您可以簡單地添加這行代碼：

var myNotification = new Notification(title, options); 

我給你一個更好的例子，你要問用戶是否可以添加通知：

function notifyMe() { 
    // Let's check if the browser supports notifications 
    if (!("Notification" in window)) { 
    console.log("This browser does not support desktop notification"); 
    } 

    // Let's check whether notification permissions have alredy been granted 
    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 permission 
    else if (Notification.permission !== 'denied' || Notification.permission === "default") { 
    Notification.requestPermission(function (permission) { 
     // If the user accepts, let's create a notification 
     if (permission === "granted") { 
     var notification = new Notification("Hi there!"); 
     } 
    }); 
    } 

    // At last, if the user has denied notifications, and you 
    // want to be respectful there is no need to bother them any more. 
}
