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.

TypeScript

function initMap(): void {
  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!");
  });
}

JavaScript

function initMap() {
  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!");
  });
}

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;
}
