do.This picture may help us understand MVC better. In addition, it has been mentioned that the C layer does not have any business logic. This point I also have different views, it depends on you less serious, if true seriously,C layer and M layer interaction, M layer is responsible for the main business logic processing, mutual interaction, C layer to know these logic, so the inevitable C layer also need a small part of the business logic to do suppo

. So displaying the 404 page is very normal.Let's say we want to show a detailed page.Need to add the corresponding request access method in the address bar the action method is able, that is, the address of our form submission/login The result can be out.three, control three layers:A very obvious difference: compared to the three-layer, MVC schema pattern, there is no Aspx.cs file. This is what the MVC mod

In recent days have been learning javaweb but always broken, and today finally have time to learn about MVC under the query Mode.First of all, let's look at what MVC is.　　MVC is the abbreviation for model-view-controller, the Model-view-controller. It is a design pattern, it is the application is divided into three cor

Use jQuery to form Ajax requests: 1) Create an AjaxExamples project and add the CustomAjax controller: namespace AjaxExamples.Controllers{ public class CustomAjaxController : Controller { public ActionResult Index() { return View(); } public ActionResult PrivacyPolicy() {

tree with third-party toolsWhat I've written above is a little fun. There are many places that are imperfect and irrational, and MVC implements tree third-party tools already have the very best to help us.Here we recommend an open source is the Telerik tree------Introduction and connectionBasically all of the operations are encapsulated in the inside of the ~ very convenient and there are many other controls ~Also, recommend that you look at the sour

listed, there are contentresult,fileresult,jsonresult and javascriptresult. 5. There are several ways to pass data from action to View: View Model Object: // action Public ViewResult Index () {DateTime date = D atetime.now; return View (date), // view Gets the @model DateTime @{viewbag.title = index " ;} the day is : @ Model.dayofweek ViewBag, which is a weak type of dynamic, is parsed when the program is run and is a new feature in MVC3, only vali

architecture, that is, on the basis of display and logical separation, and then the logic of all the data processing modules are extracted separately, in the required functions to debug.Data processing units in the M-model projectV-view Project for result presentation units (template files)A unit in the C-controller project that is responsible for the overall process scheduling of a functionAt this point the browser only needs to interact with C.Summary: The concept of

need to be validated. Don't worry ~ Lazy programming guys don't do stupid things like that. If all the methods in a controller need to be validated Then we can put the label on the controller class uniformly, as follows: So all of the action methods in the controller will be validated So what if each controller class has to be validated. This time we'll need to open the App_start folder. Have you seen a Filterconfig class? Double hit Open FilterConfig.cs We can add a global filter here, such a

pattern that divides an application into three core modules: models, views, and Controllers , each of which handles its own tasks.③ Detailed Description:I. Model (MODELS):(Database + POJO) Common Java class, and Access databaseThe > model is the main part of the application, and the model represents the business data and business logic;> A model can provide data for multiple views;> Because the code applied to the model can be reused by multiple views only once, it improves the reusability of t

Since the new project plan to be taken up is being developed with ASP. NET MVC3, I have been reading the relevant book or article for some time recently. Because before in the university has also studied MVC2 development, has done a few simple MVC2 small test project, but after the work mainly still develops the WebForm project, therefore the MVC thing also gradually forgets.After this period of time of the system

framework is applied in the system architecture is an important part of software architecture design.Definition of the frameworkIn design mode, the Gamma-like framework gives a clear definition: The framework is a set of working classes that build a reusable design for a particular type of software.A framework is a set of collaborative artifacts (Component) that can handle a range of issues in one or more problem domains (domain). The framework emphasizes the reusability of software design and

help you understand its MVC model and learn the most basic layout. Let's talk a little bit about it. Let's take a look at the final implementation effect of the case: The webpage layout consists of the top title, left menu, and right topic content. Here we have a preliminary impression on the layout of the case, so that we can learn more in the future.After understanding the final results of the project, let's take a look at the final file struc
