Previous Question Next Question

To prevent a form submission when the Enter key is pressed, you can add an event listener to the form and check for the Enter key in the "keydown" event. If the Enter key is detected, you can call "preventDefault()" to stop the form from submitting.

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

Additional Comment:

This code snippet adds an event listener to the form element.
It listens for the "keydown" event and checks if the "Enter" key was pressed.
If the "Enter" key is pressed, "event.preventDefault()" is called to prevent the default form submission behavior.
