百度地图jsAPI自带功能即可实现自动定位的功能，PC端定位不是很精确，手机移动端的自动定位误差不大。
自动定位状态提示;
```javascript
geolocationControl.addEventListener("locationSuccess", function (e) {
var address = '';
address += e.addressComponent.province;
address += e.addressComponent.city;
address += e.addressComponent.district;
address += e.addressComponent.street;
address += e.addressComponent.streetNumber;
console.log("当前定位地址为：" + address);
});
geolocationControl.addEventListener("locationError", function (e) {
console.log(e.message);
});
map.addControl(geolocationControl);
/自动获取当前定位的经纬度 - Begin/
var geolocation = new BMap.Geolocation();
geolocation.getCurrentPosition(function ® {
if (this.getStatus() == BMAP_STATUS_SUCCESS) {
var localPoint = r.point;
console.log(localPoint);
} else {
alert(‘failed’ + this.getStatus());
}
});
/自动获取当前定位 - End/
```javascript
/*添加定位控件*/
var geolocationControl = new BMap.GeolocationControl({
anchor: BMAP_ANCHOR_BOTTOM_LEFT,//控件的停靠位置
offset:new BMap.Size(10,40),//偏移距离
//showAddressBar:false,
locationIcon:new BMap.Icon("images/icon.png", new BMap.Size(23, 24))//定位中心点的Icon样式
});
Done!
