Description

Technical Field

[0001] This invention relates to the field of front-end development technology, specifically a dynamic visual layout system and implementation method based on React and SVG. Background Technology

[0002] In scenarios such as data visualization and front-end interface design, users' demand for dynamic interaction is increasing, and static layout methods are no longer sufficient. Existing layout solutions are mostly based on fixed grids or preset templates, lacking flexibility and real-time visual editing capabilities, and are difficult to adapt to personalized layout needs.

[0003] Traditional HTML+CSS layout methods have obvious limitations: on the one hand, element positioning operations are cumbersome, especially when dealing with complex graphic arrangements, they are inefficient; on the other hand, they are not powerful enough in vector graphics rendering, and cannot efficiently support the dynamic display and interaction of high-precision graphics.

[0004] In contrast, React, as a high-efficiency front-end component framework, has powerful component state management and efficient update mechanisms, enabling flexible control and dynamic response of interface elements; SVG (Scalable Vector Graphics) has advantages such as supporting complex graphics rendering, native support for dynamic interaction, lightweight file size and cross-device display adaptation, and performs outstandingly in visualization scenarios.

[0005] However, a complete system has not yet been formed for the application of React and SVG in dynamic layout. How to give full play to the advantages of both to solve the defects of traditional layout and meet the needs of dynamic interaction and personalized layout has become an urgent technical problem to be solved. Summary of the Invention

[0006] This invention addresses the needs and shortcomings of current technological development by providing a dynamic visual layout system and implementation method based on React and SVG. It enables visual dragging, scaling, layout adjustment, and real-time preview of page elements, improving front-end layout efficiency and user experience. It also supports flexible storage and reuse of layout schemes, meeting the dynamic layout needs of diverse business scenarios.

[0007] In a first aspect, the present invention provides a dynamic visual layout system based on React and SVG, and the technical solution adopted to solve the above-mentioned technical problems is as follows:

[0008] A dynamic visual layout system based on React and SVG, comprising:

[0009] The layout container and state initialization module is used to create the root component layout container LayoutContainer, which renders the layout canvas based on SVG and has a built-in grid background with 50px intervals to assist alignment. At the same time, it initializes the layout data layoutData, which includes an empty element array elements, a group hierarchy tree groups, and the initial state of the currently selected element selectedElement, providing the basis for the operation of subsequent modules.

[0010] The component-based vector element encapsulation module is used to encapsulate layout elements into reusable SVG components based on the React component architecture. It supports dynamically passing styles and data through props to achieve lightweight rendering.

[0011] The interactive layout operation module is used to enable element dragging and grid snapping by listening to the mousedown / touchstart events of SVG, supporting pixel-level precise positioning and automatic alignment; it also supports double-clicking elements to activate the editing mode, controlling the scaling and rotation of elements via the scroll wheel or handle, and supports multi-selection of elements to create groups, enabling the overall movement, scaling, and infinite nesting hierarchical management of elements within the group.

[0012] The responsive layout adaptation module is used to leverage the vector characteristics of SVG, enabling the LayoutContainer to scale proportionally by setting the viewBox property, automatically adapting to different screen sizes and ensuring consistent display on mobile and PC.

[0013] The layout state management module is used to implement global layout state management using React Context, synchronize element position, style and hierarchy data in real time, and support shortcut key undo / redo operations, and retain up to 50 steps of history.

[0014] The layout scheme storage and reuse module is used to serialize layout data (layoutData) into JSON format and save and load layout schemes through local storage or API interface.

[0015] Optionally, the componentized vector element encapsulation module involved specifically includes the following operations:

[0016] Users select an element type via the toolbar, triggering the addElement method to insert a new element object into layoutData.elements, which includes default styles and position coordinates;

[0017] By using React's useEffect hook to listen for changes in layout data (layoutData), the SVG rendering function (renderElements) is called to dynamically generate elements based on the element data. <g>Grouping tags enables batch rendering of elements.

[0018] Optionally, the specific interactive implementation of the interactive layout operation module is as follows:

[0019] Drag events: Bind an onDragStart event to each element to record the initial coordinates and mouse offset; update the element coordinates in the onDrag event and trigger requestAnimationFrame to optimize rendering performance; trigger onDragEnd when the drag ends to execute the grid snapping and alignment logic.

[0020] Scaling and Rotation Events: After entering edit mode, add scaling and rotation handles to the element, and update the element's width, height, and transform properties by dragging the mouse wheel or handles;

[0021] Right-click menu: Bind the onContextMenu event to pop up a right-click menu that supports "copy", "delete", "pin to top" and "create group" operations, and implement independent management of menu hierarchy through React Portal.

[0022] Optionally, the specific adaptation logic of the responsive layout adaptation module involved is as follows:

[0023] Listen for the window resize event, calculate the scaling ratio of the layout container (LayoutContainer), update the viewBox property of the SVG to 00${containerWidth}${containerHeight}, and adjust the grid spacing and handle size to ensure interaction accuracy.

[0024] Optionally, the specific implementation of the layout scheme storage and reuse module is as follows:

[0025] Provides the saveLayout method to convert layout data layoutData into JSON format and then store it encrypted on the local machine or server.

[0026] It provides the loadLayout method to parse JSON data, reconstruct the element and grouping states, thereby enabling the rapid reuse of layout schemes.

[0027] Secondly, this invention provides a method for implementing dynamic visual layout based on React and SVG. The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0028] A method for implementing dynamic visual layout based on React and SVG includes the following steps:

[0029] S1. Create the root component layout container LayoutContainer, which renders the layout canvas based on SVG and has a built-in grid background with 50px intervals to assist alignment; at the same time, initialize the layout data layoutData, which includes an empty element array elements, a group hierarchy tree groups, and the initial state of the currently selected element selectedElement, providing the basis for the subsequent process.

[0030] S2. Based on the React component architecture, layout elements are encapsulated into reusable SVG components, which support dynamic passing of styles and data through props to achieve lightweight rendering;

[0031] S3. Elements can be dragged and snapped to the grid by listening to the mousedown / touchstart events of SVG, supporting pixel-level precise positioning and automatic alignment; double-clicking an element activates the editing mode, and the element can be scaled and rotated by scroll wheel or handle. It supports multi-selection of elements to create groups, and realizes the overall movement, scaling and infinite nesting of elements within the group.

[0032] S4. Based on the vector characteristics of SVG, the LayoutContainer can achieve proportional scaling by setting the viewBox property, automatically adapting to different screen sizes and ensuring consistent display on mobile and PC.

[0033] S5. Utilize React Context to achieve global layout state management, synchronize element position, style, layer and other data in real time, support shortcut key undo / redo operations, and retain up to 50 steps of history;

[0034] S6. Serialize the layout data layoutData into JSON format, and save and load the layout scheme through local storage or API interface.

[0035] Optionally, the implementation of step S2 may specifically include the following operations:

[0036] Users select an element type via the toolbar, triggering the addElement method to insert a new element object into layoutData.elements, which includes default styles and position coordinates;

[0037] By using React's useEffect hook to listen for changes in layout data (layoutData), the SVG rendering function (renderElements) is called to dynamically generate elements based on the element data. <g>Grouping tags enables batch rendering of elements.

[0038] Optionally, step S3 specifically includes:

[0039] Drag events: Bind an onDragStart event to each element to record the initial coordinates and mouse offset; update the element coordinates in the onDrag event and trigger requestAnimationFrame to optimize rendering performance; trigger onDragEnd when the drag ends to execute the grid snapping and alignment logic.

[0040] Scaling and Rotation Events: After entering edit mode, add scaling and rotation handles to the element, and update the element's width, height, and transform properties by dragging the mouse wheel or handles;

[0041] Right-click menu: Bind the onContextMenu event to pop up a right-click menu that supports "copy", "delete", "pin to top" and "create group" operations, and implement independent management of menu hierarchy through React Portal.

[0042] Optionally, step S4 specifically includes:

[0043] Listen for the window resize event, calculate the scaling ratio of the layout container (LayoutContainer), update the viewBox property of the SVG to 00${containerWidth}${containerHeight}, and adjust the grid spacing and handle size to ensure interaction accuracy.

[0044] Optionally, step S6 specifically includes:

[0045] Provides the saveLayout method to convert layout data layoutData into JSON format and then store it encrypted on the local machine or server.

[0046] It provides the loadLayout method to parse JSON data, reconstruct the element and grouping states, thereby enabling the rapid reuse of layout schemes.

[0047] The present invention provides a dynamic visual layout system and implementation method based on React and SVG, which has the following advantages compared with the prior art:

[0048] 1. This invention achieves dynamic layout and real-time preview of page elements through interactive methods such as dragging, scaling, and snapping alignment; it utilizes React's component-based architecture and SVG's vector graphics characteristics to support responsive layout, multi-level grouping, style customization, and layout scheme storage and reuse, and is suitable for scenarios such as data visualization, low-code platforms, and dashboard design, with the advantages of lightweight, high scalability, and cross-device adaptation.

[0049] 2. This invention replaces the traditional code writing mode with visual drag-and-drop, zoom and other operations, which greatly reduces the technical threshold of layout development. Front-end engineers can quickly complete complex interface designs such as multi-level nesting and responsive adaptation without writing complex positioning code, saving more than 50% of layout development time. It is especially suitable for low-code platforms and rapid prototyping scenarios.

[0050] 3. This invention achieves anti-aliasing effect on graphic edges based on SVG vector graphics rendering technology, ensuring that elements remain clear and sharp at any scaling ratio; drag and zoom operations achieve stable frame rate through requestAnimationFrame, combined with configurable grid snapping and automatic alignment algorithms, improving layout accuracy to the pixel level. Users can quickly master the operation logic without professional training, reducing the learning cost by 30%.

[0051] 4. This invention relies on the vector characteristics of SVG and the event system encapsulation of React. The same layout scheme can natively support mouse interaction on PC and touch operation on mobile devices. The container scaling ratio can be dynamically adjusted through the viewBox property, and the layout elements can automatically adapt to multiple terminal devices such as mobile phones, tablets, and desktop monitors without the need for additional adaptation code development.

[0052] 5. This invention adopts an open component-based architecture design, which supports the integration of third-party visualization libraries (such as ECharts, AntV, D3.js, etc.) through a custom component mechanism. Developers can quickly extend complex element types such as charts, maps, and forms based on the SVG component specification to meet the diverse business scenario needs such as data visualization analysis, BI dashboard design, and industrial monitoring interfaces.

It supports dynamically passing styles and data through props to achieve lightweight rendering.

[0060] The interactive layout operation module is used to enable element dragging and grid snapping by listening to the mousedown / touchstart events of SVG, supporting pixel-level precise positioning and automatic alignment; it also supports double-clicking elements to activate the editing mode, controlling element scaling (0.1-5 times) and rotation (0-360°) via the scroll wheel or handle, and supports multi-selection of elements to create groups, enabling overall movement, scaling and infinite nesting of elements within the group;

It also supports shortcut keys (Ctrl+Z / Ctrl+Y) to undo / redo operations and can retain up to 50 steps of history.

[0063] The layout scheme storage and reuse module is used to serialize layout data (including element type, coordinates, size, style, grouping relationship, etc.) into JSON format, and save and load layout schemes through local storage (localStorage) or API interface.

[0064] In this embodiment, the componentized vector element encapsulation module specifically includes the following operations:

[0065] Users select element types (such as rectangles, circles, text boxes, chart components, etc.) via the toolbar, triggering the `addElement` method to insert a new element object into `layoutData.elements`. This element object includes default styles (fill color #fff, stroke 1px solid #ccc) and position coordinates. React's `useEffect` hook listens for changes in the layout data `layoutData` and calls the SVG rendering function `renderElements` to dynamically generate elements based on the element data. <g>Grouping tags enables batch rendering of elements.

[0066] In this embodiment, the specific interactive implementation of the interactive layout operation module is as follows:

[0067] Drag events: Bind an onDragStart event to each element to record the initial coordinates and mouse offset; update the element coordinates in the onDrag event and trigger requestAnimationFrame to optimize rendering performance; trigger onDragEnd when the drag ends to execute the grid snapping and alignment logic.

[0069] Right-click menu: Bind the onContextMenu event to pop up a right-click menu that supports operations such as "copy", "delete", "pin to top" and "create group". The menu hierarchy can be managed independently through React Portal.

[0081] By using React's useEffect hook to listen for changes in layout data (layoutData), the SVG rendering function (renderElements) is called to dynamically generate elements based on the element data. <g>Grouping tags enables batch rendering of elements.

[0082] S3. By listening to the mousedown / touchstart events of SVG, element dragging and grid snapping are realized, supporting pixel-level precise positioning and automatic alignment; double-clicking an element activates the editing mode, and the element can be scaled (0.1-5 times) and rotated (0-360°) by scroll wheel or handle. It supports multi-selection of elements to create groups, and realizes the overall movement, scaling and infinite nesting of elements within the group.

[0084] Drag events: Bind an onDragStart event to each element to record the initial coordinates and mouse offset; update the element coordinates in the onDrag event and trigger requestAnimationFrame to optimize rendering performance; trigger onDragEnd when the drag ends to execute the grid snapping and alignment logic.

[0085] Scaling and Rotation Events: After entering edit mode, add scaling handles (circular areas at the four corners) and rotation handles (semicircular area at the top) to the element. Update the element's width, height, and transform properties by dragging the mouse wheel or handles.

[0086] Right-click menu: Bind the onContextMenu event to pop up a right-click menu that supports operations such as "copy", "delete", "pin to top" and "create group". The menu hierarchy can be managed independently through React Portal.
