MapElement class
google.maps.MapElement
class
MapElement is an HTMLElement
subclass for rendering maps. After loading the maps
library, a map can be created in HTML. For example:
<gmp-map center="37.4220656,-122.0840897" zoom="10" map-id="DEMO_MAP_ID">
<button slot="control-block-start-inline-end">Custom Control</button>
</gmp-map>
Internally, it uses
Map
, which can be accessed with the MapElement.innerMap
property.
Custom element:
<gmp-map center="lat,lng" heading-interaction-disabled internal-usage-attribution-ids="id1 id2" map-id="string" rendering-type="vector" tilt-interaction-disabled zoom="number"></gmp-map>
This class extends
HTMLElement
.
This class implements
MapElementOptions
.
Access by calling const {MapElement} = await google.maps.importLibrary("maps")
.
See Libraries in the Maps JavaScript API.

MapElement |
MapElement([options]) Parameters:
|
Properties | |
---|---|
center |
Type:
LatLng|LatLngLiteral optional The center latitude/longitude of the map.
HTML attribute:
|
headingInteractionDisabled |
Type:
boolean optional Default:
false Whether the map should allow user control of the camera heading (rotation). This option is only in effect when the map is a vector map. If not set in code, then the cloud configuration for the map ID will be used (if available).
HTML attribute:
|
innerMap |
Type:
Map A reference to the Map that the MapElement uses internally. |
internalUsageAttributionIds |
Type:
Iterable<string> optional Default:
null Adds a usage attribution ID to the initializer, which helps Google understand which libraries and samples are helpful to developers, such as usage of a marker clustering library. To opt out of sending the usage attribution ID, it is safe to delete this property or replace the value with an empty string. Only unique values will be sent. Changes to this value after instantiation may be ignored.
HTML attribute:
|
mapId |
Type:
string optional The map ID of the map. This parameter cannot be set or changed after a map is instantiated.
Map.DEMO_MAP_ID can be used to try out features that require a map ID but which do not require cloud enablement.HTML attribute:
|
renderingType |
Type:
RenderingType optional Default:
RenderingType.VECTOR Whether the map should be a raster or vector map. This parameter cannot be set or changed after a map is instantiated. If not set, then the cloud configuration for the map ID will determine the rendering type (if available). Please note that vector maps may not be available for all devices and browsers and the map will fall back to a raster map as needed.
HTML attribute:
|
tiltInteractionDisabled |
Type:
boolean optional Default:
false Whether the map should allow user control of the camera tilt. This option is only in effect when the map is a vector map. If not set in code, then the cloud configuration for the map ID will be used (if available).
HTML attribute:
|
zoom |
Type:
number optional The zoom level of the map. Valid zoom values are numbers from zero up to the supported maximum zoom level. Larger zoom values correspond to a higher resolution.

Constructor | |
---|---|
Map |
Map(mapDiv[, opts]) Parameters:
Creates a new map inside of the given HTML container, which is typically a DIV element. |
Constants | |
---|---|
DEMO_MAP_ID |
Map ID which can be used for code samples which require a map ID. This map ID is not intended for use in production applications and cannot be used for features which require cloud configuration (such as Cloud Styling). |
Properties | |
---|---|
controls |
Type:
Array<MVCArray<HTMLElement>> Additional controls to attach to the map. To add a control to the map, add the control's <div> to the MVCArray corresponding to the ControlPosition where it should be rendered. |
data |
Type:

mapTypes |
Type:
MapTypeRegistry A registry of MapType instances by string ID. |
overlayMapTypes |
Additional map types to overlay. Overlay map types will display on top of the base map they are attached to, in the order in which they appear in the overlayMapTypes array (overlays with higher index values are displayed in front of overlays with lower index values). |
Methods | |
---|---|
fitBounds |
fitBounds(bounds[, padding]) Parameters:
Return Value: None
Sets the viewport to contain the given bounds. Note: When the map is set to display: none , the fitBounds function reads the map's size as 0x0, and therefore does not do anything. To change the viewport while the map is hidden, set the map to visibility: hidden , thereby ensuring the map div has an actual size. For vector maps, this method sets the map's tilt and heading to their default zero values. Calling this method may cause a smooth animation as the map pans and zooms to fit the bounds. Whether or not this method animates depends on an internal heuristic. |
getBounds |
getBounds() Parameters: None
Return Value:
LatLngBounds|undefined The lat/lng bounds of the current viewport.Returns the lat/lng bounds of the current viewport. If more than one copy of the world is visible, the bounds range in longitude from -180 to 180 degrees inclusive. If the map is not yet initialized or center and zoom have not been set then the result is undefined . For vector maps with non-zero tilt or heading, the returned lat/lng bounds represents the smallest bounding box that includes the visible region of the map's viewport. See MapCanvasProjection.getVisibleRegion for getting the exact visible region of the map's viewport. |
getCenter |
getCenter() Parameters: None
Return Value:
LatLng|undefined |
getClickableIcons |
getClickableIcons() Parameters: None
Return Value:
boolean|undefined Returns the clickability of the map icons. A map icon represents a point of interest, also known as a POI. If the returned value is true , then the icons are clickable on the map. |
|
getDatasetFeatureLayer(datasetId) Parameters:
Return Value:
FeatureLayer Returns the FeatureLayer for the specified datasetId . Dataset IDs must be configured in the Google Cloud Console. If the dataset ID is not associated with the map's map style, or if Data-driven styling is not available (no map ID, no vector tiles, no Data-Driven Styling feature layers or Datasets configured in the Map Style), this logs an error, and the resulting FeatureLayer.isAvailable will be false. |
getDiv |
getDiv() Parameters: None
Return Value:
HTMLElement The mapDiv of the map. |
getFeatureLayer |
getFeatureLayer(featureType) Parameters:
Return Value:
FeatureLayer Returns the FeatureLayer of the specific FeatureType . A FeatureLayer must be enabled in the Google Cloud Console. If a FeatureLayer of the specified FeatureType does not exist on this map, or if Data-driven styling is not available (no map ID, no vector tiles, and no FeatureLayer enabled in the map style), this logs an error, and the resulting FeatureLayer.isAvailable will be false. |
getHeading |
getHeading() Parameters: None
Return Value:
number|undefined Returns the compass heading of the map. The heading value is measured in degrees (clockwise) from cardinal direction North. If the map is not yet initialized then the result is undefined . |
getHeadingInteractionEnabled |
getHeadingInteractionEnabled() Parameters: None
Return Value:
boolean|null Returns whether heading interactions are enabled. This option is only in effect when the map is a vector map. If not set in code, then the cloud configuration for the map ID will be used (if available). |
getInternalUsageAttributionIds |
getInternalUsageAttributionIds() Parameters: None
Return Value:
Iterable<string>|null Returns the list of usage attribution IDs, which help Google understand which libraries and samples are helpful to developers, such as usage of a marker clustering library. |
getMapCapabilities |
getMapCapabilities() Parameters: None
Return Value:
MapCapabilities Informs the caller of the current capabilities available to the map based on the map ID that was provided. |
getMapTypeId |
getMapTypeId() Parameters: None
Return Value:
MapTypeId|string|undefined |
getProjection |
getProjection() Parameters: None
Return Value:
Projection|undefined Returns the current Projection . If the map is not yet initialized then the result is undefined . Listen to the projection_changed event and check its value to ensure it is not undefined . |
getRenderingType |
getRenderingType() Parameters: None
Return Value:
RenderingType Returns the current RenderingType of the map. |
getStreetView |
getStreetView() Parameters: None
Return Value:
StreetViewPanorama The panorama bound to the map.Returns the default StreetViewPanorama bound to the map, which may be a default panorama embedded within the map, or the panorama set using setStreetView() . Changes to the map's streetViewControl will be reflected in the display of such a bound panorama. |
getTilt |
getTilt() Parameters: None
Return Value:
number|undefined Returns the current angle of incidence of the map, in degrees from the viewport plane to the map plane. For raster maps, the result will be 0 for imagery taken directly overhead or 45 for 45° imagery. This method does not return the value set by setTilt . See setTilt for details. |
getTiltInteractionEnabled |
getTiltInteractionEnabled() Parameters: None
Return Value:
boolean|null Returns whether tilt interactions are enabled. This option is only in effect when the map is a vector map. If not set in code, then the cloud configuration for the map ID will be used (if available). |
getZoom |
getZoom() Parameters: None
Return Value:
number|undefined Returns the zoom of the map. If the zoom has not been set then the result is undefined . |
moveCamera |
moveCamera(cameraOptions) Parameters:
Return Value: None
Immediately sets the map's camera to the target camera options, without animation. |
panBy |
panBy(x, y) Parameters:
Return Value: None
Changes the center of the map by the given distance in pixels. If the distance is less than both the width and height of the map, the transition will be smoothly animated. Note that the map coordinate system increases from west to east (for x values) and north to south (for y values). |
panTo |
panTo(latLng) Parameters:
Return Value: None
Changes the center of the map to the given LatLng . If the change is less than both the width and height of the map, the transition will be smoothly animated. |
panToBounds |
panToBounds(latLngBounds[, padding]) Parameters:
Return Value: None
Pans the map by the minimum amount necessary to contain the given LatLngBounds . It makes no guarantee where on the map the bounds will be, except that the map will be panned to show as much of the bounds as possible inside {currentMapSizeInPx} - {padding} . For both raster and vector maps, the map's zoom, tilt, and heading will not be changed. |
setCenter |
setCenter(latlng) Parameters:
Return Value: None
|
setClickableIcons |
setClickableIcons(value) Parameters:
Return Value: None
Controls whether the map icons are clickable or not. A map icon represents a point of interest, also known as a POI. To disable the clickability of map icons, pass a value of false to this method. |
