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;
}
}
正在进行的全部工作位于http://cspc.net/neighborhoods/map.html。如您所见，地图无法完成加载。正在从 maps.google.com 中创建的自定义地图导出 kml 文件。
我需要修改kml文件吗？
