Exporte dados de grade como tabelas HTML em aplicativos JavaScript

Janeiro 31, 2025
A funcionalidade de exportação para HTML oferece aos desenvolvedores a capacidade de extrair dados de grade de seus aplicativos JavaScript para integração a projetos da Web.

Exporting grid data to HTML is a valuable feature in grid components, enabling developers to generate structured, web-friendly representations of their datasets. This capability allows users to capture the current state of a grid, including applied filters, sorting, and formatting, and convert it into a HTML document for sharing, archiving, or further processing. By preserving the layout and styling, exporting to HTML ensures that the visual integrity of the grid is maintained, making it a convenient alternative to exporting data in static formats like CSV or Excel. The ability to export grids as HTML tables allows you to easily integrate the resultant file with web applications, and makes grid applications more useful. This provides flexibility that makes them ideal for a variety of use cases, including reporting, data dashboards, and embedding structured data within web pages.

Several JavaScript grid components allow you to export to HTML, including:

  • Sencha Ext JS Grid (part of Sencha Ext JS) offers a comprehensive export-to-HTML feature, allowing users to generate clean and structured HTML tables directly from the grid.
  • jQWidgets Grid (part of jQWidgets) provides built-in export functionality that supports HTML, enabling seamless conversion of grid content into a shareable web format.

Atualize dados dinamicamente em relatórios JavaScript

Janeiro 30, 2025
A conectividade de dados robusta permite que os componentes de relatórios gerenciem grandes conjuntos de dados, apliquem transformações e forneçam insights precisos e interativos.

Data connectivity options allow reporting components to integrate with various data sources to retrieve, process, and display data in reports. It typically involves connecting to databases, APIs, web services, or in-memory data structures to fetch real-time or static data. This connectivity is often achieved through frameworks, libraries, or built-in support for data binding and querying mechanisms, such as RESTful APIs, GraphQL, or direct database connections via server-side proxies. Reliable data connectivity enables reporting components to efficiently manage large datasets, perform transformations, and dynamically refresh reports, delivering interactive and precise insights to end-users.

JavaScript reporting components support various data connections including:

  • ODBC (Open Database Connectivity): Standardized API for accessing relational databases that enables JavaScript (via server-side languages or tools) to connect to databases like MySQL, SQL Server, and Oracle.
  • OLEDB (Object Linking and Embedding, Database): Microsoft API for accessing various data sources, including relational and non-relational databases. Typically used in Windows environments for high-performance data access.
  • XML (Extensible Markup Language): Markup language for structured data representation and transport. Frequently used for configuration, data exchange, and reporting in JavaScript applications.
  • JSON (JavaScript Object Notation): Lightweight data interchange format that is native to JavaScript. Widely used for web APIs, dynamic data exchange, and JavaScript-based reporting tools.
