FAQ Topic - How do I open a new window with javascript?
-----------------------------------------------------------------------

New windows can be opened on browsers that support the
` window.open ` function and are not subject to the action of any
pop-up blocking mechanism with code such as:-

var wRef;
if(window.open){
wRef = window.open("http://example.com/page.html","windowName");
}

That appears, when read carefully, to be possibly true.

But if the code

var wRef;
if (window.open) {
wRef = window.open("http://www.merlyn.demon.co.uk/gullible.htm","X") }

is pasted into the textarea at the bottom of
<http://www.merlyn.demon.co.uk/gravity0.htm> and the adjacent button is
pressed, then a new window, showing gullible, appears in my Firefox
3.0.15.

My Firefox 3.0.15, if caused to look at all of the external links which
from time to time appear in <http://www.spacetoday.net/>, sometimes
plausibly claims to have blocked a pop-up (pop-unders are not 100%
blocked ;-( ).

Therefore, what appears to be and will normally be taken as a necessary
condition, "not subject to the action of any ...", is apparently not a
necessary condition, and the FAQ section needs to be corrected.
