| `navigator.serviceWorker.oncontrollerchange` is the [event handler][1] that |
| must be supported as attribute by the `[ServiceWorkerContainer][2]` object. A |
| `controllerchange` event using the `[Event][3]` interface is dispatched on |
| `[ServiceWorkerContainer][2]` object (See step 7 of the [_Activation |
| algorithm][4]) when the associated Service Worker [registration][5] for the |
| document enters the [activation process][6]. When the [activation process][6] |
| is triggered by `replace()` method call within the event handler of the |
| `install` event, `navigator.serviceWorker.controller` immediately reflects the |
| [active worker][7] as the Service Worker that [controls][8] the document. |
