Google方向不起作用

问题描述

我尝试为我当前的位置和标记坐标指示方向。所以我使用getcurrentposition获取经度和纬度。然后，我标记它。

 函数initialize（）{
 directionsDisplay = new google.maps.DirectionsRenderer（）; 
 var node = new google.maps.LatLng（-7.276442,112.791174）; 
 var mapOptions = {
 zoom：15，
 mapTypeId：google.maps.MapTypeId.ROADMAP 
}; 
 map = new google.maps.Map（document.getElementById（'map'），
 mapOptions）; 
 directionsDisplay.setMap（map）; 
 
 navigator.geolocation.getCurrentPosition（function（position）{
 pos = new google.maps.LatLng（position.coords.latitude，
 position.coords.longitude）; 
 
 var marker = new google.maps.Marker（{
 position：pos，
 map：map，
 title：'Lokasi Anda'
}） ; 
 var marker1 = new google.maps.Marker（{
 position：node，
 map：map，
 title：'Lokasi Anda'
}）; 
 
 map.setCenter（pos）; 
}，function（）{
 handleNoGeolocation（true）; 
}）; 
 
} 
  

然后，我使用这个函数来计算它。

 函数calcRoute（）{
 
 var request = {
 origin：pos，
 destination：node，
 travelMode：google.maps.DirectionsTravelMode.DRIVING 
}; 
 
 directionsService.route（request，function（response，status）{
 if（status == google.maps.DirectionsStatus.OK）{
 directionsDisplay.setDirections（response）; 
} 
}）; 
} 
  

但是为什么我不能从 pos 到节点。任何建议？如果我调用calcRoute函数（并传入pos和node位置，它可以提供任何建议吗？

（在美国）和点位于哪里（Raya Its，Sukolilo，Surabaya City，East Java 60117，Republic of Indonesia）。DirectionsService返回状态ZERO_RESULTS。

 函数calcRoute（pos，node）{
 var directionsService = new google.maps.DirectionsService（）; 
 var request = {
 origin：pos，
 destination：node，
 travelMode：google.maps.DirectionsTravelMode.DRIVING 
}; 
 
 directionsService.route（request，function（响应，状态）{
 if（status == google.maps.DirectionsStatus.OK）{
 directionsDisplay.setDirections（response）; 
} else {alert（Directions fai领导：+状态）; } 
}）; 
} 
  

I try to make directions for my current position and marker coordinate. so i get latitude and longitude using getcurrentposition. then, i mark it.

function initialize() {
  directionsDisplay = new google.maps.DirectionsRenderer();
  var node = new google.maps.LatLng(-7.276442,112.791174);
  var mapOptions = {
    zoom: 15,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById('map'),
      mapOptions);
  directionsDisplay.setMap(map);

    navigator.geolocation.getCurrentPosition(function(position) {
      pos = new google.maps.LatLng(position.coords.latitude,
                                       position.coords.longitude);

      var marker = new google.maps.Marker({
            position : pos,
            map: map,
            title:'Lokasi Anda'
      });
      var marker1 = new google.maps.Marker({
            position : node,
            map: map,
            title:'Lokasi Anda'
      });

      map.setCenter(pos);
    }, function() {
      handleNoGeolocation(true);
    });

}

then, I calculate it using this function.

function calcRoute() {

  var request = {
      origin:pos,
      destination:node,
      travelMode: google.maps.DirectionsTravelMode.DRIVING
  };

  directionsService.route(request, function(response, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(response);
    }
  });
}

but why i can't see direction from pos to node. any suggestion ?

解决方案

If I call the calcRoute function (and pass in the "pos" and "node" locations, it can't find directions between where I am (in the US) and where the point is located (Raya Its, Sukolilo, Surabaya City, East Java 60117, Republic of Indonesia). The DirectionsService returns a status of "ZERO_RESULTS".

working example

function calcRoute(pos,node) {
var directionsService = new google.maps.DirectionsService();
  var request = {
      origin:pos,
      destination:node,
      travelMode: google.maps.DirectionsTravelMode.DRIVING
  };

  directionsService.route(request, function(response, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(response);
    } else { alert("Directions failed: "+status); }
  });
}
