如何在一个页面显示多个百度地图

以下是在页面加入两个地图的效果：
页面核心代码如下:
复制代码 代码如下:
<style type="text/css">
#mapDiv1 { height:400px; width:600px; }
#mapDiv2 { height:400px; width:600px; left:620px; top:-420px;}
</style>
<body>
<div id="mapDiv1" ></div>
<br />
<div id="mapDiv2" ></div>
</body>
</html>
<script type="text/javascript">
//地图初始化
var map1 = new BMap.Map("mapDiv1");
map1.centerAndZoom(new BMap.Point(116.401394,39.915156),12);
map1.enableScrollWheelZoom();
var map2 = new BMap.Map("mapDiv2",{mapType: BMAP_HYBRID_MAP}); //设置卫星图为底图
map2.centerAndZoom(new BMap.Point(116.401394,39.915156),12);
map2.enableScrollWheelZoom();
</script>
以上代码可以实现在同一页面显示两幅并排的地图，如果想要实现拖拽、缩放左边的地图，右边的地图也随着移动、缩放，则只需要给左边的地图注册zoomend和moveend事件即可，代码如下：
复制代码 代码如下:
map1.addEventListener("zoomend", function () {
map2.zoomTo(map1.getZoom());
map2.panTo(map1.getCenter());
});
map1.addEventListener("moveend", function () {
map2.zoomTo(map1.getZoom());
map2.panTo(map1.getCenter());
});
完整代码如下：
