Simple Map

Loading the Maps JavaScript API

The Google Maps API are loaded using a script tag like so:

<script src=""></script>

The libraries parameter is for loading additional libraries for Google Maps. The MapsIndoors SDK has a dependency on the geometry library. The key parameter contains your application’s Google Maps API key. Look here For more information about how to obtain a key.

Loading the MapsIndoors SDK

The MapsIndoors SDK are loaded afther the Google Maps API using a script tag like so:

<script src=""></script>

The apiKey parameter contains your application’s MapsIndoors API key.

Setting up the map

const googleMap = new google.maps.Map(document.getElementById('map'), {
    center: {
        lat: 38.8976067,
        lng: -77.0365872
    zoom: 19,
    maxZoom: 21

First we need a DOM element for the map. document.getElementById('googleMap') Next we will configure the map by setting the center and a zoom level. The maxZoom parameter is set to disable the map from zooming further in that level 21.

Adding MapsIndoors

const mapsIndoors = new mapsindoors.MapsIndoors({
    map: googleMap,

Now we create a new instance of the MapsIndoors class and assign the Google Map to the map parameter.

Adding a floor selector

const floorSelector = document.createElement('div');
new mapsindoors.FloorSelector(floorSelector, mapsIndoors);

A FloorSelector is created by calling the new mapsindoors.FloorSelector(floorSelector, mapsIndoors); passing in a DOM element and an instance of MapsIndoors. This googleMap.controls[google.maps.ControlPosition.RIGHT_TOP].push(floorSelector); adds the floor selector to the maps upper right corner as a map control.
