Show thank you page in a popup window?

Hello.

I am trying to show thank you text in a popup in order to not redirect the user.

My site is a single page so i do not have any other pages except index.html. 

I am using this 
https://www.jotform.com/answers/177481-Pop-up-Thank-you-and-redirect-to-complete-submissions

for reference, but the problem is that I cannot disable redirection.

Is there a way to show your Thank you text (which is in the conditional thank you page), without redirecting the user, or disable the redirection?

Thank you in advance!

If you do not wish your users to be redirected on another page, then you could just use JotForm's custom "Thank You" message instead.

To learn more about this, you can check this guide: https://www.jotform.com/help/211-Setting-Up-the-Thank-You-Page 

If you want to change the "Thank You" message based on your users' inputs, then you can use conditional logic for this, here's a specific guide for it: https://www.jotform.com/help/372-How-to-Change-Thank-You-Message-Using-Conditional-Logic 

Now regarding the pop-up message, it is NOT possible to setup a pop-up window for the "Thank You" page without setting up a separate web page, you might also need to use the form's full source code and have a custom script that will do the auto pop-up of the thank you message.

I hope that helps.
