[Asp.net mvc] transmits form data in the view to the Controller. asp. netmvc
In the ASP. net mvc Framework, the data in the view is transmitted to the Controller, which is implemented by sending forms. The following three methods are used.
1. Read Form data through Request. Form
Form code:
1 @ using (Html. beginForm (
When ASP. NET MVC uses AJAX to request data, we typically return JSON or XML and parse the data for rendering, which can be cumbersome, request a partial action, return a partial view to render directly, and do not need to parse this step.Here's an example:Controller class: Public classHomecontroller:controller {// //GET:/home/ PublicActionResult Index () {returnView (); } [HttpPost] PublicPa
Strongly-typed helper methodsTemplate-Assisted methodsTemplate-assisted methods in ASP. NET MVC use metadata and templates to build HTML, that is: template helper methods can generate appropriate HTML tags at run time using any of the appropriate "editors" using data annotationsMetadata includes information about model values (name and type) and model metadata (added through data annotations or custom providers).Template-assisted methods have Html.dis
ObjectiveMVC at compile time, will not prompt the view in the error, we publish the project will be a prompt exception, the project will be a big headache, because each release requires at least 5 minutes, and finally received only one exception information, if the page is too large, such as the recent collation of code modified many of the underlying code, It's very inefficient to find out how to use it in a published way.WorkaroundReference URL: htt
One of the most blinding features of MVC is the ability to directly bind page and data models based on the model and view views, so we don't need to assign a variety of controls when we want the client to send the page, so we don't have to worry about how to render it. When the customer submits the form to the server, it does not need to do too much processing to directly call the form to model.So we can ac
It is convenient to organize the data from the background and pass it on to the page, because MVC itself builds such a requirement into the system. I just need to organize a list or IEnumerable variable in the background and throw the data model that needs to be passed in.Http://www.cnblogs.com/Wayou/p/pass_multi_modes_to_controller_in_MVC.htmlFor example, here we return 5 product information to the view to
MVC mode (Model View Controller):Model:dao modelview:jsp on the page to fill out the Java Code implementation displayController:servletRedirection and forwarding of requests:If the corresponding page of the target does not need to read any information from the request, the redirect can be used to prevent the form from repeating the submission;-----------------------------------------------------------------
I recently watched AngularJS and lamented its strength. At the same time, questions are raised. Does the traditional backend MVC not need the View layer. For example, laravel is used. You only need to upload data to the page. The template is no longer written. Or does the View in the backend still need it? I recently watched AngularJS and lamented its strength. A
Page layoutLayout support is provided in ASP., by default the layout file is saved to the _layout.cshtml,view directory in the/view/shared/directory with a _viewstart.cshtml file, the code inside @{"~/views/shared/_layout.cshtml";}Indicates who is the default layout file under this directory. You can add this code to a specific view file to modify the boilerpl
little.Well, it's really complicated enough, so ignore all the theories, native SQL, stored procedures, no layering, whatever.The business logic is written in the database, or written in the application, depending on the vertical load balancing, requiring wisdom and experience.The topic is the presentation layer, so it's not a question of whether the database should handle business logic.Summarize:When the interface element is more complex, try to create a viewmodel to combine the business clas
When compiling in MVC 4, an exception occurs in the View.
Preface
During MVC compilation, no View errors will be prompted. We will prompt exceptions one by one during project release, which will be a headache when the project is large, because every release takes at least five minutes, at last, I received only one exce
