我们如何在谷歌地图中为多边形应用可编辑标记

我正在研究多边形距离区域，有了这个我想添加标记并想获得它之间的距离，我找到了代码，但我无法编辑该多边形区域也无法添加标记，我尝试了很多，但它对我不起作用，任何人都可以为此帮助我，如何解决此问题？

      var map;
      var infoWindow;
      function initMap() {
        map = new google.maps.Map(document.getElementById('map'), {
          zoom: 5,
          center: {lat: 24.886, lng: -70.268},
          mapTypeId: 'terrain'
        });
        // Define the LatLng coordinates for the polygon.
        var triangleCoords = [
            {lat: 25.774, lng: -80.190},
            {lat: 18.466, lng: -66.118},
            {lat: 32.321, lng: -64.757}
        ];
        // Construct the polygon.
        var bermudaTriangle = new google.maps.Polygon({
          paths: triangleCoords,
          strokeColor: '#FF0000',
          strokeOpacity: 0.8,
          strokeWeight: 3,
          fillColor: '#FF0000',
          fillOpacity: 0.35
        });
        bermudaTriangle.setMap(map);
        // Add a listener for the click event.
        bermudaTriangle.addListener('click', showArrays);
        infoWindow = new google.maps.InfoWindow;
      }
      /** @this {google.maps.Polygon} */
      function showArrays(event) {
        // Since this polygon has only one path, we can call getPath() to return the
        // MVCArray of LatLngs.
        var vertices = this.getPath();
        var contentString = '<b>Bermuda Triangle polygon</b><br>' +
            'Clicked location: <br>' + event.latLng.lat() + ',' + event.latLng.lng() +
            '<br>';
        // Iterate over the vertices.
        for (var i =0; i < vertices.getLength(); i++) {
          var xy = vertices.getAt(i);
          contentString += '<br>' + 'Coordinate ' + i + ':<br>' + xy.lat() + ',' +
              xy.lng();
        }
        // Replace the info window's content and position.
        infoWindow.setContent(contentString);
        infoWindow.setPosition(event.latLng);
        infoWindow.open(map);
      }

要添加标记，请编辑脚本并将此代码放在 triangleCoords 下：

// Add Markers to Coordinates
    for(var i = 0; i < triangleCoords.length; i++) {
      var pos = triangleCoords[i];
      var marker = new google.maps.Marker({
        map: map,
        position: pos,
        draggable: true
      });
      marker.setMap(map);
      markers.push(marker);
    }

要对标记执行一些特定的操作，请转到此处：了解标记要获取距离，请使用距离矩阵：了解距离矩阵

希望能帮助你动起来。JSBin：带标记的代码副本
