HTML5 audio player error: "The provided double value is non-finite"

Question

在 THIS 页面上制作了自定义 HTML 5 音频播放器 "handler":

<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>

我写了这个小脚本来将实际播放器绑定到 "handle":

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，出现此错误："Uncaught TypeError: Failed to set the 'volume' property on 'HTMLMediaElement': The provided double value is non-finite."

它的原因是什么？

Answer 1

您的音量参数实际上是一个事件：

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

Answer 2

对于 html5 audio.volume 方法，您必须将值除以 100。

function setVolume(e) {
   var volume = e.target.value / 100;
   music.volume = parseFloat(volume);
}

Answer 3

这个问题恰好与parseFloat或提供的值无关如果您尝试将音量或任何属性（如 currentTime,..）设置为 NAN，您将遇到相同的错误，因此简单的解决方案是检查宽度 isNaN()

function setVolume(volume) {
   if (isNaN(volume)) {
      volume= 0.1;
   }
   music.volume = parseFloat(volume);
}

Answer 4

在此处进行一些回复并展示对我有用的内容。简而言之，您必须为有时神秘设置的越界值创建一些异常，然后将其转换为字符串以准备最终转换为浮点数。我不知道为什么会这样，但确实如此。

const setVolume = (x) => {

//cap max at 100 in case of glitches
let varx = x > 100 ? 100 : x 

let volume = varx / 100;

//reset min to 0 in case of glitches
if (isNaN(volume)) { 
  volume= 0.1;
}

//convert it to a string first, and then run parseFloat
music.volume = parseFloat(volume.toString());

}
