我有以下脚本。而且我想使两个地图都显示在页面上，但是无论我怎样尝试，我都只能使第一个地图显示initialize（），而第二个地图则没有。有什么建议么？（而且，我无法在代码中添加它，但是在“
<div id="map_canvas"></div><div id="route"></div> 感谢” 中显示了第一张地图！

<script type="text/javascript"> 
// Create a directions object and register a map and DIV to hold the 
// resulting computed directions

var map;
var directionsPanel;
var directions;

function initialize() {
  map = new GMap(document.getElementById("map_canvas"));
  map.setCenter(new GLatLng(41.1255275,-73.6964801), 15);
  directionsPanel = document.getElementById("route");
  directions = new GDirections(map, directionsPanel);
  directions.load("from: Armonk Fire Department, Armonk NY to: <?php echo $LastCallGoogleAddress;?> ");

  map.addControl(new GSmallMapControl());
  map.addControl(new GMapTypeControl());
}

</script>


<div id="map_canvas2" style="width:200px; height:200px;"></div>
<div id="route2"></div>

<script type="text/javascript"> 
// Create a directions object and register a map and DIV to hold the 
// resulting computed directions

var map2;
var directionsPanel2;
var directions2;

function initialize2() {
  map2 = new GMap(document.getElementById("map_canvas2"));
  map2.setCenter(new GLatLng(41.1255275,-73.6964801), 15);
  directionsPanel2 = document.getElementById("route2");
  directions2 = new GDirections(map2, directionsPanel2);
  directions2.load("from: ADDRESS1 to: ADDRESS2 ");

  map2.addControl(new GSmallMapControl());
  map2.addControl(new GMapTypeControl());
}

</script>

<script type="text/javascript">
function loadmaps(){
    initialize();
    initialize2();  
}
</script>
