Question

好的，所以我开发了以下代码，将Google Maps与Marker Clusterer一起使用。我在网站上使用了这个例子并稍微修改了它以获取我的json数据。我的问题是，我没有得到任何错误，但它也没有工作。我在这里做错了什么？

由于

<head>
    <style type="text/css">
        body {
            margin: 0;
            padding: 10px 20px 20px;
            font-family: Arial;
            font-size: 16px;
        }

        #map-container {
            padding: 6px;
            border-width: 1px;
            border-style: solid;
            border-color: #ccc #ccc #999 #ccc;
            -webkit-box-shadow: rgba(64, 64, 64, 0.5) 0 2px 5px;
            -moz-box-shadow: rgba(64, 64, 64, 0.5) 0 2px 5px;
            box-shadow: rgba(64, 64, 64, 0.1) 0 2px 5px;
            width: 600px;
        }

        #map {
            width: 600px;
            height: 400px;
        }
    </style>

Answer 1

没有添加标记，因为

for (var i = 0; i < data.length; i++) {

应该是

for (var i = 0; i < data.users.length; i++) {

MarkerClusterer V3没有错误但没有工作
