Accessing arguments in UI events

Read the documentation or view this example full screen.

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 4,
    center: {lat: -25.363882, lng: 131.044922 }
  });

  map.addListener('click', function(e) {
    placeMarkerAndPanTo(e.latLng, map);
  });
}

function placeMarkerAndPanTo(latLng, map) {
  var marker = new google.maps.Marker({
    position: latLng,
    map: map
  });
  map.panTo(latLng);
}
<div id="map"></div>
html, body {
  height: 100%;
  margin: 0;
  padding: 0;
}
#map {
  height: 100%;
}
<!-- Replace the value of the key parameter with your own API key. -->
