This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The HTMLMediaElement.play() method attempts to begin playback of the media and returns a Promise which is fulfilled when the playback has been successfully started, and which is rejected if playback fails to begin for any reason (such as permission issues or other problems).
Syntax
HTMLMediaElement.play().then(function() { ... }
Parameters
None.
Return value
A Promise which is fulfilled when playback has been started, or is rejected if for any reason playback cannot be started.
Exceptions
The promise's rejection handler is called with an exception as its input value (as opposed to a traditional exception being thrown). Possible exceptions include:
NotAllowedError- The user agent (browser) or operating system doesn't allow playback of media in the current context or situation. This may happen, for example, if the browser requires the user to explicitly start media playback by clicking a "play" button.
NotSupportedError- The media source (which may be specified as a
MediaStream,MediaSource,Blob, orFile, for example) doesn't represent a supported media format.
Other exceptions may be reported, depending on browser implementation details, media player implementation, and so forth.
