我创建了一个自定义地图，根据数组中保存的位置数据显示标记。现在我正在尝试应用Marker Manager，因为一些标记很接近，可能会导致混淆或可用性问题。
我真的很感激一些帮助，我不确定为什么标记没有显示在地图上，我可能会将标记管理器代码放在错误的位置。
以下完整代码：
(function() {
var map, infowindow, marker;
//Create an array literal to store the weather icons
window.onload = function() {
//Creating a map
var options = {
zoom: 2,
center: new google.maps.LatLng(25,25),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'),options);
var mgr = new MarkerManager(map);
var markers = [];
var locationIcons = [];
//Add the factory icon
locationIcons['factory'] = new google.maps.MarkerImage(
'images/factory.png',
new google.maps.Size(32.0, 37.0),
null,
new google.maps.Point(16.0, 18.0)
);
locationIcons['factoryHover'] = new google.maps.MarkerImage(
'images/factory_over.png',
new google.maps.Size(32.0, 37.0),
null,
new google.maps.Point(16.0, 18.0)
);
locationIcons['office'] = new google.maps.MarkerImage(
'images/office.png',
new google.maps.Size(32.0, 37.0),
null,
new google.maps.Point(16.0, 18.0)
);
locationIcons['officeHover'] = new google.maps.MarkerImage(
'images/office_over.png',
new google.maps.Size(32.0, 37.0),
null,
new google.maps.Point(16.0, 18.0)
);
locationIcons['shadow'] = new google.maps.MarkerImage(
'images/shadow.png',
new google.maps.Size(51.0, 37.0),
null,
new google.maps.Point(16.0, 18.0)
);
