更改 src和javascript

Question

我有多个音频文件，要根据用户选择流式传输。我怎么做？到目前为止，这是我所拥有的，而且似乎没有用。

*更新：进行了一些更改，现在声称它audio.load();不是功能。谁能告诉我为什么呢？本规范已更新以反映更改。

JavaScript：

function updateSource(){ 
    var audio = document.getElementById('oggSource');
    audio.src = 
        'audio/ogg/' + 
        document.getElementById('song1').getAttribute('data-value');
    audio.load();
}

HTML：

<audio id="audio" controls="controls">
    <source id="oggSource" src="" type="audio/ogg"></source>
    <source id="mp3Source" type="audio/mp3"></source>
        Your browser does not support the audio format.

<ul style="list-style: none">
    <li>Sunday May 27, 2012
        <ul style="display: none">
            <li id="song1" data-value="song1.ogg">
                <button onclick="updateSource();">Item1</button>
            </li>
            <li>Item2</li>
            <li>Item3</li>
        </ul>
    </li>
</ul>

Item2当Item3我单击它们时，我将要播放其他音频文件。

Answer 1

试试这个片段

list.onclick = function(e) {

  e.preventDefault();



  var elm = e.target;

  var audio = document.getElementById('audio');



  var source = document.getElementById('audioSource');

  source.src = elm.getAttribute('data-value');



  audio.load(); //call this to just preload the audio without playing

  audio.play(); //call this to play the song right away

};
