Method for realizing presentation of tree-structure data in World Wide Web page as well as system and device therefor

Abstract

The invention discloses a method for realizing presentation of tree-structure data in World Wide Web page as well as a system and a device therefor. The method comprises the following steps: after starting a WEB system, a server accesses a database server frequently to create and / or update a required XML data file for a tree structure, so as to load and / or refresh dynamic data in the tree structure. The invention leads a user to click the upper and lower levels of the tree structure freely for data presentation without sending a request to the server at the moment, thereby greatly increasing the response speed and the exhibition efficiency of the page and further greatly improving the user experience.

Description

technical field [0001] The present invention relates to a tree structure display technology of a World Wide Web (WEB, World Wide Web), in particular to a method, system and device for realizing data display of a tree structure of a WEB page based on an extensible markup language (XML, XML-eXtensible Marked Language). Background technique [0002] With the rapid development of the Internet, WEB sites have gradually become an indispensable companion in people's daily work and life. With the gradual promotion of the WEB2.0 standard, in the browser / server (B / S, Browser / Server) application system The demand for displaying directories and data in a tree structure is also becoming stronger. As we all know, the tree structure refers to the data structure with a "one-to-many" tree relationship between data elements, and has been widely used in many fields, such as the management structure of files in the file system, family tree, etc. . [0003] XML is a simple data storage languag...

Problems solved by technology

[0012] First, it does not distinguish between dynamic data and static data. If the data source is not from the database (DB, Data Bank) but from the xml maintained by the artificial background, this method cannot solve the problem, and the control of the style is limited to HTML. Not conducive to expansion and maintenance

[0013] Second, AJAX technology is used in its implementation, and asynchronous calls are used to improve the user's tree structure display effect experience. The data is obtained by accessing the database when the tree structure is clicked, but because the source of the data is completely dependent on the specific Database, the response of the database directly affects the response effect of the display page, and at the same time increases the burden on the database server, increases the complexity of the system, increases the difficulty of system development, and reduces the reliability of the system
