Question

I was testing out this demo on query-ui-maps: http://jquery-ui-map.googlecode.com/svn/trunk/demos/jquery-google-maps-mobile.html#directions_map

Everything is the same except for the head section of my index.html file:

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1,  user-scalable=no">
        <link rel="stylesheet" href="jquery-mobile/jquery.mobile.css" />
        <link href="css/jquery.mobile-swatch.css" rel="stylesheet" type="text/css"/>
        <link href="css/custom-icons.css" rel="stylesheet" type="text/css"/>
        <link href="css/mapapp.css" rel="stylesheet" type="text/css"/>
        <script src="http://maps.google.com/maps/api/js?sensor=false&libraries=places"  type="text/javascript"></script>
        <script src="js/jquery.js"></script>
        <script src="jquery-mobile/jquery.mobile.js"></script>
        <script type="text/javascript" src="ui/jquery.ui.map.js"></script>

<script type="text/javascript" src="js/modernizr.js"></script>
        <script type="text/javascript" src="js/demo.js"></script>

The demo works in safari on my desktop but loads the screen attached whether I test in an ios5 simulator or an ios5 phone. No errors are logged to the console. I am testing in Xcode and using phone gap. Blank screen Please help.

This is the code:

var mobileDemo = { 'center': '57.7973333,12.0502107', 'zoom': 10 };
        $('#directions_map').live('pageinit', function() {
            demo.add('directions_map', function() {
                $('#map_canvas_1').gmap({'center': mobileDemo.center, 'zoom': mobileDemo.zoom, 'disableDefaultUI':true, 'callback': function() {
                    var self = this;
                    self.set('getCurrentPosition', function() {
                        self.refresh();
                        self.getCurrentPosition( function(position, status) {
                            if ( status === 'OK' ) {
                                var latlng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude)
                                self.get('map').panTo(latlng);
                                self.search({ 'location': latlng }, function(results, status) {
                                    if ( status === 'OK' ) {
                                        $('#from').val(results[0].formatted_address);
                                    }
                                });
                            } else {
                                alert('Unable to get current position');
                            }
                        });
                    });
                    $('#submit').click(function() {
                        self.displayDirections({ 'origin': $('#from').val(), 'destination': $('#to').val(), 'travelMode': google.maps.DirectionsTravelMode.DRIVING }, { 'panel': document.getElementById('directions')}, function(response, status) {
                            ( status === 'OK' ) ? $('#results').show() : $('#results').hide();
                        });
                        return false;
                    });
                }});
}).load('directions_map');

        });


        $('#directions_map').live('pageshow', function() {
            demo.add('directions_map', $('#map_canvas_1').gmap('get', 'getCurrentPosition')).load('directions_map');
        });

    </script>
