هذا المشروع عبارة عن مكون إضافي لـ jQuery ومتحقق من صحة النماذج من جانب العميل يُستخدم للتحقق من مدخلات نماذج الويب قبل إرسالها إلى خادم. يستخدم محرك تحقق قائماً على القواعد للتحقق من مدخلات المستخدم مقابل قواعد محددة مسبقاً أو مخصصة لضمان سلامة البيانات في المتصفح. تم تصميم الأداة كنظام تحقق متوافق مع ARIA، باستخدام سمات إمكانية الوصول لربط رسائل الخطأ بحقول الإدخال. يضمن ذلك إخطار مستخدمي قارئ الشاشة عندما يحتوي الحقل على قيمة غير صالحة أثناء عملية إرسال النموذج. يدعم النظام التحقق من الخادم البعيد عبر طلبات HTTP غير المتزامنة ويسمح بحقن القواعد الديناميكية لإضافة منطق تحقق مخصص. ويدير واجهة المستخدم من خلال عرض الخطأ المرتبط بـ DOM ويستخدم التشغيل القائم على الأحداث لتنفيذ الفحوصات أثناء أحداث التركيز، أو فقدان التركيز، أو الإرسال.

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

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

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

Valibot is a modular, type-safe schema library for validating and parsing structural data in TypeScript environments.
