Validation on the client side for a form that is displayed within a bootstrap modal using ajax technology

Within my ASP.Net Core application, I am faced with the need to utilize validation on both the server side and client side in a bootstrap modal form. While I have successfully implemented server side validation, I have encountered difficulties when it comes to implementing client side JavaScript validation.

Despite following and attempting everything outlined in various resources, such as:

  • Manually registering the form with unobtrusive validation
  • Ensuring my modal form is included in the DOM
  • Implementing Unobtrusive Client Side Validation in ASP.NET Core

I have also verified that the necessary JavaScript files are included in the correct sequence:

<script src="js/jquery.min.js"></script>
<script src="js/jquery.validate.min.js"></script>
<script src="js/jquery.validate.unobtrusive.min.js"></script>
<script src="js/jquery.unobtrusive-ajax.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="js/site.js"></script>

In order to assist further, I have shared a sample project on Github-Repository, where the server side validation functions correctly without any issues.

What steps should I take to ensure successful implementation of client side validation?

Answer №1

After testing your code on GitHub, it was clear that the source of your script was incorrect. I made some modifications:

<script src="~/js/jquery.min.js"></script>
......

The script is now functioning correctly locally:
