How do I work with forms using JavaScript?

Answer

To work with forms using JavaScript, you can manipulate form elements, validate input, and handle form submissions. Here's a basic example of handling a form submission and preventing the default behavior.

<!-- BEGIN COPY / PASTE -->
        <form id="myForm">
            <input type="text" id="name" placeholder="Enter your name" required>
            <button type="submit">Submit</button>
        </form>

        <script>
            document.getElementById('myForm').addEventListener('submit', function(event) {
                event.preventDefault(); // Prevents the default form submission
                const name = document.getElementById('name').value;
                console.log('Form submitted with name:', name);
            });
        </script>
        <!-- END COPY / PASTE -->

Additional Comment:

The "submit" event listener is added to the form to intercept the submission.
"event.preventDefault()" is used to stop the form from submitting in the traditional way, allowing you to handle it with JavaScript.
The value of the input field is accessed using "document.getElementById('name').value".
You can further process the form data or send it to a server using AJAX.
