Question

我正在努力让Google地图指南与地理定位一起使用（使用Google地图提供的示例）。单独工作，但结合时有一个问题，地图不会显示路径（但自动完成工作正常）。

use admin
db.createUser({user:"RootAdmin",pwd:"blahblah",roles:["root"]})

Answer 1

我已尝试将路径放在不同的位置，并最终使其工作。 @Jaromanda X - 感谢您的想法：）

 function initMap() {


if (navigator.geolocation){
    navigator.geolocation.getCurrentPosition(function(position){
      var map = new google.maps.Map(document.getElementById('map'), {
          mapTypeControl: false,
          center: {lat:position.coords.latitude, lng:position.coords.longitude},
          zoom: 10
        });

     var marker2 = new google.maps.Marker({
  position: {lat:50.671064, lng:17.926138},

      };

      AutocompleteDirectionsHandler.prototype.setupPlaceChangedListener = function(autocomplete, mode) {
        var me = this;
        autocomplete.bindTo('bounds', this.map);
        autocomplete.addListener('place_changed', function() {

            return;
          }
          if (mode === 'ORIG') {

          return;
        }
        var me = this;

        this.directionsService.route({
          origin: {'placeId': this.originPlaceId},
          destination: {'placeId': this.destinationPlaceId},
          travelMode: this.travelMode
        }, function(response, status) {
          if (status === 'OK') {
            me.directionsDisplay.setDirections(response);
          } else {
            window.alert('Directions request failed due to ' + status);
          }


            map.setStreetView(panorama);

        });

      };
}
}

当我添加地理位置时，Google地图中的路线停止工作
