ServiceWorkerGlobalScope: push event - Web APIs 编辑

The push event is sent to a service worker's global scope (represented by the ServiceWorkerGlobalScope interface) when the service worker has received a push message.

Example

This example sets up a handler for push events that takes JSON data, parses it, and dispatches the message for handling based on information contained within the message.

self.addEventListener("push", event => {
  let message = event.data.json();

  switch(message.type) {
    case "init":
      doInit();
      break;
    case "shutdown":
      doShutdown();
      break;
  }
}, false);
