我在Firefox中使用Web Notifications并结合Server Sent DOM事件。不幸的是，通知在大约两到三秒后消失。我更喜欢Chrome的留言方式（在任何给定时间最多显示三个），直到用户点击通知为止。
这是我的......
window.onload = function(e)
{
if ('EventSource' in window)
{//Server Sent DOM Events
var sse = new EventSource('../mail/sse/');
if (Notification.permission && Notification.permission!='granted')
{
Notification.requestPermission(function(status) {if (Notification.permission!=status) {Notification.permission = status;}});
}
else if (window.webkitNotifications && window.webkitNotifications.checkPermission()!=0)
{
document.getElementsByTagName('body')[0].addEventListener('click',function() {window.webkitNotifications.requestPermission();},false);
}
es.onclick = function(sse)
{
//
}
//doesn't work
es.onclose = function(es) {es.preventDefault();}
es.onmessage = function(sse)
{
if ('Notification' in window)
{
if (window.webkitNotifications)
{
var n = webkitNotifications.createNotification('images/stuff.gif','New Email Message(s)',sse.data);
n.show();
n.onshow = function() {setTimeout(notification.close,15000);}
}
else
{
var n = new Notification('New Email Message(s)',{icon:'images/stuff.gif',body:sse.data});
}
}
}
}
}
