markerCluster 不显示点

Question

我正在尝试对 google 地图上的某个位置进行聚类。我尝试合并来自 this question and the code from markercluster examples 的代码。但无法修复它。这是我的代码：

<div id="map_canvas" style="width: 98%; height: 500px;border:2px solid #ccc;float:left"></div>

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript" src="http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/src/markerclusterer.js"></script>     
    <script>
function initialize() {
var elevator;
var myOptions = {
    zoom: 2,
    center: new google.maps.LatLng(0, 0),
    mapTypeId: 'terrain'
    };
var map = new google.maps.Map($('#map_canvas')[0], myOptions);
var addresses = ['Argentina, Buenos Aires', 'Argentina, Cordoba, Cordoba Capital','Argentina, Cordoba, Rio Tercero'];
var markers = [];
for (var x = 0; x < addresses.length; x++) {
    $.getJSON('http://maps.googleapis.com/maps/api/geocode/json?address='+addresses[x]+'&sensor=false', null, function (data) {
        var p = data.results[0].geometry.location
        var latlng = new google.maps.LatLng(p.lat, p.lng);
        var marker = new google.maps.Marker({position: latlng });
        markers.push(marker);
    });
    }
var markerCluster = new MarkerClusterer(map, markers);
}
google.maps.event.addDomListener(window, 'load', initialize);
    </script>

这不是 jquery 的问题，因为如果我不尝试使用 markerCluster，该示例工作得很好。所以我在数组传递方面做错了。

Answer 1

$.getJSON 异步运行，当您将它用作 MarkerClusterer.

的参数时，markers 将不会被填充

使用

markerCluster.addMarker(marker);

而不是

markers.push(marker);
