Hi,

I have an HTML form which enters data in an Access database using ASP. But
now my client asked me if it is possible to alert users, when they click a
link other then submit on the page, that there is unsaved data and if they
want to save. If so the page must redirect to the ASP page that writes the
data and then go to the page that they click and if not the page should be
redirected to the link they clicked.

I tried using the onUnload and onBeforeUnload events, but gives me no result

I hope someone can help

Marco,

When the onUnload event is triggered it is already too late, the page is 
already in the process of being unloaded. About the only thin I can 
think of would to have all of your links call a confirming function, pop 
up a confirm box and then, based on their answer, either stay there or 
follow the link. Even then there is the back button, their favorites 
list and just plain old closing the browser. Your never going to be able 
to cover all of the possiblilites, no matter what type of application it 
is and a web app is even harder. Just make it as robust as possible and, 
most likely, after they've done it once, they wont leave it again with 
out saving  :)

The onBeforeUnloadEvent is MS specific I think only for their JScript.

Hope that helps a little
