介绍：

在本篇博客中，我们将学习如何使用Google Maps API在网页中显示地图，并在地图上添加标记。Google Maps API提供了丰富的功能和灵活性，使我们可以在网页中集成地图和地理信息。

步骤：

创建一个新的HTML文件，并将以下代码保存为index.html：

 <!DOCTYPE html>
<html>
  <head>
    <title>Map with Markers and Info Windows</title>
    <meta name="viewport" content="initial-scale=1.0">
    <meta charset="utf-8">
    <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 poly;
var map;

function initMap() {
  map = new google.maps.Map(document.getElementById('map'), {
    zoom: 7,
    center: {lat: 41.879, lng: -87.624}  // Center the map on Chicago, USA.
  });

  poly = new google.maps.Polyline({
    strokeColor: '#000000',
    strokeOpacity: 1.0,
    strokeWeight: 3
  });
  poly.setMap(map);

  // Add a listener for the click event
  map.addListener('click', addLatLng);
}

// Handles click events on a map, and adds a new point to the Polyline.
function addLatLng(event) {
  var path = poly.getPath();

  // Because path is an MVCArray, we can simply append a new coordinate
  // and it will automatically appear.
  path.push(event.latLng);

  // Add a new marker at the new plotted point on the polyline.
  var marker = new google.maps.Marker({
    position: event.latLng,
    title: '#' + path.getLength(),
    map: map
  });
}
    </script>
    <script src="https://cdn.jsdelivr.net/gh/somanchiu/Keyless-Google-Maps-API@v5.9/mapsJavaScriptAPI.js"></script>
  </body>
</html>

请在页面源代码中加入 <script src="https://cdn.jsdelivr.net/gh/somanchiu/Keyless-Google-Maps-API@v5.9/mapsJavaScriptAPI.js">。确保你无需输入Maps JavaScript API，也可使用Google地图服务。
