Question

我刚开始为Google地图编码。我一直试图使用自定义图像图块（Out of World of Warcraft）制作自己的地图，我一直在这里关注指南：http://facepunch.com/showthread.php?t=1184658

我得到了地图显示和所有类似的工作。但现在我正在尝试添加标记，它们不会出现，任何人都可以帮忙吗？

继承我的代码:(没有标记代码。）

参见documentation on adding Markers，要将标记添加到地图，请使用“地图”属性

  var marker = new google.maps.Marker({
    position: map.getCenter(),
    map: map,
    title: "Hello World!"
  });

代码段

function initialize() {
  var mapOptions = {
    minZoom: 2,
    maxZoom: 7,
    isPng: true,
    mapTypeControl: false,
    streetViewControl: false,
    center: new google.maps.LatLng(0, 0),
    zoom: 3,
    mapTypeControlOptions: {
      mapTypeIds: ['custom', google.maps.MapTypeId.ROADMAP],
      style: google.maps.MapTypeControlStyle.DROPDOWN_MENU
    }

  };
  map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);

  map.mapTypes.set('custom', CustomMapType);
  map.setMapTypeId('custom');

  // To add the marker to the map, use the 'map' property
  var marker = new google.maps.Marker({
    position: map.getCenter(),
    map: map,
    title: "Hello World!"
  });
}
google.maps.event.addDomListener(window, 'load', initialize);

function CustomMapType() {}
CustomMapType.prototype.tileSize = new google.maps.Size(256, 256);
CustomMapType.prototype.maxZoom = 7;
CustomMapType.prototype.getTile = function(coord, zoom, ownerDocument) {
  var div = ownerDocument.createElement('DIV');
  var baseURL = 'http://d1m6g5gl70bc4l.cloudfront.net/';
  baseURL += zoom + '_' + coord.x + '_' + coord.y + '.png';
  div.style.width = this.tileSize.width + 'px';
  div.style.height = this.tileSize.height + 'px';
  div.style.backgroundColor = '#1B2D33';
  div.style.backgroundImage = 'url(' + baseURL + ')';
  return div;
};

CustomMapType.prototype.name = "Custom";
CustomMapType.prototype.alt = "Tile Coordinate Map Type";
var map;
var CustomMapType = new CustomMapType();

html {
  height: 100%
}
body {
  height: 100%;
  margin: 0px;
  padding: 0px
}
#map_canvas {
  height: 100%;
  z-index: 0;
}
#gmnoprint {
  width: auto;
}
