How to customize results returned in nearby place search, Google Maps JS API V3

I am still relatively new to Google Maps API and JS so this might (probably)
have a simple answer.

I am now returning all places within a certain radius from where my location
is set but I want to be more specific such as only plant nursery's, fuel stations and gyms and only display those markers.

Sorry about the long code block, here is a JSBin if you'd prefer

Thanks in advance.

return;
}
$.each(markers, function() {

if (!closest || closest.distance > distance) {

}
});
if (closest) {

Answer

Its quite simple. You need to pass an array of types that you need to edit your request with a new attribute called types to filter. Ex types: ['bank', 'gym']

Code Block below and I will attached a modified version of your JS Bin

JS Bin

Places types can be find from the links below

Place Types

Google Places API Documentation - developers.google.com/maps/documentation/javascript/places#place_search_requests

var request = {
            location: pos,
            radius: 1000,
            types: ['bank', 'gym']
          };
          infowindow = new google.maps.InfoWindow();
          var service = new google.maps.places.PlacesService(map);
          service.nearbySearch(request, callback);
