Question

i'm working on a a website and i've made a php file that will show my search results, (i'm working on request appointment) so when i click that it works but the only problem is my webpage refresh and it shows a blank page until i click on home button to redirect
// my research loop...
if(isset($_GET['submit-search'])) {
$search = mysqli_real_escape_string($conn, $_GET['search']);
$sql = "SELECT * FROM doctor WHERE DoctorFullName LIKE '%$search%' OR DoctorLocation LIKE '%$search%' OR DoctorSpeciality LIKE '%$search%'";
$result = mysqli_query($conn, $sql);
$queryResult = mysqli_num_rows($result);
if ($queryResult > 0) {
?>
<div class="container overflow">
<div class="container overflow">
<span class="mentor">
<h2 class="display Text-mentor">
<span class="mentor-admin">If the result shown bellow not seems like what you need then ;</span>
<span class="mentor-admin-quote">select the speciality of the doctor you need and your insurance, and <span class="turquoise">search</span> again</span>
</h2>
</span>
</div>
<div class="container overflow">
<p class="p-about-results"><?php echo "There is ".$queryResult." result matching your search"?></p>
<p class="p-about-results">we hope that these results are the ones you are looking for :</p>
</div>
<?php
while ($row = mysqli_fetch_assoc($result)) :
?>
// my calendar for so i can submit appointment
<div id="myModal" class="modal">
<!-- Modal content -->
<div class="modal-content">

<form>
<input type="text" name="ap-time" id="t1" class="modal-input-text" placeholder="Choose a date">

</div>
</div>
//Ajax code that i've been working on
<script type="text/javascript">
$(document).ready(function(){
//alert("jquery is working");
$(".input-requestdate").click(function(){
var name = $(".modal-input-text").val();
$.ajax({
url: "Appointment.php",
type: "POST",
async: false,
data: {
"done": 1,
"message": name,
