For most use cases, set closeOnClick and closeButton to false .

Example

1var markerHeight = 50, markerRadius = 10, linearOffset = 25;
2var popupOffsets = {
3 'top': [0, 0],

15  .setMaxWidth("300px")
16  .addTo(map);

A NavigationControl control contains zoom buttons and a compass.

Constructor

Name
NavigationControl

new NavigationControl(options: NavigationOptions)


Parameters


  1. options: NavigationOptions

Methods

Method
onAdd

onAdd(map: Map)


Parameters


  1. map: Map

Return Value: HTMLElement


Register a control on the map and give it a chance to register event listeners
and resources. This method is called by Map#addControl
internally.
onRemove

onRemove()



Return Value: void


Unregister a control on the map and give it a chance to detach event listeners
and resources. This method is called by Map#removeControl
internally.

Example

1var nav = new nextbillion.maps.NavigationControl();
2map.addControl(nav, 'top-left');

GeolocateControl

A GeolocateControl control provides a button that uses the browser's geolocation
API to locate the user on the map.

Not all browsers support geolocation,
and some users may disable the feature. Geolocation support for modern
browsers including Chrome requires sites to be served over HTTPS. If
geolocation support is not available, the GeolocateControl will show
as disabled.

The zoom level applied will depend on the accuracy of the geolocation provided by the device.

The GeolocateControl has two modes. If trackUserLocation is false (default) the control acts as a button, which when pressed will set the map's camera to target the user location. If the user moves, the map won't update. This is most suited for the desktop. If trackUserLocation is true the control acts as a toggle button that when active the user's location is actively monitored for changes. In this mode the GeolocateControl has three interaction states:
* active - the map's camera automatically updates as the user's location changes, keeping the location dot in the center. Initial state and upon clicking the GeolocateControl button.
* passive - the user's location dot automatically updates, but the map's camera does not. Occurs upon the user initiating a map movement.
* disabled - occurs if Geolocation is not available, disabled or denied.

These interaction states can't be controlled programmatically, rather they are set based on user interactions.
