I have a multi page jquery mobile document.
Structure something like.
Page A
Page B
Page C
I know I can execute function on every pageshow by using pageshow but when u link back to page A say by #PageA in browser it leaves main URL only. So I want to execute a function when user is on mydomain.com
I can propose general solution. For each page you can have div
<div class="page_{variable}"></div>
and check by jQuery whether you have
$(".page_A"), $(".page_B")
and so on. I hope it helps.

situation:
form1.html has a button
clicking that button calls $.mobile.changePage('../site3/form2.html');
no problem here. all is as expected and the page is loaded. let's call that form2.html
form2.html has 2 sections:
(1) #SiteForm and
(2) #SiteSearched
clicking a button on #SiteForm should call $.mobile.changePage('../site3/form2.html#SiteSearched');
now here's the weird part.
if I load the page form2.html directly and press the button, it works and I see #SiteSearched JQM page.
but, if I start from form1.html, click the button to get to form2.html#SiteForm, then click the button, everything in the attached function executes, except the line calling $.mobile.changePage('../site3/form2.html#SiteSearched');
I know that part is loaded by AJAX by wouldn't the changePage command work?
(note: Form1 may have data filled into the form that I don't want to lose. Form2.html was meant to do a search and throw back the result to Form1 somehow, which is why I am doing things this way.)
You should read official jQuery Mobile documentation before posting here, everything is explained there, but let me give you a short explanation.
jQuery Mobile has two template solutions, one is multi page and second one is multi html. You already know that because you are mixing them. But, what you don't know is (from the perspective of AJAX page handling):
Only first HTML page is fully loaded into the DOM, everything is loaded, including the HEAD content. So if initial HTML page has several data-role="page" <div> containers, every one will load into the DOM.
But, every subsequent page is loaded only partially. Basically if you second, third ... page has more then one data-role="page" div containers only first one will load into the <DOM>. jQuery Mobile will discard everything else.
So in your case, if form2.html has:
(1) #SiteForm and
(2) #SiteSearched
jQuery Mobile will load only #SiteForm, #SiteSearched will get discarded.
Basically this line will not work:
$.mobile.changePage('../site3/form2.html#SiteSearched');
You can't nit pick specific pages in subsequent pages, as I told you. You can only use this:
$.mobile.changePage('../site3/form2.html');
And jQuery Mobile will show you first data-role="page" occurrence inside form2.html page.
Read more about this here and here.
I've got a two page jQuery mobile app, and within the init function, the following code..
Call to the init function
$(document).on('pageinit', function(){
MyPages.init();
});
init: function() {
$('td[id$="drops"]').each(function() {
console.log("Element: " + $(this).attr('id'));
}),
};
I have elements in page one that match the above, such as '#early_drops', '#late_drops', etc. These elements do not exist on page 2, but when page 2 loads, the elements are displayed in the console just like when page 1 is loaded. What am I missing here?
Thanks very much,

By default jQuery loads pages using AJAX into the existing page in order to allow the animated transitions. If you don't want this you just need to 'turn off' the AJAX loading.
See description here: http://view.jquerymobile.com/1.3.2/dist/demos/widgets/links/
Links that point to other domains or that have rel="external", data-ajax="false" or target attributes will not be loaded with AJAX. Instead, these links will cause a full page refresh with no animated transition. Both attributes (rel="external" and data-ajax="false") have the same effect, but a different semantic meaning: rel="external" should be used when linking to another site or domain, while data-ajax="false" is useful for simply opting a page within your domain from being loaded via AJAX.
You can also disable AJAX across the entire app by default using global configuration: http://api.jquerymobile.com/global-config/
I am currently building a website containing lots of links to different sections of my website (also known as navigation). Lets call those links and their corresponding pages link1, page1 , link2, page2, link3, page3 etc.
The general code for them is this:
Link1
Link2
Link3
I want the user to click each link to move to the corresponding webpage and it works as supposed to. The problem is that I want the links to do nothing when the user is on the same page as the link they clicked (meaning it will only reload the page). Let me make this clear by using an example:
Current use: User is on page1. User clicks on link1. The browser will reload page1.
Desired use: User is on page1. User clicks on link1. The browser will do nothing.
TL;DR Essentially I am searching for an if clause. I have read there is no if clause in HTML simply because it's a markup language but what is another way to implement this? Thanks for your help.
The best answer I have found without the need to use JQuery or JS after munching through SO is this, answer made by Matt Crinklaw-Vogt:
Add a /#!. This will prevent the scrolling to the top and will also prevent the page reloading.
Code:
Link1
Original answer:
How do I stop a web page from scrolling to the top when a link is clicked that triggers JavaScript?
I'm not sure I like it, but you could use an empty bookmark to do this...
Link1
If you aren't on page1, it will load page1, but once you are there, it won't do anything.
Link2
OR
<a onclick = "return false;">Link2</a>
That cancels out the load.
On page load, you could use JS as follows
Link1
JS:
document.getElementById("link1").setAttribute("href", "#");
You can use javascript to compare the current url to the anchor link, and if they're the same, prevent the default click event. Using jquery:
var url = window.location.pathname,
urlRegExp = new RegExp(url.replace(/\/$/,'') + "$");
$('a').each(function(){
if(urlRegExp.test(this.href.replace(/\/$/,''))) {
$(this).click(function(event) {
event.preventDefault();
});
}
});
I load jQuery Mobile on my site when I am only on a mobile touchscreen device. When I do though. It messes up everything. For example, select menus don't work quite right, as well, the words "loading, loading, undefined" appear at the bottom of the page. I know I am missing something but do not know what.
Any ideas on what I could be missing?
Thanks
EDIT: Okay, So I took out all scripts that I am running except for jQuery and jQuery Mobile. I call jQuery first, then jQuery Mobile. It still breaks aspects of the site.
What it breaks:
- I cannot navigate to any other page via the navbar, if I click on a nav item, and look in the url, the correct url appears (with a # in it) like: /#/about-us/ Then, it just redirects to the home page and the page goes white
Select menus have weird results. It prints out whatever is in the select right beside it. And if you in landscape mode on the ipad and you click on the select, it sends you to the bottom of the page (weird).
it prints out 'loading' twice and 'undefined' once at the bottom of the page
All I have for scripts are jQuery and jQuery Mobile. I should also mention that I am using wordpress so it might have enqueued some other scripts (I have deregistered Wordpress' version of jquery and enqueued my own)
Anyone else experiencing these problems?
jQueryMobile replace your normal links with Ajax one, so every page can be loaded by the ajax, text on docs page:
(..) Ajax is used to load the contents of each page into the DOM as you navigate, and the DOM ready handler only executes for the first page. To execute code whenever a new page is loaded and created, you can bind to the pageinit event. This event is explained in detail at the bottom of this page.
If you want to disable single link to be loaded by the ajax you should write something like this:
<a href="/some_page" data-ajax="false" >link</a>
or do it globally:
$(document).bind("mobileinit", function() {
$.mobile.ajaxEnabled = false;
});
jm also does replacement on other elements so you should try using data-role attribute, for example:
<select id="test" data-role="none">
to disable replacing this element.
For those like me where
$.mobile.ajaxEnabled = false;
did not work and the whole page layout seems still broken:
For me this one works (- set it inline before loading the jquery mobile file):
<script>
// Preload configuration
$( document ).on( "mobileinit", function() {
$.mobile.autoInitializePage = false; // This one does the job
});
</script>
Furthermore if you want to disable jQuery mobile automatic link and form handling via ajax, set (as dvk3 said) ajaxEnabled to false and pushStateEnabled to false as recommended:
$.mobile.ajaxEnabled = false;
$.mobile.pushStateEnabled = false; // Recommended is false, when ajax is disabled
For further information see: http://api.jquerymobile.com/global-config/
I'm using v1.4.5
Same happened to me by mixing mobile with other frameworks. Fixed issue but getting custom build of jQuery.mobile. My case was that I needed swipe for touch devices only so used custom min file and nothing was broken after that.
It really depends if you need jQuery.mobile or you need just a certain functionality, Widgets, events? Use custom version that you can build yourself.
You can make and download yours here : http://jquerymobile.com/download-builder/
I hope it worked for you too guys!
I want to do something every time a page loads. It's something that fixes the way the mobile site looks on different devices so it needs to happen on AJAX loads too.
At the moment, I've tried the traditional $(function(){ /*...*/ }); approach but that only works on the first load, and not subsequent AJAX loads.
I've been looking for the right event to bind to but I'm failing pretty hard.
You can use JQuery to bind to each "page" (div's set with the data-role=page attribute) and use the pageshow event (there are some others as well: pagebeforeshow, pagehide, pagebeforehide).
$(document).delegate('.ui-page', 'pageshow', function () {
//Your code for each page load here
});
http://api.jquerymobile.com/pageshow/
Note: this answer was written for jQuery Mobile 1.0.1, see the documentation link above for more information.
You can listen to the pageshow or pagecreate event and do your work there.
