Stimulsoft Reports.JS 使用基於運算式的檔路徑或 URL 實現靈活的、資料驅動的報表結構。

Stimulsoft Reports.JS provides a robust reporting toolkit designed specifically for JavaScript applications. This library leverages a client-side architecture, offering a pure JavaScript report engine for efficient report rendering directly within web browsers. The solution includes a user-friendly report designer for building reports with various data sources and visualizations, along with a report viewer for seamless integration and display within your JavaScript applications. This eliminates the need for server-side dependencies or browser plugins, simplifying the development process for embedding powerful reporting functionalities into your web projects.

The Stimulsoft Reports.JS includes expressions within the URL and File fields of the Sub-Report component. This functionality helps developers to dynamically determine the source of a sub-report, whether it is a file path or a web address, based on the evaluation of expressions. Consequently, this allows for the creation of more adaptable and context-aware reports where the embedded sub-report content or linked resources are determined programmatically based on the main report's data, offering greater flexibility in report design and data integration without the need for static configurations.

Stimulsoft Reports.JS is licensed per developer and is available as a Perpetual license with 1 year support and maintenance. See our Stimulsoft Reports.JS licensing page for full details.

Stimulsoft Reports.JS is available individually or as part of Stimulsoft Ultimate.

在資料網格應用中將列設置為必填

使用 JavaScript 中的網格控制項定義必填列，從而確保填寫基本欄位以保持輸入完整有效。

A fundamental feature in a data grid is the ability to specify that a column must be populated with values and cannot be left empty. By designating certain columns as mandatory, developers can enforce input rules that prevent users from leaving critical fields blank, such as user identifiers, product names, or timestamps. Required columns are typically enforced through validation rules that prevent the submission or processing of incomplete records, thereby ensuring the completeness and validity of data entries. This improves data integrity, reduces the likelihood of processing errors, and supports consistent business logic across applications that rely on structured datasets.

Several JavaScript grid controls allow you to set columns as required, including:

  • Wijmo FlexGrid (part of Wijmo by MESCIUS) is a JavaScript data grid that allows columns to be marked as required, including built-in validation logic to ensure compliance.
  • Jspreadsheet Pro Data Grid (part of Jspreadsheet Pro) supports the use of validation rules to ensure entries meet predefined criteria, enabling you to define mandatory fields.
  • SmartClient Grid (part of SmartClient by Isomorphic Software) equips JavaScript apps with required column configuration to prevent the submission of incomplete records.
  • Ignite UI Angular Grid (part of Infragistics Ignite UI) offers developers an out of the box validator to enforce the population of required columns during data entry.
