Problems solved by technology

Tables combined with pagination are the most commonly used display in WEB applications. However, program developers need to consider many factors such as color, typesetting, and row and column layout in the interface display of data tables, which consumes too much time and labor. Results cannot be reused, resulting in waste of resources

specific Embodiment approach

[0033] The specific implementation method comprises the following steps:

[0034] Use JSP's Tag tag technology to encapsulate data pagination and the processing process of template interface analysis:

[0035] 1) Introduce the JSP data automatic pagination JSTL tag in the web.xml file in the web project. After the introduction is successful, the front-end JSP page can use this tag technology;

[0036] 2) The front-end JSP page introduces the core file of JSP data automatic paging JSTL tag technology "core file content includes

[0037] Core JavaScript template processing classes and stylesheets”;

[0038] 3) The front-end JSP introduces the template definition, which defines the header of the data table and display information items;

[0039] 4) The front-end JSP introduces template parsing engine and data rendering engine files;

[0040] 5) Call the JSP data automatic pagination JSTL tag, and assign values ​​to the data page number of the tag, the number of data items per ...

Abstract

The invention relates to the java server page (JSP) data automatic paging java standard tag library (JSTL) label technology and application. Extensive markup language (XML) label is defined as: writing XML files according to the JSTL standard format, and writing corresponding JAVA processing classes. Template analysis engine includes: writing a JavaScript template analysis engine for specially analyzing template definition. A data rendering engine is used for analyzing data and emerging the data into a paging form. The Tag labeling technology of JSP is used in packaging of data paging and in a template interface analyzing processing process, wherein core files of the JSTL label of the paging are guided in by a front stage JSP page. Template definition is guided in by a front stage JSP. Developers write a data obtaining method, and data obtained from a database are required to be packaged into a javascript object nation (JSON) data aggregate format. The JSTL paging label analyzes the template definition to automatically generate a paging form. The JSTL label automatically transmits asynchronous javascript and XML (AJAX) requests to a WEB server and displays the returned data to the JSP page.

Description

technical field [0001] The invention relates to a data automatic paging technology of Java Web application software, in particular to a JSP data automatic paging JSTL tag technology. Background technique [0002] With the continuous development of network technology, network-based WEB applications are becoming more and more extensive. Tables combined with pagination are the most commonly used display in WEB applications. However, program developers need to consider many factors such as color, typesetting, and row and column layout in the interface display of data tables, which consumes too much time and labor. The results cannot be reused, resulting in a waste of resources. Contents of the invention [0003] Technical problem to be solved: In view of the above problems, the present invention provides a JSTL tag technology for automatic paging of JSP data. This technology can reduce the writing time of front-end JSP display codes, and free developers from the cumbersome in...
