我的代码有点问题,我不知道它是什么。我正在托盘绘制到地点之间的方向,但代码不起作用。我尝试使用此页面:https ://developers.google.com/maps/documentation/javascript/directions#TravelModes但我无法得到它。谢谢 !这是代码:

    $(document).ready(function() {

        $('#Encuentrame').click(function() {
            if (navigator.geolocation) {
                navigator.geolocation.getCurrentPosition(exito, error);
            } else {
                error('El navegador no soporta GeoLocalizacion');
            }
        });
    });  




    function exito(position) {
      var marcadorCasa = new google.maps.LatLng(-34.5688496,-58.4322009); //establece la posicion de un marcador que elijo
      var plazaDeMayo = new google.maps.LatLng(-34.60841643923174,-58.37216913700104);
      var directionsDisplay;
      directionsDisplay = new google.maps.DirectionsRenderer();
      var directionsService = new google.maps.DirectionsService();
      var latlng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
      var myOptions = {
        zoom: 19,
        center: latlng,
        mapTypeControl: false,
        navigationControlOptions: {style: google.maps.NavigationControlStyle.SMALL},
        mapTypeId: google.maps.MapTypeId.ROADMAP
      };
      var mapcanvas = $('#mapcanvas');
      var map = new google.maps.Map(mapcanvas[0], myOptions);
      var marker = new google.maps.Marker({
          position: latlng,
          map: map, 
          title:"Creo que estoy aca !"
      });
      directionsDisplay.setMap(map);
      var lugarCasa = new google.maps.Marker({
        position:marcadorCasa,
        map:map,
        title:"CASA",
        animation: google.maps.Animation.BOUNCE
      });
      var plaza = new google.maps.Marker({
        position:plazaDeMayo,
        map:map,
        animation: google.maps.Animation.BOUNCE,
        title:"Plaza de Mayo"
      });

      var requerimientoDeDirecciones = new google.maps.DirectionsRequest({
        origin: latlng,
        destination: LugarCasa,
        travelMode: google.maps.TravelMode.BICYCLING,
        unitSystem: UnitSystem.METRIC,
      });

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

    }

您的代码中有一些错误:

  • google.maps.DirectionsRequest并不存在。Google Maps 文档没有指明任何构造函数。它应该被定义为一个匿名对象。
  • origin并且destination必须是google.maps.LatLngor StringLugarCasa在您的代码中并非如此。
  • 您使用UnitSystem.METRIC的是google.maps.UnitSystem.METRIC.

这是一个工作版本:

var requerimientoDeDirecciones = {
  origin: latlng,
  destination: marcadorCasa,
  travelMode: google.maps.TravelMode.BICYCLING,
  unitSystem: google.maps.UnitSystem.METRIC
};
