I'm working on a asp.net mvc2 app. I have been using jquery to do various different things in all of my views. They are work from a regular browser quite well. But I'm trying to figure out a good way to get the functionality working with browsers with javascript disabled (like mobile browsers). Is there a way to define a whole different view for non javascript browsers?
A specific example of what I'm trying to do is, I have a <button> with it's onClick calling a javascript that does $.post() to a controller.
What's a good way to make it, so, it works the way it works right now (doing ajax calls) with regular javascript-enabled browsers and it a also works with javascript-incapable browsers, doing a full postback ?
Thanks
I use the unobtrusive javascript approach; get the app working without JavaScript, then add in extensibility with JQuery so that the app will work when scripts are turned off, or if the JS fails to download.
Same approach I believe that #James Kolpack is talking about. This is the true failsafe approach. While you can detect the support of JS by the browser through Request.Browser, this isn't accurate to most of the possible scenarios.

If I'm already using jQuery Mobile -- is http://css-tricks.com/add-page-transitions-css-smoothstate-js/ (http://weblinc.github.io/jquery.smoothState.js/) possible / worth it to implement?
I really don't see a benefit of using jQuery Mobile with smoothState.js. jQuery Mobile already can do everything smoothState.js can, you only need to learn how. Though smoothState.js has everything better described, plus you don't need to use gazillion different page events. But to use them both you would need to turn off jQuery Mobile Ajax handling.
Basically I would like to see smoothState.js approach used inside jQuery Mobile framework.
My advice stick to jQuery mobile if you really need its UI, for everything else use smoothState.js, of course if seamless navigation is something you desire.
I am developing a hybrid mobile app using jQuery Mobile and AngularJS.
I decided to use a mix of the two for the following:
jQuery Mobile
good UI features
not too heavyweight (compared to Sencha Touch, for example)
AngularJS
good performance and resource management (caching, asynchronous requests)
personal experience
I have little to no experience with jQuery Mobile and, as I was learning, I noticed a potential conflict between the page navigation models of the two.
Should I use only one ?
If yes, which one is better suited for my needs ?
Are there any gotchas with this setup ?
Many thanks.
You can't compare them to each other.
Angular.js (like Backbone, Ember eg.) are MV* Frameworks (for SPA) which used to render html templates/views directly in the client instead of server. So you have a lot of application logic now in your frontend and this Frameworks are made to make your life better, coding this.
jQuery Mobile on the other side is a pure widget/plugin library. The AJAX navigation plugin load pages (something static, like html) into the DOM via AJAX. So you have to pre-render this pages on the server somehow.
If you started to build a SPA with Angular it doesn't make sense to use jQuery Mobile's AJAX navigation at all. (If it's a native mobile app you have no server anyway.)
Sure, you won't get far without an UI component library so use one of your choice (eg. jQM) but work with Angular's directives to init the plugins/widgets correctly on your DOM elements since a $(document).ready(...) or a $(document).on( "pageload", ... ) doesn't know anything about your Angular views.
Take a look at following projects:
http://angular-ui.github.io
https://github.com/angular-widgets/angular-jqm
This has been already addressed in HERE
Basically the article states that trying to intercept the navigation from angular can be painful, so leave all the routing jqm
I'm doing an app with jQuery Mobile and Angular.js. Cause we have some issues using both libs, exists an adapter that do "teh job".
So I'm trying using routeProvider to route my pages. But I still can't render pages using this.
Here plunker if u can help show me the way.

Thanks in advance!
I ran into a similar problem and maybe what I learned might help you. It comes down to the differences in the way angular and jquery go from one page/section to another (routing).
First, the basics: angular routes by inserting a chunk of html into your view, then on whatever click/action/etc, removing that html from the view and adding a new chunk of html. Essentially you're on the same page all the time; it's just the included html is changing. In contrast, think of jqm as loading up all the html into the same page, with those html chunks as divs. Instead of removing html chunks and replacing them (via routing), it's just turning divs off and on. (There are multi-page jqm apps but SPAs really highlight the differences.)
My suggestion is to pick which set of features you really want: angular's minimalistic loading (only as you need it), or jqm's flashy transitions and other built-in features. If you've got a massive app with a lot of data on every page, you might want to bypass jqm and use angular alone, and see what you can do with angular's new animate functions. It'll mean you'll need to build (via CSS or javascript) duplicates of the jqm features -- and from what I've seen, you can get close but it won't quite be as pleasantly streamlined as jqm.
If the jqm built-in features are what you really want, then skip using angular's routing. It'll just introduce all kinds of complications, anyway. Set up your pages using jqm's pattern, and use angular only where you're dealing with data.
What I've found works best is to treat it like it's a jqm app overall, and only add angular into the sections where you need it. After all, you don't have to add ng-app at the html line; you can add it into a single div as needed. Since jqm is happiest as a system-wide kind of thing, while angular is just fine being confined to pieces within a system, so far I've found jqm-whole and angular-parts to be the simplest way to get the best of both worlds.
As I am newbie to JQuery. I have certain questions in mind regarding JQuery.
Can I make complete website with Jquery?
Means in ASP.Net website we use Server Controls to design page, Can we make all this functionality on .ASPX page using JQuery?
If yes, then how to handle server side events?
For designing .ASPX pages, what we prefer to use? JQuery standard controls or Plugin?
No. JQuery is not a server-side framework. It's a client side DOM Manipulation domain specific language and API that enables client-side code to work cross-browser, and includes a variety of utility and helper functions for AJAX, deferred callback resolution, and generic functional programming.
In short, it is not meant to replace your server-side code.
The jQuery framework is only a javascript library which means it can only handle events or actions on the client-side. It doesn't matter what backend you are using for your website (PHP, ASP.Net, Python), javascript only works once the page has been rendered and sent to the browser. Try reading up on the docs for jQuery here: http://docs.jquery.com/
If you have any questions specifically about jQuery programming, we would be more than happy to answer them.
jQuery Mobile is working for my site but slow. Cause of the slowness turned out to be jquery. We searched an alternative but most of them still uses javascript/jquery.
Question: Is there any other framework for mobile with better performance?
Considering Javascript is the core language all web browsers use for programatic changes, unless you want to only change the Visuals via CSS and what it has to offer, I believe you are stuck.
Take a look at Zepto: https://github.com/madrobby/zepto
It still uses JavaScript but with a really small footprint.
