Node Attribute Mapping for Simpler HTML5 Drag-and-Drop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The implementation of drag-and-drop functions in HTML5 applications requires complex coding, leading to low development efficiency.
Innovation Solution
A data processing method that obtains and associates attribute data with nodes on a target interface, allowing direct modification of these attributes based on drag-and-drop operations, simplifying the process and reducing the need for extensive code writing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional HTML5 drag-and-drop implementation is used, then the function can be achieved, but a large number of complex codes need to be written resulting in low development efficiency
Solution Approach 1:
The patent introduces an intermediary mechanism by associating attribute data with DOM nodes through a mapping relationship. Instead of directly manipulating complex DOM objects and their attributes through lengthy JavaScript code, the system uses an intermediate layer that connects interface elements to their underlying attribute data, simplifying the drag-and-drop implementation
Solution Approach 2:
The patent creates a simplified representation or copy of the node's attribute data that can be directly manipulated. By working with this copied/associated attribute data structure rather than the full DOM object, the complexity of drag-and-drop operations is reduced while maintaining the ability to modify node properties
2Ease of operation
If attribute data is directly associated with nodes, then drag-and-drop operations can be simplified, but additional data management overhead is introduced
Solution Approach 1:
The patent merges the attribute data with the node representation by creating an association between them. This combining allows the system to treat attribute data and node information as an integrated unit, simplifying operations while the underlying structure manages the data relationships
3Speed
If location data is modified based on drag-and-drop operations, then node positioning is updated in real-time, but data consistency management becomes more complex
Solution Approach 1:
The patent implements a feedback mechanism where drag-and-drop operations trigger automatic updates to the associated attribute data, specifically the location data. The system continuously monitors operation data from drag events and feeds this information back to update the node's position, ensuring real-time synchronization while maintaining data consistency through the established association structure

AI summary
The present disclosure relates to a data processing method and apparatus, a device and a medium. In the present disclosure, by obtaining the attribute data of the operation object corresponding to the node displayed on the target node in the program code and associating the obtained attribute data with the corresponding node, the attribute data associated with the node can be modified directly based on the operation data corresponding to the drag-and-drop operation when dragging and dropping the node on the target node, without the need to search for the operation object, such that through a simple operation process, dragging and dropping the node can be displayed, enabling the node to be displayed at the position where the drag-and-drop operation ends based on the modified attribute data.
