Accessing Arguments in UI Events

This example creates a map that the user can click to create a marker at theclicked point.

Read thedocumentation.

TypeScript

asyncfunctioninitMap(){// Request needed libraries.const{Map}=awaitgoogle.maps.importLibrary("maps")asgoogle.maps.MapsLibrary;const{AdvancedMarkerElement,PinElement}=awaitgoogle.maps.importLibrary("marker")asgoogle.maps.MarkerLibrary;constmap=newgoogle.maps.Map(document.getElementById("map")asHTMLElement,{zoom:4,center:{lat:-25.363882,lng:131.044922},mapId:"DEMO_MAP_ID",});map.addListener("click",(e)=>{placeMarkerAndPanTo(e.latLng,map);});}functionplaceMarkerAndPanTo(latLng:google.maps.LatLng,map:google.maps.Map){newgoogle.maps.marker.AdvancedMarkerElement({position:latLng,map:map,});map.panTo(latLng);}initMap();
Note: Read theguide on using TypeScript and Google Maps.

JavaScript

asyncfunctioninitMap(){// Request needed libraries.const{Map}=awaitgoogle.maps.importLibrary("maps");const{AdvancedMarkerElement,PinElement}=awaitgoogle.maps.importLibrary("marker",);constmap=newgoogle.maps.Map(document.getElementById("map"),{zoom:4,center:{lat:-25.363882,lng:131.044922},mapId:"DEMO_MAP_ID",});map.addListener("click",(e)=>{placeMarkerAndPanTo(e.latLng,map);});}functionplaceMarkerAndPanTo(latLng,map){newgoogle.maps.marker.AdvancedMarkerElement({position:latLng,map:map,});map.panTo(latLng);}initMap();
Note: The JavaScript is compiled from the TypeScript snippet.

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;}
