You could do this using WebSockets, but that requires both a server implementation and a web browser that supports it.

您可以使用WebSockets执行此操作,但这需要服务器实现和支持它的Web浏览器。

Another technique is to use Long Polling, but again, this requires work on both the client and the server. The advantage is that this is a cross browser compatible technique.

另一种技术是使用长轮询,但同样需要在客户端和服务器上工作。优点是这是一种跨浏览器兼容的技术。

I agree with Josh that WebSockets would be worth looking into, however if you don't have access to the server you could use something like Firebase for the back end.

我同意Josh认为WebSockets值得研究,但是如果你无法访问服务器,你可以使用像Firebase这样的后端。

Read into Long Polling. It's what facebook uses. Basically your client makes one Ajax call and nothing gets returned until there is data to push to it. I'm pretty sure it requires some custom server configuration so if you're developing on shared hosting it isn't going to cut it. Long Polling would be the right, albeit, more complicated way of doing this if efficiency is what you want.

阅读Long Polling。这是facebook使用的。基本上,您的客户端进行一次Ajax调用,并且在有数据要推送之前不会返回任何内容。我很确定它需要一些自定义服务器配置,所以如果你在共享主机上开发它不会削减它。如果效率是您想要的,那么长轮询将是正确的,尽管是更复杂的方式。

Server-Sent Events seems to be another option.
