[Javascript] Closing a pop-up containing a frameset when focus is lost

Tue Sep 4 12:01:56 CDT 2001

This is my best shot and is working OK in Win98 MSIE5.5 and NN4.7

Any improvments welcome.

// This is in the top frameset:

var aeWin=null;

//  opens the popup
function aepop(){
aeWin = window.open('addedit.htm','ae','<SNIP>');
}

// closes the popup
function closeWin(winHandle) {
if (winHandle && !winHandle.closed )
          {winHandle.close();}
}

function closeWin called from the main window main-frame files with this
handler in their <BODY> tags.

onfocus="top.closeWin(top.aeWin)"

Any thoughts?

TIA
