Javascript function to trap when a normal window gets closed

[kgomotso]

I need to know if there is a onwindow.close() (or something like that) function that I can use coz I need to perform some function when the user closes the window

no idea if there's an onwindow.close() event to trap it , I doubt it exists. But you can however check the existance of the window and if it doesn't execute the funtion.
function checkPop() {
if (popup && !popup.closed) {

}
else {

}
}
setInterval("checkPop()",1000);

popup being the name you gave to the popup window ofcourse.
