Javascript pop under window (Background window)

Question

I'm to open pop-up windows BEHIND the current active screen using java script. Here is my simple code.

var win = window.open('http://yahoo.com',null,"height=400,width=600,status=yes,toolbar=no,scrollbars=yes,menubar=yes,location=yes");
win.blur();
this.window.focus();

But it doesn't seems to be work in any browser. It simply opens a pop up.I referred this question from stackoverflow. But it doesn't work. My aim is to create a background window in all browsers. Someone help me please

makePopunder("http://www.yourdomain.com/");

You cannot do this. Modern web browsers do not allow websites to steal the focus from other tabs (because this could become quite messy for the users). The only thing that you could do is prompt your users to open in a new tab (which does not change the focus). Or you can abuse an alert to get the focus back to your page:

var win =   window.open('http://yahoo.com',null,"target=_blank,height=400,width=600,status=yes,toolbar=no,scrollbars=yes,menubar=yes,location=yes");
alert("Welcome back");
