javascript - 切换播放/暂停图像按钮 HTML5 视频

Question

我有这个代码

var video = document.getElementById('player');
    video.volume = 0;
var muteBtn = document.getElementById('mute');
muteBtn.addEventListener('click',function(){
    if(video.volume == 1){ 
    video.volume = 0; 
    muteBtn.src="http://omniawebfactory.com/unik/wp-content/uploads/2016/10/sound-on-beli-1.png";
    }
    else{
        video.volume = 1;
     muteBtn.src="http://omniawebfactory.com/unik/wp-content/uploads/2016/10/sound-off-beli-1.png";
    }
});

.buttons{
display:block;
width:50px;
height:50px;
background-color:black;
float:left;
}
#control{
width:1000px;
height:50px;
clear:both;
background-color:black;
}

<div id="control">
<img class="buttons"src="http://omniawebfactory.com/unik/wp-content/uploads/2016/10/play-beli-1.png" onClick="document.getElementById('player').play();"/>
<img class="buttons" src="http://omniawebfactory.com/unik/wp-content/uploads/2016/10/pause-beli-1.png" onClick="document.getElementById('player').pause();"/>
<img class="buttons" src="http://omniawebfactory.com/unik/wp-content/uploads/2016/10/sound-on-beli-1.png" id="mute">
</div>

而且我希望播放/暂停按钮像当前的静音按钮一样切换。 https://jsfiddle.net/t6t0maw7/

我尝试复制 javascript 并使用播放/暂停功能对其进行编辑，但没有成功。自由编辑 jsfiddle.net，正确答案将被接受。

JS 代码

var playPause = document.getElementById("play-pause");

playPause.addEventListener("click", function() {
  if (video.paused == true) {
    // Play the video
    video.play();

    // Update the button text to 'Pause'
    playPause.classList.toggle('pause');
  } else {
    // Pause the video
    video.pause();

    // Update the button text to 'Play'
   playPause.classList.toggle('pause');
  }
});

CSS

button{
    height:50px;
  width:50px;  
  border:none;
  outline:none;
}

button.play{
  background:url("http://omniawebfactory.com/unik/wp-content/uploads/2016/10/play-beli-1.png");
  background-size:100%;
}
button.pause{
  background:url("http://omniawebfactory.com/unik/wp-content/uploads/2016/10/pause-beli-1.png");
  background-size:100%;
}
