Question

I want to get a new map not using refush the webpage.

thanks

and has easy way to get all Overlays on the map?

Answer 1

Look the google map api documentation

And in particular: clearOverlays()

Answer 2

In the v2 API, there was the clearOverlays() method as Gaby pointed out. However, this method is not present if the v3 API. If I remember correctly, this omission was intentional to keep the library lightweight.

Therefore, with the v3 API, you have to keep a reference of your overlays, and then call setMap(null) on each overlay.
