Validating data in a form loaded via AJAX?

Question

Yii

When you click on a block on the site with Ajax, an html input form is loaded from the server, in which the user types something, for example:
<input type="text" id="edit-field" value="">
I also know what data should be in this form and would like to check them for validity.
What are the options in this case? Is it possible to use validation from yii?
