Agosto 8, 2025
Use visualizadores de PDF JavaScript para adicionar, renomear ou remover campos diretamente em formulários PDF, sem a necessidade de editores externos.

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.

Preserve o contexto da árvore em exibições filtradas

Agosto 8, 2025
O SmartClient 14.1 melhora a filtragem de grandes conjuntos de dados em aplicativos JavaScript, mantendo os nós pai visíveis, sem impacto na lógica do servidor ou seu desempenho.

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.

Corrija e valide documentos estruturados

Agosto 6, 2025
Ferramentas de documentos estruturados com recursos de validação e verificação ajudam a identificar e resolver problemas em arquivos XML e JSON durante a edição.

Validation and checking features in structured document tools are designed to ensure the integrity, correctness, and compliance of documents written in formats like XML and JSON. These tools assist developers and content authors throughout the editing process, detecting syntax errors, enforcing structural rules, and maintaining standards conformance. By integrating automated validation, intelligent correction suggestions, and format-specific diagnostics, these features reduce manual debugging effort and enhance the reliability of structured content in technical and data-driven applications.

Common features include:

  • XML validation verifies that an XML document adheres to a specified schema, ensuring correct data types, required elements, and attribute structures are present.
  • XML-aware spell checkers identify spelling mistakes only within text nodes of XML documents, avoiding false positives in tags, attributes, or code fragments.
  • XML-well formedness checkers confirm that an XML document is syntactically correct, with properly nested and closed tags, valid characters, and a single root element.
  • DTD validation checks XML documents against a Document Type Definition (DTD), ensuring that the document structure matches the defined grammar.
  • XML quick fixes offer automated suggestions to resolve common XML errors, such as missing required elements or incorrectly structured tags.
  • JSON validators allow the comparison and validation of JSON objects against JSON schema, looking for unbalanced brackets for example, to ensure compliance with formatting rules.
