How can I implement AJAX form validation in ASP.NET MVC?

You can implement AJAX form validation in ASP.NET MVC by using jQuery to send asynchronous requests to your controller.

What are the steps to set up jQuery for this?

First, include the jQuery library in your project. Then, create a JavaScript function to handle the form submission and validation.

Can you show me a code example?

Sure! Here's a simple example:

$('#myForm').submit(function(e) {
    e.preventDefault();
    $.ajax({
        type: 'POST',
        url: '/Controller/Action',
        data: $(this).serialize(),
        success: function(response) {
            // Handle success
        },
        error: function(xhr) {
            // Handle error
        }
    });
});

What about server-side validation?

Server-side validation is crucial for security. You can use data annotations in your model to validate inputs before processing them.
