javascript - 设置 HTML5 音频位置

Question

如何跳转到 HTML5 Audio 元素中的特定时间偏移量？

他们说你可以简单地设置他们的 currentTime property (强调我的):

The currentTime attribute must, on getting, return the current playback position, expressed in seconds. On setting, if the media element has a current media controller, then it must throw an INVALID_STATE_ERR exception; otherwise, the user agent must seek to the new value (which might raise an exception).

唉，它似乎不起作用(我在 Chrome 中需要它)。

有类似的问题，虽然没有答案。

要跳转音频文件，您的服务器必须正确配置。

客户端发送byte range requests寻找和播放文件的某些区域，因此服务器必须充分响应:

In order to support seeking and playing back regions of the media that aren't yet downloaded, Gecko uses HTTP 1.1 byte-range requests to retrieve the media from the seek target position. In addition, if you don't serve X-Content-Duration headers, Gecko uses byte-range requests to seek to the end of the media (assuming you serve the Content-Length header) in order to determine the duration of the media.

然后，如果服务器正确响应字节范围请求，您可以通过currentTime设置音频的位置:

audio.currentTime = 30;

参见 MDN 的 Configuring servers for Ogg media (实际上，这同样适用于其他格式)。
