Technique that enhances the manipulation of an HTML tree presentation by using an array representation of the hierarchical path of a tree node

摘要

The present invention discloses a method for manipulating the presentation of an AJAX tree using an array representing the hierarchical path of a tree node. Such a method can begin with the receipt of a user-request to expand a selected tree node of an AJAX tree in a Web page. Next, it can be determined if the tree node is present in the existing path array. When the tree node is present in the existing path array, the existing path array can be modified for the selected tree node. A new path array can be requested from the AJAX engine when the tree node does not exist in the existing path array. A path array handler can be invoked to expand the AJAX tree using the existing path array.
