MarkerClusterer没有标记集群 [英] MarkerClusterer not clustering markers

问题描述

我的地图是pretty低迷，由于大量的存储位置的数据/标记，所以我就先markerclusterer工作显示<一个href=\"http://google-maps-utility-library-v3.google$c$c.com/svn/trunk/markerclusterer/docs/examples.html\"相对=nofollow>此处。位置仅仅是一个C＃字符串数组，具有名称，纬度和每个标记经度。
出于某种原因，图仍然有效，只是显示个人标记，并且不聚集他们，我想不通为什么。任何帮助将是AP preciated。

 ＆LT;脚本类型=文/ JavaScript的＆GT;    无功位置=并[d（％）=地点％]的计算值;    VAR地图=新google.maps.Map（的document.getElementById（'地图'）{
        变焦：10，
        中心：新google.maps.LatLng（30.2979536，-97.7470835）
        mapTypeId设为：google.maps.MapTypeId.ROADMAP
    }）;    变种标记= [];    对于（VAR I = 0; I＆LT; locations.length;我++）{
        VAR的标记=新google.maps.Marker（{位置：新google.maps.LatLng（位置[I] [1]，位置[I] [2]），地图：地图}）;
        markers.push（标记）;
    }  VAR markerCluster =新MarkerClusterer（标记）;
＆LT; / SCRIPT＆GT;
 

解决方案

• 删除地图：地图在您添加标记的选项。



• 地图传递到MarkerClusterer

    VAR markerCluster =新MarkerClusterer（地图，标记）;
   

您可能想的纬度和经度浮点数转换字符串（与parseFloat（））。

工作的例子有MarkerClusterer

My map is pretty sluggish due to the large amount of data/markers stored in locations so I tried to get markerclusterer working shown here. Locations is just a c# string array that has a name, latitude, and longitude for each marker. For some reason the map still works but just shows individual markers and does not cluster them and I cannot figure out why. Any help would be appreciated.

<script type="text/javascript">

    var locations = [<%=locations%>];

    var map = new google.maps.Map(document.getElementById('map'), {
        zoom: 10,
        center: new google.maps.LatLng(30.2979536, -97.7470835),
        mapTypeId: google.maps.MapTypeId.ROADMAP
    });

    var markers = [];

    for (var i = 0; i < locations.length; i++) {
        var marker = new google.maps.Marker({position: new  google.maps.LatLng(locations[i][1], locations[i][2]), map: map });
        markers.push(marker);
    }

  var markerCluster = new MarkerClusterer(markers);
</script>

解决方案

• remove map: map from the options in the markers you add.

• pass the map into the MarkerClusterer

  var markerCluster = new MarkerClusterer(map, markers);
  

You might want to convert the latitude and longitude to floating point numbers from strings (with parseFloat()).
