"Autoplay" HTML5 audio player on mobile browsers
提问by Joseph Sikorski
I am creating a HTML5 music website for mobile users.The goal is to get it running completely in mobile browsers..
The issue is that when a user selects a track to play, they are taken to the "player" page.I then AJAX in a HTML5 audio element in with the autoplay attribute set to true. This works great on desktops, not so much on mobile.
The track is not playing though once this page is reached, and the user instead needs to explicitly click play from this player page in order for audio playback to start.
Any ideas on how I can adjust my flow in order for audio playback to autoplayafter loading the playing page?
我正在为移动用户创建一个 HTML5 音乐网站。目标是让它在移动浏览器中完全运行。
问题是当用户选择要播放的曲目时，他们被带到“播放器”页面。然后是 AJAX在将 autoplay 属性设置为 true 的 HTML5 音频元素中。这在台式机上效果很好，而在移动设备上则不然。
尽管到达此页面后曲目不会播放，但用户需要从此播放器页面明确单击播放才能开始音频播放。关于如何调整我的流程以便在加载播放页面后自动播放音频播放的任何想法？

This question has been answered in other places before.
这个问题之前在其他地方已经回答过了。
Regarding Apple devices specifically:
特别是关于苹果设备：
- Can you autoplay HTML5 videos on the iPad?
- "Apple has made the decision to disable the automatic playing of video on iOS devices, through both script and attribute implementations. In Safari, on iOS (for all devices, including iPad), where the user may be on a cellular network and be charged per data unit, preload and auto-play are disabled. No data is loaded until the user initiates it."
- Safari HTML5 Audio and Video Guide - iOS-Specific Considerations
- "In Safari on iOS (for all devices, including iPad), where the user may be on a cellular network and be charged per data unit, preload and autoplay are disabled. No data is loaded until the user initiates it. This means the JavaScript play() and load() methods are also inactive until the user initiates playback, unless the play() or load() method is triggered by user action. In other words, a user-initiated Play button works, but an onLoad="play()" event does not."
- 您可以在 iPad 上自动播放 HTML5 视频吗？
- “Apple 已决定通过脚本和属性实现在 iOS 设备上禁用视频的自动播放。在 Safari 中，在 iOS 上（适用于所有设备，包括 iPad），用户可能使用蜂窝网络并被收费每个数据单元，预加载和自动播放被禁用。在用户启动之前不会加载任何数据。”
- Safari HTML5 音频和视频指南 - 特定于 iOS 的注意事项
- “在 iOS 上的 Safari（适用于所有设备，包括 iPad）中，用户可能使用蜂窝网络并按数据单位收费，预加载和自动播放被禁用。在用户启动之前不会加载数据。这意味着 JavaScript play() 和 load() 方法在用户启动播放之前也处于非活动状态，除非 play() 或 load() 方法由用户操作触发。换句话说，用户启动的播放按钮有效，但 onLoad=" play()”事件没有。”
Googling will reveal more.
谷歌搜索会发现更多。
I have read in a few places that Chrome on Android also behaves this way, though other Android browsers may not.
我在一些地方读到 Android 上的 Chrome 也有这种行为，尽管其他 Android 浏览器可能不会。
How this applies to your case specifically:
这具体如何适用于您的案例：
Normally, just clicking on a link would work fine if the player were in the same page, since the click on that link would be counted as valid user interaction to start the media playback. But, you're loading a new page, which resets this check for user interaction, and so media will not start until the user interacted with the new page in some way. Thus, the user has to scroll, touch, tap, swipe, or something, in order to auto play, or just hit the play button on the media player.
通常，如果播放器在同一页面中，只需点击链接就可以正常工作，因为点击该链接将被视为开始媒体播放的有效用户交互。但是，您正在加载一个新页面，这会重置此对用户交互的检查，因此在用户以某种方式与新页面交互之前，媒体不会启动。 因此，用户必须滚动、触摸、点击、滑动或其他操作才能自动播放，或者只需点击媒体播放器上的播放按钮。
