如何使用API​​ V3在每个页面上显示多个Google Maps

javascript

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>

这就是我使用能够在同一页面上生成多个地图的方式Google Map API V3。请注意,这是解决上述问题的现成代码。

HTML位

<div id="map_canvas" style="width:700px; height:500px; margin-left:80px;"></div>
<div id="map_canvas2" style="width:700px; height:500px; margin-left:80px;"></div>

地图初始化的Javascript

<script type="text/javascript">
var map, map2;

function initialize(condition) {
    // create the maps
    var myOptions = {
        zoom: 14,
        center: new google.maps.LatLng(0.0, 0.0),
        mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

    map2 = new google.maps.Map(document.getElementById("map_canvas2"), myOptions);
}
</script>
