Question

我真的希望你能帮到我，因为我整天都把头发拉出来！我们正在开发一个房地产代理网站，作为其中的一部分，我希望为主页开发一个集群地图，该地图将链接到所有房产。

我有地图从我添加的地址中对几个虚拟位置进行地理编码，但是当我添加代码来创建群集时，它似乎不起作用。我开始认为我没有为此添加足够的位置来点击，但我见过的演示只有2个标记。

到目前为止，我的代码如下：

<script type="text/javascript">

    function initialize() {

        var myOptions = {center: new google.maps.LatLng(54, -2), zoom: 2, mapTypeId: google.maps.MapTypeId.ROADMAP};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var addressArray = new Array("3 Ard Na Cluana, Warrenpoint, BT34 3GY","19 Great Georges Street, Warrenpoint","Warrenpoint","BT34 3FS","15 Ard Na Cluana, Warrenpoint, BT34 3GY","10 Carrowmenagh Lane, Maghera","Belfast","49.286955, -123.118479");
var geocoder = new google.maps.Geocoder();
var markerBounds = new google.maps.LatLngBounds();

        var markers = [];

        for (var i = 0; i < 100; i++) {

            geocoder.geocode( { "address": addressArray[i]}, function(results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
                var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location});
                markers.push(marker);
                markerBounds.extend(results[0].geometry.location);
map.fitBounds(markerBounds);
            }
});
}

        var markerCluster = new MarkerClusterer(map, markers);
        }

</script>

</head>

<body>
<div id="map_canvas" style="width:600px; height: 400px;">&nbsp;</div>
<script type="text/javascript">
initialize();
</script>
</body>
</html>

如果您可以测试并提供任何帮助或建议，我将非常感激！

提前致谢！

geocode()是异步方法，需要一些时间才能完成。在markerCluster填充之前创建markers。一种选择是在markerCluster循环之前创建for并使用

markerCluster.addMarker(marker, true);

geocode()方法中的

。例如：

        var markerCluster = new MarkerClusterer(map, markers);

        for (var i = 0; i < 100; i++) {

            geocoder.geocode( { "address": addressArray[i]}, function(results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
                var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location});
                markers.push(marker);
                markerBounds.extend(results[0].geometry.location);
map.fitBounds(markerBounds);

                markerCluster.addMarker(marker, true);
            }
});
}

        //var markerCluster = new MarkerClusterer(map, markers);
        }

为什么我的自定义Google地图中没有看到任何标记群集？
