Google Maps API ve GeoJSON

Question

GeoJSON ve Google Maps API ile ilgili bir sorun yaşıyorum. Ben ile MultiLineString ...
1) Her satır sahip O kendi renk ve
2) çizmek nasıl
Her satır sahip bu kendi özellikleri ve
3) Her satırda tıklanabilir olmalı ve öyle içeren bir bilgi penceresi göstermelidir özellikleri

Numuneler JavaScript: kullanıcı yüklemek veya haritada anahtarlarını boşaltmaya gibi

var dataGEOJSON=[]; 
function LoadMyGEOJSON(key) 
{ 
    dataGEOJSON[key] = new google.maps.Data(); 
    dataGEOJSON[key].loadGeoJson('GetLatLngGEOJSON.aspx?key=' + key); 
    dataGEOJSON[key].setMap(map); 
} 

dizinin nedeni, onlar yüklenen tuşları takip edebilirsiniz öbür tarafta t varis kullanıcı arayüzü.

Numune GeoJSON:

Bu benim GeoJSON'a kullanıyorum ilk defa, bu yüzden özellikleri ve stilleri eklemek için gerekli GeoJSON formatı ile yardıma ihtiyaç olacaktır. Ayrıca javascript ve Google Map API kodu. Herhangi biri detaylı örnekler veren bazı kaynaklara bir kod veya bağlantı sağlayabilirse, bu büyük bir memnuniyetle karşılanacaktır.

Answer 1

Bir seçenek, GeoJSON'u yüklenirken işlenerek, satırın her bölümünden google.maps.Polyline nesnesi oluşturulur. Çoklu çizgi segmentinin ilk noktasına InfoWindow konumunu ayarlamak, (gibi this question cevap olarak markörler için kullanılan fonksiyon kapatma kullanarak
