AudioContext.onstatechange
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
JavaScript
Copy Code
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.
JavaScript
Copy Code
audioCtx.onstatechange = function() { console.log(audioCtx.state); }
