UPDATE
After the latest comment i add here a way to send emails via localhost.
Use a PHP library to send mails from email address of your domain provider:
Download PHPMailer
Copy the ZIP contents into a separate directory in BootstrapLandinPage. For example: lib/PHPMailer
Add these lines to the top of you process.php
require 'path/to/PHPMailer/src/Exception.php';
require 'path/to/PHPMailer/src/PHPMailer.php';
require 'path/to/PHPMailer/src/SMTP.php';
Add the example snippet on the documentation page where you downloaded the package and ajust to your needs.
Alternatively for local mailing:
Download hmailserver
Install it following their tutorial
Navigate to C:\Windows\System32\drivers\etc\hosts file and open it as administrator
Add following line:
127.0.0.1 localhost localhost.com
Add user example#localhost.com to your hmailserver
Configure mail account in your mailing app using:
Username: example#localhost.com
Password: your_password
IMAP/SMTP Server: localhost
UPDATE 2
This would be your PHP code using PHPMailer:
require 'path/to/PHPMailer/src/Exception.php';
require 'path/to/PHPMailer/src/PHPMailer.php';
require 'path/to/PHPMailer/src/SMTP.php';
$error_msg = array();
$success_msg = array();
$data = '';
// prevent warnings or errors from displaying, else you won't get proper json result

} else {
$name = test_input($_POST["name"]);
// check if name only contains letters and whitespace
if (!preg_match("/^[a-zA-Zא-ת ]*$/",$name)) {
$error_msg['name'] = "Only letters and white space allowed";
}
}
if (empty($_POST["email"])) {
$error_msg['email'] = "Email is required";
} else {
$email = test_input($_POST["email"]);
// check if e-mail address is well-formed

$error_msg['phone'] = "Invalid phone number";
}

Detect PHP Mailer error and print the message in the website using jquery

I am using PhpMailer to send emails. Inside my own script I want to parse some javascript inside the below if statement. Note that I have html enabled.
When the email is not sent I want to parse some javascript inside the .done function that the email is not sent. eg complete.html("Message Not Sent!"); When the email is sent, I want to show that the email is sent. How can I do that and where is better to do that, inside php file or inside the javascript?
var form = $('#contact');
form.submit(function(event) {
event.preventDefault();
var complete = $('#formAppend');
var $form = $(this);
var name = $("#fname").val();
var email = $("#email").val();
var Message = $("#msg").val();
var countryoption = $("#country").val();
$.ajax({
type: 'POST',
url: '../sendemail.php',
data: {
Name: name,
Email: email,
message: Message,
Country: countryoption
},
beforeSend: function() {
complete.html('Message is Sending...').fadeIn();
}
})
.done(function(data) {
//This should change depending on the php if statement at the bottom.
complete.html("Message Sent");
});
}); //end contact form
<form id="contact" method="post" action="#ss">
<div id="formAppend"></div>
<input type="text" id="fname" name="firstname" placeholder="Το όνομα σας.." required>
<input type="email" id="email" name="email" placeholder="Το email σας.." required>
<select id="country" required>

if(empty($_POST['Name'])){

} else {//Message sent!
echo "Well done $from_name, your message has been sent!\nWe will reply to the following email: $from"
. "<br>Your Message: $body";
}
} //end function smtpmailer
?>

Change you PHP and JS code like this........
require 'PHPMailer-master/PHPMailerAutoload.php';
if (empty($_POST['Email'])) {
$_POST['Email'] = "";
}
if (empty($_POST['Name'])) {
$_POST['Name'] = "";
}
if (empty($_POST['message'])) {
$_POST['message'] = "";
}
if (isset($_POST["message"]) && !empty($_POST["message"])) {
$mymail = smtpmailer("webdominar1#gmail.com", $_POST['Email'], $_POST['Name'], $_POST['message']);
} else {
header('Location: http://webdominar.xyz');
exit();
}
function smtpmailer($to, $from, $from_name, $body) {
$mail = new PHPMailer;
$mail->isSMTP();
$mail->Debugoutput = 'html';
$mail->Host = 'smtp.gmail.com';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = '';
$mail->Password = '';
$mail->SetFrom($from, $from_name);
$mail->Subject = "Εμβολιασμός Δέντρων ~ Φόρμα Επικοινωνίας ~ $body ";
$mail->CharSet = 'UTF-8';
$mail->isHTML(true); // Set email format to HTML
$Country = $_POST["Country"];
$mail->Body = "BLABLA "; //end email body
$mail->AddAddress($to);
//send the message, check for errors
if (!$mail->send()) { //Message not sent
//echo "Mailer Error: " . $mail->ErrorInfo;
$responce = array(
'message' => $mail->ErrorInfo,
'success' => FALSE,
);
echo json_encode($responce);
} else {//Message sent!
$msg = "Well done $from_name, your message has been sent!\nWe will reply to the following email: $from"
. "<br>Your Message: $body";
$responce = array(
'message' => $msg,
'success' => TRUE,
);
echo json_encode($responce);
}
}
Change your JS code like this
var form = $('#contact');
form.submit(function(event) {
event.preventDefault();
var complete = $('#formAppend');
var $form = $(this);
var name = $("#fname").val();
var email = $("#email").val();
var Message = $("#msg").val();
var countryoption = $("#country").val();
$.ajax({
type: 'POST',
url: '../sendemail.php',
data: {
Name: name,
Email: email,
message: Message,
Country: countryoption
},
beforeSend: function() {
complete.html('Message is Sending...').fadeIn();
}
})
.done(function(data) {
var response=JSON.parse(data);
if(response.success == true) {
//return true
complete.html("Message Sent");
// if you want show Response message which get form sendemail.php
complete.html(data.message);
} else {
//return false
complete.html("Message Not Sent!");
// if you want show Response message which get form sendemail.php
complete.html(data.message)
}
//This should change depending on the php if statement at the bottom.
});
}); //end contact form

Change the end of your PHP to:
header("Content-type:application/json");
$message = "Well done ".$from_name.", your message has been sent!<br/>We will reply to the following email:".$from."<br>Your Message: ".$body;
if (!$mail->send()) {
echo '{"error":"'.$mail->ErrorInfo.'"}';
} else {
echo '{"success":"'.json_encode($message).'"}';
}
Then you can do this in the .done:
.done(function(data) {
if (data.error) {
complete.html(data.error).addClass("error");
}
else
complete.html(JSON.parse(data.success));
}
});

Check the security of form.

My account was suspended because of SPAM several times and my host provider told me to check my website security. May be my forms are not secured enough. Do you think that this form can be used to send spam?
Here is my code:
<script type="text/javascript">
$(document).ready(function () {
$('#form').ajaxForm({
beforeSubmit: validate
});
function validate(formData, jqForm, options) {
var name = $('input[name=name]').fieldValue();
var email = $('input[name=email]').fieldValue();
var company = $('input[name=company]').fieldValue();
var location = $('input[name=location]').fieldValue();
var phone = $('input[name=phone]').fieldValue();
var message = $('textarea[name=message]').fieldValue();
if (!name[0]) {
alert('Please enter your name');
return false;
}
if (!company[0]) {
alert('Please enter the name of your organization');
return false;
}
if (!email[0]) {
alert('Please enter your e-mail address');
return false;

Many thanks!

Your form would actually be not safe against bots, because you dont got any captcha or something.
2 Options for you:
Captcha
Captcha -> you got something to fill in -> you probably know this!:)
https://www.google.com/recaptcha
Honeypot
Honeypot means, you are adding hidden fields in your form. And if those hidden fields have changed - you know that a BOT has entered content in your form. Aswell, this is better than Captchas, because your User doesnt has to fill in a Captcha
I would prefer Honeypot, because I don't like forms, where i have to fill in a Captcha once or even twice, when I failed or the captcha wasnt readable.
http://haacked.com/archive/2007/09/11/honeypot-captcha.aspx/

I have a simple approach to stopping spammers which is 100% effective, at least in my experience, and avoids the use of reCAPTCHA and similar approaches. I went from close to 100 spams per day on one of my sites' html forms to zero for the last 5 years once I implemented this approach.
another option is what I did is to use a hide field and put the time stamp on it and then compare to the time stamp on the PHP side, if it was faster than 15 seconds (depends on how big or small is your forms) that was a bot...

Taking clue from the suggestions above, I am just putting a ready code for you to use.
HTML
<form id="form" method="post" name="form" action="send.php">
<input id="name" type="text" name="name"/>
<input id="company" type="text" name="company"/>
<input id="email" type="text" name="email"/>
<input id="checkbot" type="hidden" name="timestamp" value="" />
<input id="phone" type="text" name="phone"/>
<input id="location" type="text" name="location"/>
<textarea name="message" id="message" rows="10"></textarea>
<input class="submit" type="submit" value="send" name="submit"></input>
</form>
Javascript
<script type="text/javascript">
$(document).ready(function () {
/*Set current time on the hidden field.*/
$('#checkbot').val($.now());
$('#form').ajaxForm({
beforeSubmit: validate

function validate(formData, jqForm, options) {
var name = $('input[name=name]').fieldValue();
var email = $('input[name=email]').fieldValue();
var company = $('input[name=company]').fieldValue();
var location = $('input[name=location]').fieldValue();
var phone = $('input[name=phone]').fieldValue();
var message = $('textarea[name=message]').fieldValue();

In theory it can be used to send spam, because there are only checks if fields have values and as long the fields have a value, it does not care whether the input was human or a bot. You could improve the security by adding captcha codes (http://www.captcha.net/), to validate if an individual filling in your form is a human.
