为什么iPhone Safari上没有JavaScript .play（）音频文件？ [英] Why can't JavaScript .play() audio files on iPhone safari?

问题描述

我有一个JavaScript网络应用程序可以像这样定期播放一些音频：

I've got a JavaScript web app working that plays some audio periodically like this:

var SOUND_SUCCESS = new Audio('success.mp3');
SOUND_SUCCESS.play();

这适用于桌面浏览器（在Edge和Chrome中测试过），但它不能播放iPhone上的Safari。

This works great on desktop browsers (tested in Edge and Chrome), but it doesn't play on Safari on iPhone.

我看了看Stack Overflow，几年前我发现一些答案，除非你'不能播放Safari的音频在那个全屏播放器中。这仍然是这种情况吗？

I've looked around Stack Overflow, and I found some answers from a couple of years ago that it's not possible to play audio from Safari unless you're in that full screen player. Is this still the case?

推荐答案

iO禁用自动播放，而是要求播放作为用户交互的一部分启动（例如，你可以在touchstart监听器中开始播放）。关于 Apple的开发人员文档<有一些关于此的文档/ A>。还有一篇文章克服iOS HTML5音频限制在IBM的开发者网站上，其中包含示例和更多细节。

iOs disables autoplay, instead requiring that play be initiated as part of a user interaction (e.g., you can start playback within a touchstart listener). There's a bit of documentation about this on Apple's developer documentation. There's also this article Overcoming iOS HTML5 audio limitations on IBM's developer site that has examples and more detail.
