百度js 获取定位城市名称

首先引用百度 script

<script type="text/javascript" src="http://api.map.baidu.com/api?type=quick&ak=百度密钥&v=1.0"></script>

然后js

<script type="text/javascript">

var geolocation = new BMap.Geolocation();
geolocation.getCurrentPosition(function(r){
if(this.getStatus() == BMAP_STATUS_SUCCESS){
var mk = new BMap.Marker(r.point);
GetLocation(r.point.lng,r.point.lat);
}
else {
alert('failed'+this.getStatus());
}
},{enableHighAccuracy: true})

function GetLocation(lng,lat){
var point = new BMap.Point(lng,lat);
var gc = new BMap.Geocoder();
gc.getLocation(point, function(rs){
var addComp = rs.addressComponents;
alert(addComp.province + ", " + addComp.city + ", " + addComp.district + ", " + addComp.street + ", " + addComp.streetNumber);
});
}

</script>
