Question

我正在学习一些初学者的前端开发。我创建了一个非常简单的网站，该网站利用了Lightbox工具包。我已经弄清楚了当有人单击缩略图但需要一些有关如何停止它的指针时如何开始音轨的方法，或者为了获得更可靠的解决方案，如果有人单击“下一个”箭头，则播放适当的音轨。到目前为止，这是我的代码：

    <link rel="stylesheet" type="text/css" href="css/style.css">
    <link rel="stylesheet" type="text/css" href="css/lightbox.min.css">

<body bgcolor="#F7FBED  ">

<div class="gallery">
    <a href="images/drake_big.jpg" data-lightbox="mygallery" data-title="nick drake"
       onclick=PlaySound("music/drake.mp3")><img src="images/drake_small.jpg"></a>
    <a href="images/prine_big.jpg" data-lightbox="mygallery" data-title="john prine"
       onclick=PlaySound("music/prine.mp3")> <img src="images/prine_small.jpg"></a>
    <a href="images/westerberg_big.jpeg" data-lightbox="mygallery" data-title="paul westerberg"
       onclick=PlaySound("music/westerberg.mp3")> <img src="images/westerberg_small.jpg"></a>
    <a href="images/townes_big.png" data-lightbox="mygallery" data-title="townes van zandt"
       onclick=PlaySound("music/townes.mp3")> <img src="images/townes_small.jpg"></a>
    <script>
        function PlaySound(path) {
            //this function will work like a toggler for sound track playing
            var sound = document.getElementById(path);
            if(sound && sound.currentTime > 0){ //check whether it is already playing
                sound.pause();// stop the sound
                sound.currentTime = 0 //
            }else if(sound){
                //this block to play paused sound track
                sound.play();
            }else{
                //this block to play new sound track
                sound= document.createElement('audio');
                sound.setAttribute('src', path);
                sound.setAttribute('id', path);
                sound.play();
            }
        }

    </script>
</div>
</body>
</html>

我想我可以更好地利用标签？

一个简单的解决方案是：

    <script>
    function PlaySound(path) {
            //this function will work like a toggler for sound track playing
            var sound = document.getElementById(path);
            if(sound && sound.currentTime > 0){ //check whether it is already playing
               sound.pause();// stop the sound
               sound.currentTime = 0 //
            }else if(sound){
                 //this block to play paused sound track

               sound.play();
            }else{
                 //this block to play new sound track

                  sound= document.createElement('audio');
                  sound.setAttribute('src', path);
                  sound.setAttribute('id', path);
                  sound.play();
            }


    }
