您可以检查该事件是否是 MouseEvent 的实例或KeyboardEvent .

function advance(event) {
  if (event instanceof MouseEvent) {
    console.log('clicked');
  } else if (event instanceof KeyboardEvent && event.keyCode === 13) {
    console.log('enter');
  }
}

window.addEventListener('keypress', advance);

div {
  width: 100px;
  height: 100px;
  background: #F00;
}

<div onclick="advance(event)"></div>
