My javascript does not seem to load at all when i am using android's webview but loads fine on a desktop browser
Here is my html and script under one html file:
<script>
function initialiseFields(){
var name = "John Smith";
var staffId = "9877878";
alert( 'initialiseFields' );
$("#list").append('<li><h3>Additional Information:</h3><div data-role="fieldcontain"><input type="text" name="claimTitle" id=/"textFieldJourneyFrom" value="" /></div></li>');
$('#list').listview('refresh');
}
</script>
<body onLoad="initialiseFields();">
<div data-role="content">
<ul class="ui-li" data-role="listview" id="list" data-inset="true" data-scroll="true">
</ul>
</body>
Basically trying to execute the initialiseFields that displays an alert and add some field into the listView.
The alert and the listView never gets invoked/updated.
Edit: Also, whatever list item I add via javascript, it doesnt apply the default jquery mobile css style either.
Any reason why?
Another Edit:
Solution is provided by the person i have accepted the answer, however a word of warning. if you are using a datepicker and its assets. the soltuons provided doesnt work i.e it doesnt load your JS for some strange reason:
<link href="jQueryAssets/jquery.ui.core.min.css" rel="stylesheet" type="text/css">
<link href="jQueryAssets/jquery.ui.theme.min.css" rel="stylesheet" type="text/css">
<link href="jQueryAssets/jquery.ui.datepicker.min.css" rel="stylesheet" type="text/css">
<link href="jQueryAssets/jquery.ui.button.min.css" rel="stylesheet" type="text/css">.
Also, i tried the above snippet of code by simply setting the theme and it managed to apply the theme on the text and header and background but on the actual field it does not apply it to the input field
$("#list").append('<li data-theme="c"><h3>Additional Information:</h3><div data-role="fieldcontain" data-theme="c"><input type="text" name="information" id=/"textFieldInformation value="" data-theme="c"/></div></li>');
edit 2:
Code was tested and working ok except for the theme of the input fields, however, my JS does not work at all on an android device.
When working with jQuery Mobile don't use inline javascript function initialization. Mainly because this problem could happen.
jQuery Mobile page is not a normal web page. Unlike classic web development jQuery Mobile will restyle whole page when it is initially loaded into the DOM. This will work fast on desktop browsers but it will take time to run on mobile browsers / web views (no matter is it Android or iOS). Because this restyling takes time this inline function will execute before content is full loaded/enhanced inside the DOM. This is also a reason why document ready should not be used with jQuery Mobile, because it will usually trigger before it can be useful.
To counter this problem you should use jQuery Mobile page events. They are specially created to cover page loading states from initial DOM loading up to final page show.
But to make it work you will need to change your HTML a bit. Your div with data-role="content" must be wrapped into a div with an attribute data-role="page", something like this:
<body>
<div data-role="page" id="index">
<div data-role="content">
<ul class="ui-li" data-role="listview" id="list" data-inset="true" data-scroll="true">
</ul>
</div>
</div>
</body>
For page event to work you web app MUST have data-role="page" divs.Also your data-role="page" div must have an id, we will use this id to initialize your function.
Now to make it work just initialize your function like this:
$(document).on('pagebeforeshow', '#index', function(){
initialiseFields();
});
If you want to find out more about page events read this ARTICLE, to be transparent it is my personal blog. One last thing, you need to know how jQuery Mobile handles multiple pages and javascript initialization so find more about it HERE.
You can test it here: http://jsfiddle.net/qhvne/2/embedded/result/

I know it has been explained in many places here but I can't get it to work.
It concerns: how to use JavaScript which is in - under wwwroot created - folder in a *.js file.
What I am using:
Blazor Server App empty (VS2022, C#).
I only need/use Server App in VS2022 C# and empty - without any predefined navbars and other elements. So there are no any *.cshtml files except one which is automatically created while creating a "Blazor Server App Empty" in VS 2022 and that is "_Host.cshtml"
And I don't want to use any other template in VS 2022, only this one mentioned.
So, after creating a "page" using this in VS integrated template, I added following in MainLayout.razor (I am using *razor and only razor - no any cshtml):
// this was originally created as in the template in VS2022
#inherits LayoutComponentBase
//this one also:
<main> #Body </main>
// That is what I added here in MainLayout.razor, it's from this site: [http://jsfiddle.net/Ag47D/3/](https://www.stackoverflow.com/)
<div class="navbar">
<div class="navbar-fixed-top">
<div class="container" style="width: auto;">
<div class="nav-collapse" id="nav-collapse">
<ul class="nav" id="nav">
<li id="home">Home</li>
<li id="skill">Skill</li>
<li id="research">Research</li>
<li id="link">Link</li>
</ul>
</div>
</div>
</div>
</div>
And then I added the css part to the existing "site.css" in that simply VS 2022 project:
`.navbar #nav > .active > a {
color: red;
}`
And finally - and that is the big issue for me to understand WHRE/HOW to handle that . a simply JavaScript part (you can find that on the same site mentioned):
` $(function() {
$('#nav li a').click(function() {
$('#nav li').removeClass();
$($(this).attr('href')).addClass('active');
});
});`
I added that to a created folder in wwwroot, the flder is called: "js" and the file inside that folder is called: "setactivetab.js". In that file is the mentioned part of javascript.
In "_Host.cshtml" I added then that, here the part of that _Host.cshtml where you can see what I added:
`....
....
Reload
<a class="dismiss">🗙</a>
</div>
<script src="~js/setactivetab.js"></script>
<script src="_framework/blazor.server.js"></script>
</body>
</html>`
So I tried with:
<script src="~js/setactivetab.js"></script>
and:
<script src="js/setactivetab.js"></script>
and:
<script src="~/js/setactivetab.js"></script>
But nothing worked. I mean: TABS are shown on the page - no question about that - but if I click on one of that TABs - nothing happens, the color isn't changed.
Somehow I am not able to understand how to use a self created/from google downloaded, JavaScript for simply changing of the color or to set a selected TAB as active/current or however we can use that.
I tried so many examples described on the web. I can't get that working - maybe I am missing/not understood some fundamental knowledge of using a JavaScript. I simply don't know the way how one can use that.
Can you please post me here a working example of a navigation TABS, ideally self created and simply? Important is: WHERE to put a javascript and how to access that properly so the clicking on a TAB wil lchange his color and stay so until I click on another TAB in a simply - if possible: horizontal, not vertical, navigation bar.
I have enough from searching/reading of many web sites descriptions as there works all and if I copy&paste some simply example, it doesn't work.
I am playing around with djax when I click an anchor tag the url changes and when I view the page source it also changes but the page itself did not change its contents even if I view the page source it has change up any ideas why?
Here's a snippet of the markup
<body>
<div id="resultContent" class='updatable'></div>
<ul>
<li><a id="thankyou" href="views/thankyou.jsp?menuId=2"
targets="resultContent">Thank You Message</a></li>
</ul>
</body>
When I click that the url changes but the result is not showing but when I view the page source it displays the proper markup(or should I say the markup of thankyou.jsp)
here is the code that Is js code
jQuery(document).ready(function($) {
$('body').djax('.updatable');
});
I've had the exact same problem as you and discovered your question while I was looking for an answer. It may be too late for you but according to your markup I believe you ran into the same problem as me which is actually on the issue-list of the plugins Github site (at least right now).
You need to place your updateable div inside a wrapping div. For some reason exchanging content seems not to work for direct children of body. See https://github.com/beezee/djax/issues/22
So your HTML should look like this
<body>
<div id="djaxWrap>
<div id="resultContent" class='updatable'></div>
<ul>
<li><a id="thankyou" href="views/thankyou.jsp?menuId=2"
targets="resultContent">Thank You Message</a></li>
</ul>
</div>
</body>
While jQuery remains the same
jQuery(document).ready(function($) {
$('body').djax('.updatable');
});
We have a single page application with two views (essentially, a list of items and a details page for the selected item). Both views are in separate html files, and we’re using sammy.js to transition/navigate between the pages. Everything was working great until we tried to add jQuery Mobile to the mix. Now, when we navigate to the second page (the details page), jQuery Mobile is not styling the page.
Our working app is not set up as described by jQuery Mobile’s multi-page template (i.e., having all page divs in the same html file and use their navigation system to load linked pages into the DOM via AJAX). But, is it possible to have separate pages, use something other than jQuery Mobile’s navigation, and still have jQuery Mobile style the second page? Or, is there a way to force jQuery Mobile to style the second page?
Here’s some code snippets that’ll hopefully help show what we’re doing. (Note: We’re also using ASP.NET razor views.)
index.cshtml
<body>
#RenderPage("Views/items.cshtml")
#RenderPage("Views/item.cshtml")
#Scripts.Render("~/bundles/jquery")
<script>
$(document).bind("mobileinit", function () {
$.mobile.ajaxEnabled = false;
$.mobile.hashListeningEnabled = false;
$.mobile.pushStateEnabled = false;
$.mobile.loader.prototype.options.text = "loading. please wait...";
$.mobile.loader.prototype.options.textVisible = true;
});
</script>
#Scripts.Render("~/bundles/jquerymobile", ...)
</body>
items.cshtml (this page gets loaded and rendered correctly)
<section id="items-view" class="view" data-role="page">
<section data-role="header">
....
</section>
<section data-role="content">
(navbars, ULs, LIs, etc. are here, with each LI a link to go to the details page)
</section>
<section data-role="footer">
....
</section>
</section>
item.cshtml (this page gets loaded but NOT rendered correctly, there is no jQuery Mobile styling)
<section id="item-view" class="view" data-role="page">
<section data-role="header">
....
</section>
<section data-role="content">
(ULs, LIs, listboxes, textboxes, etc. are here)
</section>
<section data-role="footer">
....
</section>
</section>
router.js (used to route between pages)
....
navigateTo = function (url) {
sammy.setLocation(url); // url = #/items or #/item/1234
},
....
In the js file for the item page, we’ve tried:
var $page = $("#item-view");
//$page.trigger("create");
//$page.listview("refresh");
//$page.page(); (this one kind of work but doesn’t style every object)
//$page.page("refresh", true);
but haven’t got any thing to work correctly and completely.
So, again, given our situation, is there a way to have a jQuery Mobile multi-page app with actual separate physical files and have all pages get style correctly? Or is there a programmatic way to force jQuery Mobile to style all pages correctly?
Thanks.
jquery mobile does NOT load everything from your second page.
when you require a new page with JQM (or it's ajax method), it loads parts of your page's DOMs and get all things under
<div data-role="page" id="yourPageID"></div>
so your could simply try put your stylesheet under "data-role", like this:
<div data-role="page" id="yourPageID">
<link rel="stylesheet" href="yourStyleSheetLink.css" />
</div>
then, when JQM requires a new page, your stylesheets will be loaded.
as a non-English speaker, i hope you can understand my words :)
I am creating a jquery mobile web app which contains 3 pages, my header/nav for these pages doesnt change but in all the examples Ive seen the header and footer is added to each page. Is it possible just to add 1 nav and 1 footer then just switch the pages main content in and out like this structure:
<div id="header" data-role="header"></div>
<div id="page1" data-role="page">content</div>
<div id="page2" data-role="page">content</div>
<div id="page3" data-role="page">content</div>
<div id="footer" data-role="footer"></div>
Basically is there a way of just showing/hiding the main content and doing nothing with the header and footer?
Any advice on this would be great
Kyle
No, unfortunately JQM doesn't support this (yet), you'll need to add your role=header and role=footer on EVERY role=page you got (all 3 of them).
See documentation
I would stick to $.mobile.changePage() since that takes care of hashing and a lot of other events and not just use JQuery to .load() new content...
Hope this helps
Have a look at the load() method in jQuery -> http://api.jquery.com/load/
Here is an exmaple :
$('#navigation').click(function() {
$('#page1').load('page1.html');
});
This means that when something with an id of navigation is clicked it will call the load() function and replace the div with id of page1 with the contents of the loaded file.
you can use .load() in jQuery
for example in every page you will have this:
<div data-role="footer" class="ui-footer"></div>
now build this function:
function goTo(pageURL, transitionType) {
$.mobile.changePage(pageURL, transitionType);
$('.ui-footer').load('assets/includes/footer.html');
}
now when you move between pages, try onclick (or from code if you like) call:
goTo('home.html','slideup');
that would do the trick (this is what I use)
you can do the same for the headers as well.
keep in mind if the header or footer content changes for each version of the app (such as localization) you have to call this first, then fill in the localization text or anything else.
I hope this helps for your purpose
It looks like jQuery mobile sets document.title to the text content of data-role="header", example:
<div data-position="fixed" data-role="header">
<h1>This text</h1>
</div>
I have a hack workaround to prevent this as such:
$('div[data-role="page"]').bind('pageshow',function(){document.title = "My title"});
Is there a better/more semantic way to do this?
Another solution would be to copy the original document title to the data-title attribute of each page:
$(":jqmData(role='page')").attr("data-title", document.title);
The advantage of this approach over changing the title on pageshow is that it will prevent document title flicker during page transitions.
If you wrap your value around div it will not update the title. Like this:
<div data-position="fixed" data-role="header">
<div><h1>This text</h1></div>
</div>
I would just patch jQuery mobile to remove the unwanted behaviour. It appears to be in jquery.mobile.navigation.js. You could rebuild jQuery Mobile to get the minified version again.
If you were feeling ambitious, you could even submit a bug to jQuery Mobile asking that this be an option (and possibly even write a patch yourself, if you're comfortable doing so).
The jqmData option here didn't work for me. The H1 wrapping option messed up the looks which I would need to correct through CSS. What did work for me and is actually documented by jQuery Mobile is:
http://demos.jquerymobile.com/1.1.2/docs/pages/page-titles.html
Which comes down to adding the data-title attribute to the div with data-role="page":
<div data-role="page" data-theme="a" data-title="MyPage - #ViewBag.Title">
In this particular example I'm setting the page title to "MyPage - " followed by the page title as set through MVC in the ViewBag.
$(":jqmData(role='page')").attr("data-title", document.title);
This works as proposed by #stanislaw-osinski - however, I had to use it like this to get it work in jQuery Mobile v1.4.5:
<script>
$(document).bind("pageinit", function(){
// Patch to prevent overwriting <title></title>
$(":jqmData(role='page')").attr("data-title", document.title);
});
</script>
