Listening to DOM Events | Maps JavaScript API

Listening to DOM Events

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

This example listens for DOM events. It displays an alert when the DIV containing the map is clicked.

Read the documentation.

TypeScript

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

  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!");
  });
}

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 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!");
  });
}

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;
}
