javascript - Close popup window

Question

I have a popup window which is opened using this code:

function _openpageview(fieldid,objectid,opennew)
{
var url='/s_viewpagefield.jsp?fieldid='+fieldid+'&codedid='+objectid;

  web_window = window.open(url,'_blank', 'menubar=yes,location=no,scrollbars=yes,width=800,height=600,status=no,resizable=yes,top=0,left=0,dependent=yes,alwaysRaised=yes');
   web_window.opener = window;
   web_window.focus();


}

How can I close that popup from within the popup?

window.close();
self.close();
web_window.close();

all did not work

An old tip...

var daddy = window.self;
daddy.opener = window.self;
daddy.close();
