语法

myPushManager = ServiceWorker.pushManager 

一个 PushManager 对象。

示例

this.onpush = function(event) {
  console.log(event.data);
  // From here we can write the data to IndexedDB, send it to any open
  // windows, display a notification, etc.
}

navigator.serviceWorker.register('serviceworker.js').then(
  function(serviceWorkerRegistration) {
    serviceWorkerRegistration.pushManager.subscribe().then(
      function(pushSubscription) {
        console.log(pushSubscription.subscriptionId);
        console.log(pushSubscription.endpoint);
        // The push subscription details needed by the application
        // server are now available, and can be sent to it using,
        // for example, an XMLHttpRequest.
      }, function(error) {
        // During development it often helps to log errors to the
        // console. In a production environment it might make sense to
        // also report information about errors back to the
        // application server.
        console.log(error);
      }
    );
  });
