There are several ways to force an external load (data-ajax="false", rel="external"), but what if I have an external link that will serve me a jquery mobile page and I want it to load via ajax with transitions (without the page reloading)? Anyone have a straightforward solution?
The reason I'm asking is that I'm building a PhoneGap IOS app and the index.html file is no longer on the same path as the pages that are being fetched.
Thanks
You can use framework such as jQTouch or jQuery Mobile. These frameworks have built in functions which can help you in call cross domain AJAX calls with in the application it self.
For example:
$.get("test.php",
{ name: "micky", time: "2pm" },
function(data){
alert("Data Loaded: " + data);
}
);
See demo here: http://jqtouch.com/preview/demos/ but make sure to use web kit enabled browsers such as Chrome/Safari.

How to change between pages using Jquery Mobile in Worklight
(1 answer)
Closed 8 years ago.
I am developing a sample mobile banking app in IBM Worklight V6.2 using the jQuery Mobile Framework. I read the Getting Started Documentation on IBM Worklight and it mentions a way to implement multi-page navigation using fragments. However, it also states that if you are using a JavaScript UI Framework, use its API's instead.
I read up on the jQuery Mobile pagecontainer method and am implementing it as below:
<li>Branch Locations</li>
However, I get the issue that the linked page loads after clicking the link but the original page then reloads. Could someone explain to me why this is happening? Is this a known issue?
I found the problem. I had a link to the
<script src="jqueryMobile/jquery.mobile-1.4.3.js"></script>
In the linked pages. That is the reason it was reinitializing the original index page.
See this project for a Worklight 6.2-based app using jQuery Mobile 1.4.3's Pagecontainer widget.
In the app, you click on a button to transition from index.html to page1.html by using:
HTML
load page1
JavaScript
function changeToPage1() {
$(':mobile-pagecontainer').pagecontainer('change','page1.html');
}
You may also take a look at the following questions that are answered with explanation and project examples for using changePage.
Note that the projects may be from Worklight 6.0 and 6.1 rather than 6.2 but that does not matter as here it's about the JavaScript, simply review it.

In all of them, the idea is that Worklight is a Single Page Application. Thus you cannot load another HTML file and expect the application to continue functioning. By doing so you lose the "context" of the Worklight framework - the references to the included JS files, etc.
Instead, you can use jQuery's load or jQuery Mobile's changePage (deprecated in v1.4, to be removed in v5), to load different "pages". Ample examples are provided above.
I've got a website that I'm converting into an app using JQM. I've read about Pages and how the DOM loads but I'm still uncertain how to architect the site.
The main page of the application is based on the Google Maps API which uses JS to load. There are 150+ target pages so I don't want them to load until the user taps the link. All of the target pages also require JS to initialize. When they return to the main page the cached state should be the default but I also need the option to run JS if the query string changes. Content doesn't change often so my preference would be to cache data once loaded but there would need to be some way to flush the cache.
I converted the site to JQM. The target page JS didn't run so I added rel='external' to the links. The JS now runs on the target but when I link back to the main page it reloads the page without running initializing the JS. The obvious solution would be to add rel="external" but then I'd be defeating all performance value. Any recommendations on how I should structure it?
Using rel=external your links will not be loaded with Ajax and you will lose animated page transitions. If you want to run some script when a page displays, use this page event:
$(document).on("pageshow", "#selector", function(event, ui) { /* your code */ });
This and other useful events are described in jQuery Mobile API Documentation.
For example, pagecreate (the now deprecated pageinit) is called once when the page initializes.
About getting query string parameters, see this answer.
We encounter the following problems with Jquery Mobile.
Our site is divided in a mobile and a fixed desktop site.
Both use the same database and php code. Only the templates are different.
On our mobile site we use Jquery mobile for a better user experience and that works fine. However we integrated a button "goto desktop".
This link should bring us back to our "normal" desktop site.
But there is the problem. In the desktop-site, Jquery mobile is still activated and it replaces drop down fields, input fields and make a complete mess of the desktop site.
We tried everything to disable JQM but nothing seems to work.
How we can switch from our mobile site template to the desktop site template and disable JQM completely when we are on the desktop template?
Thanks a lot for help!
There are few available solutions but only one will really do.
Working example: http://jsfiddle.net/Gajotres/NvEcW/
Few things are needed, first we need to set this:
<script>
$(document).on('mobileinit', function () {
$.mobile.ignoreContentEnabled = true;
});
</script>
it will give us an ability to programatically turn on/off content enhancement. If you already don't know this mobileinit event must be initialized before jQuery Mobile initialization but after the jQuery initialization. This must always be a part of a page.
There's one last step. When we want to move from mobile to desktop page we need to reload page and use this javascript:
$(document).on('pagebeforecreate', '#index', function(){
$(this).attr('data-enhance','false');
});
Pagebeforecreate event is important because at this point content is still not enhanced and attribute data-enhance = false will prevent any further page enhancement. If you want to turn it on again just set attribute value to true.
If you want more solutions then take a look at my other answer, search for the topic Methods of markup enhancement prevention : jQuery Mobile: Markup Enhancement of dynamically added content.
After loading up a Webclip with some links in it, clicking a link launches Mobile Safari instead of loading the link in the same window. Is there a way to prevent the link loading in Safari instead of the Webclip instance? I'm trying to mock up a mobile app just using PHP on my local Apache installation.
According to the Apple docs it looks like external page links will always open in Mobile Safari:
In this mode any external links will be opened in Safari on
iPhone, meaning that you will have to keep your web application to a
single page and use Ajax to update parts of that page.
In addition to the option of using a single page loading new content with AJAX, you can use the JavaScript self.location=URL; return false on hyperlinks that must stay within the application. This can be added to the HTML code directly, or with another script upon loading the page.
If you are using jQuery, I would recommend something like this:
$('a:not([target])').click(function(){
self.location = $(this).attr('href');
return false;
});
Obviously this script should be ran after the HTML has loaded, to ensure that it actually attaches to the A elements onClick event.
I know that phonegap does not provide any server communication functionality, I would like to ask any open source framework can do that?If I used jquery-mobile,I won't use phonegap function. because AJAX doesn't work when using phonegap.
you can use Jquery JS file along with jquery-mobile and phonegap . this will let you make AJAX calls
