Dieses Projekt ist ein jQuery-Plugin und clientseitiger Formular-Validator, der verwendet wird, um Webformular-Eingaben zu verifizieren, bevor sie an einen Server gesendet werden. Es verwendet eine regelbasierte Validierungs-Engine, um Benutzereingaben gegen vordefinierte oder benutzerdefinierte Regeln zu prüfen, um die Datenintegrität im Browser sicherzustellen. Das Tool ist als ARIA-konformes Validierungssystem konzipiert und verwendet Accessibility-Attribute, um Fehlermeldungen mit Eingabefeldern zu verknüpfen. Dies stellt sicher, dass Screenreader-Benutzer benachrichtigt werden, wenn ein Feld während des Formularübermittlungsprozesses einen ungültigen Wert enthält. Das System unterstützt Remote-Server-Validierung via asynchroner HTTP-Anfragen und erlaubt die dynamische Regel-Injektion, um benutzerdefinierte Validierungslogik hinzuzufügen. Es verwaltet das User-Interface durch DOM-verknüpftes Fehler-Rendering und nutzt ereignisgesteuertes Triggern, um Prüfungen während Focus-, Blur- oder Submit-Events auszuführen.
Provides a library for defining and enforcing validation rules on web form inputs.
This project is a jQuery-based form validation library designed to verify HTML form input values on the client side before submission. It functions as an input validator that enforces data integrity constraints through rule-based verification and value normalization. The library focuses on web accessibility compliance by linking error messages to input fields via ARIA attributes, ensuring that screen readers can announce validation failures to the user. The system supports the creation of custom validation rules and the transformation of raw input strings through a normalization pipeline. Co
A jQuery-based library for verifying HTML form input values against predefined or custom rules.
This project is a digital signature collector and public petition platform designed as a labor rights advocacy tool. It functions as a web application for gathering names and professional affiliations to create public lists of support. The platform focuses on labor rights advocacy and employee collective action, specifically organizing signatures to protest illegal working hours and labor abuses. It facilitates professional solidarity campaigns by gathering endorsements from industry experts and employees to bring visibility to labor disputes. The system manages the collection of signatures
Uses schema-based validation to ensure submitted professional and employee signatures follow required data formats.
Parsley.js is a JavaScript form validation library that provides a client-side data validator for verifying input correctness before submission. It functions as an HTML attribute-based validator, allowing constraints to be defined declaratively within HTML data attributes to enforce rules without requiring custom scripts. The framework distinguishes itself through a customizable validation system that supports user-defined rules and custom error message templates. It includes a remote validation interface to verify form values against server endpoints via asynchronous network requests and sup
A JavaScript library for validating HTML form inputs using data attributes to enforce rules without writing custom scripts.
Valibot is a modular, type-safe schema library for validating and parsing structural data in TypeScript environments.

Dieses Projekt ist eine reaktive State-Management-Bibliothek für den Umgang mit komplexen Formulardaten und Validierungslogik. Sie nutzt beobachterbasierte Muster, um UI-Komponenten mit zugrunde liegenden Datenmodellen zu synchronisieren und sicherzustellen, dass Formularzustände während der gesamten Anwendung konsistent bleiben. Die Bibliothek bietet einen strukturierten Ansatz zur Verwaltung von Formularinitialisierung, Feldverfolgung und Lebenszyklusereignissen. Die Bibliothek zeichnet sich durch ihre Unterstützung für tief verschachtelte Datenstrukturen und hierarchische Komposition aus, was rekursive Validierung und dynamische Updates innerhalb komplexer Objektbäume ermöglicht. Sie verfügt über eine schema-gesteuerte Validierungs-Engine, die sowohl synchrone als auch asynchrone Regeln unterstützt, neben einer Middleware-artigen Abfangfunktion, die es ermöglicht, Daten während Feld-Updates zu überwachen oder zu transformieren. Entwickler können spezifische Felder dynamisch über pfadbasierte Adressierung aufrufen und manipulieren, was Flexibilität bei der Arbeit mit großen oder sich entwickelnden Formularmodellen bietet. Über das Kern-State-Management hinaus enthält die Bibliothek Dienstprogramme für Datentransformation, wie das Formatieren von Eingabewerten und das Berechnen von Feldwerten basierend auf anderen Formulardaten. Sie bietet Multi-Formular-Orchestrierungsfunktionen zur Koordination von Validierung und Übermittlung über mehrere Instanzen hinweg und bleibt von spezifischen Präsentationsschichten entkoppelt, um die Integration mit jeder UI-Komponentenbibliothek zu ermöglichen. Das Framework bietet zudem integrierte Tools zur Überwachung von Feld-Lebenszyklusereignissen und zum Debuggen interner Zustandsübergänge.
