var map = new BMap.Map("container");//初始化地图
map.addControl(new BMap.NavigationControl()); //初始化地图控件
map.addControl(new BMap.ScaleControl());
map.addControl(new BMap.OverviewMapControl());
var point=new BMap.Point(116.404, 39.915);
map.centerAndZoom(point, 15);//初始化地图中心点
var marker = new BMap.Marker(point); //初始化地图标记
marker.enableDragging(); //标记开启拖拽
var gc = new BMap.Geocoder();//地址解析类
//添加标记拖拽监听
marker.addEventListener("dragend", function(e){
//获取地址信息
gc.getLocation(e.point, function(rs){
showLocationInfo(e.point, rs);
});
});
//添加标记点击监听
marker.addEventListener("click", function(e){
gc.getLocation(e.point, function(rs){
showLocationInfo(e.point, rs);
});
});
map.centerAndZoom(point, 15); //设置中心点坐标和地图级别
map.addOverlay(marker); //将标记添加到地图中
//显示地址信息窗口
function showLocationInfo(pt, rs){
var opts = {
width : 250, //信息窗口宽度
height: 100, //信息窗口高度
title : "" //信息窗口标题
}
var addComp = rs.addressComponents;
var addr = "当前位置：" + addComp.province + ", " + addComp.city + ", " + addComp.district + ", " + addComp.street + ", " + addComp.streetNumber + "
";
addr += "纬度: " + pt.lat + ", " + "经度：" + pt.lng;
//alert(addr);
//var infoWindow = new BMap.InfoWindow(addr, opts); //创建信息窗口对象
//marker.openInfoWindow(infoWindow);
