Is it advisable to use JavaScript alongside PHP for loading form data when selecting an entry in a list?

It is advisable to use JavaScript alongside PHP for loading form data when selecting an entry in a list because JavaScript can provide a more dynamic and seamless user experience by updating the form without requiring a page reload. This can improve the overall usability of the form and make the selection process more intuitive for users. 

<?php
// PHP code to fetch data based on selected entry in a list
if(isset($_POST['selected_entry'])){
    $selected_entry = $_POST['selected_entry'];

    // Perform database query or any other necessary operation to fetch data based on the selected entry

    // Return the fetched data in JSON format
    $data = [
        'field1' => 'Value 1',
        'field2' => 'Value 2',
        'field3' => 'Value 3'
    ];

    echo json_encode($data);
    exit;
}
?>
