Data Layer: Event Handling

Read the documentation or view this example full screen.

var map;
function initMap() {
  map = new google.maps.Map(document.getElementById('map'), {
    zoom: 4,
    center: {lat: -28, lng: 137}
  });

  // Load GeoJSON.
  map.data.loadGeoJson('https://storage.googleapis.com/maps-devrel/google.json');

  // Add some style.
  map.data.setStyle(function(feature) {
    return /** @type {google.maps.Data.StyleOptions} */({
      fillColor: feature.getProperty('color'),
      strokeWeight: 1
    });
  });

  // Set mouseover event for each feature.
  map.data.addListener('mouseover', function(event) {
    document.getElementById('info-box').textContent =
        event.feature.getProperty('letter');
  });
}
<div id="map"></div>
<div id="info-box">?</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;
}
#info-box {
  background-color: white;
  border: 1px solid black;
  bottom: 30px;
  height: 20px;
  padding: 10px;
  position: absolute;
  left: 30px;
}
 <!-- Replace the value of the key parameter with your own API key. -->
