I have a multiple page jquery mobile app (along with Phonegap). In one of the dynamically loaded pages, I am trying to use iScroll (v5) to let the users scroll through a large image, both horizontally and vertically. Here is the code I am using for this page:
!DOCTYPE HTML>
<html>
<head>
<title>Title</title>
</head>
<body>
<div id="largeimage-viewer" data-role="page" class="backdrop">
<script type="text/javascript" charset="utf-8" src="../common/iscroll.js"></script>
<script type="text/javascript" charset="utf-8">
$("#largeimage-viewer").die('pageinit');
$("#largeimage-viewer").live('pageinit', function (e)
{
var myscroll = new IScroll(document.getElementById('wrapper'),
{
scrollbars: true,
scrollX: true
//freeScroll: true,
//fadeScrollbars: true
});
console.log("Created iScroll object: " + (myscroll != null));
});
</script>
<div data-role="header">
Back
<center>CG</center>
</div><!-- /header -->
<div data-role="content" style="scrolling: scroll">
<div id="wrapper">
<img alt="Floor Plan" src="../common/images/floorplan.jpg" width="1217" height="1699" />
</div>
</div><!-- /content -->
</div><!-- /page -->
</body>
</html>
When I view the page on my Android (4.1.2), the image shows up but I can't scroll the image at all. There is no scrollbars visible either.
Can anyone suggest what I might be missing? Thanks.
Earlier, I tried the following without using iScroll library:
<div data-role="content" style="scrolling: scroll">
<div style="-webkit-overflow-scrolling: touch; overflow: scroll;">
<img alt="" src="../common/images/floorplan.jpg" />
</div>
</div><!-- /content -->
This code showed the vertical scrollbar, and scrolling worked alright, but the horizontal scrolling was extremely slow and there was no scrollbar either. With all the swiping across the screen, I would get the image moved horizontally by one inch or so!! Any solution on this front would also be appreciated.

allowSamePageTransition: true,
transition: 'none',

It can be work if i run page2 individually. But problem come once i change page from page1 to page2. please dont reply me add rel="external" It may cause white screen issue once i using rel="external"
This is a known jQuery Mobile 1.4 bug, it will be fixed in jQuery Mobile 1.4.3 version.
Read more about it here: https://github.com/jquery/jquery-mobile/issues/7169
There you will also find a workaround.
There's one other solution, it requires you to dynamically create tab widget, something like this:
$(document).on("pagecreate", "#p2", function () {
var tabs = '<div data-role="tabs" id="tbPaymentMethod"><div data-role="navbar"><ul><li>Tab 1</li><li>Tab 2</li><li>Tab 3</li></ul></div><div id="tabCash"><p>This is the content of the tabwith the id fragment-1.</p></div><div id="tabCcard"><p>This is the content of the tabwith the id fragment-2.</p></div><div id="tabCheck"><p>This is the content of the tabwith the id fragment-3.</p></div></div>';
$("#p2 .ui-content").append(tabs).enhanceWithin();
});

I'm trying to understand how $.mobile.changePage works. I placed the method $.mobile.changePage in an anonymous function after the last element in the DOM and it didnt work but if I was to place it in document.ready it works fine. How come? any advice much appreciated

<p>View internal page called bar</p>

<div data-role="footer">

<!-- Start of second page -->
<div data-role="page" id="bar">
<div data-role="header">

</div><!-- /header -->
<div data-role="content">
<p>I'm the second in the source order so I'm hidden when the page loads. I'm just shown if a link that references my id is beeing clicked.</p>
<p>Back to foo</p>
</div><!-- /content -->
<div data-role="footer">
<h4>Page Footer</h4>
</div><!-- /footer -->
</div><!-- /page -->
<script>
(function(){
$.mobile.changePage($("#bar"), { transition: "slideup"} );
})();// this doesn't work
$(document).ready(function(){
$.mobile.changePage($("#bar"), { transition: "slideup"} );
})//this works
</script>
document ready dont work correctly with jQuery Mobile. Usually it will trigger before pages are loaded inside the DOM.
If you want to find more about this take a look at this ARTICLE, to be transparent it is my personal blog. Or find it HERE.
To make it work you need to use correct page event, like this:
$(document).on('pagebeforeshow', '#foo', function(){
$.mobile.changePage($("#bar"), { transition: "slideup"} );
});
At the same time this is not a good solution. You should not change page while first page is loading, mainly because it will cause jQuery Mobile to misbehave. Ether do it after first page is successfully loaded (page #foo) or change page order and let page #bar be the first page.
I would like my header and footer to be accessible when a page has an overlay due to a popup menu (as seen on http://jquerymobile.com/branches/popup-widget/docs/pages/popup/index.html).
So in a nutshell, only the div with attribute 'data-role=content"' should have the overlay applied.
If possible, this should be achieved using a minimum of extra CSS and/or JavaScript. I've looked through the entire jQuery Mobile docs, but haven't found any reference to my problem.
Some code:
<!DOCTYPE html>
<html>
<head>
<title>Context Menu</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://jquerymobile.com/test/css/themes/default/jquery.mobile.css" />
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://jquerymobile.com/test/js/jquery.mobile.js"></script>
</head>
<body>
<div data-role="page">
<div data-role="header" data-position="fixed">
<h1>Header</h1>
</div>
<div data-role="content">
Menu
<div data-role="popup" id="popupMenu" data-overlay-theme="b">
<ul data-role="listview" data-inset="true" style="width: 200px">
<li>Add</li>
<li>Edit</li>
<li>Manage</li>
<li>Delete</li>
</ul>
</div>
</div>
<div data-role="footer" data-position="fixed">
<h1>Footer</h1>
</div>
</div>
</body>
</html>
So in this exmaple, the header and footer shouldn't be overlayed when the Menu link is clicked.
The z-index css property allows you to set the way the different "layers" of your page are superposed. A fixed header in jquery mobile has a z-index of 1000.
By setting the z-index of your overlay to a value below 1000, it will be displayed "under" the header.
I've developed an app for ios and android using phonegap. It's a dictionary app and it will display result in multiple tab (the tab is a div, every div will display different content). I use my own code so that only one div is shown at any time. Now I want to include jquerymobile so that I can apply a animation/transition when switching to other div.
So I add the data-role="page" to each div, which I assume will work immediately(like sample code below). But something is not right.
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.css" />
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.js"></script>
</head>
<body>
<table id="headergroup">
<tr><td>
<input>.........
<img>.......
</table>
<wrapper>
<div data-role="page" id="tab1">
<div data-role="header">
<h1>Page Title</h1>
</div>
<div data-role="content">
<p>Page1 content goes here.</p>
</div>
<div data-role="footer">
<h4>Page Footer</h4>
</div>
</div>
.........other div......
<div data-role="page" id="tabN">
<div data-role="header">
<h1>Page Title</h1>
</div>
<div data-role="content">
<p>PageN content goes here.</p>
</div>
<div data-role="footer">
<h4>Page Footer</h4>
</div>
</div>
</wrapper>
<div id="footer>
<img .......>
</div>
</body>
</html>
Supposely, my app should display the div(s) in the wrapper only. But the problem is, now my app will display the div with data-role=page in full screen and on top of other element (my app header and footer were not shown).
Is my implementation correct? How do I overcome this problem? Thanks.
You may get by with this on the first page, but on all other pages you are loading in via JQM-Ajax (default), you will only grab what's inside your first(!) div-data-role="page" from the page you are loading. Everything else (table, 2nd, 3rd page-div will not be loaded, because it's outside the page-div.
Have a look at the JQM docs on page anatomy and linking pages.
JQM is based on page-divs, so also in your code the page-div will get most "JQM attention" being set to fullscreen size and of cource hovering above everything else.
To use JQM you will either go with
Single page layout = page by page
Multi pape layout = multiple pages contained in one document.
Since you are using Phonegap, which I think bundles everything into a single file eventually, you may be better off with multipage. There is also a subpage widget or multiview, if you need to load documents with multiple "nested pages" from your initial page.
When calling changePage() with changeHash = false, the location bar does not change.
Can I have identical behavior with anchor links (e.g. Blah)? I set $.mobile.hashListeningEnabled = false, but the location bar is still updated.
Thanks for the help.
This can be done by setting $.mobile.changePage.defaults.changeHash = false;
Sample code :
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script>
$(document).bind("mobileinit", function(){
$.mobile.changePage.defaults.changeHash = false;
});
</script>
<script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>
</head>
<body>
<div data-role="page">
<div data-role="header">
<h1>Page Title</h1>
</div><!-- /header -->
<div data-role="content">
<a data-role="button" href="#page2">Go to page2</a>
</div><!-- /content -->
</div><!-- /page -->
<div data-role="page" id="page2">
<div data-role="header">
<h1>Page Title</h1>
</div><!-- /header -->
<div data-role="content">
<p>Page content goes here.</p>
</div><!-- /content -->
</div><!-- /page -->
</body>
</html>
figured I'd answer this with a nifty block of code that you can put BEFORE you load jquery mobile AFTER you load jquery, adds the extra attribute 'data-change-hash' to any link tag so that the location does not change
$('a[data-change-hash="false"]').on('click',function(e) {
$.mobile.changePage($(this).attr('href'),{'changeHash':false});
e.preventDefault();
});
will enable you to do this
Test Me!
and your url will stay like http://example.com instead of changing to http://example.com#my-page
try it out: it works for me in jQM 1.4.5
$.mobile.hashListeningEnabled = false;
When applied then page changes does not alter the browser's address bar anymore, in the same way when using explicit calls to:
$.mobile.pageContainer.pagecontainer("change","tosomewhere.html",{ changeHash: false });
Although I like Chad Brown's solution for this, I went with a much simpler and easier to grasp approach specially for people new to jquery.
so I start by creating a function script and can be placed anywhere with in your code, doesn't need to be in a specific handler or callback.
<script>
function goTo(pageID,track){
$.mobile.pageContainer.pagecontainer('change','#'+pageID, {changeHash: track});
}
</script>
and then in my anchor tags I will do just call the function just like this
