Is there a way to use the \"My location\" button that exist on Google Maps in your own webbapplication using the javascript api?
I have read about adding controls here Googl
There's currently no geolocation button in Google Maps API v3. But it's not difficult to implement one yourself.
Information about implementing geolocation can be found in the Google Maps Javascript API documentation.
If you want to add a geolocation button as a map control, read the Custom Controls section of the Google Maps documentation.
