why does the test message shows twice on:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
</head>
<body>
<script type="text/javascript">
alert("Test");
</script>
</body>
</html>
I copied the headers from from http://jquerymobile.com/demos/1.2.0/docs/about/getting-started.html and as I started doing some examples I noticed that my javascript methods where being called twice.
Here is the code in JsFiddle:

As Explosion Pills perfectly stated you have to play by jQM rules. At least:
Use appropriate jQM markup for a page or pages
<div data-role="page" id="page1">
<div data-role="header">
<h1>Page Title</h1>
</div><!-- /header -->
<div data-role="content">
<p>Page content goes here.</p>
</div><!-- /content -->
<div data-role="footer">
<h4>Page Footer</h4>
</div><!-- /footer -->
</div><!-- /page -->
Use pageinit event instead of jQuery ready handler.
So instead of
$(function() {
alert("Test");
});
use
$(document).on("pageinit", "#page1", function(){
alert("Test");
});
jsFiddle is here
You can use
$(function() {
alert("Test");
});
.. just fine, as long as you put it outside of the div with data-role="page".
No script tags allowed inside the page markup.

I need to be able to choose when the jquery dialog opens up but nothing i seem to do works.
so far ive tried this
<html>
<head>
<meta charset="UTF-8">
<title>Document</title>
<!-- Include meta tag to ensure proper rendering and touch zooming -->
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- Include jQuery Mobile stylesheets -->
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css">
<!-- Include the jQuery library -->
<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<!-- Include the jQuery Mobile library -->
<script src="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
</head>
<body>
<div data-role="main" class="ui-content">
Open Dialog Popup
Test
<div data-role="popup" id="myPopupDialog">
<div data-role="header">
<h1>But wait theres more!</h1>
</div>
<div data-role="main" class="ui-content">
<h2 style="text-align: center;">Would you like an exclusive offer?</h2>
Sounds Good!
No Thanks, Take me back..
</div>
<div data-role="footer">
<h1>Footer Text</h1>
</div>
</div>
</div>
<script>
$(document).ready(function(){
console.log(document.body.scrollTop);
if(document.body.scrollTop === 0)
{
$.mobile.changePage('#myPopupDialog', 'pop', true, true);
}
});
</script>
</body>
</html>
which works but when i change the if statement in the javascript it breaks also if i remove the anchor tag at the top it just doesnt show... jQuery mobile has me confused.
So anyway my question is how do manually make a dialog box show on the page, i would prefer it to show on the same page and not another page.
use this:
$("#myPopupDialog").addClass("ui-page-active ui-page ui-page-theme-a")
I am developing a web app based on jQuery and jQuery mobile. I want to show different pages, but since the corresponding html-markup might become quite large I would like to split up the html into different files, i.e.:
<html>
<head>
<meta charset="utf-8" />
<link rel="stylesheet" type="text/css" href="css/jquery.mobile-1.4.3.min.css" />
<title>Hello World</title>
</head>
<body>
<div data-role="page" id="page1">
<!-- import markup for page1 here -->
</div>
<div data-role="page" id="page2">
<!-- import markup for page2 here -->
</div>
<script src="js/libs/jquery-2.1.1.min.js"></script>
<script src="js/libs/jquery.mobile-1.4.3.min.js"></script>
</body>
</html>
What can I do to import my markup where it says <!-- import markup for page<x> -->? Is there any way to achieve that?
I tried using <script>$("#page1").load("page1.html");</script> but this messes the entire page up! Since the web app should be packed as a native app for smartphones later php is not an option.
Thanks to Omar's comments above and his answer to this question I was able to come up with a working solution.
1.) Add external pages to the DOM by using $.mobile.pageContainer.pagecontainer("load", "<externalResName>.html");
2.) Navigate to the newly loaded page by adding a listener to the document (i.e. $(document).on( "pagecontainerload", function( event, ui ) { //... } );)
3.) Make sure that the external ressource stays in the DOM by adding data-dom-cache="true" to the page's div-tag.

I'm using JQuery mobile on Apache Cordova for android. Javascript between the body tags works, but javascript files that I link to in the header don't execute, even on the first page loaded.
I read a lot about problems with JQuery loading javascript due to the way ajax parses linked pages - however in this case embedded javascript isn't even working on the main page, and I can't find any answers to this problem
Here is index.js:
$(document).ready(function() {
// Handler for .ready() called.
document.addEventListener("deviceready", onDeviceReady, true);
});
function onDeviceReady() {
alert('index js loaded successfully');
}
And here is index.html. The alert('index') works but alert('index js loaded successfully') does not appear
<html>
<head>
<meta charset="utf-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1" />
<link rel="stylesheet" href="css/jquery.mobile-1.4.0.css" />

<body>
<script type="text/javascript">alert('index');</script>
<script src="js/jquery-1.11.0.js"></script>
<script src="js/cordova.js"></script>
<script src="js/index.js"></script>
<script src="js/jquery.mobile-1.4.0.js"></script>
<!-- Start of first page: #one -->
<div data-role="page" id="one">
<div data-role="header">
<h1>Main Menu</h1>
</div><!-- /header -->
<div data-role="content" >
<p> content here </p>
</div><!-- /content -->
<div data-role="footer">
<h4>Page Footer</h4>
</div><!-- /footer -->
</div>
</body>
</html>
You said embedded js isn't working on your main page yet your alert("index") works. That's slightly contradicting and confusing. Unless you're definition of embedded is different.
Regardless, I'm thinking that the javascript files aren't loading in the correct order.
For the project I use, I have something along the lines of:
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="js/jquery-1.9.1.min.js"></script> //This order matters #1
<script type="text/javascript" src="js/MY_CUSTOM_JS_RAWR.js"></script> //This order matters #2
<script type="text/javascript" src="js/jquery.mobile-1.3.2.min.js"></script> //This order matters #3
Then, within the MY_CUSTOM_JS_RAWR file, I'm doing the method described in this answer.
I have a script which should append some element to the Content div, but it didn't work.
As you see the content of the "messageBox" is arrives from a php file which select the mysql table and the data from it.
Here is the JS file's content:
function getWallMsg(){
$.getJSON('SELECT_uzenofal.php?callback=?',function(data) {
data.forEach(function(e){
$('#posts').append($('<div class="messageBox">'+'<img src="img/profilok/'+e.kep+'"/>'+'<p class="name">'+e.nev+'</p>'+'<p>'+e.uzenet+'</p>'+'<p class="time">'+e.ido+'</p>'+'</div>'));
});
});
}
$(document).ready(function(){
drawNavbar();
getWallMsg();
});
And the html:
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" >
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.css" />
<link rel="stylesheet" type="text/css" href="css/main.css">
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script type="text/javascript" src="js/main.js"></script>
<script src="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.js"></script>
</head>
<body>
<!-- Home -->
<div data-role="page" id="fal">
<!-- header -->
<div data-role="header">
<h3>
Üzenőfal
</h3>
</div>
<!-- content -->
<div data-role="content" id="posts">
</div>
<!-- footer -->
<div class="nav" data-role="footer" data-position="fixed" data-theme="a"></div>
</div>
</body>
What should I do?
This should be changed:
$(document).ready(function(){
drawNavbar();
getWallMsg();
});
to this:
$(document).on('pagebeforeshow', '#fal', function(){
drawNavbar();
getWallMsg();
});
Basically document ready should not be used with jQuery Mobile, to find out more about this take a look at this ARTICLE, to be transparent it is my personal blog. Or find it HERE.
Basically you are trying to append it on document ready when page content is not loaded into the DOM. Instead proper jQuery Mobile page event, like pagebeforeshow, should be used.
EDIT :
You were adding an incorrect id to the pagebeforeshow even. It should work now.
could not comment so posting as answer.
$('#posts').append($('<div class="messageBox">'+'<img src="img/profilok/'+e.kep+'"/>'+'<p class="name">'+e.nev+'</p>'+'<p>'+e.uzenet+'</p>'+'<p class="time">'+e.ido+'</p>'+'</div>'));
have you tried changing above to
$('#posts').append('<div class="messageBox">'+'<img src="img/profilok/'+e.kep+'"/>'+'<p class="name">'+e.nev+'</p>'+'<p>'+e.uzenet+'</p>'+'<p class="time">'+e.ido+'</p>'+'</div>');
Hey still new to JS/CSS/HTML well basicly webdevelopment.
I have a page, for which I'm loading most of the stuff dynamicly. If i goto it by window.location="mapmode.jsp" Then it doesn't load properly but if I do an <a href> tag it loads fine.
Also if I do pagerefresh on the fine page, it loads in badly again.
Could be a jquerymobile thing maybe, but I'm just not sure..
The way I initialize the dynamic stuff might also be relevant so here it is:
$(document).on("pageinit", "#mapmode", function(event) {
initPageHeader();
});
Any help would be appreciated.
edit: mapmode.jsp:

jQuery Mobile sidesteps your browsers linking and history. It automatically wires this up for links (<a href>). But for JavaScript you need to use their changePage method.
For example:
$.mobile.changePage('pagename.jsp');
See the linked documentation for more information and options when using changePage.
