Embodiment Construction

[0054] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention .

[0055] The core idea of ​​the present invention is: on the server side, search keywords according to the tree nodes input by the user, perform fuzzy matching among all loaded tree nodes from top to bottom, and use a recursive algorithm to determine that the matched tree nodes are in the tree structure After the hierarchical path in ; on the client side, the Flex tree control uses this path to locate the tree node.

[0056] Such as figure 1 As shown, a tree node query method of an asynchronous tree provided by an embodiment of the present invention includes the following steps:

[0057] S10. Initialize the Flex tree control as an asynchronous tree; ...

Abstract

The invention discloses a method and a system for inquiring a tree node of an asynchronous tree. The method comprises the steps of: initializing a Flex tree control as an asynchronous tree; obtaining input target tree node inquiry information by a server, and accordingly performing fuzzy matching on all the tree nodes to obtain path information from the target tree nodes to root nodes and returning the path information to a client; analyzing the obtained path information by the Flex tree control at the client, locating the path information to the target tree nodes by utilizing a recursive algorithm and displaying. In comparison with the prior art, the method and the system for inquiring the tree node of the asynchronous tree provided by the invention well solve the inquiry problem of the tree nodes under the asynchronous loading condition on the basis of unchanging the original inquiry function of the Flex tree, can position the tree nodes from upside to downside according to the tree structure, and is greatly improved in the aspect of usability.

Description

technical field [0001] The present invention relates to the technical field of dynamic environment monitoring, and in particular to a tree node query method and system of an asynchronous tree. When loading in the same way, the tree node query of the asynchronous tree is realized. Background technique [0002] In the dynamic environment monitoring system, in order to better reflect the hierarchical relationship between upper-level nodes and lower-level nodes, such as the hierarchical relationship between regions and stations, tree structures are usually used to display this hierarchical relationship. [0003] Generally speaking, the number of bottom stations in the dynamic environment monitoring system is often relatively large, and the loading method of tree nodes is usually loaded in an asynchronous manner. Usually, the loading method of the asynchronous tree is: first, only the first layer of tree nodes is loaded by default, and other nodes (such as the child nodes of the...
