HTML5 音频播放器错误：“提供的双精度值是非有限的”

Question

在这个页面上有一个自定义的 HTML 5 音频播放器“处理程序”：

<div class="default-player">
    <audio controls="" autoplay="" name="media" id="audio_player">
        <source src="http://stream.radio.co/sedf8bacc9/listen" type="audio/mpeg">
    </audio>
</div>

<div id="audioplayer">
    <button id="pButton" class="pause"></button>
    <div id="timeline">
        <div id="playhead"></div>
    </div>
    <div id="volume_control">
        <label id="rngVolume_label" for="rngVolume">Volume:</label>
        <input type="range" id="rngVolume" min="0" max="1" step="0.01" value="1">
    </div>
    <div class="current-piece">
        <div class="now-playing">Now playing:</div>
        <script src="https://public.radio.co/embed/sedf8bacc9/song.js"></script>
    </div>
</div>

我编写了这个小脚本来将实际玩家绑定到“手柄”：

function radioPlayer(){

    var music = document.getElementById('audio_player');

    function playAudio() {
      if (music.paused) {
        music.play();
        pButton.className = "";
        pButton.className = "pause";
      } else {
        music.pause();
        pButton.className = "";
        pButton.className = "play";
      }
    }

    function setVolume(volume) {
       music.volume = volume;
    }

    $('#pButton').on('click', playAudio);

    $('#rngVolume').on('change', setVolume);

}

radioPlayer();

当我使用音量范围输入时，我收到此错误：“未捕获的类型错误：无法在 'HTMLMediaElement' 上设置 '音量' 属性：提供的双精度值是非有限的。”

它的原因是什么？

Answer 1

Your volume argument was in fact an event:

function setVolume(e) {
   var volume = e.target.value;
   music.volume = parseFloat(volume);
}
