This example demonstrates the use of event listeners. It
- listens for the
clickevent on a marker to zoom the map when the marker is clicked. - listens for the
center_changedevent to pan the map back to the marker after 3 seconds.
Read the documentation.
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;
}
