コンパクトな複数選択でjQueryアプリを強化

チェックされたコンボボックスドロップダウンコントロールを活用して、インターフェースを乱雑にすることなく、省スペースで直感的な複数選択を実現

A checked combobox is a data editor component used in user interfaces that consists of a text box with a drop-down panel. This panel displays a predefined list of items, in a clean and organized layout, from which users can input data by making a singular or multiple selections using the adjacent checkboxes. The values are then typically displayed as a comma-separated summary in the collapsed field. This type of control provides developers with a convenient way to implement multi-select functionality within their applications, and is especially effective in scenarios such as filtering datasets or configuring settings, without consuming additional space on the interface.

Several jQuery data editor collections include checked comboboxes, including:

  • DevExtreme Complete Data Editors (part of DevExtreme Complete by DevExpress) enables developers to easily integrate checked comboboxes into their jQuery applications.
  • Kendo UI for jQuery Data Editors (part of Kendo UI by Telerik) allows the integration of multi-item selection within a drop-down using checkboxes for intuitive data input.
  • jQWidgets Data Editors (part of jQWidgets) provides jQuery components that can be used to deliver multi-selection via a combobox input field with adjoining checkboxes.
  • Infragistics Ignite UI for jQuery Data Editors (part of Infragistics Professional) facilitates straight-forward data entry using a multi-select combobox with checkbox support.

PDFを正確に暗号化/復号化

8月 5, 2025
堅牢な暗号化を使用してPDFファイルを保護し、必要に応じて簡単に復号化して、許可されたユーザーのアクセスを復元

Encrypting and decrypting PDF files is a key feature in many modern PDF components, allowing developers to protect sensitive information and control access to documents. Encryption applies a security layer to the PDF, typically requiring a password to open or modify the file, while decryption reverses the process for authorized users. These capabilities are essential for applications that handle confidential business data, legal documents, or personal records, ensuring compliance with security policies and data protection regulations.

Several JavaScript PDF controls offer the ability to encrypt or decrypt PDF files including:

  • Wijmo PDF (part of Wijmo by MESCIUS) enables developers to apply password-based encryption when generating PDFs, ensuring that only authorized users can view or alter the document.
  • Aspose.PDF for JavaScript via C++ provides robust encryption options, including support for various encryption algorithms and permission settings to restrict printing, copying, and editing, along with decryption capabilities for authorized access.
  • IronPDF for Node.js by Iron Software offers high-level methods to encrypt and decrypt PDFs, supporting both user and owner passwords, making it straightforward to secure documents before distribution and to unlock them when required.

ツリーリストは、階層データを拡張可能な形式で表示し、並べ替え、フィルタリング、編集が組み込まれているため、表示と管理を簡素化

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.

四角形の注釈を使用すると、ユーザーはPDFにマークアップできるため、レビュー、承認、共同編集がより効果的かつ視覚的に明確化

Rectangle annotations in PDF viewer components enable users to highlight, mark, or comment on specific areas within a PDF document by drawing rectangular shapes. This feature is commonly used for reviewing documents, collaborating on content, or emphasizing sections in technical or legal workflows. It enhances user interactivity within the viewer, allowing for visual references and context-specific notes without altering the original document content.

Several React PDF viewer controls offer rectangle annotations including:

  • Document Solutions for PDF by MESCIUS provides rectangle annotations as part of its comprehensive annotation API, supporting precise placement and customization.

Vue.jsアプリケーションでデータグリッドをJSONにエクスポート

7月 24, 2025
表形式データを解析が容易で、他のシステムと統合可能な形式のJavaScript Object Notation (JSON)でエクスポート

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.
