Google 地图：如何在单个 google 地图中包含多边形和标记

Question

我需要在 Google 地图上组合 2 种绘图。

1: Polygon - https://developers.google.com/maps/documentation/javascript/examples/polygon-arrays

2: Marker - https://developers.google.com/maps/documentation/javascript/examples/infowindow-simple

我尝试合并代码并进行了各种调整，但它不起作用。它显示一个或另一个或空白页。

甚至可以在一张地图上合并 2 张图纸吗？有人可以举一个有效的例子吗？

多边形和标记在同一张地图上的简单示例：

<!DOCTYPE html>
<html>
  <head>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no">
    <meta charset="utf-8">
    <title>Polygon+marker example</title>
    <style>
      /* Always set the map height explicitly to define the size of the div
       * element that contains the map. */
      #map {
        height: 100%;
      }
      /* Optional: Makes the sample page fill the window. */
      html, body {
        height: 100%;
        margin: 0;
        padding: 0;
      }
    </style>
  </head>
  <body>
    <div id="map"></div>
    <script>
      var map;

      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);



        // marker
        var uluru = {lat: 21.5012681, lng: -84.0397756};
        var marker = new google.maps.Marker({
          position: uluru,
          map: map,
          title: 'marker title'
        });


      }

    </script>
    <script async defer
    src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
    </script>
  </body>
</html>

不要忘记添加 google 映射 API 键而不是 YOUR_API_KEY
