javascript - google.maps.places is undefined

Question

I have a website that loads 3 seperate "views" of a location via Google Maps, Street and Places.

Please see my code below:

I have finally gotten Maps and Street view to work properly but am struggling a bit with this one.

I have a tab that displays the same as map but with places added.

<script type="text/javascript" 
  src="http://maps.googleapis.com/maps/api/js?v=3&key=....&sensor=false&callback=initializeMap"></script>

<script type="text/javascript">
var myLattitude = <?php echo $data["lattitude"]; ?>;
var myLongitude = <?php echo $data["longitude"]; ?>;
var poiMap;
var infowindow;

function initializePoi() {
            var poiCentre = new google.maps.LatLng(myLattitude, myLongitude);

            poiMap = new google.maps.Map(document.getElementById('poi-canvas'), {
                center: poiCentre,
                zoom: 15
            });

            var request = {
                location: poiCentre,
                radius: 500,
                types: ['store']
            };
            infowindow = new google.maps.InfoWindow();
            var service = new google.maps.places.PlacesService(poiMap);
            service.nearbySearch(request, callback);
        }

        function callback(results, status) {
            if (status == google.maps.places.PlacesServiceStatus.OK) {
                for (var i = 0; i < results.length; i++) {
                    createMarker(results[i]);
                }
            }
        }

        function createMarker(place) {
            var placeLoc = place.geometry.location;
            var marker = new google.maps.Marker({
                map: poiMap,
                position: place.geometry.location
            });

            google.maps.event.addListener(marker, 'click', function() {
                infowindow.setContent(place.name);
                infowindow.open(poiMap, this);
            });
        }

Now This initializes properly but the console throws the following error: TypeError: google.maps.places is undefined

I just want to know why I get this error, I like having clean errorless code.

The places do actually show up properly and everything.

You should add the option libraries=places in the Google API URL

In your case you should replace the following:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3&key=....&sensor=false&callback=initializeMap"></script>

With this:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3&key=....&sensor=false&callback=initializeMap&libraries=places"></script>

Look at the end of the src=""
