推荐答案

您可以做到这一点，但这将涉及大量流量和不必要的通信.
最大的问题是您将需要处理客户端的事件，以将其传递到服务器.
更好的方法是确定应该在哪个原子级别上传达客户端操作.例如，让事务处理字段中的输入，而仅调用服务器来验证数据.

You could do this but it would involve a lot of traffic and needless comunication.
The big problem is you''ll need to handle the events client side to pass them through to the server.
A better approach would be to decide at what atomic level you should be communicating client action. For example, let the cleint deal with input into fields and only call the server for validation of data.
