我想使用 wavesurfer.js 添加数字音频文件的时间线,不幸的是我的代码不起作用。我可以知道从哪里可以加载我的文件的timeline.js 吗? Wavesurfer 时间线插件是否已弃用?

<!-- main wavesurfer.js lib -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/wavesurfer.js/1.2.3/wavesurfer.min.js"></script>

<!-- wavesurfer.js timeline -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/wavesurfer.js/1.2.3/plugin/wavesurfer.timeline.min.js"></script>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<body>
<div id="waveform-timeline"></div>
<div id="audio-spectrum"></div>
</body>
</html>

JavaScript:

var Spectrum = WaveSurfer.create({
container: '#audio-spectrum',
progressColor: "#03a9f4",
container: document.querySelector('#audio-spectrum'),
backend: 'MediaElement'
});

Spectrum.on('ready', function () {
var timeline = Object.create(Spectrum.Timeline);

timeline.init({
Spectrum: Spectrum,
container: "#wave-timeline"
});
});

// Load the audio file from your domain !
Spectrum.load('http://ia902606.us.archive.org/35/items/shortpoetry_047_librivox/song_cjrg_teasdale_64kb.mp3');

错误表明wavesurfer未定义。

最佳答案

时间线插件要求您将 wavesurfer 实例传递给其 create 函数。您正在将其传递到键 Spectrum 下 - 这就是它无法找到的原因。将时间线初始化代码更改为:

// ...
timeline.init({
wavesurfer: Spectrum,
container: "#wave-timeline"
});
// ...
