如何访问谷歌地图中 kml 层中单击线的坐标

Question

我使用 JS 运行我的谷歌地图，我完美地添加了 kml 层，当我点击线上的某个点时，我需要获取线点击地标的列表，而不仅仅是点击点的经纬度。

这是我试过的：

            var kml_layer = new google.maps.KmlLayer(src, {
                suppressInfoWindows: true,
                preserveViewport: true,
                map: map
            });
            kml_layer.addListener('click', (kmlEvent) => {
  var clickedFeature = kmlEvent.featureData;

    var geometries = clickedFeature.geometry.getGeometries();
    console.log("OOOOOOOO " + geometries);

    for (var i = 0; i < geometries.length; i++) {
      var geometry = geometries[i];

      // Check if the geometry is a LineString
      if (geometry.getType() == 'LineString') {

        // Get the coordinates of the LineString
        var coordinates = geometry.getArray();

        // Do something with the coordinates
        console.log(coordinates);
      }
    }

但是我得到这个错误：

"Uncaught TypeError: Cannot read properties of undefined (reading 'getGeometries')"
