JAVASCRIPT - New window without URL (location)

Hi friends,

I write because I have integrated into the storyline following trigger:

var address = "http://www.google.com";

var target = "_blank";

win = window.open (address, target, 'width = 640, height = 360');

It works correctly, opening a popup of 640 x 360 with Google page.

Now what I need is to hide the URL (location), I implemented "location = 0 (or no)."

var address = "http://www.google.com";

var target = "_blank";

win = window.open (address, target, 'location = 0, width = 640, height = 360');

But I can't hide the url.

Anybody could help me?
