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 eventmap.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。
