Listening to DOM events

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

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>
/* 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;
}
 <!-- 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">
</script>
