Question

I have the following script. And I want to make both maps appear on the page, but no matter what I try I can only get the first map initialize() to display… the second one doesn’t. Any suggestions? (also, I can’t add it in the code, but the first map is being displayed in <div id="map_canvas"></div><div id="route"></div>
Thanks!

<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>

Here is how I have been able to generate multiple maps on the same page using Google Map API V3. Kindly note that this is an off the cuff code that addresses the issue above.

The HTML bit

<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>

Javascript for map initialization

<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>
