I have a phonegap/jquerymobile app that I can't seem to get pagecontainer #change to work for. I have tried the most up to date syntax I could find, but seem to be missing something.
function goToCards() {
console.log('got to goToCards');
$(':mobile-pagecontainer').pagecontainer('change', '#cardsPage');
}

When I run the app in xcode I successfully log 'got to goToCards'. However, there is no page change or any error. A normal non-js function link works to transition the page. Any ideas?
The pagecontainer widget and its methods were introduced in jQuery Mobile version 1.4. You appear to be using a really old version (1.0). Can you upgrade both jQuery and jQuery Mobile versions?
If not, you need to use $.mobile.changePage : API DOC

I am making a checklist app with Phonegap but it debugs in a browser too as they both use web technologies. Anyway, I am having a problem with using the HTML 5 local storage. Perhaps my code is broken, or I am using it wrong. When ever I refresh the page or exit out/come back the data is gone.
Appreciate any help :^)
I tested it on my live domain as well as locally but both do not work.

As was said - the data is persisted and saved correctly.
However the logic is incorrect and overrides all the elements in the localStorage (first element overrides the first, second overrides the first two, third overrides the first three, etc.). Perhaps this is what masks the issue? :)
To be frank, I don't the the logic of running in loop and overriding all existing with the last item (and writing it to the list on the screen each time)...
I'm currently working on an application in cordova. Since I have more pages I tried to add a menu. On the first page (index.html) there is some output, on the second file (settings.html) I want to make a Ajax-Request to a external server.
In the <head>-Tag all stylesheets and jQuery and Cordova is included. In the <body>-Tag some Ajax-calls are made.

If I hit Settings I get to the html-page and the code will be displayed, but the code jQuery/js-code will not be executed. (I tried an alert, but it's not working)
Can you tell me what possibilities I have to include another page with working js-code?
Thanks!
If you are using jQuery Mobile , you can use Single Page Application(SPA) for multiple pages in Cordova like this.

});
$(document).on("pagebeforeshow","#setting",function(){

</script>
<html>
Demo
You need to include a script that will fire when the page is fully loaded into the DOM.
<script>
$(document).ready(function(){
-- call your$.ajax({}) here --
});
</script>
OR
<script>
(function(){
call your $.ajax({}) here --
}();
</script>
Best regards,
I have tried several websocket plugins, but none worked for me.
I can't know what's wrong because when I try the code in a browser, it works successfully but after building the apk, nothing happens.
I have checked the configuration of config.xml, permissions and plugins.
me guess that Jelly beans inbrowser doesn't support websocket (we already know that) but even within the plugins? just a guess.
I am using jwebsocket as a websocket server.
cordova version 3.5.0
please tell me what is the wrong in my code

Under BuildCOnfig.groovy i added the following
plugins {
...
runtime ":twitter-bootstrap:3.0.3"
...
}
Thereafter, i edited my index.html code to like like follows (I found this code example from bootstrap itself).

First, you should upgrade your version of the plugin to 3.1.1:
plugins {
...
compile ":twitter-bootstrap:3.1.1"
...
}
Second, since you are using the bootstrap plugin for Grails you need to use the resource modules to include it. Also you don't need to manually include jQuery as it will be included by the plugin. Here is a simple example of a starter template which is setup correctly for the bootstrap plugin and Grails.

I highly recommend you read up about the resource tag to get an understanding of how to include assets like CSS. It's also worth noting that the documentation for the plugin explains all of the above.
I'm building an app in html/css/javascript and using phonegap to build.
So, I first wanted to have to simple page to page navigation. I tryed this:
index:
<!DOCTYPE HTML>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="jquery.mobile-1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="jquery-1.8.2.js"></script>
<script src="jquery.mobile-1.2.0/jquery.mobile-1.2.0.js"></script>
</head>
<body id="body">
<div id="container" data-role="page">
<a rel="external" data-role="button" href="test.html" data-transition="slide">click me</a>
</div>
</body>
</html>
test.html:
<!DOCTYPE HTML>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="jquery.mobile-1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="jquery-1.8.2.js"></script>
<script src="jquery.mobile-1.2.0/jquery.mobile-1.2.0.js"></script>
</head>
<body id="body">
<div id="container" data-role="page">
New page!
</div>
</body>
</html>
Result: when I click on the button the test.html page loads very slow and the data-transition="slide" seems to be ignored.
I found an article about dynamic page loading: https://www.ibm.com/developerworks/mydeveloperworks/blogs/94e7fded-7162-445e-8ceb-97a2140866a9/entry/dynamic_page_loading_for_phonegap1?lang=en
Which I really don't get. Aren't the HTML files stored locally? So why do a XMLHtppRequest?
My question is: How do I get a good page transition (fast and with effects)?
You should remove rel="external" from your <a> link.
The attribute rel="external" disables the Ajax navigation, skipping the transition effect, and refreshes your page test.html.
Try your code after removing it.
index.html:
<!DOCTYPE HTML>

<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="jquery.mobile-1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="jquery-1.8.2.js"></script>
<script src="jquery.mobile-1.2.0/jquery.mobile-1.2.0.js"></script>
</head>
<body id="body">
<div id="container" data-role="page">
<!-- REMOVE THE ATTRIBUTE REL="EXTERNAL" FROM THE LINK -->
<a data-role="button" href="test.html" data-transition="slide">click me</a>
</div>
</body>
</html>
test.html:
<!DOCTYPE HTML>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="jquery.mobile-1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="jquery-1.8.2.js"></script>
<script src="jquery.mobile-1.2.0/jquery.mobile-1.2.0.js"></script>
</head>
<body id="body">
<div id="container" data-role="page">
New page!
</div>
</body>
</html>
Let me know about your results.
Try this solution by Piotr Walczyszyn. Highly recommended for anyone using Jquery mobile and Phonegap together.
