Map.addMarker Function

Format

markerId = map_name.addMarker(latitude, longitude);

Description

The Map.addMarker function creates a new marker at the position defined by latitude and longitude and adds the new marker to the Map object named map_name. Initially the marker will have the default red and black marker icon and no description.

You can customize the marker icon using the function Map.setMarkerText or Map.setMarkerImage. You can add a description of the marker using Map.setMarkerDescription. The description will appear in the marker list and in a popup when the user taps on the marker.

Return Value

The function returns the identifier of the new marker which may be used in subsequent calls to Map.removeMarker, Map.setMarkerText, Map.setMarkerImage, Map.setMarkerDescription Map.setMarkerOnClick, Map.setMarkerOnClickInfoWindow, Map.setMarkerOnDrag, Map.setMarkerLocation, Map.getMarkerLatitude, or Map.getMarkerLongitude.
