Page Summary
This example demonstrates how to listen for DOM events on a Google Map.
When a user clicks on the map's div container, an alert message is triggered.
The sample provides code in TypeScript and JavaScript showcasing DOM event handling.
CSS is used to ensure the map div element occupies the full height of the page for better visibility.
This example listens for DOM events. It displays an alert when the DIVcontaining the map is clicked.

TypeScript
asyncfunctioninitMap(){// Request needed libraries.const{Map}=awaitgoogle.maps.importLibrary("maps")asgoogle.maps.MapsLibrary;constmapDiv=document.getElementById("map")asHTMLElement;constmap=newgoogle.maps.Map(mapDiv,{zoom:8,center:newgoogle.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!");});}initMap();
JavaScript
asyncfunctioninitMap(){// Request needed libraries.const{Map}=awaitgoogle.maps.importLibrary("maps");constmapDiv=document.getElementById("map");constmap=newgoogle.maps.Map(mapDiv,{zoom:8,center:newgoogle.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!");});}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;}
