Menu
I am developing an iPhone application using PhoneGap and jQueryMobile, in my application I have two html pages, first is index.html page and second is mapView.html, now, my problem is when I open mapView.html from index.html using
function loadMap() {
$.mobile.changePage( "mapView.html", { transition: "pop"} );
}
map is not loading. If I open mapView.html on any browser it works perfectly, even if I load mapView.html directly by changing
self.viewController.startPage = @"mapView.html";
in appDelegate class map loads on screen. Do anyone have any idea why map is not loading when I open it from another .html page?My PhoneGap version is 2.0.0
Thanks.
EDIT 1:mapView.html code

The $.mobile.changePage uses the jQuery Mobile AJAX functionality. jQuery Mobile loads only the code which is inside the first data-role="page" element in the DOM.
As stated in the jQuery Mobile docs , in jQuery Mobile, AJAX is used to load the contents of each page into the DOM as you navigate, and the DOM ready handler
$(document).ready()only executes for the first page.
Below you can find a working example which includes two pages, the navigation is performed through Ajax and the map is loaded inside the second page:
Also note that you can perform a transition using rel="external" or data-ajax="false". The usage of these attributes will cause a full page refresh without animated transition.
Working Example:
Instructions:
Add the below code inside the maps.js:
function initialize() {
var mapCenter = new google.maps.LatLng(59.3426606750, 18.0736160278),
myOptions = {
zoom:10,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: mapCenter
},
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}
$( document ).on( 'pageshow', '#map-page',function(event){
initialize();
});
$( document ).on( 'click', '#map-anchor', function(event){
event.preventDefault();
$.mobile.changePage( "map.html", { transition: "flip" } );
});
Add the below code inside the map-intro.html:
<!doctype html>
<html lang="en">
<head>
<title>Map Intro Page</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.css" />
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.js"></script>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?v=3&sensor=false&language=en"></script>
<script src="./maps.js"></script>
</head>
<body>
<div id="map-intro-page" data-role="page">
<div data-role="header">
<h1><a data-ajax="false" href="/">Map Example</a></h1>
</div>
<div data-role="content">
<ul data-role="listview" id="my-list">
<li><a href="#" id="map-anchor">Go to Map</a></li>
</ul>
</div>
</div>
</body>
</html>
Add the below code inside the map.html:
<!DOCTYPE html>
<html>
<head>
<title>jQuery mobile with Google maps geo directions example</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.css" />
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.js"></script>
</head>
<body>
<!-- /page -->
<div data-role="page" id="map-page">
<!-- /header -->
<div data-role="header">
<h1>Map</h1>
<a data-rel="back">Back</a>
</div>
<!-- /content -->
<div data-role="content" class="ui-bar-c ui-corner-all ui-shadow" style="padding:1em;">
<div id="map_canvas" style="height:300px;"></div>
</div>
</div>
</body>
</html>
I hope this helps.
