Javascript 如何在我的地图中使用MarkerClusterer

我想在我的地图上使用MarkerClusterer，但我不太懂JavaScript

如何将MarkerClusterer与我的地图一起使用

我需要添加cluster命令，但我不太懂编码。我的代码在下面

var LocationData = [ 

     [49.2814064, -123.1025187, "71 E Hastings St, Vancouver" ], 
     [49.2812336, -123.1020622, "122 E Hastings St, Vancouver" ], 
     [49.2813564, -123.1012253, "138 E Hastings St, Vancouver" ], 
    [49.2811625, -123.0985032, "242 E Hastings St, Vancouver" ]
];

function initialize() {
    var map =
        new google.maps.Map(document.getElementById('map_canvas'));
    var bounds = new google.maps.LatLngBounds();
    var infowindow = new google.maps.InfoWindow();

    for (var i in LocationData) {
        var p = LocationData[i];
        var latlng = new google.maps.LatLng(p[0], p[1]);
        bounds.extend(latlng);

        var marker = new google.maps.Marker({
            position: latlng,
            map: map,
            title: p[2]
        });

        google.maps.event.addListener(marker, 'click', function () {
            infowindow.setContent(this.title);
            infowindow.open(map, this);
        });
    }

    map.fitBounds(bounds);
}


google.maps.event.addDomListener(window, 'load', initialize);
google.maps.event.addListener(marker, 'click', function () {
    infowindow.setContent(p[2]);
    infowindow.open(map, marker);
});

您必须添加指向markerclusterer库的链接，如：

<script src='markerclusterer.js'></script>

---

然后缩小以使群集可见。

在创建标记的循环中，您希望将创建的每个标记存储在一个数组中，然后将对地图和该数组的引用传递给群集构造函数：

var markers = [],
    i, l
    marker,
    markerCluster;

for (i = 0, l = LocationData.length; i < l; i += 1) {
    ...
    marker = new google.maps.Marker({ // whatever you need to pass in here });
    markers.push(marker);
}
markerCluster = new MarkerClusterer(map, markers);  

var标记=[]，
i、 l
标记，
标记聚类；
对于（i=0，l=LocationData.length；i

---

另外，避免使用for/in在数组中循环，只使用常规的for循环

您使用的是哪个集群插件，到目前为止您尝试了什么？像Google MarkerClusterer一样

var markers = [],
    i, l
    marker,
    markerCluster;

for (i = 0, l = LocationData.length; i < l; i += 1) {
    ...
    marker = new google.maps.Marker({ // whatever you need to pass in here });
    markers.push(marker);
}
markerCluster = new MarkerClusterer(map, markers);
