ipad - setMuted 或 setVolume 在 iPad 上的 MediaElement.js 中不起作用

Question

似乎音量控制和静音/取消静音都不能在 iPad 上工作。以前有人遇到过这个问题吗？非常简单的功能，没有错误，只是静默失败。

var 播放器；
$(文档).ready(函数 () {
    player = new MediaElementPlayer('#player', {});
});
功能静音（）{
    player.setMuted（真）
    // player.setVolume(0) 在 iPad 上也不起作用

}
功能取消静音（）{
    player.setMuted（假）
}

HTML：

 <audio id="player" controls="controls">
<source type="audio/mp3" src="intro.mp3" /> </audio>

Answer 1

Nevermind. Since MediaElement.js uses native <audio> controls on iPad, according to Safari HTML5 Audio and Video guide, it is not possible to control HTML5 audio volume via script:

On iOS devices, the audio level is always under the user’s physical control. The volume property is not settable in JavaScript. Reading the volume property always returns 1.

... need to program a workaround for iPads.
