I am using the DateBox ( http://dev.jtsage.com/jQM-DateBox/ ) plugin for a page with the latest build of JqueryMobile but am finding an odd bug.
When I open my app on index.html and navigate through the pages to the page with the date picker is I get this - http://cl.ly/19022K40472e3k0D0D2H
However if I go direct to the page via the address bar it works fine and shows up as it should.
So just wondering is anyone else having problems with this? Or any idea how to fix it?
Also I might add does anyone know how I can have the current date show in the text field?
Thanks.
1) Looks like it is a problem with the css of datebox not being loaded properly.Are you loading the CSS of datebox in index.html?.In that case,when you directly go to the page with the datepicker,CSS might not be loaded.You can check if datebox css is loaded by using firebug for firefox or the in built developer tool in Chrome/Safari.(Check the resources tab to see all the loaded resources)
2)Check this example - http://jsfiddle.net/BNsPB/. In this example I wrote the code in document ready,in your case you might have to write it in pageinit or pagecreate event handlers
After checking your actual code I think you have to add the above code snippet in the pageshow event handler like this:(Assuming bookingPage is the id of the page)
$("#bookingPage").live( 'pageshow',function(event, ui){
var today = new Date();
var todayStr = today.getFullYear()+"-"+(today.getMonth()+1)+"-"+today.getDate();
$('#mydate').trigger('datebox', {'method':'set', 'value':todayStr});
});
});
You need to load the files in the actual file that your site navigates to in the first instance (index.html presumably). It sounds like you have only referenced the CSS and plugin code in your date picker page, but in default mode jQM uses an ajax hash-based navigation system, so you need to reference assets in such a way that they are available right from the get-go.

I previously used javascript dialogs for confirmation on a mobile web app, but am now trying to switch over to using the new popups feature in JQM 1.2. My initial test doesn't work - no popup appears and I'm simply redirected to the anchor I'm trying to call.
My test code is simple, albeit a bit obfuscated because I'm using haml:
%a{:href => "#popupBasic", :"data-rel" => "popup"} Show popup
%div{:id => "popupBasic", :"data-role" => "popup"} Basic popup div
That said, I don't believe the haml is causing the issue based on reading the final HTML output. Both elements are at equal depth and contained within the element.
In addition, the div does "popup" without issue when I use the following at the console:
$( "#popupBasic" ).popup( "open" )
That makes me believe that the issue lies somewhere in the link or the URL handling. When I do click the link, it instead takes me straight to
http://localhost:3000/#popupBasic
Any ideas on how I should be handling the URL differently so that it shows the popup as intended?
After realizing the problem was probably some part of my Javascript, I went through and tried turning off each bit of javascript individually, until I figured out that the problem was with this in my application.js file:
$(document).bind("mobileinit", function(){
$.mobile.linkBindingEnabled = false;
});
which prevents all anchor click handling. Obviously now that I've removed this code the anchor links are working properly. Of course, that means I'm now left with trying to figure out why I added that in the first place and what I just broke by removing it...
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.

I am working on a web-app for my employer and I am using some jquery. I am fairly good at PHP, but lost in jquery. My question is as follows:
I have a a working tabs page that loads a monster PHP page when it first loads. I need to make sure that this particular tab only loads when the page is called (the first time only). I have the initial tab cached, and if you click on another tab everything is fine. The problem is that when you click a link from within the tab it reloads the monster PHP page. Here is the code:
$(document).ready(function() {
$("#frame").hide();
$("ASA").tabs({ cache: true });
$("#tabs").tabs();
});
function CH(ids){
$("#tabs").tabs("select" , "#CH");
$('#CH').load('test.php?id='+ids);
cache : true
}
function onIFrameLoad() {
$("#loader").hide('slow');
$('#frame').slideDown('slow');
}
Function CH is where I am having trouble (I guess). I have cache:true in there, but it was a shot in the dark. The only tab I want cached (at this point) is the main tab (ASA).
Thanks for the help.
The correct syntax for using cache is
$( ".selector" ).tabs({ cache: true });
However, this would work only if each tab is loaded remotely (ie. ajax). There's no reason to do this if you use the original HTML structure given by the documentation, because all of the contents for all tabs are loaded all initially. You also cannot (as far as I can tell) turn caching on for individual tabs.
What we really need to see is what HTML structure you've got for this. Also, the selector $("ASA").tabs({ cache: true }); probably won't work, as ASA isn't a valid HTML element.
Ok... so it is a complete hack/workaround, but I have a solution. I would love to hear the RIGHT way to do it if someone can direct me, but here is what I did:
In each tab I pre-load a blank iframe.
My links all now point to iframes instead of functions.
Each iframe calls a function to "select" its tab from the parent.
Result is that after load the tab is shown and the main tab is never refreshed.
Again, I know it is a hack, if you have a better way please let me know.
I added the following code to change the hash to the tab name:
$("#tabs > ul").tabs({
select: function(event, ui){
window.location.hash = ui.tab.hash;
}
} );
This works fine in FF3 but in IE7 it moves down the page (depending on the tab selected anywhere from somewhere near the top of the page all the way down to the very end of the page).
I tried changing it to:
$("#tabs > ul").tabs();
$("#tabs > ul").bind("tabsshow", function(event, ui) {
window.location = ui.tab.hash;
})
This leads to identical behavior in both IE7 and FF3, which moves the page down to the top of the selected tab.
I would like the tab to be changed, the hash to be updated, but the page not moved at all, which is how it works in FF3 in my first example, but not in IE7.
Thanks.
Notes: JQuery 1.3.1 / JQuery-UI 1.6rc6
If there's an element on the page that has the same id as what you're setting the hash to, for instance you're trying to set the browser hash to #cars and there's already a div#cars on the page, the browser will scroll you down to where that div is.
To my knowledge, there are 3 possible workarounds
1) Change the browser hash to something else such as #thecars.
2) Change your existing markup in some similar manner.
3) On some event, changing the id of your similarly named markup, then changing the browser hash, then rechanging the name of markup back to it's original value should also theoretically work. This is obviously a bad and slow workaround, just thought I'd mention it.
You could try having a "return false;" after you set the window location but I can't be sure.
Unfortunately, your problems won't end there. There are other issues with navigating back and forth across multiple browsers--nothing may change, page may reload, page state might be mangled, javascript may get reinitialized etc.
You may want to have a look at Tabs v2 which uses the History/Remote plugin though it has not been updated for jQuery 1.3+.
This demo is easier to understand. If you look at the javascript source, you'll notice the use of iframes to handle states.
There is also the History Event plugin and the jHistory plugin to achieve what you want.
Would like to hear back how things turns out and what solution you went with.
What Chris suggested worked for me, had no clue even a div could link via the #. So my solution is quite simple, in the show: event handler, I do the following, it's not perfect in that back button won't be in history, but that's another job for BBQ history plugin. All my divs simply have id="tab-cars", id="tab-trucks"... strip out the 'tab-' part and put it into the url hash.
var name = ui.panel.id.substr(4);
location.hash = '#'+name;
