window.Notification实现桌面通知

var popNotice = function() {
        if (Notification.permission == "granted") {
            var notification = new Notification("Hi，", {
                body: '可以加你为好友吗？',
                icon: '/static/cute.gif'
            });
            
            notification.onclick = function() {
                alert('***已于' + new Date().toTimeString().split(' ')[0] + '加你为好友！');
                notification.close();    
            };
        }    
    };

    if (window.Notification) {
        if (Notification.permission == "granted") {
            popNotice();
        }else if( Notification.permission != "denied"){
            Notification.requestPermission(function (permission) {
              popNotice();
            });
        }
    } else {
        alert('浏览器不支持Notification');    
    }
