我有mapquest API的地图,我也使用Leaflet显示邮政编码,L.divIcon位于多边形的中心,显示Zip代码。一切都很好,除了我必须手动输入多边形的中心作为在javascript中显示divIcon的地方。
我想知道的是,是否有办法从javascript读取kml以获得多边形的中心。我可以使用Qgis计算中心并将其保存到kml谎言:
........
<Placemark>
<name>77029</name>
<ExtendedData><SchemaData schemaUrl="#center_jacinto">
<SimpleData name="Descriptio">Jacinto City</SimpleData>
</SchemaData></ExtendedData>
//This is the data I want to read from javascript if I can->
<Point><coordinates>-95.262889587410186,29.761518060337306</coordinates>
</Point>
.....
kml将绘制一个我不想要的标记,我只想要lat和lon,然后我将绘制我的图标..
编辑:我添加了这个但是什么都没有,javascript和html非常新,所以我确定顺序错了

shramov KML plugin不支持读取SimpleData属性。您可能希望使用leaflet-omnivore,因为它确实如此。

似乎有一个拉动请求允许Sharmov KML插件支持ExtendedData等等。
