            var opts = {
                title: '行政区划归属',
                width: 220,
                height: 92
            };
            var infoStr = '<div>省：' + rs.addressComponents.province + '</div>'
                + '<div>市：' + rs.addressComponents.city + '</div>'
                + '<div>区：' + rs.addressComponents.district + '</div>';
            var infoWindow = new BMap.InfoWindow(infoStr, opts);
            map.openInfoWindow(infoWindow, point);

        });
    });
}

其中 $("input[name='serviceAddress']").val(rs.address); 赋值给 input 框
