My code is shown below.
PHP

You can use AJAX to achieve the dynamic loading of the data.An Example would be:
$.ajax({
url: "yourscript.php",
cache: false,
success: function(html){
$("#results").append(html);
}
});
where yourscript.php is your backend script, where the database calls would be executed and returned back to your success on successful request.
Please note that the data should be exchanged in a serialized format(for AJAX requests the most common approach is JSON).

You can achieve this by json. Try the following code.
PHP Code
<?php
include 'Connection.php';
$userid = $_GET['userid'];
$fetchquery = mysqli_query($connect,"select * from `registration` where `Emp_Code` = '$userid'");
if (mysqli_num_rows($sql)>0)
{
while ($row=mysqli_fetch_array($fetchquery))
{
$return['employeecode']=$row['Emp_Code'];
$return['fullname']=$row['Full_Name'];
$return['permanentaddress']=$row['Permanent_Address'];
$return['mobileno']=$row['Mobile_No'];
}
}
echo json_encode($return);
Javascript Code
$("#Fetchdetails").click(function(e) {
e.preventDefault();
var userId = $(this).attr('data-user-id');
$.ajax({
type: "GET",
url : 'http://localhost/test/get_data.php?userid='+userId,
dataType : 'json',
success : function(response) {
$('#permanentaddress').val(response.permanentaddress);
$('#employeecode').val(response.employeecode);
$('#fullname').val(response.fullname);
$('#mobileno').val(response.mobileno);
},
error : function() {
alert('There was an error');
}
});
});
Note : you have to replace following line with your php file url.
