如何设置一个按钮，让它在每次点击时都播放音频？

<button id="playButton">点击播放音频</button>
<audio id="audioPlayer" src="audio.mp3"></audio>

// 获取按钮和音频元素
var playButton = document.getElementById("playButton");
var audioPlayer = document.getElementById("audioPlayer");

// 绑定按钮的点击事件
playButton.addEventListener("click", function() {
  // 播放音频
  audioPlayer.play();
});

#playButton {
  padding: 10px 20px;
  background-color: #007bff;
  color: #fff;
  border: none;
  border-radius: 5px;
  cursor: pointer;
}
