AudioScheduledSourceNode.onended

The onended event handler for the AudioScheduledSourceNode interface specifies an EventHandler to be executed when the ended event occurs on the node. This event is sent to the node when the concrete interface (such as AudioBufferSourceNode, OscillatorNode, or ConstantSourceNode) determines that it has stopped playing.

Syntax

AudioScheduledSourceNode.onended = EventHandler;

Value

A function which is called by the browser when the ended event occurs on the AudioScheduledSourceNode. The function receives as input a single parameter, which is an object of type Event describing the event that occurred.

Example

In this simple example, an event listener for the ended event is set up to enable a "Start" button in the user interface when the node stops playing.

node.onended = function(event) {
  document.getElementById("startButton").disabled = false;
}
