        return;
    }
    var notification;
    // 检查用户曾经是否同意接受通知
    if (Notification.permission === 'granted') {
        notification = new Notification(title, options); // 显示通知
        console.log("浏览器禁止了notify");
    } else {
        Notification.requestPermission();
    }
    if (notification && callback) {
        notification.onclick = function(event) {
            callback(notification, event);
        }
        setTimeout(function () {
