Problems solved by technology

At present, most of the preservation technologies of mind maps need to save the attributes (position, name, etc.) of each node and the relationship between nodes. The disadvantage of such preservation is that the stored files are relatively large and the analysis algorithm is relatively complicated.

Embodiment 1

[0084] Please refer to figure 1 as well as figure 2 , Embodiment 1 of the present invention is:

[0085] A method for saving and loading a mind map, including a saving step and a loading step;

[0086] The saving steps include:

[0087] S11. Obtain the names of all nodes and the parent-child relationship between all connected nodes;

[0088] S12, save the name of the node as a file in JSON format according to the parent-child relationship between the nodes; specifically: S121, save the node name in the hash table according to the parent-child relationship between the nodes; S122, save the name of the node in the hash table The name of the first node with the parent node is saved as a JSON object; S123, with the first node as the parent node, according to the parent-child relationship between nodes, at least one second node as the child node of the first node is obtained, and the second node is The name of the node is saved as a JSON object according to the parent-child re...

Embodiment 2

[0095] Please refer to image 3 , the second embodiment of the present invention is:

[0096] A mind map saving and loading system, comprising:

[0097] Obtaining module 1, which is used to obtain the names of all nodes and the parent-child relationship between all connected nodes;

[0098] Preservation module 2 is used to save the name of the node as a file in JSON format according to the parent-child relationship between nodes; The relationship is saved in the hash table; the second saving module 22 is used to save the first node name that does not have a parent node in the hash table into a JSON object; the third saving module 23 is used to use the first node as a parent node , obtain at least one second node as a child node of the first node according to the parent-child relationship between the nodes, and save the second node name into a JSON object according to the parent-child relationship between the nodes; the conversion module 24 is used to judge whether there is a...

Abstract

The invention provides a storage and loading method of mind mapping and a storage and loading system thereof. The storage and loading method comprises the following steps: acquiring parent-child relation between names of all nodes and all connecting nodes; storing the names of the nodes as a file with the JSON format according to the parent-child relation among the nodes; the loading comprises the following steps: analyzing the file with the JSON format to obtain all the nodes and establishing a two-dimensional coordinate system on a display screen; acquiring a first node without a parent node, and positioning the first node in the coordinate system; adopting the first node as the parent node, and obtaining at least one second node used as a child node of the first node according to the parent-child relation among the nodes; calculating and positioning a coordinate of the second node used as the child node according to the coordinate of the first node used as the parent node and preset horizontal distance and vertical distance between the parent node and the child node; and judging whether un-positioned nodes exist, if so, using the second node as the first node and executing the former two steps, and if not, ending positioning.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for saving and loading a mind map, and a system for saving and loading. Background technique [0002] At present, mind maps are widely used in education. Using mind maps, teachers can see students' thinking logic and thinking process in real time, and grasp the students' state in an all-round way. At present, most of the preservation technologies of mind maps need to save the attributes (position, name, etc.) of each node and the relationship between nodes. The disadvantage of such preservation is that the stored files are relatively large and the analysis algorithm is relatively complicated. [0003] JSON is a lightweight data exchange format that is easy for humans to read and write, but also easy for machines to parse and generate (network transmission speed); its unique tree structure can effectively reflect the relationship between various elements. [0004] If t...
