Simple Click Events

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.

Read the documentation.

JavaScript

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());
  });
}

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;
}
