This example listens for the click
event, gets the latitude and longitude coordinates
of the click from google.maps.MapMouseEvent.latLng
, and displays those coordinates in
an info window.
Read the documentation.
TypeScript
function initMap() { const myLatlng = { lat: -25.363, lng: 131.044 }; const map = new google.maps.Map(document.getElementById("map")!, { zoom: 4, center: myLatlng, }); // Create the initial InfoWindow. let infoWindow = new google.maps.InfoWindow({ content: "Click the map to get Lat/Lng!", position: myLatlng, }); infoWindow.open(map); // Configure the click listener. map.addListener("click", (mapsMouseEvent) => { // Close the current InfoWindow. infoWindow.close(); // Create a new InfoWindow. infoWindow = new google.maps.InfoWindow({ position: mapsMouseEvent.latLng, }); infoWindow.setContent( JSON.stringify(mapsMouseEvent.latLng.toJSON(), null, 2) ); infoWindow.open(map); }); } declare global { interface Window { initMap: () => void; } } window.initMap = initMap;
JavaScript

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; }
