我不确定这是什么原因。我复制了示例代码并尝试在本地主机上的 Dreamweaver 中运行它。但由于某些原因，我没有看到地图被加载。我记得之前它曾经加载它，但现在它没有加载.我有有效的 api 密钥，但我的网站仍未公开。

这是最简单的代码，但我仍然无法启动它。

enter code here

键值请求 GET /maps/api/js/QuotaService.RecordEvent?1shttp%3A%2F%2Flocalhost%2Fgeoc.html&4e1&5e0&6u1&7sc7c7sc&callback= xdc ._papnzo&token=120226 HTTP/1.1

有人可以看看并建议我如何解决这个问题吗？我必须对地址进行地理编码，然后将其传递给 places api。

您需要为地图设置大小，这对我有用：

<div id="map_canvas" style="height:500px;width:600px;"></div>

或者这个CSS：

body, html, #map_canvas {
  height: 100%;
  width: 100%;
}

工作示例

代码片段：

var geocoder;
var map;

function initialize() {
  geocoder = new google.maps.Geocoder();
  var latlng = new google.maps.LatLng(-34.397, 150.644);
  var mapOptions = {
    zoom: 8,
    center: latlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  }
  map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
}

function codeAddress() {
  var address = document.getElementById('address').value;
  geocoder.geocode({
    'address': address
  }, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      map.setCenter(results[0].geometry.location);
      var marker = new google.maps.Marker({
        map: map,
        position: results[0].geometry.location
      });
    } else {
      alert('Geocode was not successful for the following reason: ' + status);
    }
  });
}
google.maps.event.addDomListener(window, 'load', initialize);
body,
html,
#map_canvas {
  height: 100%;
  width: 100%;
}
<script src="https://maps.googleapis.com/maps/api/js"></script>
<div>
  <input id="address" type="textbox" value="126 Beacon Avenue Jersey City NJ 07306 USA">
  <input type="button" value="Geocode" onclick="codeAddress()">
</div>
<div id="map_canvas"></div>
