问题 I'm creating a web application with desktop and mobile versions using ExtJS and Sencha Touch. ExtJS 4 and Sencha Touch 2 use an MVC approach, and Sencha Touch 2 incorporates "profiles" for different devices (iPhone, tablet, etc.). ExtJs 4, however, has no notion of profiles. Is it realistically feasible to for dependencies for desktop, iPhone, and iPad versions of the app to live under one vhost, in the same app directory hierarchy? Or, is it generally more acceptable to use different vhosts

问题 Ok, I'm still getting the hang of asp.net and the MVC framework and converting my knowledge over from classic ASP and VB - so please be gentle. I've got my first view (/home/details/X) functioning well thanks to previous help pointing me in the right direction, now I need to add data from multiple tables and queries/views to the MVC view (I hate that SQL and MVC both use the word view for different meanings). I'm not looking for someone to write the answer for me (unless they're feeling

问题 Is it possible to implement client-site validation for custom ValidationAttribute, which is used in Class scope? For example my MaxLengthGlobal, which should assure global max limit for all input fields. [AttributeUsage(AttributeTargets.Class)] public class MaxLengthGlobalAttribute : ValidationAttribute, IClientValidatable { public int MaximumLength { get; private set; } public MaxLengthGlobalAttribute(int maximumLength) { this.MaximumLength = maximumLength; } public override bool IsValid

问题 I'd starting to learn JSF, but first I'd like to understand the big picture of it as an MVC framework. There are several answers with many upvotes explaining what are MVC layers in JSF, but they usually contradict themselves. BalusC's answer: What components are MVC in JSF MVC framework? In the big architectural picture, your own JSF code is the V : M - Business domain/Service layer (e.g. EJB/JPA/DAO) V - Your JSF code C - FacesServlet In the developer picture, the architectural V is in turn

问题 Hi I have worked with JSF which is a component based MVC framework . I know a lot of web projects use Spring as their technology and Spring falls under the category "action based UI framework " . I want to know what is the difference here ? Which one is more advanced and gives more flexibility to the users ? Some pros and cons ? 回答1: Component Based Web Framework is a way of implementing Web (HTTP) based applications similar to thick-client applications where user operates on GUI controls

问题 I want to test the OnException , OnActionExecuted event of an MVC controller. If I use mock like this: var httpContext = MockRepository.GenerateMock<HttpContextBase>(); var request = MockRepository.GenerateMock<HttpRequestBase>(); httpContext.Expect(c => c.Request).Return(request).Repeat.AtLeastOnce(); request.Expect(r => r.IsAuthenticated ).Return(true).Repeat.AtLeastOnce(); var controller = new MyController() ; controller.ControllerContext = new ControllerContext(httpContext, new RouteData(

问题 I have looked over lots of examples of ExtJS 4 MVC, and they all pretty much show the same thing: The application creates a viewport, loads in a view, and has a 'controllers' defined, which init's the controller: Ext.application({ name: 'AM', controllers: [ 'Users' ], launch: function() { Ext.create('Ext.container.Viewport', { layout: 'fit', items: [ { xtype: 'userlist' } ] }); } }); Thats great, but now let's say in my application I want a button contained within my view to open a whole new

问题 Ok, this has probably been asked before but i cant find a definative answer. Where in the MVC pattern should validation of input happen? I would like to say that things like empty fields and basic general validation should happen in the controller and that rules as lengths and valid characters of for example usernames / passwords etc should happen at the model layer. However, this means spreading this burdon around the application which surely cant be good either? Sorry if this question is
