有哪些方法可以显示来自Web应用程序的桌面通知？

// request permission on page load
document.addEventListener(\'DOMContentLoaded\', function () {
  if (Notification.permission !== \"granted\")
    Notification.requestPermission();
});

function notifyMe() {
  if (!Notification) {
    alert(\'Desktop notifications not available in your browser. Try Chromium.\'); 
    return;
  }

  if (Notification.permission !== \"granted\")
    Notification.requestPermission();
  else {
    var notification = new Notification(\'Notification title\', {
      icon: \'http://cdn.sstatic.net/stackexchange/img/logos/so/so-icon.png\',
      body: \"Hey there! You\'ve been notified!\",
    });

    notification.onclick = function () {
      window.open(\"https://stackoverflow.com/a/13328397/1269037\");      
    };

  }

}

<button onclick=\"notifyMe()\">Notify me!</button>
