推荐答案

我认为您不理解网站会发生什么.

当用户按下按钮时，在服务器上引发click事件，并运行click处理程序.除非您专门与客户交谈，否则在单击处理程序例程完成之前，其UI不会发生任何更改.因此，就客户端而言，禁用按钮，运行时间密集的代码以及重新启用按钮均无济于事.
如果要禁用客户端按钮，则可能需要考虑使用javascript来实现.

I take you you don''t understand what happens with websites then.

When your user presses a button, the click event is raised at the server, and the click handler is run. Unless you specifically talk to the client, no changes will happen to his UI until the click handler routine is completed. So disabling the button, running time intensive code, and re-enabling the button does nothing as far as the client is concerned.
If you want to disable the client button, then you may want to look at using javascript to do it.
