I have implemented a sample using Places Search of Google Maps API. I would like to fetch the number of results I am fetching. New to Google Maps API. How do I achieve this?
JS:
var map;
var infowindow;
function initialize() {
var pyrmont = new google.maps.LatLng(19.107567, 72.8335);
map = new google.maps.Map(document.getElementById('map-canvas'), {
center: pyrmont,
zoom: 15
});
var request = {
location: pyrmont,
radius: 500,
types: ['hospital']
};
infowindow = new google.maps.InfoWindow();
var service = new google.maps.places.PlacesService(map);
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: map,
position: place.geometry.location
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(place.name);
infowindow.open(map, this);
});
}
google.maps.event.addDomListener(window, 'load', initialize);
Replace your callback with this:
function callback(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
// Just count the number of results passed to your callback
var numResults = results.length;
for (var i = 0; i < results.length; i++) {
createMarker(results[i]);
}
}
}
