Question

谷歌mashup的新手。我在我们的网络服务器（http://www.madisonareampo.org/maps/BRT_National.kmz）上有一个KML，可以在谷歌地图上绘制。

我有一个Google Maps mashup，我希望infowindow通过点击事件显示KML描述字段的内容。使用ArcGIS从地理数据库导出KML文件。

单击KML文件中的标记时，没有返回任何内容。

InfoWindows需要position属性，您必须调用open(map)将其绑定到地图。这是您的代码的工作版本：

google.maps.event.addListener(layer, 'click', function(kmlEvent) {
  showInContentWindow(kmlEvent.latLng, kmlEvent.featureData.description);
});

function showInContentWindow(position, text) {
  var content = "<div style='margin-left:-20px;border:2px dotted #897823;'>" + text +  "</div>";
  var infowindow = new google.maps.InfoWindow({
    content: content, 
    position: position
  })
  infowindow.open(map);
}

从KML获取infowindow描述的问题
