如何从GGeoXml对象获取KML数据(How to get the KML data from a GGeoXml object)

如何从GGeoXml对象获取KML数据(How to get the KML data from a GGeoXml object)

我使用以下代码将KML文件加载到Google地图对象中：

map = new GMap2(document.getElementById("map_canvas")); geoXml = new GGeoXml(kml); GEvent.addListener(geoXml, "load", function() { geoXml.gotoDefaultViewport(map); // I would like to read the KML contents here }); map.addOverlay(geoXml); // ...

我想从KML文件中读取地标并将它们显示在列表中。 我知道我需要的信息正在传输到浏览器，但我不知道如何访问它。

I load an KML file into a google map object using the following code:

map = new GMap2(document.getElementById("map_canvas")); geoXml = new GGeoXml(kml); GEvent.addListener(geoXml, "load", function() { geoXml.gotoDefaultViewport(map); // I would like to read the KML contents here }); map.addOverlay(geoXml); // ...

I would like to read the placemarks from the KML file and display them in a list. I know that the information I need is being transferred to the browser but I don't know how to access it.

您无法通过API访问它，但数据在GGeoXML对象内的混淆属性中可用。 在Firebug中查看它，我在这里找到了这些信息：geoxml。$ q.ia。 自己查看一下，看看你需要的属性（名称，描述等）。

You can't access it through the API, but the data is available in obfuscated properties inside GGeoXML object. Looking at it in Firebug, I found that information here: geoxml.$q.ia. Look at it yourself to see the properties you need (name, description, etc.).
