我使用geoxml3來解析我的kml文件。 這個工作到目前爲止。羣集kml文件與geoxml3
現在我試圖聚集這些文件，以便在地圖不是滿標記在低縮放級別
我的KML文件看起來是這樣的（當然更多的標記（200））
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.2">
<Document>
<Placemark id="1">
<name>test1</name>
<Point>
<coordinates>10.5267012, 49.6812452</coordinates>
</Point>
</Placemark>
<Placemark id="2">
<name>test2</name>
<Point>
<coordinates>30.5267012, 24.6812452</coordinates>
</Point>
</Placemark>
</Document>
</kml>
這裏是我的代碼在我的index.php
<?php ?>

var infoWindow = new google.maps.InfoWindow({maxWidth: 800});
var myParser = new geoXML3.parser({//*** ORIGINAL: only {map: map});
map: map, singleInfoWindow: true,
createMarker: function(placemark) {
//Constructing marker for each Placemark node, and then add it to the markclustere
var point = new google.maps.LatLng(placemark.point.lat, placemark.point.lng);
var marker = new google.maps.Marker({position: point});
markerclusterer.addMarker(marker);
google.maps.event.addListener(marker, "click", function() {
var marker_lat = marker.getPosition().lat();
var marker_lng = marker.getPosition().lng();
infoWindow.close();
infoWindow.setOptions({maxWidth: 800});
content = "<strong>" + placemark.name + "</strong><br>" + placemark.description;
infoWindow.setContent(content);
infoWindow.open(map, marker);
});
markerclusterer.addMarker(marker);
}
});
myParser.parse('./kml/point-load.kml');
}
google.maps.event.addDomListener(window, 'load', initialize);

所以我的問題：爲什麼標記不聚集，甚至不羣不顯示???
[羣集標記從KML使用實施例geoxml3]（http://www.geocodezip.com/geoxml3_test/tanagerproductions_testmapA.html） – geocodezip
