Hidden div window

I have input for username and password on the login page, and after submitting username and password are sent to node.js via POST request, and node.js will check they are valid. If they are node will send a response that they are valid. And after that response, I want to show the div window on the same page. That div is for inputting code from the email. What is the best way to open that input window?
