使用 ActiveReportsJS 創建豐富的主詳細報表，其可清晰展示相關和層級資料。

ActiveReportsJS is a powerful, lightweight reporting tool designed to integrate advanced reporting capabilities into any JavaScript application. ActiveReportsJS enables developers to create, view, export, and print richly formatted reports entirely on the client side - with zero server dependencies.

In this blog post, MESCIUS Product Consultant Victor Stahlman demonstrates how to build nested data regions in ActiveReportsJS to create master-detail reports that display related data, such as customers and their orders, within a structured layout. He walks your through configuring datasets, nesting controls like Lists and Tables, and applying filters to correctly link and present hierarchical data relationships in your reports. Key topics include:

  • Growth vs. Static Data Regions
  • Understanding the Master-Detail Concept
  • Choosing the Report Type
  • Building the Report Structure

By implementing nested data regions in ActiveReportsJS, you can transform flat datasets into structured, master-detail reports that are easier to read and analyze.

Read the complete blog to get started building scalable, dynamic JavaScript reports that deliver more meaningful insights to your users.

Optimajet FormEngine 支援即時 IDE 驗證和自動補全，從而幫助您及早發現問題並改進表單開發。

Optimajet FormEngine is a drag-and-drop React form builder that lets teams create, manage, and render complex web forms without writing frontend code. It allows developers and business users to visually design forms, store them as JSON, and render them at runtime. As a React JS library, it easily integrates into existing applications while giving developers full control over form logic, structure, and data flow, making it well suited for complex data collection.

Optimajet FormEngine enables JSON Schema validation for forms, allowing developers to validate form JSON directly within their IDE, identify structural issues, incorrect data types, and unsupported configurations early in the development process, and enforce a consistent, well-defined structure across all forms. By providing real-time feedback, inline error highlighting, and autocomplete suggestions, it improves accuracy and reduces the need for repeated testing cycles, helping developers work more efficiently while minimizing runtime errors and ensuring more reliable form implementations.

Optimajet FormEngine is licensed based on usage type (internal commercial use, public web/SaaS, or OEM embedding), number of domains for the visual editor, and access to additional ready-made components. Licenses are perpetual and include 6 months or 1 year of updates and support. See our Optimajet FormEngine licensing page for full details.

提供結構化、樹狀導覽，讓使用者直接跳到相關區塊，並更有效率地與文件互動。

Bookmark navigation in a PDF Viewer enables developers to expose the hierarchical bookmark structure embedded within a PDF so users can quickly jump to specific sections or pages. It typically presents bookmarks in a tree view synchronized with the document, allowing programmatic control and event handling for selection changes. This capability improves usability in applications that handle large or structured documents by reducing manual scrolling, supporting faster content discovery, and providing a more organized reading experience.

Several WinForms PDF Viewer components support bookmark navigation, including:

Annotation support in a Vue.js chart component refers to the capability to overlay additional contextual elements, such as labels, markers, lines, or regions, directly onto a chart to highlight specific data points, thresholds, or events. This feature enables developers to enrich visualizations with meaningful insights without altering the underlying dataset, making it easier to communicate key information such as trends, anomalies, or business rules within the UI.

Several Vue.js chart components support chart annotations, including:

  • Wijmo Vue Chart (FlexChart) (part of Wijmo by MESCIUS) lets you add configurable chart annotations that highlight data points, thresholds, and ranges.
  • DevExtreme Vue Chart (part of DevExtreme Complete by DevExpress) allows you to incorporate annotation layers into charts, supporting labels, shapes, and guides.
  • Highcharts Core by Highsoft facilitates advanced chart annotations with flexible positioning, rich styling, and event handling.
  • Kendo UI Vue Charts (part of Kendo UI Vue Charts by Telerik) enables annotation features within charts that visually emphasize key data elements.
