Adding a marker to the map by the user on click, how to do it?

Question

Google

Let me know if anyone saw or did it.
The bottom line is that the user must leave one marker on the map, if he clicked on another place, then the old marker is removed, and a new one is added.
Even I can't find an example anywhere
