How can I handle asynchronous form submissions in my web app?

You can use AJAX to send form data to the server without reloading the page. Would you like a code example?

Yes, please provide a code example for that.

Here's a simple example using jQuery:

$('#myForm').submit(function(event) {
    event.preventDefault(); // Prevent the default form submission
    $.ajax({
        url: '/submit',
        type: 'POST',
        data: $(this).serialize(),
        success: function(response) {
            alert('Form submitted successfully!');
        },
        error: function() {
            alert('There was an error submitting the form.');
        }
    });
});

What if I want to show a loading spinner while the form is submitting?

You can show a loading spinner by adding a line to display it before the AJAX call and hiding it in the success/error callbacks.
