This example demonstrates the use of event listeners. It
- listens for the
click
event on a marker to zoom the map when the marker is clicked. - listens for the
center_changed
event to pan the map back to the marker after 3 seconds.

function initMap() { var myLatlng = {lat: -25.363, lng: 131.044}; var map = new google.maps.Map(document.getElementById('map'), { zoom: 4, center: myLatlng }); var marker = new google.maps.Marker({ position: myLatlng, map: map, title: 'Click to zoom' }); map.addListener('center_changed', function() { // 3 seconds after the center of the map has changed, pan back to the // marker. window.setTimeout(function() { map.panTo(marker.getPosition()); }, 3000); }); marker.addListener('click', function() { map.setZoom(8); map.setCenter(marker.getPosition()); }); }
<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; }
