How to add address to a google map on web page?

I am creating a web app. One of the page is designed to show google map of an address traced fro开发者_C百科m database. So after I get langitude and latitude using gencode, I know how to draw the google map, but how do I show an address tag on that map? Any help is appreciated.

You are probably talking about a Marker concept.

Take a look at this article

A couple of other SO folks asked similar questions. These might be helpful: Draggable markers

While this may be OT, if you ever decide to remove a marker, also look at this question

There is also detailed Marker docs available at the usual API docs site
