OnUnLoad

[Simon Wigzell]

I'm using OnUnLoad in my body statement to redirect to a function to clean
things up if someone exits a form by closing it from outside the webpage
code - e.g. by not using the cancel or save and exit buttons I have supplied
but by clicking on the browser window top right X or closing it by clicking
with the right mouse button on the tray icon for the window. Unfortunately
it is also triggered by a refresh, which my web page does as part of it's
functionality. Is there not a way of only trapping "improper" exiting of a
web page? Thanks.

Depends on why and when you refresh. Whether or not it is predictable enough
to set a variable onbeforerefresh and don't set it otherwise. Then make the
unload function check that variable before doing its thing.

On load:
....
if (Explorer) {self.attachEvent('onunload',sayByeBye);}
else if (Netscape) {self.addEventListener('onunload',sayByeBye,true);}
else {/* just forget it */}
....

Then supposing you know when you want to refresh your site (and you should
for sure!):

Before refresh:
if (Explorer) {self.detachEvent('onunload',sayByeBye);}
else if (Netscape) {self.removeEventListener('onunload',sayByeBye,true);}
else {/* just forget it again*/}
Now do your refresh...
