如何从GGeoXml对象获取KML数据 [英] How to get the KML data from a GGeoXml object

问题描述

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 的））; 
 geoXml = new GGeoXml（kml）; 
 GEvent.addListener（geoXml，load，function（）{
 geoXml.gotoDefaultViewport（map）; 
 //我想在这里阅读KML的内容
}） ; 
 map.addOverlay（geoXml）; 
 // ... 
  

我想要读取KML文件中的地标和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。 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，我发现这里的信息：
geoxml。$ q.ia。看看它自己，看看你需要的属性（名称，描述等）。

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.

解决方案

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.).
