百度地图实现自动定位，周围目标检索，路线规划及面板导航功能（只贴出了JS）

首先得引入你的AK这里就不说了

var url = decodeURI(window.location.href);
//var url=window.location.href;
var data = url.split("?")[1];
var datas = data.split(",");
$("#h3").html(datas[3]);

var map = new BMap.Map("l-map");

var lng, lat;
var geolocation = new BMap.Geolocation();
var geoc = new BMap.Geocoder();
//------------------ 
// 开启SDK辅助定位
geolocation.enableSDKLocation();
geolocation
.getCurrentPosition(function(r) {
if (this.getStatus() == BMAP_STATUS_SUCCESS) {


//map.panTo(r.point);
lng = r.point.lng;
lat = r.point.lat;
//  alert('您的位置：'+r.point.lng+','+r.point.lat);
var mpoint = new BMap.Point(r.point.lng, r.point.lat);
map.centerAndZoom(mpoint, 14);
//缩放控件
map.addControl(new BMap.NavigationControl());
//比例尺控件
map.addControl(new BMap.ScaleControl());
//定位控件
map.addControl(new BMap.GeolocationControl());
var mk = new BMap.Marker(r.point);
map.addOverlay(mk);
map.addControl(new BMap.MapTypeControl()); //添加地图类型控件
map.enableScrollWheelZoom(true); //开启鼠标滚轮缩放
map.enableDragging(); //标记开启拖拽 
//--------------------------------------

//解析地址,并规划路线
//根据经纬度
