我想要搜索KML文件以查看某個特定地址是否屬於疊加層。目前，我已將地址轉換爲地理編碼。但是，我不確定添加此功能需要什麼代碼。Google Maps API V3搜索KML文件
下面是本次代碼：
function initialize() {
var infowindow = new google.maps.InfoWindow({
content: '',
suppressMapPan:true
});
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 d = new Date();
var n = d.getMilliseconds();
var nyLayer = new google.maps.KmlLayer(
'http://www.cspc.net/neighborhoods/groups.kml?rand=' + n,
{ suppressInfoWindows: true, map: map});
google.maps.event.addListener(nyLayer, 'click', function(kmlEvent) {
var url = kmlEvent.featureData.snippet;
var groupName = kmlEvent.featureData.name;
var insideContent = "<div style='width:250px;'><h2>" + groupName +
"</h1><p>We have a neighborhood contact in your area! </p>" +
"<p><a href='" + url + "' target='_blank'>Get connected!</a>" +
" They look forward to hearing from you.</p><p>If you have " +
"any additional questions, please contact our " +
"<a href='http://www.cspc.net/communitylife' target='_blank'>" +
"Community Life</a> staff for more information. Betsy Palk, " +
"the Administrative Assistant, may be reached at:<br/><br/>" +
"<b>Email:</b> <a href='mailto:[email protected]'>" +
"[email protected]</a><br/><b>Phone:</b> 865-291-5268<p></div>";
var clickPos = kmlEvent.latLng;
var posX = new google.maps.LatLng(clickPos.lat(), clickPos.lng());
infowindow.close();
infowindow.setPosition(posX);
infowindow.setContent(insideContent);
infowindow.open(map);
});
eventMapClick = google.maps.event.addListener(map, 'click',
function(event) {
var marker = new google.maps.Marker({ position: event.latLng });
var outsideContent = "<div style='width:250px;'><h2>Oops!</h1>" +
"<p> It seems we don't have a neighborhood contact in your " +
"area.</p><p>Please contact our <a " +
"href='http://www.cspc.net/communitylife' target= '_blank'>" +
"Community Life</a> staff for more information. " +
"Betsy Palk, the Administrative Assistant, may be reached at:" +
"<br/><br/><b>Email: </b> <a href='mailto:[email protected]'>" +
"[email protected]</a><br/><b>Phone:</b> 865-291-5268<p></div>";
infowindow.setContent(outsideContent);
infowindow.open(map, marker);
});
}
var geocoder = new google.maps.Geocoder();
function searchAddress(address) {
geocoder.geocode(
{'address': address},
function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var loc = results[0].geometry.location;
// use loc.lat(), loc.lng()
window.alert(loc);
}
else {
window.alert("Not found: " + status);
}
}
);
};
