Ive read alot about jQuery Mobile and Knockout.js not playing nice together. Should I ditch knockout.js for my mobile pages and stick with jquery mobiles javascript to handle my view updates? Is there a better option?
They work fine together. You will need to manually invoke jquery mobile's various widget methods if you are dynamically generating markup with ko's templating or if you are manipulating CSS or other properties. Custom bindings are another valid approach.
$('#myButon').button('refresh');
$('#myListview').listview('refresh');
$("#myCheckboxList").checkboxradio("refresh");
If your markup is static other than text values, it should be no-brainer.
I just started a new project for mobile website, JQM and KO are combined, they are great frameworks and I've never seen any big issue with them.

I'm using jQuery mobile to build a simple web app and I want to add a navigation bar common to all pages.
I've found this great example, which led me to this question: do I really need the attribute data-role="navbar"?
Because it adds unnecessary html and css to my code, obligating me to override all these unnecessary styles.
Thank you
I haven't seen the need for data-role="navbar". This page here might help: jQuery Mobile Data Attributes.
It looks like it might only be needed for styling.
I am starting a jquery mobile/phonegap application. And would like to know if there is any way I can keep my code in seperate files so it is easier to manage. From all the reading I have done on jquery mobile it looks like all of your pages are in one file and are just seperated by divs like <div data-role="page" id="page-one"></div>. I guess I could try to make some type of a makefile that concatenated them all together, but it seems that most apps are pretty lengthy that they should have a solution for this. Keeping all the code in one file just seems impossible to maintain.
JQuery demo, three pages, all one source file:
http://demos.jquerymobile.com/1.1.0/docs/pages/multipage-template.html
You can just use normal links with jQuery mobile:
http://demos.jquerymobile.com/1.4.0/navigation/
It will "hijack" the link and use transitions to give you a native like animation. As Flatlineato pointed out you need to make each page confirm to the required markup, and you'll need to repeat your headers/footers etc on each included page.
Or you can use more complex solutions to dynamically change the content of your page, which can be stored in multiple files, like this other SO post:
including the header and footer in jquery mobile multiple page site
But I would also agree with Leo and say the jQuery mobile isn't the best choice for Phonegap, it's not that well optimized, and runs slower in the Phonegap webkit view than it does in native safari.
I've also switched to a custom navigation system and dropped jQM early on in my Phonegap development, but that was over a year ago, more recent versions may work better.
I think my personal API is what you are searching for:
https://github.com/charnekin/api
Demo example:
http://yopo.es/cordovapi/
jQuery Mobile allows you to have the pages in separate files. Obviously in each file must conform to the structure of the markup pages.
To point to another page in the link instead of the id you specify the correct file name. If the file then you enter multiple jquery mobile pages must also specify the id.
i'm totally a beginner of jquery mobile, i'm wondering how does everybody build the UI?
by html markup or writing pure code?
if it's by html markup, then if i have a complex applicaiton , then i'm gonna have a very long html file with a lot of pages, how do you deal with that?
if with pure code, i don't find it easy to create widgets, the only i found it just to put the pure html code into a jquery object wrapper. it's not very object-oreinted, i want some simple ways like: var $aButton = new button( );
i had ios native app development experience, normally i write the ui with pure coding. i'm just wondering if there's way to build ui with pure code?
There's no official way to build the UI in pure code but no one stops you from writing your own "code generator".
Be warned:
Writing HTML is the easier way to do, because JQM will do all of the UI-manip.
I'm working on a UI generator for JQM which
will be released opensource. Still a lot to do but it already works more or less - see http://officejs.com
Check the erp5loader.js file which generates the whole app - there is only an empty index.html.
The factory section contains all methods necessary to generate JQM UI. The JSON files loaded show how to generate static and dynamic widgets as well as how to hook into navigation and global action bindings
Roll your own or wait until we are releasing ours :-)
I'm preparing a very basic Backbone application using jQuery Mobile for the UI and Backbone (with RequireJS) for the rest.
I used the following project as a base:
https://github.com/fiznool/mobile-backbone-boilerplate
And used Christophe Coenraets guide for using jQuery Mobile along with Backbone:
http://coenraets.org/blog/2012/03/using-backbone-js-with-jquery-mobile/
And found a couple of good information, for example in here:
jquery mobile require.js and backbone
However, I'm having a lot of issues with new generated content and styles: more with pages that have more than one uri segment (for example: /movie/1).
My method that changes the view looks like the following:
var changeView = function(newView) {
newView.render();
newView.$el.addClass("ui-page").attr('data-role', 'page');
$(container).append(newView.$el);
$.mobile.changePage(newView.$el, {changeHash:false});
};
The page is actually changed, but it looks without any style. I found a solution by using the following code on the jquery.mobiile.config.js file:
$(document).bind('pagechange', function(e) {
$('.ui-page-active .ui-listview').listview('refresh');
$('.ui-page-active').page("destroy").page();
});
However, the styles are applied really late (after the page is rendered, like 500ms after).
Is there a better solution for this?
Well, I opted by removing jQuery Mobile and just style my components on my own.
I love jQuery Mobile and I used it in a couple of applications before, but the decision was more likely because the application felt too heavy when using jQuery Mobile and I just needed like 10% of jQuery Mobile.
Does anyone know of any good tutorials, blogs etc on usage of the jQuery UI CSS Framework. I have read everything on the Jquery website but the documentation is quite poor. Via google I have been unable to find any additional information other then what is on the JQuery website. I know some good material must exist, but does anyone know where it is?
