I'm looking for a NodeJS MVC framework that allows rendering partial views on client side using Ajax (without whole page refreshing).
As far as I know, you can declare partial views on server with almost any Framework (Express, Sails...), but this will lead to refresh the whole page even if there's only a small portion of your page that really changes. This problem doesn't exist with a SPA Framework (this one would just load the partial html file in a container via ajax).
I believe Microsoft ASP.NET MVC was able to handle this case, by comparing the previous version of the page with the new requested page, and just returning the portion of the page that really changed. This may be time and CPU-consuming but it just works.
Is any Node MVC Framework managing a similar thing today ? Or is it mandatory to use an SPA Framework when a reactive user interface is required (without any whole page refresh) ?
Thanks in advance !
sails.js! It supports partials as you requested. You don't need to refresh the page, if you send ajax-request or handle the stuff via websockets dynamically.

Will the new JSF 4.0 be free of the full view getting rebuild on server side after each ajax request?
This rebuild is very time consuming on pages with many components.
Or exists a way to avoid building the whole view after Ajax call?
Maybe cache components on the server side, they will not change by Ajax?
I was looking for the solution in Omnifaces, tried with o:cache, but does not work. Every time after ajax request all components are rebuild.
When we don't use ajax, browser's backward and forward arrows provide navigation to previous (and next) pages. Although when we use ajax to retrieve information (to have a single page application), we loose previous pages and browser does not know anything about the history of navigation.
What is the best solution for managing the history of previous pages when we use ajax specially in MVC.NET web applications context.
Thanks
The history api of html5 is the key. See:

I'm using tastypie + django + backbone.js . My application should be usable by more than one user at a time.
What I want to do is to show all users "live" changes on the database without having the users manually reloading the page.
Anyone around to point me in the right direction?
Thanks
To get this working in all major browsers you will have to periodically send an AJAX request to your server asking if any changes have occured.
In modern browsers you could make use ob web sockets to setup a PUSH service where the server can push those changes to your application or simply notify you about it.
(If you are using Backbone as an MVC framework anyway you might as well step back from the idea of reloading the page and just request your data using AJAX and use Backbone's View component to render your data into HTML elements)
I am working on a mobile website in ASP.NET MVC3. I have a page where i have search bar in my header. this header is coming from my Layout page which is common to all other Views. And inside my specific page, I have page specific content(forms).
For my Customer/Add action, I return the Add View of Customer which is strongly typed to my CustomerViewModel. I will have form tag in my Add View which will be posted to HttpPost Add Action method when form gets submitted. That is fine. My question is how will i handle the search box content ? I believe only one form is allowed in the page.So if i have a SearchViewModel which is binded to my Search View(Partial), It is going to be 2 forms in my page. So i can not do that.
I can handle the search part by reading the content in java script and calling another action to get Search results.Is that the only way to do that ? I am worried about those devices where java script is disabled. What should i do ? Please advice
No. You can have more than 1 form on the page. In fact, here you should. Your Add Customer page should submit to 1 action method, but your search form should submit to a different action method.
If you are familiar with webforms, that framework only allows you to have 1 form on the page, but not because HTML requires it. Webforms requires it because it is the only way the framework can carry all of the data from various server controls across POST requests (using ViewState). Webforms has historically not been very HTML or HTTP friendly.
You just can't have forms nested within other forms in HTML, but it is completely legal (and recommended in MVC) to have more than 1 form on a page.
As for AJAX, I would not worry about devices that do not have javascript enabled. There are only like 6 or 7 people on the planet that don't have javascript on their web devices, and if someone disables javascript, they won't be able to experience 99% of the rest of the web anyhow.
I am looking to implement a live search in my MVC app similar to this site when you type in a question and results come up that are similar or like the search on http://www.krop.com/
I have the search code all working and results updated. I just need to know how to add the AJAX to the MVC framework (I know this site was built using it) so that when I type the results are updated.
I had this all working in normal ASP.NET Forms app.
what you need to do it attach to Jquery onchage event handler, and then call some ajax method of jquery ($.load , $.ajax etc...) and the information from a specified controller. asp.net mvc controller can return json results so you can later manipulate it in your javascript code.
if you have any other questions go ahead and ask.
An ASP.NET MVC site will have AJAX and JQuery available by default.
