Use the EventTarget.addEventListener() method to listen for keyup/keydown event. And check the keyCode‘s value to see if an Enter key is pressed.
Enter key keycode is 13.
Example detect Enter keypress in JavaScript
HTML example code checks whether the Enter key is pressed or not.
<!DOCTYPE html>
<html>
<body>
<script>
document.addEventListener("keyup", function(event) {
if (event.keyCode === 13) {
alert(event.key + event.keyCode);
}
});
</script>
</body>
</html>
Output:
Use the KeyboardEvent.key attribute similarly.
document.addEventListener("keyup", function(event) {
if (event.key === 'Enter') {
alert('Enter is pressed!');
}
});
