Google Maps API

The Google Maps API is now integrated with the Google AJAX API loader, which creates a common namespace for
loading and using multiple Google AJAX APIs. This framework allows you to use the optional google.maps.*
namespace for all classes, methods and properties you currently use in the Google Maps API, replacing the normal
G prefix with this namespace. Don't worry: the existing G namespace will continue to be supported.
For example, the GMap2 object within the Google Maps API can also be defined as google.maps.Map2.
Note that this reference documentation refers only to the existing G namespace.
If you only want to use the map to display your content, then you need to know these classes, types, and functions:
GMap2
GMapOptions
GGoogleBarOptions
GInfoWindow
GInfoWindowTab
GInfoWindowOptions
GMarker
GMarkerOptions
GPolyline

GPolyEditingOptions

GStreetviewPanorama

GStreetviewClient

GStreetviewData
GStreetviewLocation
GStreetviewLink

If you want to extend the functionality of the maps API by implementing your own controls, overlays, or map types, then
you also need to know these classes and types:
GGoogleBarListingTypes
GGoogleBarLinkTarget
GGoogleBarResultList
GControlAnchor
GMapTypeControl
GMenuMapTypeControl
GTileLayerOverlay
GCopyrightCollection
GCopyright

enableGoogleBar() none Enables the GoogleBar, an integrated search

control, to the map. When enabled, this control

takes the place of the default Powered By

Google logo. Note that this control is not

enabled by default. (Since 2.92)

disableGoogleBar() none Disables the GoogleBar integrated search

control. When disabled, the default Powered by

Google logo occupies the position formerly

containing this control. Note that this control is

already disabled by default. (Since 2.92)

enableScrollWheelZoom() none Enables zooming using a mouse's scroll wheel.

Note: scroll wheel zoom is disabled by default.

(Since 2.78)

disableScrollWheelZoom() none Disables zooming using a mouse's scroll wheel.

Note: scroll wheel zoom is disabled by default.

(Since 2.78)

scrollWheelZoomEnabled() Boolean Returns a Boolean indicating whether scroll

wheel zooming is enabled. (Since 2.78)

Methods Return

Value

Description

addControl(control,

position?)

none Adds the control to the map. The position on the map

is determined by the optional position argument. If

this argument is absent, the default position of the

control is used, as determined by the

GControl.getDefaultPosition() method. A

control instance must not be added more than once to

the map.

removeControl(control) none Removes the control from the map. It does nothing if

the control was never added to the map.

getContainer() Node Returns the DOM object that contains the map. Used

by GControl.initialize().

Methods Return

Value

Description

getMapTypes() Array of

GMapType

Returns the array of map types registered with this

map.

getCurrentMapType() GMapType Returns the currently selected map type.

setMapType(type) none Selects the given new map type. The type must be

known to the map. See the constructor, and the

method addMapType().

addMapType(type) none Adds a new map type to the map. See section

GMapType for how to define custom map types.

removeMapType(type) none Removes the map type from the map. Will update the

set of buttons displayed by the GMapTypeControl

or GHierarchicalMapTypeControl and fire

or GHierarchicalMapTypeControl and fire

the removemaptype event.

Methods Return Value Description

isLoaded() Boolean

Returns true iff the map was initialized by

setCenter() since it was created.

getCenter() GLatLng Returns the geographical coordinates of the center

point of the map view.

getBounds() GLatLngBounds Returns the the visible rectangular region of the map

view in geographical coordinates.

getBoundsZoomLevel(bounds) Number Returns the zoom level at which the given rectangular

region fits in the map view. The zoom level is

computed for the currently selected map type. If no

map type is selected yet, the first on the list of map

types is used.

getSize() GSize Returns the size of the map view in pixels.

getZoom() Number Returns the current zoom level.

getDragObject() GDraggableObject Returns the draggable object used by this map. (Since

2.93)

getEarthInstance(callback) none Retrieves the instance of the Google Earth Browser

Plugin attached to this map, and calls the passed

callback function once the instance is ready to receive

commands, passing the earth instance (a GEPlugin

object) as a parameter. This callback function may fire

immediately if the Earth instance had previously been

instantiated by setting the Google Earth map type via

GMap2.setMapType(G_SATELLITE_3D_MAP).

If the instance if not yet created, calling

getEarthInstance will initialize the Google Earth

Plug-in. (This asynchronous behavior is why this

method requires a callback.) Note: if the initialization

encounters an error, the callback function will pass a

null parameter. Note that that while this method will

create an Earth instance, it will not set the Earth map

type as the current view. To so so, call

GMap2.setMapType(G_SATELLITE_3D_MAP)

explicitly, or allow the user to select this map type via

the MapTypeControl. See the Google Earth API

Developer's Guide for details on how to use the

GEPlugin object. (Since 2.113)

Methods Return

Value

Description

setCenter(center,

zoom?, type?)

none Sets the map view to the given center. Optionally,

also sets zoom level and map type. The map type

must be known to the map. See the constructor, and

the method addMapType(). This method must be

called first after construction to set the initial state of

the map. It is an error to call operations on a newly

Map State
