Getting Lat/Lng from Google marker

I made a Google Maps map with a draggable marker. When the user drags the marker, I need to know the new latitude and longitude, but I don't understand what is the best approach to doing that.

How can I retrieve the new coordinates?


Here is the JSFiddle Demo. In Google Maps API V3 it's pretty simple to track the lat and lng of a draggable marker. Let's start with the following HTML and CSS as our base.

<div id='map_canvas'></div>
<div id="current">Nothing yet...</div>

    width: 400px;
    height: 300px;

     padding-top: 25px;

Here is our initial JavaScript initializing the google map. We create a marker that we want to drag and set it's draggable property to true. Of course keep in mind it should be attached to an onload event of your window for it to be loaded, but i'll skip to the code:

var map = new google.maps.Map(document.getElementById('map_canvas'), {
    zoom: 1,
    center: new google.maps.LatLng(35.137879, -82.836914),
    mapTypeId: google.maps.MapTypeId.ROADMAP

var myMarker = new google.maps.Marker({
    position: new google.maps.LatLng(47.651968, 9.478485),
    draggable: true

Here we attach two events dragstart to track the start of dragging and dragend to drack when the marker stop getting dragged, and the way we attach it is to use google.maps.event.addListener. What we are doing here is setting the div current's content when marker is getting dragged and then set the marker's lat and lng when drag stops. Google mouse event has a property name 'latlng' that returns 'google.maps.LatLng' object when the event triggers. So, what we are doing here is basically using the identifier for this listener that gets returned by the google.maps.event.addListener and get the property latLng to extract the dragend's current position. Once we get that Lat Lng when the drag stops we'll display within your current div:

google.maps.event.addListener(myMarker, 'dragend', function(evt){
    document.getElementById('current').innerHTML = '<p>Marker dropped: Current Lat: ' + + ' Current Lng: ' + evt.latLng.lng().toFixed(3) + '</p>';

google.maps.event.addListener(myMarker, 'dragstart', function(evt){
    document.getElementById('current').innerHTML = '<p>Currently dragging marker...</p>';

Lastly, we'll center our marker and display it on the map:


Let me know if you have any questions regarding my answer.

You could just call getPosition() on the Marker - have you tried that?

If you're on the deprecated, v2 of the JavaScript API, you can call getLatLng() on GMarker.

try this

var latlng = new google.maps.LatLng(51.4975941, -0.0803232);
var map = new google.maps.Map(document.getElementById('map'), {
    center: latlng,
    zoom: 11,
    mapTypeId: google.maps.MapTypeId.ROADMAP
var marker = new google.maps.Marker({
    position: latlng,
    map: map,
    title: 'Set lat/lon values for this property',
    draggable: true

google.maps.event.addListener(marker, 'dragend', function (event) {
    document.getElementById("latbox").value = this.getPosition().lat();
    document.getElementById("lngbox").value = this.getPosition().lng();

var lat = marker.getPosition().lat();
var lng = marker.getPosition().lng();

More information can be found at Google Maps API - LatLng


// show the marker position //

console.log( );
console.log( objMarker.position.lng() );

// create a new point based into marker position //

var deltaLat = 1.002;
var deltaLng = -1.003;

var objPoint = new google.maps.LatLng( 
  parseFloat( ) + deltaLat, 
  parseFloat( objMarker.position.lng() ) + deltaLng

// now center the map using the new point //

objMap.setCenter( objPoint );


You should add a listener on the marker and listen for the drag or dragend event, and ask the event its position when you receive this event.

See for the description of events triggered by the marker. And see for methods allowing to add event listeners.

There are a lot of answers to this question, which never worked for me (including suggesting getPosition() which doesn't seem to be a method available for markers objects). The only method that worked for me in maps V3 is (simply) :

var lat =;
var long = marker.lng();
