JavaScript / HTML5 新闻
确保所有用户的可访问性和数据清晰度
6月 2, 2025
遵守 WCAG 标准，并通过直观的 JavaScript 图表提供清晰、可访问的信息。
WCAG (Web Content Accessibility Guidelines) compliance in JavaScript charts ensures that visual data representations are accessible to all users, including those with disabilities. This involves implementing features such as semantic markup for assistive technologies, keyboard navigation support, high-contrast color schemes for users with visual impairments, and descriptive alternative text for charts and data points. Additionally, it may include providing data tables or summaries as textual alternatives and ensuring that interactive elements are operable without reliance on a mouse. Achieving WCAG 2.0 compliance enhances usability, meets legal accessibility standards, and promotes inclusive user experiences across web applications.
Several JavaScript chart controls offer WCAG compliance including:
- Highcharts by Highsoft includes an accessibility module with keyboard navigation, screen reader compatibility, high-contrast themes, and support for voice input and sonification.
- DevExtreme Chart (part of DevExtreme Complete by DevExpress) provides features like keyboard navigation, screen reader support, and high-contrast themes.
- Kendo UI for Angular Chart (part of Kendo UI by Telerik) incorporates features such as keyboard navigation, semantic HTML output, and screen reader compatibility.
- amCharts: Charts library includes keyboard navigation, high-contrast display modes, and text-based data alternatives to enhance accessibility.

从电子表格数据生成 PDF
5月 30, 2025
使用户能够在保留内容和样式的同时，直接在 JavaScript Web 应用程序中将电子表格导出为 PDF 文件。
Exporting a spreadsheet to PDF from a JavaScript application is a widely used feature that allows users to generate portable, print-ready documents directly from the browser. It converts the contents of a spreadsheet, such as cell data, formulas, formatting, charts, and images into a Portable Document Format (PDF) file. This capability ensures that the data, formatting, and layout from the original spreadsheet are preserved without relying on external applications or manual intervention. It is particularly useful for generating reports, invoices, or records that need to be shared, printed, or archived in a fixed format. By enabling PDF generation directly within the web application, developers can offer users a straightforward method to archive, print, or share spreadsheet content in a consistent and professional format across devices and platforms.
Several JavaScript spreadsheet components allow you to export to PDF, including:
- SpreadJS by MESCIUS enables users to convert complex spreadsheet content, including formulas and styling, directly to PDF within a JavaScript application.
- Telerik Spreadsheet jQuery (part of Kendo UI) provides an integrated PDF export option that retains the structure and styling of the spreadsheet for uniform document output.
- Jspreadsheet Pro, through the export to PDF extension, facilitates the export of spreadsheet content to PDF, ensuring the integrity of the original document.
- Syncfusion Spreadsheet JavaScript (part of Syncfusion Essential Studio Enterprise) allows you to save spreadsheet documents as PDF files, preserving layout and style.
