如何在Google中获取KML位置标记值？
如何在Google中获取KML位置标记值？
提问于 2013-12-10 05:18:05
亲爱的，我是谷歌地图API的新手。我在中使用GeoXML3解析了一个KML层。现在，如何在Google 中获取KML的位置标记值(地名)，单击。就像当kml层加载到google地图上，我点击任何标记时，我应该能够在警告框中获取标记的放置值。请找到帮助我在上解析kml的代码。请指点。

这就是你要找的吗？我在onclick函数中添加了警报，它在警报框中显示了placemark的名称。如果你发现任何问题，请检查并通知我。

如果使用"afterParse“函数将单击侦听器添加到标记中，则可以访问数据(如果使用函数闭包)，例如访问名称：
// assign "useTheData" as the after parse function
var geoXml = new geoXML3.parser({map: map, singleInfoWindow: true, afterParse: useTheData});
geoXml.parse('kmload.kml');
// function to retain closure on the placemark and associated text
function bindPlacemark(placemark, text) {
google.maps.event.addListener(placemark,"click", function() {alert(text)});
}
// "afterParse" function, adds click listener to each placemark to "alert" the name
function useTheData(doc) {
for (var i = 0; i < doc[0].placemarks.length; i++) {
var placemark = doc[0].placemarks[i].polygon || doc[0].placemarks[i].marker || doc[0].placemarks[i].polyline;
bindPlacemark(placemark, doc[0].placemarks[i].name);
}
