推荐答案

将数据存储在xml文件或数据库中，无论您喜欢什么。您可以在刷新时重新填充字段。

还会显示警告，说明如果用户刷新页面会发生什么。

也许可以使用javascript完成但我可以不要认为你应该尝试覆盖客户端的浏览器功能。

Store the data in an xml file or database, whatever you are comfortable with. You can re populate the fields on refresh.
Also display a warning saying that what will happen if the user refreshes the page.
Maybe it can be done using javascript but I don't think you should try to overrride the client's browser funtionalities.

如果你对JQuery感到满意，那么在后台你可以将客户端数据发送到服务器以维护数据库/会话中的客户端状态。如果客户端刷新浏览器，您可以从保存在数据库/会话中的最后一个状态恢复他。对于webmethod演示，您可以参考以下链接

If you are comfortable with JQuery then at background you can send client data to server to maintain state of client in database/session. If client refreshes browser you can resume him from that last state saved in database/session. For webmethod demo you can refer following links
