Create one pop-under per day?

I try search how create a pop-under but I didn’t find any code can make one pop-under per day. Please give me a suggestion with javascript and jQuery!
Thanks!

You want to have a pop-up display once every 24 hours to visitors of your site.
E.g. On Monday visitors would see Monday’s pop-up, on Tuesday it would be Tuesday’s pop-up etc.

Is this correct?

No, it not.
I want to have a pop-under display once every 24 hours to visitors of your site and only once pop-under url. On monday ,tuesday … see same pop-under.
Pop-under not pop-up please!

Hi,

I still not quite sure what you’re asking, but here’s a great tutorial on how to create user friendly pop-under ads: http://icant.co.uk/articles/how-to-create-popunders/

As to deciding how to display this, maybe you could set a cookie which expires after 24hrs and serve the ad based on its presence/absence?
