我使用 Google API 来绘制标记和多边形。这很好用，但我似乎无法让多边形的 fillOpacity 和 strokeOpacity 工作。它在设置为 0 或 1 时有效，这让我相信存在某种解析错误。（我在下面的代码中省略了细节，只是用示例替换了它）

  <script type="text/javascript">
var locations = [
  ['EXAMPLETEXT, EXAMPLECOORDINATE1, EXAMPLECOORDINATE2, 1],
];

var limburgcoordinaten = [
    new google.maps.LatLng(EXAMPLECOORDINATE1, EXAMPLECOORDINATE2),
    new google.maps.LatLng(EXAMPLECOORDINATE1, EXAMPLECOORDINATE2),
];

var map = new google.maps.Map(document.getElementById('map'), {
  zoom: 8,
  center: new google.maps.LatLng(EXAMPLECOORDINATE1, EXAMPLECOORDINATE2),
  mapTypeId: google.maps.MapTypeId.ROADMAP
});


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

var marker, i;

for (i = 0; i < locations.length; i++) {  
  marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i][1], locations[i][2]),
    map: map
  });

  google.maps.event.addListener(marker, 'click', (function(marker, i) {
    return function() {
      infowindow.setContent(locations[i][0]);
      infowindow.open(map, marker);
    }
  })(marker, i));

var limburg = new google.maps.Polygon({
    paths: limburgcoordinaten,
    strokeColor: "#FF0000",
    strokeOpacity: 0.7,
    strokeWeight: 2,
    fillColor: "#FF0000",
    fillOpacity: 0.3,
    map: map
});
}

我希望我只是在看一些非常明显的东西！
