JavaScript PDFビューアを使用して、PDFフォームでフィールドを直接追加、名前変更、または削除。外部エディターの必要なし

In JavaScript-based PDF viewers, the ability to add, edit, remove, and rename form fields within Acrobat-style PDF forms allows developers and users to dynamically manage form structure and content directly within the browser. This functionality enables real-time customization of interactive PDF documents without requiring external PDF editors. By supporting operations like inserting new text fields, adjusting existing ones, deleting unused fields, or updating field names to match data schemas, this feature significantly enhances the flexibility and usability of PDF forms. It benefits workflows such as document automation, digital signatures, and data collection, particularly in applications where user-driven or programmatic form manipulation is essential for tailoring documents to specific tasks or data sources.

Several JavaScript PDF viewer components allow you to add, edit and remove form fields from PDF forms, including:

  • Document Solutions for PDF by MESCIUS includes a JavaScript PDF viewer in the Professional edition that enables developers to modify and manage form fields.
  • PrizmDoc Viewer (part of PrizmDoc by Accusoft) provides an HTML5 document viewer which lets you adjust, rename, and delete PDF form fields within a JavaScript interface.
  • Syncfusion PDF Viewer (part of Syncfusion Essential Studio Enterprise) equips JavaScript applications with PDF form functionality, including interactive form field manipulation.

かぎ足チャートを使用したJavaScriptチャートコントロールは、ノイズをカットし、ブレイクアウトを強調表示し、市場ダイナミクスの需要と供給の傾向を明確化

Kagi charts are a technical analysis tool that display price movement through vertical lines, ignoring time to focus on significant price changes. Thick lines indicate rising demand when prices break above previous highs, while thin lines signal increased supply when prices fall below previous lows. This clear visual format helps traders filter out noise, identify trends, and spot key breakouts or reversals. Ideal for analyzing market sentiment, Kagi charts are used across stocks, forex, and commodities to support confident, data-driven trading decisions.

Several JavaScript chart components provide Kagi charts, including:

  • Wijmo FlexChart (part of Wijmo by MESCIUS) allows you to interpret price dynamics using Kagi charts, filtering noise to reveal clearer trading signals and sentiment.
  • FusionCharts Suite XT enables Kagi chart rendering to highlight price breakouts and reversals, enhancing clarity in trend-based market visualizations.
  • LightningChart JS Trader lets you visualize supply and demand shifts with Kagi charts for high-performance, real-time financial data analysis.

SmartClient 14.1は、サーバーロジックやパフォーマンスに影響を及ぼすことなく、親ノードを表示したままにすることで、JavaScriptアプリの大規模なデータセットフィルタリングを改善

SmartClient is a powerful JavaScript component suite compatible with React, Vue, Angular, and more, designed for building large-scale, high-performance web apps. It offers advanced UI components, dynamic data handling, customizable grids, and responsive design. Ideal for enterprise use cases like financial analytics and real-time reporting, SmartClient supports seamless backend integration and delivers optimized performance and scalability.

SmartClient has enhanced hierarchical data handling with the included KeepParentsOnFilter setting, ensuring that parent nodes remain visible in filtered views, even when data is loaded dynamically. It loads "skeleton branches" via a complex client-driven algorithm, automatically managed by SmartClient, to maintain high performance without preloading the entire tree, meaning it doesn't require server-side programming. This is particularly useful in large datasets with load-on-demand trees, as it allows users to maintain full visibility into the structure of filtered results without losing context. By preserving the hierarchical path to matching records, this feature improves usability and clarity in tree-based components, especially in applications where understanding the parent-child relationship is critical.

SmartClient is licensed per developer and is available as both perpetual and subscription licenses. Product updates and technical support is also available. See our SmartClient licensing page for full details.

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.
