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

  #map-container {

  #map {

    height: 98%;
  }

</style>

<script src="http://maps.google.com/maps/api/js?sensor=false"></script>

<script type="text/javascript" src="data/weblandmark.json"></script>
<script type="text/javascript" src="js/markerclusterer.js"></script>

<script type="text/javascript">
  function initialize() {
    var center = new google.maps.LatLng(48.133333, 11.566667);

    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.weblandmarks[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);
  }
</script>

我正在使用带有markercluster的地图api来显示许多地方 我可以看到缩放栏，也可以由MarkerCluster生成的群集，但不是实际地图图像 为什么？

Answer 1

Try adding the following CSS:

html { height: 100%; }
body { height: 100%; }

Answer 2

You could try making your map like this:

//The options for the google map
var mapOptions = {
    zoom: 3,
    center: center,
    mapTypeId: google.maps.MapTypeId.ROADMAP //Or whatever you want
};

var map = new google.maps.Map(document.getElementById('#map'), mapOptions);

This is nitpicky but it makes it alot easier to work with the map if you have to add a lot of information to it later (markers/listeners/zooms after load)
