How to detect Enter

document.addEventListener('keydown', (event) => {
  if (event.key === "Enter" && !event.isComposing) {
    // Enter was pressed
  }
});

Use event.key to react to what the key means (it follows the keyboard layout) and event.code for its physical position, for example WASD in games. keyCode and which are deprecated: they still work, but their values differ between browsers and layouts.

How browsers treat Enter

Enter submits a form when focus is in a text input, and activates buttons and links. Check event.isComposing: while someone types in Chinese, Japanese or Korean, Enter confirms the composition and shouldn’t trigger your action. The numpad Enter has the same key but code NumpadEnter.

<input onKeyDown={(e) => { if (e.key === "Enter") { /* … */ } }} />

13. It’s deprecated, though: use event.key (“Enter”) or event.code (Enter) in new code.
What is the difference between event.key and event.code?
event.key is the character or action the key produces with the current layout; event.code is the physical key position, the same on every layout.
Should I use keydown or keypress?
keydown. The keypress event is deprecated and doesn’t fire for keys that don’t produce characters, such as Escape or the arrow keys.
