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.
The ended
event is only sent to a node configured to loop automatically when the node is stopped using its stop()
method. This is the case, for example, when using an AudioBufferSourceNode
with its loop
property set to true
.
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; }

[1] Chrome and Opera don't yet implement the AudioScheduledSourceNode
interface, so this event handler is instead provided directly by the concrete interface, such as ConstantSourceNode
or AudioBufferSourceNode
.
