百度地圖獲取兩點間距離

以下為根據地點名稱獲取兩點之間距離

var map = new BMap.Map("allmap"); // 創建Map實例
map.centerAndZoom(new BMap.Point(116.404, 39.915), 11); // 初始化地圖,設置中心點坐標和地圖級別

var searchComplete = function (results){
  if (transit.getStatus() != BMAP_STATUS_SUCCESS){
    return ;
  }
  var plan = results.getPlan(0);
  var distance = plan.getDistance(false)/1000
  console.log('距離'+distance.toFixed(2)+'公里')
  // alert(distance)
}
var transit = new BMap.DrivingRoute(map, {renderOptions: {map: map},
  onSearchComplete: searchComplete
});
transit.search(SendAdd + sendDetail, ReceiveAdd + receiveDetail);
