The Places Library does all the work. You only have to send the fields you require and then display Place Details Results
The following code is taken from the documentation to show you where to add to it to implement your preferences.
var map;
var service;
var infowindow;
function initialize() {
var pyrmont = new google.maps.LatLng(-33.8665433,151.1956316);
map = new google.maps.Map(document.getElementById('map'), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: pyrmont,
zoom: 15
});
//Here you add the fields you require for request for PlacesService()
var request = {
location: pyrmont,
radius: '500',
types: ['store']
};
service = new google.maps.places.PlacesService(map);
service.nearbySearch(request, callback);
}
//Here you display the Place Details Results
function callback(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
for (var i = 0; i < results.length; i++) {
var place = results[i];
createMarker(results[i]);
}
}
}
