The onstatechange property of the AudioContext interface defines an event handler function to be called when the statechange event fires: this occurs when the audio context's state changes.
Syntax
var audioCtx = new AudioContext();
audioCtx.onstatechange = function() { ... };
Example
The following snippet is taken from our AudioContext states demo (see it running live.) The onstatechange hander is used to log the current state to the console every time it changes.
audioCtx.onstatechange = function() {
console.log(audioCtx.state);
}
