Confirm Close of Window

[kpikul]

I am trying to come up with a function that will confirm the user actually wants to close the browser window.

It is easy to do if I create the close button but I am trying to have it work if someone closes the window another in other ways. For example the X button. Here is were I am with it. The confirm works but if they click Cancel the window closes anyway. Can anyone steer me in the right direction?

function init() {
    if (confirm("You have not submitted your registration yet.  Are you sure you want to quit?")) {
      parent.close();
    }
    else
    {
    alert("Close cancelled.");
    }
}
window.onunload = init;

You can not close, using javascript methods, a window which was not previously opened on using javascript methods. Is it your case?

I have a registration site where users are closing their browser using the X button (top right of IE) on the review page. I want to alert them if they do this that they are registration has not been submitted until they click continue to the confirmation.

Basically I want to fire off a confirm when the user closes their browser which i can successfully do with the above function. The problem is, if they click cancel on this confirm alert it closes the brower anyway.

You need window.onbeforeunload.

window.onbeforeunload = function () {
return "If you leave now, your registration will be canceled.";
};
