我试图在http://www.geocodezip.com/v3_SO_multipleGeocodedMarkersFromXml.html上做这个教程

我已经在我的服务器上包含了 downloadxml.js，但它仍然不起作用。地图加载但没有地图标记。谁能帮忙，因为我不明白为什么它不起作用。

我看到一些问题..您缺少函数的function声明..因此将第 14 行更改为：geocodeAddress(xmldata)

function geocodeAddress(xmldata)
{
... other code continues here ...

然后它应该可以工作，我还注意到var bounds = new google.maps.LatLngBounds();当你添加标记时你没有扩展你的对象，所以记得添加你的createMarker函数来包含它，像这样：

 function createMarker(latlng, html)
{
  var marker = new google.maps.Marker
            ({
                map: map, 
                position: latlng
            });
 google.maps.event.addListener(marker, 'click', function() {
                info_window.setContent(html);
                info_window.open(map, marker);
            });
    bounds.extend(latlng); // Here we tell what are next viewport bounds
}

经过测试，之后一切正常：）干杯！

请记住在您放置 downloadxml.js 的位置创建脚本文件夹，因为它使用路径为：<script type="text/javascript" src="scripts/downloadxml.js"></script>另外不要忘记添加listings.xml

因此，您需要的文件组织为：

index.html
scripts/downloadxml.js
listings.xml

受 Mauno 解决方案的启发，如果有人提供帮助，我按如下方式解决了这个问题：

function initialize() {
    geocoder = new google.maps.Geocoder();
    info_window = new google.maps.InfoWindow();
    var mapOptions = {
      center: new google.maps.LatLng(40.388397, 0.235348),
      zoom: 6,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    map = new google.maps.Map(document.getElementById("map_canvas"),mapOptions);
}

function codeAddress(data){
    var content = 
            '<div class="bocadillo">' +
                '<div class="titulo">'+
                    '<a href="tienda.php?id='+data.id+'">'+data.nombre+'</a>' +
                '</div>'+
                '<div class="content">'+
                    '<span>Ciudad: </span>'+data.ciudad+'<br />'+
                    '<span>Dirección: </span>'+data.direccion+'<br />'+
                    '<span>Teléfono: </span>'+data.telefono+'<br />'+
                    '<span>Email: </span>'+data.mail+'<br />'+
                '</div>'+
            '</div>'
            ;
    var direccion = data.direccion+", "+data.ciudad+", Spain";
    geocoder.geocode( { 'address': direccion}, function(results, status) 
        {
            if(status == google.maps.GeocoderStatus.OK)
            {
                createMarker(results[0].geometry.location, content);
            }
        });
}

function createMarker(latlng, html){
   var image = "img/general/map_icon.png";
   var marker= new google.maps.Marker(
       {
               map: map, 
               position: latlng,
               icon: image
       });
   google.maps.event.addListener(marker, 'click', function() {
        info_window.setContent(html);
        info_window.open(map, marker);
    });
}

然后，给他们打电话：

$(document).ready(function(){
           initialize();
           for(var i=0;i<markers.length;i++){
               codeAddress(markers[i]);
           }
});
