用树列表视图显示分层数据

7月 25, 2025
树列表以可扩展的格式展示分层数据，用内置的排序、筛选和编辑功能来简化显示和管理。

TreeLists in UI suites are specialized components designed to display hierarchical, self-referencing data in a tabular format with expandable and collapsible rows. They combine the structure of a tree view with the functionality of a data grid, offering built-in features such as sorting, filtering, editing, and paging. This makes them ideal for scenarios where complex relationships must be presented clearly, such as organization charts, project task structures, file directories, or product categories. Their intuitive layout and powerful data management capabilities help streamline workflows and enhance the user experience in enterprise and business applications.

Several jQuery UI suites feature a treelist control including:

  • jQWidgets lets you organize hierarchical data in a grid with built-in sorting, filtering, and editing for seamless interaction and control.
  • Infragistics Professional enables you to display structured, self-referencing data in expandable rows with full support for editing, paging, and responsive layouts.
  • Kendo UI by Telerik allows you to present hierarchical tabular data with intuitive expand/collapse features, rich interactivity, and flexible data management tools.
  • DevExtreme Complete by DevExpress facilitates interactive display of tree-structured data using advanced grid features like inline editing, filtering, and virtual scrolling.

在 Vue.js 应用程序中将数据网格导出为 JSON

7月 24, 2025
以 JavaScript Object Notation（JSON）导出表格数据，这种格式易于解析并与其它系统集成。

Exporting a data grid to JSON format is a common feature in modern web-based data tools that involves converting the structured data displayed in a grid, such as rows and columns representing records and fields, into JavaScript Object Notation (JSON), a lightweight, text-based format commonly used for data interchange. This process enables the grid's contents to be saved in a machine-readable structure that preserves the hierarchy and attributes of the data, making it easily consumable by web services, APIs, or other applications. The benefits of exporting to JSON include its compatibility with a wide range of programming environments, ease of integration with frontend and backend systems, and suitability for transmitting data across networked systems or persisting it for later use in client-side operations or remote storage.

Several Vue.js grid controls allow you to export to JSON, including:

  • FusionGrid by FusionCharts works with Vue.js and allows you to export grid data to JSON, enabling seamless integration with APIs and JavaScript-based applications.
  • jQWidgets Grid (part of jQWidgets) offers a straightforward method to convert visible grid data to JSON in Vue.js apps, preserving data types and custom formatting.
  • Jspreadsheet Pro Data Grid (part of Jspreadsheet Pro) enables Vue.js applications to export spreadsheet-style data to JSON, ideal for syncing with databases or external services.
  • DataGridXL facilitates JSON output from grid data, ensuring compatibility with modern frameworks and smooth data handling in JavaScript-driven workflows.
