n this short code snippet article I will explain how to get the Geographical position coordinates of a location i.e. Latitude and Longitude when user clicks anywhere on Google Maps using the Google Maps V3 OnClick event handler.

In the below Google Map implementation, I have assigned an event handler to the Google Map within which the geographical position coordinates of a location i.e. Latitude and Longitude are captured and displayed using JavaScript alert message box.

<body>
    <script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
    <script type="text/javascript">
        window.onload = function () {
            var mapOptions = {
                center: new google.maps.LatLng(18.9300, 72.8200),
                zoom: 14,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            };
            var infoWindow = new google.maps.InfoWindow();
            var latlngbounds = new google.maps.LatLngBounds();
            var map = new google.maps.Map(document.getElementById("dvMap"), mapOptions);
            google.maps.event.addListener(map, 'click', function (e) {
                alert("Latitude: " + e.latLng.lat() + "rnLongitude: " + e.latLng.lng());
            });
        }
    </script>
    <div id="dvMap" style="width: 500px; height: 500px">
    </div>
</body>
