Hey guys..
Given
<body id="body">
<a href="somewhereelse.html">Go Somewhere else</a>
</body>
Can I
Event.observe($(''body''),''unload'',function(e)
{ alert(''on unload'');
Event.stop(e); });
To trap the unload on the page?
I''m specifically checking for the ''dirty status'' of a
form.. and I confess I
haven''t played around a lot with this but in my simple tests, the
Unload
wasn''t firing...

Prototype used to use the following line: Event.observe(window, ''unload'', Event.unloadCache, false); Perhaps you need to have "window" be your observer, and not "body".

"body" doesn''t trigger unload.
To invoke onunload
Close the current browser window.
Navigate to another location by entering a new address or selecting a Favorite.
Click the Back, Forward, Refresh, or Home button.
Click on an anchor that refers the browser to another Web page.
Invoke the anchor click method.
Invoke the document write method.
Invoke the document open method.
Invoke the document close method.
Invoke the window close method.
Invoke the window open method, providing the possible value _self for
the window name.
Invoke the window navigate or NavigateAndFind method.
Invoke the location replace method.
Invoke the location reload method.
Specify a new value for the location href property.
Submit a FORM to the address specified in the ACTION attribute via the
INPUT_submit control, or invoke the form submit method.
Default action Removes the object or document from the browser window.
So, try ...
Event.observe(window, ''unload'', function(e) { Event.stop(e);
alert(''onunload''); });
But all that will do is alert you. You cannot stop the browser from closing.

Thanks Richard I''ll bet thats what I was missing.. I figured since the ''onload'' event was on the body tag, that the ''unload'' event would also be there. Your post was very helpful, thanks again Gareth On 8/30/07, Richard Quadling <rquadling-gM/Ye1E23mwN+BqQ9rBEUg@public.gmane.org> wrote:> > > "body" doesn''t trigger unload. > > To invoke onunload > Close the current browser window. > Navigate to another location by entering a new address or selecting a > Favorite. > Click the Back, Forward, Refresh, or Home button. > Click on an anchor that refers the browser to another Web page. > Invoke the anchor click method. > Invoke the document write method. > Invoke the document open method. > Invoke the document close method. > Invoke the window close method. > Invoke the window open method, providing the possible value _self for > the window name. > Invoke the window navigate or NavigateAndFind method. > Invoke the location replace method. > Invoke the location reload method. > Specify a new value for the location href property. > Submit a FORM to the address specified in the ACTION attribute via the > INPUT_submit control, or invoke the form submit method. > > Default action Removes the object or document from the browser window. > > So, try ... > > Event.observe(window, ''unload'', function(e) { Event.stop(e); > alert(''onunload''); }); > > But all that will do is alert you.
