This article mainly introduces "what is the function of the core components of SimpleFramework". In the daily operation, I believe that many people have doubts about the role of the core components of SimpleFramework. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "what is the role of the core components of SimpleFramework?" Next, please follow the editor to study!

Core components:

The purpose of core components is to supplement core functions that are not provided by the Simple framework in the form of components.

The core of the framework implements the filter-based request-response life cycle process, as well as the component architecture. Therefore, the advantages of implementing the basic functions of the Web framework in the form of components are:

Reduces the implementation complexity of the core code of the framework.

Supplement some of the functions that must be implemented by the implementation framework in the form of components

Framework-based component architecture to realize the pluggability of technologies and components supported by different sources

The component-based implementation mode can greatly ensure the stability of the framework kernel, reduce the coupling between the core functions and the framework kernel, and make the framework have better scalability and upgradeability.

The component implementation mode of the core function further ensures the relative independence and substitutability of the core function, thus improving the smoothness and downward compatibility of the core function upgrade.

AJAX component (ajaxRequest)

With AJAX (Asynchronous JavaScript and XML) as its "shape" and component as its "god", AJAX AJAX Request is encapsulated as a component, so that users do not need to care about the specific connotation of AJAX (such as request, XML data, etc.), and reference it like ordinary components. Furthermore, combined with the combined application of other components, it greatly simplifies the development process of AJAX application, reduces the difficulty of AJAX application development, and reduces the technical threshold of AJAX application. So as to shorten the application development cycle and save the development cost.

Secondly, the component-based AJAX citation masks the technical complexity of AJAX, improves the reusability, realizes the civilian application of AJAX, and makes the transition from Web1.0 to Web2.0 AJAX application smoother and smoother. Thirdly, the component characteristics of AJAX request can be used to upgrade or transform the existing conventional non-component AJAX applications, which can greatly reduce the code amount of the original system, further improve the response ability, stability, ease of use and interaction of the original system, and enhance the user experience.

Validation component (validation)

Take "validation" as its "row", take the component as its "god", and encapsulate validation as a component:

Users do not need to care about the specific details of verification, and define validation as components and their properties (such as types, rules, set of action objects, etc.) rather than (client-side or server-side) code, which greatly simplifies the implementation process of Web verification, reduces the difficulty and threshold, and achieves the purpose of shortening the development cycle and saving development costs.

The componentization of verification masks the technical complexity of verification, improves the reusability, and realizes the configuration and generalization of verification.

The verification implementation of existing conventional non-component applications can be upgraded or modified by using the component characteristics of verification, which can greatly reduce the code amount of the original system and further improve the stability, ease of use and availability of the original system.

The componentization of verification can realize the unification of client-side verification and server-side verification of Web applications: based on the unified verification component rule settings, client-side or server-side verification is selected by type, and the function is completed by the corresponding components.

The implementation of component-based verification makes the verification have good scalability.

Submit component (submit)

Take "commit" as its "row", take the component as its "god", and encapsulate the submission (submit) as a component:

Users do not need to care about the specific details of the submission, and define the submission as the component and its properties (the type of submission and the business processing class, etc.), instead of simplifying the implementation process of "submission" of Web applications, reducing the difficulty and threshold, thus achieving the purpose of shortening the development cycle and saving development costs.

The componentization of submission masks the technical complexity of submission and improves the reusability.

By making use of the submitted component characteristics, the commit implementation of the existing conventional non-component applications can be upgraded or modified, which can greatly reduce the code amount of the original system and further improve the stability, ease of use and availability of the original system.

The componentization of submission makes a clear distinction between AJAX and regular submissions, which further highlights the business relevance of submissions.

The component-based submission implementation makes the submission have good scalability and manageability.

Basic components:

The basic components of SimpleFramework are mainly page display components, which form a system and can be matched, covering almost all aspects of WEB application development. Because of its open component architecture, it has the following characteristics:

The basic components have good scalability. Based on the open component architecture and standard component specification, the basic components can be further extended to meet the actual needs of practical Web application development.

The basic components have good model adaptation. The basic component data source is based on interface design and implementation, so it can meet the needs of different presentation forms of the same (data) model, and the same component can meet the presentation needs of data from different sources.

The basic components have good resource integration, replaceability and polymorphism. Based on the component specification of SimpelFramework, basic components can integrate different component resources (such as multi-file upload components, that is, integrated from SWFUpload), and make basic components replaceable, that is, existing component implementations can be replaced with new component resources; at the same time, the same basic component can be implemented in multiple forms based on different components (resources), showing multiple "forms" (such as unified components can be implemented based on Javscript and Flash)

The basic components have good composability. Because the basic component is designed and implemented based on the same component architecture, it has a well-defined component specification, which fully reflects the non-intersection and inheritance of the application domain and component properties of the component, as well as the interface characteristics of the component resource (provider). It makes the basic components have good composability.

The basic components have friendly availability. Since most of the basic components provide a default processing class (Handle Class), the basic components have friendly availability

Business components:

A business component is a component that can independently meet a certain kind of business needs or independently complete a complete application function, which belongs to the category of composite components, in other words, it completes a specific application function based on the combination of several basic components, takes "complete application or specific function" as its "row", takes component as its "god", and presents "specific application or specific function" with component and its properties completely, such as: comment, voting. Or forums, etc. Therefore, its characteristics are as follows:

Business components have complete "application" or "functional" features. Business component is the true embodiment of "component is application, application is component".

Business components have complete component characteristics. Business components can be used in Web applications in the form of components, with complete component characteristics.

Business components are complex. The business component itself is a "composite component" after the integration of the basic component and the actual application or function, so the business component can be "combined" with other components to form a new business component, that is, it is recomposable.

Business components are accumulative. Business is the result of synchronous accumulation of components and business, so with the development and change of business requirements, the synchronous growth of business-related components can be realized, that is, business components can be accumulated.

Business components have the ability to respond on demand. Because business components are essentially composite applications of basic components, business components have the ability to apply on demand with the growth and change of basic component resources, as well as open component architecture and interface-based implementation patterns.

Business components have the characteristics of business scalability and customization. Because the "business" related attributes and rows of business components are provided by the associated business processing class (Handle Class), business components have business scalability and can customize "special" component properties or behavior in specific application areas, that is, they have customization characteristics.

At this point, the study on "what is the role of the core components of SimpleFramework" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
