Making a window pop under in chrome

Question

I have a button that needs to open a new window as a popup (under the parent page). In IE/Firefox, it works fine, but in chrome the popup appears over (on top of) the parent

Answer 1

The end of popunder is here. Chrome closed it yesterday.

Answer 2

window.open('http://google.com','','height=500,width=500');
window.open().close();

Don't use popunders for evil
