MediaElementAudioSourceNode.mediaElement - Web APIs 编辑

The MediaElementAudioSourceNode interface's read-only mediaElement property indicates the HTMLMediaElement that contains the audio track from which the node is receiving audio. This stream was specified when the node was first created, either using the MediaElementAudioSourceNode() constructor or the AudioContext.createMediaElementSource() method.

Syntax

audioSourceElement = mediaElementAudioSourceNode.mediaElement;

Value

An HTMLMediaElement representing the element which contains the source of audio for the node.

Examples

const audioCtx = new window.AudioContext();
const audioElem = document.querySelector('audio');

let options = {
  mediaElement: audioElem
}

let source = new MediaElementAudioSourceNode(audioCtx, options);
console.log(source.mediaElement);
