Listening to DOM events

Read the documentation or view this example full screen.

function initMap() {
  var mapDiv = document.getElementById('map');
  var 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', function() {
    window.alert('Map was clicked!');
  });
}
<div id="map"></div>
html, body {
  height: 100%;
  margin: 0;
  padding: 0;
}
#map {
  height: 100%;
}
<!-- Replace the value of the key parameter with your own API key. -->
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCkUOdZ5y7hMm0yrcCQoCvLwzdM6M8s5qk&callback=initMap">

JavaScript
function initMap() {
  var mapDiv = document.getElementById('map');
  var 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', function() {
    window.alert('Map was clicked!');
