我看不出什么问题。。您缺少
geocodeAddress(xmldata)
函数的
声明。。因此,将第14行更改为:

function geocodeAddress(xmldata)
{
... other code continues here ...
然后它应该可以工作了,我还注意到您没有扩展
var bounds=new google.maps.LatLngBounds()createMarker
函数以包含它,如下所示:

 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

受Mauno solution的启发,我解决了以下问题,如果有人帮忙的话:

    var mapOptions = {

    map = new google.maps.Map(document.getElementById("map_canvas"),mapOptions);
}

function codeAddress(data){
    var content = 
            '<div class="bocadillo">' +
