Abstract

The present invention discloses a filtering method based on a tree structure, which comprises: according to a page access request, acquiring tree original data; executing an data filtering operation on the tree original data in a manner of defining a plurality of categories to obtain tree data with an extended attribute; and displaying the tree data with the extended attribute into the tree structure by a user page control. The present invention also discloses a filtering apparatus based on the tree structure.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a filtering method and device based on a tree structure. Background technique [0002] In the field of computer technology, the tree-shaped data structure is a common structure in software development. Many systems have tree-shaped menus and pull-down linkages. The filtering methods for tree-shaped data are also different. A highly available and filterable tree The shape method can effectively improve the software development efficiency and save the development cost. Usually, developers are developing a tree menu on the left, for example, there are three levels, the first level is the first level classification, the second level is the second level classification, and the third level is the third level classification, and at the same time in the page It is necessary to filter data according to different rules, for example, to see different nodes of the tree according to differ...
