javascript - jQuery:多个音频播放器按钮

Question

我想制作 4 个播放 mp3 音频的播放按钮。播放功能每 4 个按钮都起作用，但不幸的是，暂停功能对它们中的任何一个都不起作用。也许暂停条件是错误的？

<div class="audio-button">
    <audio src="media/test.mp3"></audio>
</div>
<div class="audio-button">
    <audio src="media/test2.mp3"></audio>
</div>
<div class="audio-button">
    <audio src="media/test3.mp3"></audio>
</div>
<div class="audio-button">
    <audio src="media/test4.mp3"></audio>
</div>

$(document).ready(function() {
    var playing = false;

    $('.audio-button').click(function() {
        $(this).toggleClass("playing");
        var song = $(this).find('audio').attr('src');
        var audio = new Audio(song);

        if (playing == false) {
            audio.play();
            playing = true;
        } else {
            audio.pause();
            playing = false;
        }
    });
});

您需要直接从按钮中获取音频元素作为子元素并与之交互。您不需要使用构造函数克隆 Audio 对象。

$(document).ready(function() {
  var playing = false;

  // Add file names.
  $('.audio-button').each(function() {
    var $button = $(this);    
    var $audio = $button.find('audio');
    
    $($('<span>').text($audio.attr('src'))).insertBefore($audio);
  });

  // Add click listener.
  $('.audio-button').click(function() {
    var $button = $(this);    
    var audio = $button.find('audio')[0]; // <-- Interact with this!
    
    // Toggle play/pause
    if (playing !== true) {
      audio.play();
    } else {
      audio.pause();
    }

    // Flip state
    $button.toggleClass('playing');
    playing = !playing
  });
});

.fa.audio-button {
  position:      relative;
  display:       block;
  width:         12em;
  height:        2.25em;
  margin-bottom: 0.125em;
  text-align:    left;
}

.fa.audio-button:after {
  position:      absolute;
  right:         0.8em;
  content:       "\f04b";
}

.fa.audio-button.playing:after {
  content:       "\f04c";
}
