在谷歌地图组标记

Question

我发现这个很棒的教程效果很好。http://lab.abhinayrathore.com/ipmapper/

下面是从IP地址返回lat&lon值的javascript代码:http://pastebin.com/1gE91nuh

所以在同一个地方有很多标记，我想把它们分组成这样:http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerclustererplus/2.0.9/examples/simple_example.html

的例子:http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerclustererplus/2.0.9/docs/examples.html

但是有人能告诉我如何在原始代码中创建组吗?(原代码:http://pastebin.com/1gE91nuh)

谢谢!

这是创建标记集群的代码。当创建标记时，它们被压入数组。该数组被传递给一个新的MarkerClusterer对象。

  function initialize() {
    var center = new google.maps.LatLng(37.4419, -122.1419);
    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 3,
      center: center,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    });
    var markers = [];
    for (var i = 0; i < 100; i++) {
      var dataPhoto = data.photos[i];
      var latLng = new google.maps.LatLng(dataPhoto.latitude,
          dataPhoto.longitude);
      var marker = new google.maps.Marker({
        position: latLng
      });
      markers.push(marker);
    }
    var markerCluster = new MarkerClusterer(map, markers);
  }
  google.maps.event.addDomListener(window, 'load', initialize);
