专家坐堂-百度API调用的经纬度和实际GPS存在的误差，怎样解决？Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

下面是一段网页源码，是转换GPS为百度坐标的，求怎么改为狐表代码运用

<!DOCTYPE html>

body, html,#allmap {width: 100%;height: 100%;overflow: hidden;margin:0;}

#l-map{height:100%;width:78%;float:left;border-right:2px solid #bcbcbc;}

//GPS坐标

var xx = 115.439365 ;

var yy = 30.242607;

var gpsPoint = new BMap.Point(xx,yy);

//地图初始化

var bm = new BMap.Map("allmap");

bm.centerAndZoom(gpsPoint, 15);

bm.addControl(new BMap.NavigationControl());

//添加谷歌marker和label

var markergps = new BMap.Marker(gpsPoint);

bm.addOverlay(markergps); //添加GPS标注

var labelgps = new BMap.Label("GPS",{offset:new BMap.Size(20,-10)});

markergps.setLabel(labelgps); //添加GPS标注

//坐标转换完之后的回调函数

translateCallback = function (point){

var marker = new BMap.Marker(point);

bm.addOverlay(marker);

var label = new BMap.Label("实际坐标",{offset:new BMap.Size(20,-10)});

marker.setLabel(label); //添加百度label

bm.setCenter(point);

alert(point.lng + "," + point.lat);

}

setTimeout(function(){

BMap.Convertor.translate(gpsPoint,0,translateCallback); //真实经纬度转成百度坐标

}, 2000);
