Description

  The present invention relates to a display screen control method, a display screen control program, and a display screen control device that control screen transition on a stateless protocol such as a web page.

  In recent years, an MVC (Model View Controller) architecture has become widespread in systems that dynamically display web pages. This is a technique adopted as a standard in J2EE (Java (registered trademark) 2 Platform, Enterprise Edition), and is intended to separate the screen interface and business processing. It is now possible to design a system using web pages.

  In the MVC architecture, the controller receives a request from a user and calls a model. The controller has knowledge of these in order to connect the view and the model. A model is synonymous with a command object and has a class name (class name) and a method (method name). The model performs business functions or defines behavior for data. The model is unaware of the controller and view. The view draws the screen based on information from the model.

  In the conventional MVC architecture, a method for controlling screen transitions using two parameters of a module name and a result is known. Here, the module name and the result screen are associated with each other, and a screen to be transitioned with execution of processing related to the module name is determined.

  For example, if product search, reference, registration, addition, and change functions are possible in ordering products, each of the module names of order search, order reference, order registration, order addition, and order change will succeed. In this case, a table in which information for specifying a screen to be transitioned in the case of failure and information for specifying a screen to be transitioned in the case of failure is used is associated.

  In addition, in the prior art, the screen being presented is shown in order to control fine screen transitions with a simple structure and flexibly respond to screen transition changes and screen additions without changing modules. The current screen ID, the command name that identifies the command object corresponding to the module that can be executed on the screen, the method name that identifies the method called by the command object, the result of the processing caused by the execution of the command object method, A result screen ID to be transitioned is defined. When “Http Request” including a parameter indicating information specifying a command object and a method is received in relation to a certain screen, in response to the reception of the request, the definition table is referred to and the certain screen is set as the current screen ID. The screen ID to be transitioned is specified according to the processing result together with the information specifying the command object and the method, and the screen transitions (see, for example, Patent Document 1).
