建议我...刷新页面 [英] Suggest me... for refreshing the page

问题描述

我尝试一个简单的聊天..通过使用gridview



每当我刷新页面意味着它只显示gridview中的发件人消息..

我使用'

< meta http-equiv =REFRESHcontent =1/>



我的想法是当我将光标输入文本框时意味着它不会刷新页面。

按下发送按钮意味着它将会明星刷新页面..

after pressing the send button mean it will star to refreshing the page..

推荐答案

使用刷新页面开发基于Web的聊天系统，期待来自其他玩家，计时器或其他一些事件的回复真的是抑郁的事情。如果没有更新，那就浪费了流量，如果有，你可能会有点太晚了。这都错了。显然，Web主要基于纯客户端 - 服务器技术（拉技术）和无状态协议，纯粹适用于如此明显的任务，如聊天。在某些背景下，请参阅我过去的答案：网站帐户的应用程序'信息中心' / a> [ ^ ]。



但问题确实存在一些更好的解决方案：你需要服务器推送：http://en.wikipedia.org/wiki/Server_push [ ^ ]。



这些天，聊天系统等问题通常都是通过这样的方式解决的推送产品作为SignalR：

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:
