JS获得当前位置信息

var map = new BMap.Map("allmap");
var point = new BMap.Point(116.331398,39.897445);
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);
});

获得城市名

// 百度地图定位功能
function queryLocation(){
    var map = new BMap.Map("allmap");
    var point = new BMap.Point(116.331398,39.897445);
    var geolocation = new BMap.Geolocation();
    geolocation.getCurrentPosition(function(r){
        if(this.getStatus() == BMAP_STATUS_SUCCESS){
            var mk = new BMap.Marker(r.point);
             nowLng=r.point.lng;
             nowLat=r.point.lat;
        }
        else {
            alert('failed'+this.getStatus());
        }        
    },{enableHighAccuracy: true})
}
