How to Create InfoWindows for Multiple Markers in a For loop

Question

Answer 1

You need to create the markers in a separate function:

   // Global var
   var infowindow = new google.maps.InfoWindow();

and then, inside the loop:

    var markerLatlng = new google.maps.LatLng(Lat, Lng);
    var title = {{record.title|json_encode|safe}}
    var iwContent = {{record.description|json_encode|safe}}
    createMarker(markerLatlng ,title,iwContent);

Finally:

    function createMarker(latlon,title,iwContent) {
      var marker = new google.maps.Marker({
          position: latlon,
          title: title,
          map: map
    });


google.maps.event.addListener(marker, 'click', function () {
    infowindow.setContent(iwContent);
    infowindow.open(map, marker);
    });

    }
