Css 当“我的音乐”按钮处于'；它断断续续

我有一个按钮在我的页面上开关音乐我已经用css样式，它与自定义图像出现。。。当这个按钮打开和关闭时，我可以更改它的图像吗 谢谢

这是我的音频代码

<audio id="myAudio"
                    <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.mp4"
         type='audio/mp4'>
                    <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.oga"
         type='audio/ogg; codecs=vorbis'>
                    Your user agent does not support the HTML5 Audio element.
                    </audio>
                    <script>
function aud_play_pause() {
  var myAudio = document.getElementById("myAudio");
  if (myAudio.paused) {
    myAudio.play();
  } else {
    myAudio.pause();
  }
}
</script>

只需根据您想要实现的不同外观选择两种样式即可。然后使用JQuery在上使用右键

你能试试这个吗

function aud_play_pause(d) {
  var myAudio = document.getElementById("myAudio");
  if (myAudio.paused) {
     d.className = 'soundButton';
    myAudio.play();
  } else {
     d.className = 'soundOffButton';
    myAudio.pause();
  }
}

HTML:

按如下方式修改javascript：

function aud_play_pause() {
  var myAudio = document.getElementById("myAudio");
  var myButton = document.getElementsByClassName("soundButton");
  if (myAudio.paused) {
    myAudio.play();
    myButton.style.background="background-image: url('image/speakerIconPause.png')";
  } else {
    myAudio.pause();
    myButton.style.background="background-image: url('image/speakerIconPlay.png')";
  }
}

当然，您需要两个背景图像：

• speakerIconPause.png
• speakerIconPlay.png
您可以这样做：

<audio id="myAudio">
                    <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.mp4"
         type='audio/mp4'>
                    <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.oga"
         type='audio/ogg; codecs=vorbis'>
                    Your user agent does not support the HTML5 Audio element.
                    </audio>
                    <script>
function aud_play_pause() {
  var myAudio = document.getElementById("myAudio");
  var button = document.getElementsByClassName('soundButton')[0];
  if (myAudio.paused) {
    myAudio.play();
    button.classList.remove('paused');
    button.classList.add('playing');
  } else {
    myAudio.pause();
    button.classList.remove('playing');
    button.classList.add('paused');
  }
}
</script>

您应该使用内容图像，而不是背景图像。这样做的一个原因是，只有内容图像可以有文本回退（

alt

attributes）。在播放开始时更改内容图像似乎是一件简单的事情。在任何情况下，请显示您已经尝试了什么。他没有使用jquery。他可以。这是解决这个问题的简单方法

function aud_play_pause(d) {
  var myAudio = document.getElementById("myAudio");
  if (myAudio.paused) {
     d.className = 'soundButton';
    myAudio.play();
  } else {
     d.className = 'soundOffButton';
    myAudio.pause();
  }
}

<button class="soundButton" type="button" onclick="aud_play_pause(this)"></button>

.soundOffButton{
    width:23px;
    height:18px;
    border:none;
    background:url(../../images/speakerIconOFF.png);
    padding:0;
    margin:0;
}

function aud_play_pause() {
  var myAudio = document.getElementById("myAudio");
  var myButton = document.getElementsByClassName("soundButton");
  if (myAudio.paused) {
    myAudio.play();
    myButton.style.background="background-image: url('image/speakerIconPause.png')";
  } else {
    myAudio.pause();
    myButton.style.background="background-image: url('image/speakerIconPlay.png')";
  }
}

<audio id="myAudio">
                    <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.mp4"
         type='audio/mp4'>
                    <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.oga"
         type='audio/ogg; codecs=vorbis'>

function aud_play_pause() {
  var myAudio = document.getElementById("myAudio");
  var button = document.getElementsByClassName('soundButton')[0];
  if (myAudio.paused) {
    myAudio.play();
    button.classList.remove('paused');
    button.classList.add('playing');
  } else {
    myAudio.pause();
    button.classList.remove('playing');
    button.classList.add('paused');
  }
}

.soundButton.playing {
