Question

我有这些 kml 文本，我想将所有“项目”数据显示到谷歌地图信息窗口中。

Javascript：

function showInContentWindow(kmlEvent) {
                var desc = kmlEvent.featureData;
                var content = "<div>" + kmlEvent.featureData.PROJECT + "</div>";
                infowindow.setPosition(kmlEvent.latLng);
                infowindow.setOptions({
                  pixelOffset: kmlEvent.pixelOffset,
                  content: content
                });
                infowindow.open(map);
              }

当我单击多边形时，它总是显示“未定义”我已经尝试过：kmlEvent.featureData.description（结果相同）

如何在信息窗口中显示“项目”和其他值？任何人都可以帮忙吗？谢谢
