jQuery Mobile - How to implement Google Maps on Externally Linked Pages
I am attempting to use Google Maps API 3 with jQuery Mobile and cannot get my external pages to load a map. I checked in Firebug and it appears that the map is being created but is hidden on the page. I can get the home page to load a map successfully and I can get external pages to load the map successfully using rel="external" attribute on the link. But for external pages not using rel="external" the map doesn't show up.
Here is my code:
index.html
<!DOCTYPE html>
<html>
<head>
<title>Index</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0a2/jquery.mobile-1.0a2.min.css" />
<script src="http://code.jquery.com/jquery-1.4.4.min.js"></script>
<script src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script src="http://code.jquery.com/mobile/1.0a2/jquery.mobile-1.0a2.min.js"></script>
</head>
<body>
<div data-role="page">
<div data-role="header">
<h1>jQuery Mobile</h1>
</div>
<div data-role="content">
<ul data-role='listview' id='menu'>

How can I get a Google Map to show up on an external page without using rel="external"?
I found the solution. I needed to initialize the Google map in the "pagecreate" jQuery Mobile event instead of on $(document).ready. I also had a problem with the full map not rendering properly everytime the page showed so I solved that by calling google.maps.event.trigger(map, 'resize') to refresh the map on the "pageshow" jQuery Mobile event.
Here is my code:
index.html
<!DOCTYPE html>
<html>
<head>
<title>Index</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0a2/jquery.mobile-1.0a2.min.css" />
<script src="http://code.jquery.com/jquery-1.4.4.min.js"></script>
<script src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script src="http://code.jquery.com/mobile/1.0a2/jquery.mobile-1.0a2.min.js"></script>
<style type="text/css">
.gmap { height: 330px; width: 100%; margin: 0px; padding: 0px }
</style>
</head>
<body>
<div data-role="page">
<div data-role="header">
<h1>jQuery Mobile</h1>
</div>
<div data-role="content">
<ul data-role='listview' id='menu'>
<li><a href="pages/map1.html">external map page 1</a></li>
<li><a href="pages/map2.html">external map page 2</a></li>
</ul>
</div>
</div>
</body>

map1.html
<div data-role="page" class="page-map1">
<div data-role="header">
<h1>jQuery Mobile</h1>
</div>
<div data-role="content">
<h2>Map</h2>
<div id="map1" class="gmap"></div>
<script type="text/javascript">
var map1, latlng1, options1;
function initialize() {
latlng1 = new google.maps.LatLng(40.716948, -74.003563);
options1 = { zoom: 14, center: latlng1, mapTypeId: google.maps.MapTypeId.ROADMAP };
map1 = new google.maps.Map(document.getElementById("map1"), options1);
}
$('.page-map1').live("pagecreate", function() {
initialize();
});
$('.page-map1').live('pageshow',function(){
//console.log("test");
google.maps.event.trigger(map1, 'resize');
map1.setOptions(options1);
});
</script>
</div>
</div>
map2.html
<div data-role="page" class="page-map2">
<div data-role="header">

</div>
<div data-role="content">

<div id="map2" class="gmap"></div>
<script type="text/javascript">
var map2, latlng2, options2;

options2 = { zoom: 14, center: latlng2, mapTypeId: google.maps.MapTypeId.ROADMAP };
map2 = new google.maps.Map(document.getElementById("map2"), options2);
}
$('.page-map2').live("pagecreate", function() {
initialize();
});
$('.page-map2').live('pageshow',function(){
google.maps.event.trigger(map2, 'resize');
map2.setOptions(options2);
});
</script>
