使用 angular-leaflet-directive 右键单击地图上的标记时如何创建上下文菜单

Question

我是 angular-leaflet-directive 的新手。

我想在右键单击标记时有一个上下文菜单。

我找不到任何 angular 方式的例子。

谁能指导实现它。

angular-leaflet-directive 中是否存在该功能？因为我在文档中找不到任何相关信息。

首先从此 link

下载 angular 上下文菜单所需的文件

这里是例子，

    var app = angular.module("demoapp", ["leaflet-directive"]);
    app.controller('MarkersSimpleController', ['$scope', function($scope) {

      $scope.showCoordinates = function(e) {
        alert(e.latlng);
      }

      var mainMarker = {
        lat: 51,
        lng: 0,
        focus: true,
        draggable: true,
        message: "hey marker",
        contextmenu: true,
        contextmenuWidth: 140,
        contextmenuItems: [{
          text: 'Show coordinates',
          callback: $scope.showCoordinates
        }]
      };
      angular.extend($scope, {
        london: {
          lat: 51.505,
          lng: -0.09,
          zoom: 8

        },
        markers: {
          mainMarker: angular.copy(mainMarker)
        },
        position: {
          lat: 51,
          lng: 0
        },
        events: { // or just {} //all events
          markers: {
            enable: ['dragend']
              //logic: 'emit'
          }
        }
      });
      $scope.$on("leafletDirectiveMarker.dragend", function(event, args) {
        $scope.position.lat = args.model.lat;
        $scope.position.lng = args.model.lng;
      });
    }]);
  </script>
</head>

<body ng-controller="MarkersSimpleController">
  <!-- <leaflet lf-center="london" markers="markers" height="480px" width="100%"></leaflet> EVENTS WILL STILL FIRE but all will for each directive-->
  <!-- NOTICE events attribute is optional it is more for options in whitelisting (enable), blacklisting (disable), and logic (emit or broadcast)  -->
  <leaflet lf-center="london" event-broadcast="events" markers="markers" height="480px" width="100%"></leaflet>
  <h1>Markers simple example</h1>
  <p>Initial marker position (lat/lng): <strong ng-bind="markers.mainMarker.lat"></strong> / <strong ng-bind="markers.mainMarker.lng"></strong></p>
