I recently created a store locator using the "Google Maps API Store Locator" example.

Now I'm trying to implement the MarkerClusterer Library so that I can display a large single marker instead of multiple markers when users are zoomed out at a certain distance.

When I add the output code:

... 

GDownloadUrl(searchUrl, function(data) {

var xml = GXml.parse(data);

var markers = xml.documentElement.getElementsByTagName('marker');

map.clearOverlays();

var markerCluster = new MarkerClusterer(map, markers);

...

I get the following error:

marker.getLatLng is not a function

Has anyone tried to implement this piece in the past?

我认为您正在尝试将一些 Google Maps v2 或可能 v1 代码与 v3 api 一起使用，因此您收到错误“getLatLng 不是函数”。

试试 v3 标记集群库：

这是一个例子：
