Getting Lat/Lng from a Click Event

Stay organized with collections Save and categorize content based on your preferences.

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

async function initMap() {
  // Request needed libraries.
  const { Map } = await google.maps.importLibrary("maps") as google.maps.MapsLibrary;

  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);
  });
}

initMap();

Note: Read the guide on using TypeScript and Google Maps. JavaScript

async function initMap() {
  // Request needed libraries.
  const { Map } = await google.maps.importLibrary("maps");
  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);
  });
}

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;
}
