Google Maps API 教程(https://developers.google.com/maps/tutorials/fundamentals/adding-a-google-map)给了我一个空白屏幕。我已经为此工作了 3 个小时,但无法弄清楚。

我什至完全复制/粘贴了代码,它被保存为 .html 文件。

<!DOCTYPE html>
<html>
  <head>
    <style>
      #map_canvas{
        height: 500px;
        width: 400px;
      }
    </style>
    <script src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
    <script>
      function initialize() {
        var map_canvas = document.getElementById('map_canvas');
        var map_options = {
          center: new google.maps.LatLng(44.5403, -78.5463),
          zoom: 8,
          mapTypeId: google.maps.MapTypeId.ROADMAP
        }
        var map = new google.maps.Map(map_canvas, map_options)
      }
       google.maps.event.addDomListener(window, ‘load’, initialize);
    </script>
  </head>

  <body>
    <div id="map_canvas"></div>
  </body>
</html>

您的代码中有非法字符:

Timestamp: 08/12/2013 02:08:39 PM
Error: illegal character
Line: 21, Column: 48
Source Code:
   google.maps.event.addDomListener(window, $(B!F(Bload$(B!G(B, initialize); 

改变:

 google.maps.event.addDomListener(window, ‘load’, initialize);

至:

 google.maps.event.addDomListener(window, "load", initialize);

您需要添加&callback=initialize到您的 URL,该额外参数告诉 Google 这是要调用的函数。该函数必须可从window范围访问。
