work around popup blockers

[Leo Muller]

Hi,

I found a nice way of working around popup blockers. A popup would be opened
automatically, but if it isn't then something else on the page would happen,
like displaying a manual link.

function StartGame(){
var newwin = window.open (http://www.com,"GameWindow","")
if(eval(newwin.opener==this)==true)
{
//if the popup did open do this.
}
else
{
//if the window did not open, do this.
}
}

Since we are all internet developers here, I hope that this may be of use to
anyone. Also comments / improvements are always welcome.

some comments:
- If window.open didn't work, then probably newwin is null, so you can't
immediatly check newwin.opener. ("null or not an object")
- why "eval"?
- you don't need to check for "==true"

so your test could be:
if (newwin != null && newwin.opener == this)
(etc)
