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.

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.
<head>
<meta charset="utf-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="viewport" content="width=device-width, initial-scale=1"/>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.11.4/themes/start/jquery-ui.css" />
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.5/jquery.mobile.structure-1.4.5.min.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<script type="text/javascript" src="cordova.js"></script>
</head>
<body onload="onLoad();">
<div data-role="controlgroup" data-corners="false">
Home
Settings
</div>
<!-- Ajax Requests -->
</body>
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.

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>
I have some troubles with JQuery and JQuery mobile.
When i click on the links in my page, i have this error :
Uncaught Error: cannot call methods on page prior to initialization; attempted to call method 'bindRemove'
I have tried to change the position of the link rel and scripts, but it breaks my design...
Someone have an idea ?
Here is my code :
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<!-- Include meta tag to ensure proper rendering and touch zooming -->
<meta name="viewport" content="width=device-width, initial-scale=1">

<div id="student-link"><img src="img/ic_student.png" /></div>
<p class="wemind-font">Student</p>

<div id="parent-link"><img src="img/ic_teacher.png" /></div>
<p class="wemind-font">Teacher</p>
</div>
Thank you in advance
Something in your js/ scripts is trying to act on a Mobile widget before it's initialized. Find whatever function is using bindRemove as a parameter and call it without any arguments first to initialize its widget before you call bindRemove.
I tried this :
<script>
$( document ).ready(function() {
$( "a" ).click(function( event ) {
window.location = $(this).attr("href");
});
});
</script>
i put this in the
but when i logout, i'm redirected to this page and the problem appear again...
I should be able to click a link without problem, it's very odd with a code that simple !
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

<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1" />

<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>');
I have an initial init page in my application that acts as an entry point and loads my login page.

When my login page loads there is a button which loads a dialog. This button initially doesn't work and only loads the dialog when the page is manually refreshed. Why does this happen and what can I do to enable the button/dialog immediately upon page load.

Not sure if you've fixed this but it seems to be something to do with the DOM cache & AJAX.
I'm not sure how you'd do it, but try setting the ajax: false when you do the window reload. Alternatively you could redirect via server side (I'd recommend this as it'll still work if the user has JS turned off.
Why I figured this out was because I had a page with a list on it, the list items sent me to a new page which has a jump link on it (#settings_dialog). Setting the data-ajax="false" on each list item somehow 'refreshed' the DOM and forced the second page to load 'fresh' and voila - my dialog works 100% now.
So, in short, turn off the AJAX feature or (better) redirect from serverside & be happy!
