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
).
Note: Sites which automatically play audio (or videos with an audio track) can be an unpleasant experience for users, so it should be avoided when possible. If you must offer autoplay functionality, you should make it opt-in (requiring a user to specifically enable it). However, autoplay can be useful when creating media elements whose source will be set at a later time, under user control.
For a much more in-depth look at autoplay, autoplay blocking, and how to respond whena autoplay is blocked by the user's browser, see our article Autoplay guide for media and Web Audio APIs.
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.
Note: Some browsers offer users the ability to override autoplay
in order to prevent disruptive audio or video from playing without permission or in the background. Do not rely on autoplay
actually starting playback and instead use play
event.
