GPS坐标转换 百度地图API调用

	//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("我是百度标注哦",{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);
