Introduction

Client side form validation in ASP.NET Core stinks.

Specifically, tag helpers and HTMLHelper methods generate non-standard validation attributes and require the use of the jquery.validate and jquery.validate.unobtrusive libraries.

This library overrides this behavior to generate standard HTML5 validation attributes.

FAQ

  • Why not just use the jquery.validate and jquery.validate.unobtrusive libraries?

    These libraries are not standard HTML5 validation attributes and require additional JavaScript libraries to work. This library generates standard HTML5 validation attributes that work out of the box with modern browsers.

  • Does it have any imapct on server side validation?

    No, this library only affects client-side validation.

  • Does this library work with Blazor?

    No, this library only works with ASP.NET Core MVC Razor Pages and MVC apps that use tag helpers and HTMLHelper form input methods.
