用新的 DataCharts 附加组件简化图表创建

12月 19, 2024
SpreadJS v18 引入了一个新的可选附加组件，用于将图表绑定到外部数据，从而实现动态和灵活的电子表格可视化。

SpreadJS by MESCIUS is a high-performance JavaScript spreadsheet component designed to seamlessly integrate Excel-like functionality into web applications. It empowers developers to deliver robust spreadsheet experiences within their applications, complete with features like data import/export, complex formulas, conditional formatting, and extensive customization options. To extend its capabilities, SpreadJS offers a variety of optional add-ons, such as tools for reporting, charting, and data management. SpreadJS caters to a wide range of use cases, from financial modeling and data analysis to project management and interactive dashboards, ultimately allowing developers to build feature-rich and user-friendly web applications.

SpreadJS v18 introduces the DataCharts Add-On, a powerful new feature that lets you bind charts directly to external data managed by the Data Manager, eliminating the need to embed data within the workbook. This innovation streamlines workflows by reducing redundancy, simplifying updates, and enabling dynamic charting for both standalone spreadsheets and reports. For users of the ReportSheets Add-On, the DataCharts Add-On is seamlessly integrated, enhancing report creation with interactive, data-driven visuals. Developers seeking a flexible solution for external data visualization in other contexts can license the DataCharts Add-On separately, making it ideal for projects that demand adaptable, visually engaging charts.

For more information see our release notes.

SpreadJS is licensed per developer and includes 1 Year Maintenance (major and minor version releases and unlimited support phone calls). SpreadJS requires an Annual or Perpetual Deployment License. The optional Add-ons are available at an additional cost, and require a SpreadJS license. See our SpreadJS licensing page for full details.

从 JavaScript 应用程序将文档打印为 PDF

让您的应用程序用户通过虚拟打印机将文件输出为静态 PDF，从而以共享格式保留内容，以备分发。

Printing to PDF allows users to save an existing document, webpage, or file as a PDF by using a virtual printer. It captures the document exactly as it would appear if printed, preserving the formatting, layout, and styling. The resulting document is typically static and cannot be edited, ideal for archiving or sharing finalized versions of a document. This feature is particularly useful for standardizing outputs across different software, ensuring consistent presentation, and providing an easy way to generate PDFs from files that do not natively support the format. By integrating PDF viewers with this functionality, developers can streamline the creation of high-quality, portable documents directly from a wide range of applications.

Several JavaScript PDF viewers allow users to print to PDF, including:

  • Document Solutions for PDF by MESCIUS includes a full-featured JavaScript-based PDF viewer and editor that allows you print documents to PDF for easy distribution.
  • Kendo UI PDF for Angular (part of Kendo UI by Telerik) enables seamless print-to-PDF functionality for Angular applications to save files as static, print-ready PDFs.
  • PrizmDoc Viewer by Accusoft equips JavaScript applications with the ability to print files to PDF for an effective means of saving, preserving and sharing high-quality files.

设计优先考虑包容性和可用性的界面，从而确保在任何设备上通过无缝导航提供一致的用户体验。

A responsive layout is a design approach that enables web and application interfaces to automatically adjust and optimize their structure, content, and elements for different screen sizes and devices. By using flexible grids, scalable images, and adaptable components, responsive layouts ensure a consistent and user-friendly experience across desktops, tablets, and mobile devices. For software developers, this approach simplifies the creation of cross-platform applications, improves accessibility, and enhances user satisfaction by delivering interfaces that perform seamlessly in diverse environments.

Several Angular grid components support responsive layouts including:

  • IntegralUI Grid (part of IntegralUI Web by Lidor Systems) lets you create customizable data grids with responsive layouts, ensuring seamless performance across devices.
  • Handsontable by Handsoncode facilitates intuitive data management through responsive, Excel-like grids that adapt dynamically to varying screen sizes for maximum usability.
  • Kendo UI for Angular Grid (part of Kendo UI by Telerik) empowers developers to build grids with powerful data handling and consistency across devices and resolutions.
  • DevExtreme HTML5 JavaScript Data Grid (part of DevExtreme Complete by DevExpress) enables responsive data presentations, combining adaptive layouts with advanced editing.
