Features

• Client-Side Input Validators - Provides a frontend tool for cleansing whitespace and verifying input correctness before data is submitted to a server.
• Declarative HTML Validation - Implements a declarative system where validation constraints are defined using HTML data attributes.
• Field Validation - Checks individual form fields against defined criteria and returns a boolean validity status.
• Asynchronous Validation - Performs asynchronous server-side verification of field validity using JavaScript promises.
• Custom Validation Rules - Provides a framework for extending validation logic with domain-specific checks through a pluggable registry.
• Asynchronous Validators - Allows the creation of user-defined rules that return promises for asynchronous validation.
• Form Validation - Provides a comprehensive system for verifying that user input meets specified criteria before processing.
• Asynchronous Validation Interfaces - Implements a remote validation interface to check form values against server endpoints using asynchronous network requests.
• Attribute-Driven Validation - Enforces validation rules through HTML data attributes, removing the need for custom JavaScript definitions.
• Declarative Attribute Validation - Functions as an HTML attribute-based validator, allowing constraints to be defined declaratively within data attributes.
• Form Validation - Executes validation using a combination of built-in validators, community extensions, and remote services.
• Form Validation Libraries - A JavaScript library for validating HTML form inputs using data attributes to enforce rules without writing custom scripts.
• Remote Input Validation - Provides a remote validation interface to verify form values against server endpoints via asynchronous network requests.
• Remote Input Verification - Verifies form field values against remote server endpoints in real time using asynchronous requests.
• Input Validation Triggers - Executes data integrity checks immediately upon user interaction events like blur or keyup.
• Validation Grouping - Supports organizing form fields into named sets to validate specific subsets of a form independently.
• Custom Validation Messages - Provides a system for defining how validation error messages are rendered in the interface using custom containers.
• Form Management - Manages validation rules for dynamic forms that change structure or fields during user interaction.
• Form Submission Management - Intercepts the form submission process to prevent sending data if the validation state is invalid.
• Dynamic Form Generation - Adapts validation rules in real-time as form fields are added or removed from the DOM.
• Validation Behavior Configuration - Offers options to override default validation triggers and interface responses to align with specific project requirements.
• Validation Error Renderers - Offers configurable containers and rendering functions to display validation errors in the user interface.
• DOM Mutation Observation - Monitors the DOM for structural changes to automatically apply validation rules to newly added input elements.
• Form Validation - Front-end form validation without writing JS.
• 表单验证(Form Validator)/表单提示 - Listed in the “表单验证(Form Validator)/表单提示” section of the Awesome Frontend awesome list.
