.load() info is not recognizing the CSS styles [duplicate] - javascript

This question already has answers here:
jQuery Mobile does not apply styles after dynamically adding content
(4 answers)
Closed 8 years ago.
I am making an HTML5 app, and I am loading data from a database into the HTML by using the .load() function of jQuery. The function work great, but the problem is that the HTML code loaded is it not modified by the style sheet (jQuery Mobile). The reason that I am doing this is because I would be using PhoneGap Build to get an android app.
Here is my code break into pieces:
HEAD:
<head>
<title>Parking Lot App</title>
<meta name="viewport" content="width=device-width, initial-scale=1" />
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.1/jquery.mobile.structure-1.3.1.min.css" />
<link rel="stylesheet" href="themes/florida_tech.min.css" />
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$( "#maps" ).get( "map_list.php");
window.setTimeout(function(){ document.location.reload(true); }, 10000);
});
</script>
</head>
BODY:
<body>
<!-- HOME PAGE -->
<div data-role="page" id="home_page" class="name" data-theme="a">
<!-- HEADER HOME PAGE -->
<div data-role='header' id='header'>
<h2>
Parking Lot App
</h2>
<a href='index.html' data-iconpos='notext' data-icon='home'></a>
</div>
<!-- CONTENT HOME PAGE -->
<div data-role="content" data-theme="a" id="maps">
</div>
<!-- FOOTER HOME PAGE -->
<div data-role="footer" data-position="fixed">
<h3> Senior Design Project </h3>
</div>
</div> <!-- END OF HOME PAGE -->
</body>
And finally the file (after loading) that I am having trouble with, MAP_LIST.PHP:
<ul data-role="listview" data-inset="true" data-divider-theme="a" data-count-theme="b">
<li data-role="list-divider"> Parking Lots </li>
<li>
<a href="#mapdata1"
data-inline="true"
> Parking Lot 1
<span class="ui-li-count">0</span></a></li><li><a href='#info'> Help </a></li>
</ul>
I was wondering if there is another/better way to paste the data from the database into my HTML code so that the styling would modify the code.

When using .load() or .get() isn't the same as using insertion functions e.g. append() / prepend(). The former functions use Ajax to pull data, so you need to call enhancement after Ajax call is done.
Using .get()
$.get("URL", function (data) {
var list = $(data).find("#listID");
$("#target_div").append(list);
$("#listID").listview();
}, "html");
Inside URL, give listview an id.

jQuery mobile Datebox CSS not loading properly

I have a simple two page website developed using jQuery mobile framework. I had the need to use Datebox plugin for selection of times. Both pages of my website are in the same .php file separated by divs with data-role="page" appropriately.
My only problem is that if the datebox exists in the first page of the webpage, it loads properly, but in any other page, its icons are messed up.

The following images show the issue. On page load, the first div with page-role="page" and id="index" is loaded and the datebox icon works as intended:
But if I navigate to the second page using the footer navbar ON/OFF tab, I get this weird icon placement:
Please help me figure out what is going wrong here.
Hmm, I'm not sure why this is but using local files instead of the CDN links in the head enabled me to use the datebox plugin across pages. The files were generated using the download builder found here:
http://dev.jtsage.com/DateBox/builder/
user3889963 hit the nail on the head.
Download the source files for JQM for Datebox and then call them directly within your head.
<script src="../jtsage-datebox.min.js" type="text/javascript"></script>
<link href="../jtsage-datebox.min.css" rel="stylesheet">
This previous question shows there is a problem with using the plugin via the CDN Jquery Mobile DateBox plugin only working when linked directly to page
Here is it working with the files installed directly.
Unique Naming is the problem.
Within both pages you are calling the datebox item by the same name, so only the first one gets styled correctly.
Just rename the second page as datebox2 this should fix the problem. As the label for searches for the first unique ID of "datebox" and styles that one.
<div data-role="main" class="ui-content">
<div class="ui-field-contain">
<label for="datebox2">Time (seconds)</label>
<input type="text" data-role="datebox" data-options='{"mode":"calbox"}'>

<head> JS scripts are not executing

I'm using JQuery Mobile, and now I would like to navigate through pages with the minimum of loading amount of scripts everytime a page is being loaded, I mean that I would like to import only ONCE all the general scripts of all the pages (JQuery.js, jquery_mobile.js, main.js etc...) and
So I have an index.html with the following code :
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=0">

<link rel="stylesheet" href="jqueryMobile/jquery.mobile.icons-1.4.4.css" />
<link rel="stylesheet" href="css/jquery.mmenu.css" />
<link rel="stylesheet" href="css/main.css" />
<script>window.$ = window.jQuery = WLJQ;</script>
<script type="text/javascript" src="js/jquery-2.1.1.js"></script>
<script type="text/javascript" src="jqueryMobile/jquery.mobile-1.4.4.js"></script>
<script type="text/javascript" src="js/jquery.mmenu.min.js"></script>
<script type="text/javascript" src="js/initOptions.js"></script>
<script type="text/javascript" src="sharedResources/customersObject.js"></script>
<script type="text/javascript" src="js/main.js"></script>
<script type="text/javascript" src="js/messages.js"></script>
</head>
<body style="display: none;">
<div data-role="page" id="page">
<link rel="stylesheet" href="css/pages/splash-view.css" />
<div data-role="header" id="header" data-position="fixed"></div>
<div data-role="content" id="pageContent">
<div id="splash-wrapper">
<div class="splash-content">
Login
</div>
</div>
</div>
<div data-role="footer" id="footer" data-position="fixed"></div>
<nav id="menu">
<ul data-role="listview" data-inset="true">
<!-- list of items in the slide sidebar menu (called drawer menu in Andorid -->
</ul>
</nav>
<script src="js/pages/splash-view.js"></script>
</div>
</body>
so when clicking on the link I go to an external HTML file located in : pages/faqs-view.html with the following code :
<div data-role="page" id="page" data-url="pages/faqs-view.html">
<link rel="stylesheet" href="css/pages/faqs-view.css">
<div data-role="header" id="header" data-position="fixed"></div>
<div data-role="content" id="pageContent">
<div id="faqs-wrapper">
<div class="faqs-content">
<div data-role="collapsible-set" data-corners="false" data-collapsed-icon="arrow-r" data-expanded-icon="arrow-d" id="faq-set">
</div>
</div>
</div>
</div>
<div data-role="footer" id="footer" data-position="fixed"></div>
<nav id="menu">
<p class="employee-name">Welcome, Ali</p>
<ul data-role="listview" data-inset="true">
<!-- list of items in the slide sidebar menu (called drawer menu in Andorid -->
</ul>
</nav>
<script src="js/pages/faqs-view.js"></script>
The problem is that when loading the faqs-view.html page, I can see that none of the scripts included in the <head> are being executed, I have tried to put them after the <body> tag, but it's the same, BUT the CSS files are being interpreted.
How can I achieve that ? Thank you.
Worklight-based applications are Single Page Applications. This means you should never navigate away from the index.html. Doing so will cause the app to lose its context to the Worklight framework, thus it will begin to fail.
If you'd like to add multi-page navigation to the application, you can do so using the API provided by 3rd-party frameworks. Here you are using jQuery Mobile.
You've changed the loading order of scripts. You shouldn't.
Use the Worklight Studio wizard in order to create an app template with jQuery Mobile (new project > new hybrid application (click on "configure javascript libraries" > select the library you would like to add))
Keep initOptions.js, main.js and messages.js where they are by default, at the bottom
The index.html you get is your template with jQuery Mobile
If you want to replace the bundled jQuery, you need to comment out (slide #6) the following script tag: <script>window.$ = window.jQuery = WLJQ;</script>. Worklight is bundled with jQuery 1.9.x.
For a bare-bones example of multi-page navigation in a Worklight-based application, using jQuery Mobile, take a look at this project.
As you navigate between pages, you only replace the contents of the data-role="page". The scripts have already been loaded. You can load additional scripts per where required when loading a specific page.
They are executed in the order you put them on the page.
window.$ = window.jQuery = WLJQ;
Cannot be executed before jQuery is included.
Edit:
When you load a new page without the header it's clear that it won't be excecuted because it is not there.
When you replace html in your page you should look at the "on" function for events.

Javascript doesnt run when navigating through listview , jquery mobile

I am developing a jquery mobile website and i have some problems running javascript code.
I have a home page , index.html , which is basically a listview to navigate to various html pages. I use the single-page structure for my pages , that means every 1 html file contains 1 page. Now from the home page , i navigate to another page where i am using a persistent NavBar with a horizontal button with 2 options. One is photos and the other is multimedia.
For the photos i am using the Javascript FB API , to download the photos from a FB Page and then with the PhotoSwipe Plugin i present them to the user.
The problem..
If i run the photos.html page , it will work well and load the albums. There are 2 things that my javascript does. 1) Use FB API to get albums, photos , cover photos etc.. 2) Dynamically create a listview with this albums and their photos. In this case both work great!
However when i am in my index.html and i navigate through the listview to the photos.html (photos is the default chosen button from the persisent NavBar) the Javascript code doesnt work. Like is not called at all..
The index.html looks like:
<!DOCTYPE html>

As you see i call my javascript in the end. Any ideas why its never called? If i refresh the page , that means run the photos.html , it will load normally.
Actually i also look at the "elements" table from the debugger. When im in the index.html page the html elements seem all correct. When i do the transition though to the photos.html page , by looking at the elements table i see that they dont change! The title does change but the rest stays the same which is incredible?! How on earth can that happen? It looks like is the same page , with the same css and javascript sources , but should be different! As you see i use photoSwipe javascript , css etc! Only if i reload the page the elements are correct. Please any ideas? I have no idea what is happening here.
Also for some reason i get a 304 Status , Not Modified through the transition , from one page to another.
The reason for this is because when you navigate to a page in jQuery Mobile it by defaults will try and pull the JQM page (data-role="page" (if there is no data-role='page' then it will pull the body)) via ajax and attaches it to the current page's DOM, the thing is it will only pull the JQM page (or body if there isn't any) and ignore everything (aside from the title) outside of it meaning your JavaScript is not going to get called.
When you refresh the page then a normal HTTP call is made and the entire page is loaded so your code is executed.
In order to have your JavaScript called you need to either have the relevant script's on your first page or you can have it withing your JQM page wrapper and it will then be pulled along with it.
<div data-role="page" id="photos" data-theme="a"
data-add-back-btn="true" data-back-btn-text="Back">
....
<script type='text/javascript' src='javascript/createAlbums3.js'></script>

JQuery Mobile do something on page load when clicked on navbar item

I have a page with some nabars, and when the "My Activity" navbar is clicked I want it to do something on load, and currently for testing purposes, I am just trying to alert a message to screen on load, but since it is a js file being called I am not sure, what Jquery mobile load function to use?
here is my html for the page:
<html>
<head>
<title>My Activity</title>
<meta name="viewport" charset="UTF-8" content="width=device-width, initial-scale=1"/>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.css"/>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.js"></script>
<script type="text/javascript" src="http://www.modernizr.com/downloads/modernizr-latest.js"></script>
<style>
</style>
</head>
<body>
<div data-role="page">
<div data-role="header" data-id="pagetabs" data-theme="a" data-position="fixed">
<div data-role="navbar">
<ul>
<li>Facebook</li>
<li>YouTube</li>
<li>My Activity</li>
</ul>
</div>
</div>
</div>
<div data-role="footer" data-theme="a" data-position="fixed"><h5>Social Stream</h5></div>
</div>
<script src="my_activity.js"></script>
</body>
</html>
and in my my_activity.js file I have tried different, page load functions. I tried the following, that only gets fired when you manually refresh the browser, doesn't get fired when you click on the navbar tab
$(document).on('pageinit', '[data-role="page"]', function(){
alert("hello");
});
Put this line:
<script src="my_activity.js"></script>
Inside a page div, like this:
<div data-role="page">
<div data-role="header" data-id="pagetabs" data-theme="a" data-position="fixed">
<div data-role="navbar">
<ul>
<li>Facebook</li>
<li>YouTube</li>
<li>My Activity</li>
</ul>
</div>
</div>
<div data-role="footer" data-theme="a" data-position="fixed"><h5>Social Stream</h5></div>
<script src="my_activity.js"></script>
</div>
You are suffering from a classic jQuery Mobile problem. This topic is not discussed as a part of an official documentation so I will try to explain it to you.
When jQuery Mobile loads additional HTML pages it only loads page div (data-role="page"=, everything else is stripped. This is because HEAD already exist inside a DOM and another HEAD is not needs, same goes for a rest of the page.
If you want to find more about it take a look at my blog ARTICLE that discuss this topic. There you will find a better description plus few solutions with examples. Read it carefully.

You didn't post your javascript code but I think I know what is your problem.
All jQuery plugins that work with page height and width (in your case pie chart) MUST be initialized through pageshow event. This is because jQuery Mobile pages has correct height only at that point. So if page height is 0 plugin will initialize but with height set to 0.
So if you are doing it during the document ready or any other page event, switch your pie chart plugin initialization to pageshow evenet.
If you don't know what pageshow event is take a look at my other detailed answer: jQuery Mobile: document ready vs page events
EDIT :
I have fixed your problem.
To understand this situation you need to understand how jQuery Mobile works. It uses ajax to load other pages.
First page is loaded normally. Its HEAD and BODY is loaded into the DOM, and they are there to await other content. When second page is loaded, only its BODY content is loaded into the DOM.
Read more about it in my other answer other answer: Why I have to put all the script to index.html in jquery mobile
Add the below code inside pie chart page and remove onload="moteur();" function.
<script>
$(document).on('pageshow', '[data-role=page]', function () {
moteur();
});
</script>
Any scripts and styles referenced the head of a page won't have any effect when a page is loaded via Ajax, but they will execute if the page is requested normally via HTTP. When scripting jQuery Mobile sites, both scenarios need to be considered. The reason that the head of a page is ignored when requested via Ajax is that the potential of re-executing the same JavaScript is very high (it's common to reference the same scripts in every page of a site). Due to the complexity of attempting to work around that issue, we leave the task of executing page-specific scripts to the developer, and assume head scripts are only expected to execute once per browsing session.
The simplest approach when building a jQuery Mobile site is to reference the same set of stylesheets and scripts in the head of every page. If you need to load in specific scripts or styles for a particular page, we recommend binding logic to the pageinit event (details below) to run necessary code when a specific page is created (which can be determined by its id attribute, or a number of other ways). Following this approach will ensure that the code executes if the page is loaded directly or is pulled in and shown via Ajax.
Another approach for page-specific scripting would be to include scripts at the end of the body element when no data-role=page element is defined, or inside the first data-role=page element. If you include your custom scripting this way, be aware that these scripts will execute when that page is loaded via Ajax or regular HTTP, so if these scripts are the same on every page, you'll likely run into problems. If you're including scripts this way, we'd recommend enclosing your page content in a data-role="page" element, and placing scripts that are referenced on every page outside of that element. Scripts that are unique to that page can be placed in that element, to ensure that they execute when the page is fetched via Ajax.
