In my case, I just needed to close my pop-up and redirect the user to his profile page when he clicks "ok" after reading some message I tried with a few hacks, including setTimeout + self.close(), but with IE, this was closing the whole tab...
Solution :
I replaced my link with a simple submit button.
<button type="submit" onclick="window.location.href='profile.html';">buttonText</button>.
Nothing more.
This may sound stupid, but I didn't think to such a simple solution, since my pop-up did not have any form.
I hope it will help some front-end noobs like me !
