Ich habe eine Google Maps erstellt, die Daten aus einer CSV-Datei abrufen. Dies scheint gut zu funktionieren, aber wenn ich alle Objekte durchsuche, scheint das InfoWindow nicht zu funktionieren. Ich schätze, das liegt daran, dass die Variable innerhalb einer for-Schleife ist. Ich habe versucht, den Code in die Schleife zu verschieben, aber dieses Ergebnis in der InfoWindow platziert zufällig auf der Karte statt über die angeklickte Markierung. Wie kann ich erreichen, dass infoWindow mit mehreren Markern arbeitet?infoWindow in Google Maps auf mehreren Markierungen

was über diese Linie 'google.maps.event.addListener (Marker, 'klicken', function() {' Ich denke, dass dies inzwischen geändert werden soll, Kann ich nicht auf Marker zugreifen? –
Ja, Sie müssen möglicherweise auf jeden Marker iterieren, indem Sie das Looping für den 'event.addListener' hinzufügen, damit es wie folgt aussieht' google.maps.event.addListener (arrayOfMarkers [i], 'click', function() {' –
