This example listens for DOM events. It displays an alert when the DIV containing the map is clicked.
Read the documentation.
TypeScript
function initMap(): void { const mapDiv = document.getElementById("map") as HTMLElement; const map = new google.maps.Map(mapDiv, { zoom: 8, center: new google.maps.LatLng(-34.397, 150.644), }); // We add a DOM event here to show an alert if the DIV containing the // map is clicked. google.maps.event.addDomListener(mapDiv, "click", () => { window.alert("Map was clicked!"); }); }
JavaScript
function initMap() { const mapDiv = document.getElementById("map"); const map = new google.maps.Map(mapDiv, { zoom: 8, center: new google.maps.LatLng(-34.397, 150.644), }); // We add a DOM event here to show an alert if the DIV containing the // map is clicked. google.maps.event.addDomListener(mapDiv, "click", () => { window.alert("Map was clicked!"); }); }
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; }
