how to check if a popup is close?

Use the window.closed property:

Code:

if (!win || win.closed) {
// window closed...
}

no matter the popup is open or closed...the alert still never run..
why?

thanks a lot.

Code:

 
win =window.open("fillsn.htm", "name", "width=600,height=600");
 
if (!win || win.closed) {
alert("closed");
}

Again, there's not enough time for it to register. Use a button:

Code:

<input type="button" value="Is it closed?" onclick="isClosed();">
