Method and system for implementing multi-stage linkage pulldown menu based on MVC model

Abstract

The invention discloses a method for implementing a multilevel linkage pull-down menu based on an MVC model. The MVC model comprises a presentation layer module, a logic layer module and a persistence layer module. The method comprises the following steps: A, the presentation layer module selects and submits a first N-level linkage pull-down option to the logic layer; B, the logic layer module links the N+1 level linkage pull-down option according to the N-level linkage pull-down menu option; and C, the persistence layer module obtains the corresponding N+1 level linkage pull-down menu option from a database according to the N+1 level linkage pull-down menu and returns the corresponding N+1 level linkage pull-down menu option to the presentation layer for display through the logic layer. The invention correspondingly discloses a system for implementing a multilevel linkage pull-down menu based on the MVC model. Therefore, the dynamic option of the multilevel linkage pull-down menu is implemented, and the multilevel linkage pull-down menu has strong expandability and high maintainability.

Description

technical field [0001] The present invention relates to the technical field of software, in particular to a method and system for realizing a multi-level linkage pull-down menu based on an MVC (Model View Controller, Model View Controller) model. Background technique [0002] In software system development, it is often necessary to set a Web main page for a specific application software. If the application software has many functions, a multi-level drop-down menu may be required to include all of its functions. For example, the main menu in the game software system has a main menu of "props", and the props menu can be subdivided into items, such as figure 1 and figure 2 The first-level menu shown is "props general category, item classification", the second-level menu of item classification is "physical props, attribute props, functional props, and combat props, etc.", and the third-level menu of physical props is "role". [0003] At present, the existing multi-level linka...

Problems solved by technology

Its advantage is fast response, but using pure javascript will have the following disadvantages: it can only realize the static linkage of multi-level drop-down menus, and its content is fixed, which is only suitable for relatively fixed selection, such as selecting a province, and the corresponding city changes also There are few multi-level linkage drop-down menus, and it is impossible to realize the secondary options that need to be changed dynamically

Due to this, it is difficult to expand and maintain

[0005] To sum up, it can be seen that the existing technical solutions for implementing multi-level linkage drop-down menus obviously have inconvenience and defects in actual use, so it is necessary to improve them
