you can use setInterval() in javascript for it.

I won't interval.. completely stop the refreshing action

This is bad approach in principle. Please see Solution 2.

Development of the Web-based chat system using refreshing the page expecting replies from other player, on timer or some other events is really depressive thing. If there are no updates, it's a waste of traffic, if there are, you may get them a bit too late. It's all wrong. Apparently, Web, primarily based on pure client-server technology (pull technology) and stateless protocol, is purely suited for such an apparent task as chat. For some background, please see my past answer: Application 'dashboard' for website accounts[^].

But some better resolution of the problem does exist: you need server push: http://en.wikipedia.org/wiki/Server_push[^].

These days, such problems as chat systems are pretty typically solved with such a "push" product as SignalR:

This tutorial shows how to create a SignalR chat application: http://www.asp.net/signalr/overview/getting-started/tutorial-getting-started-with-signalr[^].
