百度地图js api的getCurrentPosition返回结果为空是怎么回事

Question

   <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&akhLzWo0VsyW7dGUD5BGaj5xlC4i4a0lKl"></script>
<script type="text/javascript">
        function bd_position() { //百度定位
    var geolocation = new BMap.Geolocation();
    geolocation.getCurrentPosition(function(r){
        if(this.getStatus() == BMAP_STATUS_SUCCESS){
                    console.log(r.address);debugger;
        }
        else {
                 console.log('failed');
        }        
    },{enableHighAccuracy: true})
        }
    </script>

有一半的几率都返回空的对象,有几率又有结果，这样用不了...
问题是这个是什么鬼？
如果这个是判断成功的话那为什么会返回一个空的？
this.getStatus() == BMAP_STATUS_SUCCESS //????

返回的结果
Object {city: "", city_code: 0, district: "", province: "", street: ""…}
city
:
""
city_code
:
0
district
:
""
province
:
""
street
:
""
street_number
:
""

加alert或者console.log(),一步步调试吧
