HTMLMediaElement.autoplay

The HTMLMediaElement.autoplay property reflects the autoplay HTML attribute, indicating whether playback should automatically begin as soon as enough media is available to do so without interruption.

A media element whose source is a MediaStream and whose autoplay property is true will begin playback when it becomes active (that is, when MediaStream.active becomes true).

This is the least-worst way to automatically play media content. In most cases, you shouldn't automatically play content at all, instead allowing the user to control when playback begins. However, if you need this functionality, use autoplay to do so.

Syntax

HTMLMediaElement.autoplay = true | false;

var autoplay = HTMLMediaElement.autoplay;

Value

A Boolean whose value is true if the media element will begin playback as soon as enough content has loaded to allow it to do so without interruption.
