Question

我一直试图制作一个按钮来播放音乐，并在单击时停止播放音频，但是无法使其正常工作。请需要帮助

let audio, playBtn;
playBtn = document.querySelector("#playPauseBtn");

const playPause = () => {
  audio = new Audio();
  audio.paused = true;
  audio.src = "music/amor.mp3";
  if (audio.paused === true) {
    audio.play();
    audio.paused = false;
    playBtn.innerHTML = "Pause";

  } else if (audio.paused === false) {
    audio.pause();
    playBtn.innerHTML = "Play";

  }
}
playBtn.addEventListener("click", playPause);

Answer 1

正如@christopher_pk指出的那样，您每次都在创建一个新的音频对象，该对象将在您每次按下按钮时将音频重置为开头。而是在外部声明音频：

eval

let audio, playBtn;
playBtn = document.querySelector("#playPauseBtn");

audio = new Audio();
audio.paused = true;
audio.src = "https://www.random.org/audio-noise/?channels=2&volume=100&rate=16000&size=8&date=2018-07-06&format=wav&deliver=browser";

const playPause = () => {
    if (audio.paused === true) {
        audio.play();
        audio.paused = false;
        playBtn.innerHTML = "Pause";
    } else if (audio.paused === false) {
        audio.pause();
        playBtn.innerHTML = "Play";
    }
}
playBtn.addEventListener("click", playPause);

音频播放并单击停止
