    Example

    Assume that basic HTML

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

    It's possible to send a notification as followed

    function notifyMe() {
      // Let's check if the browser support notifications
      if (!"Notification" in window) {
        alert("This browser does not support desktop notification");
      }
    
      // Let's check if the user is okay to get some notification
      else if (Notification.permission === "granted") {
        // If it's okay let's create a notification
        var notification = new Notification("Hi there!");
      }
    
      // Otherwise, we need to ask the user for it's permission
      // Note, Chrome does not implement the permission static property
      // So we have to check for NOT 'denied' instead of 'default'
      else if (Notification.permission !== 'denied') {
        Notification.requestPermission(function (permission) {
    
          // Whatever the user answers, we make sure Chrome store the information
          if(!('permission' in Notification)) {
            Notification.permission = permission;
          }
    
          // If the user is okay, let's create a notification
          if (permission === "granted") {
            var notification = new Notification("Hi there!");
          }
        });
      }
    
      // At last, if the user already denied any notification, and you 
      // want to be respectful there is no need to bother him any more.
