var point = new BMapGL.Point(116.404, 39.915);   
var marker = new BMapGL.Marker(point);        // 创建标注   
map.addOverlay(marker);                     // 将标注添加到地图中

定义标注图标 通过Icon类可实现自定义标注的图标，下面示例通过参数MarkerOptions的icon属性进行设置，您也可以使用marker.setIcon()方法。

var myIcon = new BMapGL.Icon("markers.png", new BMapGL.Size(23, 25), {   
    // 指定定位位置。  
    // 当标注显示在地图上时，其所指向的地理位置距离图标左上   
    // 角各偏移10像素和25像素。您可以看到在本例中该位置即是  
    // 图标中央下端的尖角位置。   
    anchor: new BMapGL.Size(10, 25),   
    // 设置图片偏移。  
    // 当您需要从一幅较大的图片中截取某部分作为标注图标时，您  
    // 需要指定大图的偏移位置，此做法与css sprites技术类似。   
    imageOffset: new BMapGL.Size(0, 0 - 25)   // 设置图片偏移   
});     
    // 创建标注对象并添加到地图  
var marker = new BMapGL.Marker(point, {icon: myIcon});   
map.addOverlay(marker); 

JSAPI支持监听覆盖物的事件。

marker.addEventListener("click", function(){   
    alert("您点击了标注");   
});
