How can I implement client-side validation in my MVC app?

You can use JavaScript or jQuery to validate form inputs before they are submitted to the server. Would you like a code example?

Yes, please provide a code example for validating an email field.

Sure! Here's a simple example:

function validateEmail(email) {
    const re = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/;
    return re.test(String(email).toLowerCase());
}

You can call this function on form submission to check if the email is valid.

What if I want to show error messages on the form?

You can display error messages by manipulating the DOM. For example, if the email is invalid, you can show a message next to the input field.
