TypeScript
function initMap(): void { const map = new google.maps.Map( document.getElementById("map") as HTMLElement, { zoom: 14, center: { lat: 42.3726399, lng: -71.1096528 }, } ); const bikeLayer = new google.maps.BicyclingLayer(); bikeLayer.setMap(map); } declare global { interface Window { initMap: () => void; } } window.initMap = initMap;
JavaScript
function initMap() { const map = new google.maps.Map(document.getElementById("map"), { zoom: 14, center: { lat: 42.3726399, lng: -71.1096528 }, }); const bikeLayer = new google.maps.BicyclingLayer(); bikeLayer.setMap(map); } window.initMap = initMap;
CSS
/* * Always set the map height explicitly to define the size of the div element * that contains the map. */ #map { height: 100%; } /* * Optional: Makes the sample page fill the window. */ html, body { height: 100%; margin: 0; padding: 0; }
HTML
<html> <head> <title>Bicycle Layer</title> <link rel="stylesheet" type="text/css" href="./style.css" /> <script type="module" src="./index.js"></script> </head> <body> <div id="map"></div> <!-- The `defer` attribute causes the script to execute after the full HTML document has been parsed.
