Hi Jianming!
I don't understand your problem. When users click on a link, a new page
appears. So, what is the problem?
Perhaps you want to say that users click a second time after the request
has got to the server (and the DB updated), but before the response gets
to them. In this case, you'd want to ignore the second request.
This then should be easy: if you find the data already updated in the
DB, then do nothing.
Un saludo,
Alex.
