问题 I've decided to use MVC Pattern on my site. So, now I use Backbone.js framework on my site. All actions on my site are ajaxy , so server only gets data from db, and saves data to db. Do I need to use MVC on the server side too? It's complicating all, isn't it? Or I may use MVC on client side, and have simple server api, that only fetches/saves data and makes some small server job? UPD: I understand that I should use Models on server side. But what are Views for on server side - if I render

问题 I'm beginning development of an app in extjs. I'm using the MVC approach, as provided in the extjs documentation. I have some dynamic data which needs to present the user with a set of accordion controls. I've got the data in a store, but I do not know how to dynamically create the accordion items (unlike grid panels, there doesn't appear to be a store data method). Here is my current accordion view code - with static items: Ext.define('BP.view.induction.LeftPage', { extend: 'Ext.Panel',

问题 Which do you guys prefer? I've been looking into both and there definitely seems to be some inconsistency in what people call them. I will try and jot down what the differences are and you can correct me if I'm wrong. MVC Model holds references to it's own observers (Views), on updates to the model it notifies observers. Views pass all events and messages to the Controller. Views update their content when they are notified by the model that a change has occured. View holds a reference to the

问题 As I am working on Asp.Net MVC Application, in my application I am using jQuery.POST method to submit a form. e.g. jQuery.post('/Product/Save', jQuery(document.forms[0]).serialize(), function (data) { alert('Product Added Successfully.); } ); In above code snippet, I want to pass another parameter.. let's say.. ProductID . So, the idea is, I want to pass both jQuery(document.forms[0]).serialize() and ProductID variable in jQuery.POST method , so I can get both Form and ProductID in my

问题 I'm using a QTableView with a subclass of QItemDelegate to control the look and feel of the tableview's cells. Each cell displays the name and status of a of an externally connected device, and as many as 100 devices may be connected at once. The name and type of each device is essentially static, updating very rarely (perhaps once an hour), but each cell needs to display a real time value of the device's input, which I currently poll for every 50 milliseconds. This value is displayed as a

问题 In MVC web development frameworks such as Ruby on Rails, Django, and CakePHP, HTTP requests are routed to controllers, which fetch objects which are usually persisted to a backend database store. These objects represent things like users, blog posts, etc., and often contain logic within their methods for permissions, fetching and/or mutating other objects, validation, etc. These frameworks are all very much object oriented. I've been reading up recently on functional programming and it seems

问题 Is there any best practice for PRG pattern with MVC? In this tutorial: http://www.theserverside.com/news/1365146/Redirect-After-Post the proposed solution requires 4 actions: Create_Item (POST) => "resets" the form and redirects to Display_Item Display_Item (GET) => shows the form (with temp data and errors if exists) Store_Item (POST) => try to save data to DB, if errors, save errors and redirect to Display_Item, if success redirect to Display_Stored Display_Stored (GET) => shows the item

问题 I hope to get some answers regarding having fx:include statements for each tab in a tabpane. I have managed with ease to get content to show up BUT referencing methods of the associated controller class simply gives me a nullpointerreference exception no matter how I structure it. The controllers of the included FXML layouts do not have neither constructor not initialize() methods, are they needed? I tried some different things but always got the same exception. What I simply did was add a
