window.onbeforeunload

[tecknick]

Hi All

I am using the window.onbefore unload event on a webpage as follows :

window.onbeforeunload = confirmExit;

function confirmExit()
  {
    if (changesMade == 1 && needToConfirm)
        {
        return "You have not saved changes on this page";
        }
  }

The function returns a prompt to the user correctly.

If the user clicks "OK" on the dialog, the page exits correctly. However I would like to know if the user clicks "Cancel" .

The reason behind this is that I have a animated gif which appears on the unloading of a window and if the user clicks "Cancel" which stops the unload I would like to hide the animated gif.

Does anyone know how to determine if the "Cancel" button on the onbeforeunload dialog has been selected?

Thank you in advance.

There's no proper method of determining if Cancel has been clicked.

You can try using a timeout and cancelling onunload, but it may not work reliably.
