CameraControl.onClosed

Non-standard
This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

This API is available on Firefox OS for privileged or certified applications only.

Summary

The onClosed property is used to set an event handler that will track when a new CameraControl object in the same app takes over the camera.

Syntax

instanceOfCameraControl.onClosed = funcRef;

Where funcRef is a function to be called when the camera is taken over by another CameraControl object.

Example

var options = {
  camera: navigator.mozCameras.getListOfCameras()[0]
};
 
function onSuccess( camera ) {
  camera.onClosed = function () {
    console.log("This object is no longer able to use that camera");
  }
};

navigator.mozCameras.getCamera(options, onSuccess)

Specification

Not part of any specification; however, this API should be removed when the WebRTC Capture and Stream API has been implemented.
