我需要 Google 地图方面的帮助。我想创建一个可以使用多个指针显示多个地址的地图。问题是所有地址都显示最后一个地址的指针图标。它可能与异步 geocoder.geocode 有关，但我是 JS 初学者，我无法解决这个问题。

有人可以帮忙吗？谢谢。

试试这个代码：

var marker, i;

for (i = 0; i < locations.length; i++) {  
  marker = createMarker(locations[i]);
}
function createMarker(location) {
  var image = new google.maps.MarkerImage('http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=' + location[2] + '|FF0000|000000',
        new google.maps.Size(21, 34),
        new google.maps.Point(0,0),
        new google.maps.Point(10, 34)
    );

    var geocoder = new google.maps.Geocoder();
    geocoder.geocode( { 
        'address': location[1]
    }, function(results, status){

        if (status == google.maps.GeocoderStatus.OK) {

             marker = new google.maps.Marker({
                position: results[0].geometry.location,
                map: map, 
                icon: image
            });
        } 
    });
}
