所以现在在 V3 中，现在我无法让标记出现！在警报中获得正确的结果。

var infowindow;
var map;
var latlng;
var lat;
var lng;

function initialize() {
var myLatlng = new google.maps.LatLng(51.949344,7.846573);
var myOptions = {
zoom: 7,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
downloadUrl("example.xml", function(data) {
var markers = data.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
    var address = markers[i].getAttribute("address");
    var geocoder = new google.maps.Geocoder();
    geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
    lat = parseFloat(results[0].geometry.location.lat());
    lng = parseFloat(results[0].geometry.location.lng());


    latlng = new google.maps.LatLng(lat,lng);



alert('Geocode succesful ' + latlng);
} else {
alert("Geocode was not successful for the following reason: " + status);
        }
    });  

   var marker = createMarker(markers[i].getAttribute("name"), latlng);


}
});
}

function createMarker(name, latlng) {
var marker = new google.maps.Marker({position: latlng, map: map});
google.maps.event.addListener(marker, "click", function() {
if (infowindow) infowindow.close();
infowindow = new google.maps.InfoWindow({content: name});
infowindow.open(map, marker);
});
return marker;
}

这个 XML 布局：

    <markers>
    <marker address="XXXXX 2, Rotterdam" name="Info">
    <marker address="XXXXX 25, Amsterdam" name="Info2">
    <marker address="XXXX 52, Rotterdam" name="Info3">
    </markers>

希望您能提供帮助，如果这是一个非常简单的解决方案，请原谅，但我对此有点陌生。

谢谢，E
