js GPS 百度地圖座標轉換

首先要引用百度地圖的 <scrtipt>:

<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=百度密鑰"></script>
<script type="text/javascript" src="http://developer.baidu.com/map/jsdemo/demo/convertor.js"></script>

而後將 GPS 座標轉換爲百度地圖的座標：

//GPS座標
var xx = 119.51026579044;
var yy = 32.395685050929;
//alert(xx+','+yy);
var gpsPoint = new BMap.Point(xx,yy);

//座標轉換，地理座標轉換成平面座標

BMap.Convertor.translate(gpsPoint,0,translateCallback);

//座標轉換完以後的回調函數
function translateCallback(point){
   //alert(point.lng + "," + point.lat);
   Ds.set('Latitude',point.lng);
   Ds.set('Longitude',point.lat);
   // 百度地圖API功能
   var point = new BMap.Point(point.lng,point.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);
       $scope.dinner.address = addComp.province + addComp.city + addComp.district + addComp.street + addComp.streetNumber;
   });
}
