How to write the code of ASP website to realize praise function

Tell me about the principle, for example, you should add a praise function to the article.

add a field to the article list for praise.

Then add a button to the article page, like it, and ASP will handle it. Just add 1 to the article like field of this ID. . .

simple implementation <; %' database, read out the article %>

< %=rs ("article content, etc.") %>

< a? href="like.asp? id=< %=rs ("the article ID read above")% > " > Like <; /a>

like.asp

< % database connected with

id=request("id")

update? table? set? Like field = like field +1? where? id="& Id

judgment success/error

If no refresh is needed, then cooperate with JS? AJAX can do it.
