Previous Question Next Question

To prevent a form from submitting when a user presses the Enter key in a text field, you can add an event listener to the text field that intercepts the "keydown" event and checks if the pressed key is "Enter". If it is, you can call `event.preventDefault()` to stop the form submission.

<!-- BEGIN COPY / PASTE -->
        document.getElementById('myTextField').addEventListener('keydown', function(event) {
            if (event.key === 'Enter') {
                event.preventDefault();
            }
        });
        <!-- END COPY / PASTE -->

Additional Comment:

Ensure the text field has an ID, such as "myTextField", that matches the ID used in the JavaScript.
The "keydown" event is used to detect when a key is pressed down.
`event.key` is checked for "Enter" to identify the Enter key press.
`event.preventDefault()` stops the default action, which is form submission in this context.
