What are some best practices for executing JavaScript without displaying the URL in the address bar?

When executing JavaScript without displaying the URL in the address bar, one common approach is to use AJAX to send a request to a PHP script that will handle the JavaScript execution. This way, the URL in the address bar will not change as the JavaScript code is executed on the server side. 

<?php
// index.php

if(isset($_POST['execute_js'])) {
    // Execute JavaScript code here
    echo "<script>alert('JavaScript executed without changing URL');</script>";
    exit;
}
?>

<!DOCTYPE html>
<html>
<head>
    <title>Execute JavaScript without displaying URL</title>
</head>
<body>
    <button id="execute_js_btn">Execute JavaScript</button>
    
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <script>
        $(document).ready(function() {
            $('#execute_js_btn').click(function() {
                $.ajax({
                    url: 'index.php',
                    method: 'POST',
                    data: { execute_js: true },
                    success: function(response) {
                        // Handle response if needed
                    }
                });
            });
        });
    </script>
</body>
</html>
