处理它的javascript是
function initialize() {
var myLatlng = new google.maps.LatLng(35.910200,-84.085100);
var myOptions = {
zoom: 12,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(
document.getElementById("map_canvas"),
myOptions);
var nyLayer = new google.maps.KmlLayer(
'map.kml',
{ suppressInfoWindows: true,
map: map});
google.maps.event.addListener(nyLayer, 'click', function(kmlEvent) {
var text = kmlEvent.featureData.description;
showInContentWindow(text);
});
function showInContentWindow(text) {
var sidediv = document.getElementById('content_window');
sidediv.innerHTML = text;
}
}
正在进行的总工作是http://cspc.net/neighborhoods/map.html。如您所见，地图无法完成加载。 kml文件是从maps.google.com中创建的自定义地图导出的。
我是否需要修改kml文件？
答案 0 :(得分：2)
问题出在KmlLayer doc构造函数调用中。您必须提供可公开访问的网址，Google可以在其中检索您的kml文件。 Google处理您的kml，将其转换为叠加图块，然后将其作为您使用KmlLayer创建的new google.maps.KmlLayer(...)返回。
