javascript - 如何通过单击按钮切换音频播放()暂停()？

Question

我已向我的网站添加了音频，该音频在打开网站时播放。现在我想添加播放/暂停按钮来切换音频。

这是我尝试的方法:

<audio id="myAudio" autoplay >
 <source src="mp3/background-music.mp4" type='audio/mp4'>
 Your user agent does not support the HTML5 Audio element.
</audio>

<a type="button" class="play-pause" title="play/pause"><i class="fa fa-pause"></i></a>


<script type="text/javascript">
  $(document).ready(function() {
    var playing = false;

    $('a.audio-btn').click(function() {
        if (playing == false) {
            document.getElementById('myAudio').play();
            playing = true;
            $(this).text("stop sound");

        } else {
            document.getElementById('myAudio').pause();
            playing = false;
            $(this).text("restart sound");
        }
    });
  });
</script>  

但它对我不起作用。谁能告诉我我哪里出了问题？

出于演示目的，我添加了 video 标签，要处理音频，您可以将 video 替换为 audio 标签并使用

$('.play-pause')

而不是

$('a.audio-btn')

对于音频，请在 video 标记的位置使用它:

<audio id="myAudio" autoplay>
 <source src="http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4" type='audio/mp4'>
   Your user agent does not support the HTML5 Audio element.
</audio>

$(document).ready(function () {
 var playing = true;
 $('.play-pause').click(function () {
  if (playing == false) {
   document.getElementById('myAudio').play();
   playing = true;
   $(this).text("Sop Sound");

  } else {
   document.getElementById('myAudio').pause();
   playing = false;
   $(this).text("Restart Sound");
  }
 });
});

a {
  background: #000;
  color: #fff;
  cursor: pointer;
  padding: 10px;
}
video {
  width: 200px;
}
