class Audio

A AudioTrackList that lists the AudioTrack objects contained in the element.

A Boolean that reflects the autoplay HTML attribute, indicating whether playback should automatically begin as soon as enough media is available to do so without interruption. 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, this can be useful when creating media elements whose source will be set at a later time, under user control.

Returns a Node representing the next node in the tree, or null if there isn't such node.

Returns a DOMString containing the name of the Node. The structure of the name will differ with the node type. E.g. An HTMLElement will contain the name of the corresponding tag, like 'audio' for an HTMLAudioElement, a Text node will have the '#text' string, or a Document node will have the '#document' string.

Returns an unsigned short representing the type of the node. Possible values are:
