问题是：

• 我没有使用API​​密钥（尽管它不认为这是恶意的，但它工作）


• 我没有设置我的div的宽度/高度。



• 我忘记了这样做：
  
  

   初始化（）; 
  
  函数initialize（）{
   google.maps.event.addDomListener（window，'load'，function（）{
   codeAddress（'London'）; 
   }）; 
  } 
   

谢谢！

I am trying to load a map from the Google API into a div. However, the map is not loaded, and no errors are outputted. This is the code:

// google maps

var geocoder, map;
function codeAddress(address) {
    geocoder = new google.maps.Geocoder();
    geocoder.geocode( { 'address': address}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
        var myOptions = {
        zoom: 8,
        center: results[0].geometry.location,
        mapTypeId: google.maps.MapTypeId.ROADMAP
        }
        map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);

        var marker = new google.maps.Marker({
            map: map,
            position: results[0].geometry.location
        });
      }
    });
  }


  google.maps.event.addDomListener(window, 'load', function() {
    codeAddress('" . $location['address'] . " " . $location['zip'] . " " . $location['city'] . " " . $countries[$location['country']] . "');
  });

I have been dealing with the problem for quite a long time now, and I am out of ideas.

Anybody of you familiar with the google maps api, who knows what's wrong with my code? My div does exist with the ID: map_canvas.

The problem was:

• I didn't use API-key (even though it don't think this was nessecary, but it worked)
• I didn't set the width/height of my div.

• I forgot to initalize like so:

  initialize();
  
  function initialize() {
    google.maps.event.addDomListener(window, 'load', function() {
      codeAddress('London');
  });
  }
  

It now works. Thanks!
