Laravel 地图标记未显示？

Question

我正在尝试让我的 google 地图标记显示到我的 laravel 项目中，但似乎显示了 none 个标记。我在地方上做了一个 dd() ，它表明它正在从数据库中获取信息。但由于某种原因 none 的标记似乎正在显示。

   @section('content')

<div id="map" style="width: 100%; height: 500px;"></div>
     <script type="text/javascript">




                var places = <?php echo json_encode($places); ?>;
                console.log(places);
                var map = new google.maps.Map(document.getElementById('map'), {
                    zoom: 10,
                    center: new google.maps.LatLng(56, -1.56),
                    mapTypeId: google.maps.MapTypeId.ROADMAP
                });
                var infowindow = new google.maps.InfoWindow();

                var marker, i;

                for (i = 0; i < places.length; i++) {
                    marker = new google.maps.Marker({
                        position: new google.maps.LatLng(places[i][1], places[i][2]),
                        map: map
                    });

                    google.maps.event.addListener(marker, 'click', (function(marker, i) {
                        return function() {
                            infowindow.setContent(places[i][0]);
                            infowindow.open(map, marker);
                        }
                    })(marker, i));
                }




            </script>

带控制器：

 public function index()
    {
        //
        $crags = DB::table('places')->get();

        return view('users/map',compact('places'));
    }

这也是我数组的第一项的样子：

0 => {#1312
      +"id": 2
      +"name": "stanage"
      +"location": "sheffield"
      +"latitude": 53
      +"longitude": 2
      +"created_at": "2022-03-03 21:36:49"
      +"updated_at": "2022-03-03 21:36:49"
    }

Answer 1

0 => {#1312
  +"id": 2
  +"name": "stanage"
  +"location": "sheffield"
  +"latitude": 53
  +"longitude": 2
  +"created_at": "2022-03-03 21:36:49"
  +"updated_at": "2022-03-03 21:36:49"
}

您应该访问您的位置数据，例如 place[i].latitude，place[i].longitude 而不是 places[i][1]

marker = new google.maps.Marker({
    position: new google.maps.LatLng(places[i].latitude, places[i].longitude),
    map: map
});
