How to prevent users from submitting a form by hitting Enter with JavaScript?

To prevent users from submitting a form by hitting Enter with JavaScript, we can check the keyCode and keyIdentifier properties.

For instance, we write

window.addEventListener(
  "keydown",
  (e) => {
    if (
      e.keyIdentifier === "U+000A" ||
      e.keyIdentifier === "Enter" ||
      e.keyCode === 13
    ) {
      e.preventDefault();
      return false;
    }
  },
  true
);

to listen to the keydown event on the page with addEventListener.

In the keydown listener function, we check for the enter key press with

e.keyIdentifier === "U+000A" || e.keyIdentifier === "Enter" || e.keyCode === 13

If any of them is true, then we call preventDefault to stop the submission.

Conclusion

To prevent users from submitting a form by hitting Enter with JavaScript, we can check the keyCode and keyIdentifier properties.
