我想在点击第一个控件，第二个文件夹=第二个控件时只显示1个文件夹中的地标。第二个问题，google api仅适用于样式，当它们位于文件夹标签外
我的KML看起来像
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
<Document>
<Folder id="Fusiontables1">

这个js显示所有地标，但我只需要一个
kmlLayer = new google.maps.KmlLayer(kmlUrl, {
preserveViewport: true,
suppressInfoWindows: false
});
UPD。 geoxml库解决了这个问题
