I have a master layout looking somehow like this
<html>
<head>
...
</head>
<body>
<section data-role="page" data-theme="d">
<section data-role="content">
#RenderBody()
</section>
...
#Scripts.Render("~/bundles/jquery.mobile")
</section>
</body>
</html>
And I have a couple of controllers and templates pushing some code into content section of master layout.
When i click on a link:
Some order
the ajax loader is shown, the url changes, but all I see is the broken markup of the original page. If I inspect the code I will see that there are two page sections in the DOM (which means that the target page is successfully injected but isn't shown).
If I refresh page I will see the target page.
So what's wrong? Why can't I get the fancy JQM page transitions? thank you.
Add the data-ajax='false' on the links who were responsible for redirect you to another page.
JQuery Mobile uses AJAX navigation unless you tell it otherwise. The ASP.NET redirects have no problem to normal requests, but cause issues with AJAX. So my answer in this case is to turn off AJAX. For that, all you have to do is add the attribute data-ajax='false' to the tag.
In my case, an easy solution could be (as changing each Html.ActionLink/Url.Action is time consuming), adding this at the end of the _Layout.cshtml (just before closing of the 'body' tag).
$(document).on('pageinit', function() {
$('a').each(function() {
$(this).attr("data-ajax", "false");
});
});
That would be fine assuming you don't want jQuery mobile to use any Ajax with links too.
You can go ahead and use Ajax in most circumstances and only turn it off selectively where it can cause a problem.

I minimized the problem to this simple reproduction. Create new Asp.net MVC app, add Angular.js via nugget.
_Layout.cshtml:
<head>
<!-- Other stuff -->
#RenderSection("JavascriptInHead", required: false)
</head>
_Index.cshtml
#section JavascriptInHead {
<script src="~/Scripts/angular.min.js"></script>
}
<div ng-app>
{{2 + 2}}
</div>
So this works (obviously), however when I click, say About or Contact menu to reload another view and then go back to Home, I get
{{2 + 2}}
Then I click page reload two times and I get
4
Please help me understand this..
Angular bootstraps when the document loads. So if you are loading html that contains angular into your page without doing a full page refresh, you'll need to bootstrap angular manually. Try adding this script to your partial page:
angular.element(document).ready(function() {
angular.bootstrap(document);
});
btw, I for one appreciate you posting a concise example rather than 100 lines of code from your actual project. If your actual project has an app name, however, like this...
<div ng-app="myApp">
then the js you put into your partial page should look like this...
angular.element(document).ready(function() {
angular.bootstrap(document, ['myApp']);
});
Documentation for manually bootstrapping Angular can be found here: https://docs.angularjs.org/guide/bootstrap
I have a PHP file that generates a JQuery-Mobile page using SQL-Queries:
<!DOCTYPE html>
<html>
<head>
[...]
</head>
<body>
<div data-role="page" id="page1">
[... a listview and a form ...]
</div>
<div data-role="page" id="page2">
[... some stuff ...]
</div>
</body>
</html>
The form has the same PHP file as action that generates the whole page. So, JQuery Mobile will submit the request to this file and refresh the page content (at least theoretically).
When submitting one of these forms, the content of the page get's updated. But after switching between the pages, the new content is lost.
I already tried to disable caching, but this did not work.
Also I read the documentation of jquerymobile, but I do not really understand how this ajax submission works. What should my PHP file return in case of an submission? The entire site?
Cheers
I would keep the form action outside the first file so that code is seperate. You could then submit the form using ajax and make the form action return some sort of JSON data to indicate whether the submit was successful (something like {code : 200, message : "Success"} should do)
I have a "normal" link in my jqm page like this:
<a href="http://www.mysite.com/mobile/page.php?attribute=value">
And if I click it it won't properly refresh taking into account the attribute value and loading everything that's needed for it dynamically based on the attribute value. I understand that this is due to the fact that jqm tries to do an ajax call like mentioned here:
When you use pageChange an Ajax request will be made to that url and it will be
loaded only the content inside the div with data-role="page". So everything you
have out of this element will be ignored (JS and CSS).
So, I found out in the docs that I should use $.mobile.ajaxEnabled=false; or rel=external on links or target=_blank on the link.
Strange thing though for me is that only when I set the target=_blank property to my links will this truly happen. So, am wondering if someone had this kind of a problem and how did you solve it? The thing is, I would like to refrain myself form using target=_blank as it opens a new tab in my browser (as expected, but this is not nice from users' POV).
jqm version I use is 1.2
This question now at the top of google search results, so figured I'd answer:
Use the data-ajax attribute and set it to false to force reload upon clicking a link:
data-ajax="false"
use it like:
<a href="/" data-ajax="false">
<img id="mainLogo" src="logo.svg" width="215" />
</a>
And then your link will force reload the page!
Linking without Ajax
Links that point to other domains or that have rel="external",
data-ajax="false" or target attributes will not be loaded with Ajax.
Instead, these links will cause a full page refresh with no animated
transition. Both attributes (rel="external" and data-ajax="false")
have the same effect, but a different semantic meaning: rel="external"
should be used when linking to another site or domain, while
data-ajax="false" is useful for simply opting a page within your
domain from being loaded via Ajax. Because of security restrictions,
the framework always opts links to external domains out of the Ajax
behavior.

Make function for the onclick event of the link.See the below code example.Hope this helps!
<script type="text/javascript">
function loadPage(url){
document.location.href = url;
}
<script/>
<a href="#" onClick="loadPage('http://www.mysite.com/mobile/page.php?attribute=value');">
Have the following markup in my html page to toggle a search bar based on if a search icon is clicked:
<a id="searchIcon" href="/"></a>
<div id="searchWrapOuter" style="display:none;">
<div id="searchWrapInner">
<div id="formContainer">
<form id="searchForm" action="#">
<div>
<input type="search" name="search-mini" id="search-mini" value="" data-mini="true" />
</div>
</form>
</div>
</div>
</div>
Width the following javascipt/jquery:
$(function() {
$(document).on("click", "#searchIcon", function () {
var searchWrapper = $("#searchWrapOuter");
$(searchWrapper).slideToggle();
return false;
});
});
This code works as expected on a page load direct off a Url. When coming into the page off a link which is Ajax loaded, loads the contents of the page into the DOM, and the DOM ready handler only executes for the first page.
I have read about using the
$(document).on('pageinit'), not $(document).ready()/$(function()
I still haven't been able to get this to work when coming in off an ajax link however. What would be the correct way to implement these events to get the code to work coming in from an Ajax link?
Thanks,
Most likely it is because you are using IDs instead of classes. jQuery Mobile doesn't work well with IDs because it caches pages into the DOM so if you open a page, close it, then go back to the page, you might have your page twice inside the DOM (one visible, one hidden/cached). So when you do $("#searchWrapOuter") you don't know which element you are actually dealing with (in your case, probably the hidden one).
The solution is to change your IDs to classes. This is not very intuitive but I found that is the best way to work with jQuery Mobile.
Also note this comment in the doc which might also be relevant to you:
The id attribute of all your elements must be not only unique on a given page, but also unique across the pages in a site. This is because jQuery Mobile's single-page navigation model allows many different "pages" to be present in the DOM at the same time. This also applies when using a multi-page template, since all "pages" on the template are loaded at once.
http://jquerymobile.com/demos/1.2.0/docs/pages/page-anatomy.html
You can manually adjust delay time to 500ms and 1s.
$(searchWrapper).delay(1000).slideToggle();
My issue is that the page id was below the pages tags. So once I moved the page div above it, the javascript was included in the ajax page load. Previous to this
I have Jquery Mobile working and have found the best way to get it to work is by including it in the /client/ directory. So, I have the following files in my /client/ directory
jquery.js
jquery-mobile.js
jquery-mobile.css
Then I include this in my index.html
<script type="text/javascript">
$( document ).bind( "mobileinit", function( event, data ){
$.mobile.autoInitializePage = false;
}
</script>
I tried creating a smart package but then the loading order invalidated jquery plugins for some reason. I tried just using references in the HEAD but that do invalidated jquery plug ins for some reason. The above works, pages transition, views render and I can even use the Meteor auth branch and render subscriptions.
The problem I am having now is when Meteor updates the DOM with data and renders the data it is not rendered with JQM.
For example, if I try to use a JQM Listview to display a Meteor subscription it just formats like a regular un-ordered list .
Here is the template code.
{{#each get_groups}}
<ul data-role="listview" data-theme="a">
<li>{{name}}</li>
</ul>
{{/each}}
Which just renders as bulleted items. If I use static data like the JQM tuts show it renders fine.
<ul data-role="listview" data-theme="a">
<li>Acura</li>
<li>Audi</li>
<li>BMW</li>
</ul>
I am suspect I may need to call some kind of refresh, which means I would have to use observe on the collection subscriptions I imagine.
I am having the same problem with a custom login button. I use a template helper to return the Meteor.user().username and the button doesn't get formatted by JQM. If I don't use return the username the button of course renders find through JQM.
I also have the same problem when I try to access the Handlebars current user. If I try to do the following the publicPage will load.
{{#if currentUser}}
{{>privatePage}}
{{else}}
{{>publicPage}}
{{/if}}
Once I login the privatePage flickers quickly and then just a white screen. If I remove the references to currentUser then I can login and use the JQM changePage method to load the privatePage.
$.mobile.changePage("#privatePage");
I only have a rough understanding but I believe it is related to how and when JQM formats data for rendering vs. how and when Meteor formats data for rendering.
Does anyone has any ideas on how I might get JQM to behave nicely with Meteor? or if I should even bother and maybe use another mobile front end alongside Meteor?
Thanks

You do have to refresh when data changes. Here's a full sample app with Meteor and JQM:
http://jqm.meteor.com/
Source code here:
https://github.com/snez/jqm-meteor
Notice on lines 17 and 38 that when an element is rendered, you have to refresh it and rebind any custom events to it.
