弹出窗口始终位于顶部

我正在研究可能使窗口始终位于顶部的任何黑客（除了window.focus（））之外。也许一个隐藏的文本框，我可以设置焦点等。

Am looking at whatever hacks that are possible to keep a window always on top (apart from window.focus()). Maybe a hidden textbox to which I can set focus etc.

每当有新消息到达时，我都会在LivePerson（支持）中看到这种情况。我有合法的使用这个，而不是惹恼用户广告或任何东西。

I see this happening in LivePerson (support) whenever a new message arrives. I have legitimate use of this and not to annoy users with ads or anything.

任何浏览器的任何黑客都会做。我不是在寻找一个完整的跨浏览器解决方案。我认为window.focus可以用于Internet Explorer，但我还没有测试它。

Any hacks for any browsers will do. I am not looking at a complete cross-browser solution. I think window.focus would work for Internet Explorer, though I am yet to test it.
