Problem description :JS Handle the addition, deletion, modification and query of tree structure
Recently, I am developing a permission management module of the background management system , Data processing logic involving various tree structures , for example : increase , Delete , Change , Check etc ; Compared with ordinary array structure data , The processing of tree structure is not as intuitive as array , But it's not that complicated , It takes a little more —— Recursive search To perform deep traversal of data , What about here , Bloggers also share with you the methods summarized in the development process , One article will take you through JS Tree structure data processing :
Examples of data structures
Solution :
1、 New node
Find the specified node of the tree structure , Add child node , The code is as follows :
2、 Delete node
Find the specified node of the tree structure , Delete node , The code is as follows
3、 Modify node
Recursively find and modify the state of a node , The code is as follows :
4、 Find node
Recursively find a node of the tree node , Code :
summary
This paper introduces js How to deal with the addition, deletion, modification and query of tree mounted data structure , Master the above functions , It can basically deal with data processing of the same business type , more js Difficulties in dealing with data problems , It is recommended to check the previous articles summarized by bloggers , Friends who like bloggers can pay attention to bloggers , Focus , Neverlost , Bloggers take you on the highway ~~
