[Proto-Scripty] Re: Ajax.Request unload
Thanks for responding, and checking the code.
i guess i should have noted: i'm also using FirePHP, so there are
lines in place sending debug log lines back to Firebug. However, on
only this particular call, absolutely nothing gets sent back from the
server. Not even a log line saying the PHP script was executed.
No SOP violation (Internal.fileList.Path is correct), i've adjusted
all Internal references to be prefixed by window, though you are
correct, there are no other Internal objects in that context.
In a bizarre twist, if i create a new button in my application and
observe click to the EXACT same block of code, it executes
flawlessly.

Hi Joe,
The client-side code looks okay to this second pair of eyes. (You
might want to put window. in front of Internal in the Ajax.Request
constructor, just for consistency as you've done it everywhere else.
But I'm assuming you don't have some other Internal defined in
scope, and so it should be using the same one anyway.)
I'd suggest the usual things: Check that
window.Internal.fileList.Path really has the correct path and that
it's not violating SOP; temporarily try replacing that path with a
static file path to eliminate issues in the server-side processing;
put debugging checks on the server-side resource it's calling; the
usual sort of stuff. I suspect an issue with the server-side
resource.
But the client-side part looks okay, FWIW.

i have the following:
Event.observe(window,'unload',function(){
if (window.Internal window.Internal.doUnload){
(new Ajax.Request(Internal.fileList.Path,{
asynchronous:false,
method:get,
parameters:{do:unload,task:$_GET.p},
onSuccess:function(t){alert('Success: ' + t.responseText);}
}));
alert('Wait!');
}
});
The Wait alert at the end is just for testing. It does fire.
The problem is, the Ajax call does not seem to work at all. Firebug
tells me the Ajax block is executed, the onSuccess alert even fires.
But t.responseText is always empty, and the actions i've defined in my
server-side code are not happening.
Any takers to try helping me track this down?

[Proto-Scripty] Re: Ajax.Request unload
i presume the page hasn't already unloaded, because the document is
still visible, Firebug can still break at my designated markers, the
alert('Wait!') line still executes AFTER the Ajax call, and only
after i clear the alert does the page actually clear. Being that i'm
setting {asynchronous:false}, i believe that alert won't execute until
the Ajax is complete.
If i place this particular block in beforeunload, i have no way to
tell the PHP if the user has elected to continue unloading or has
canceled the unload. The PHP in this case cleans up files the user has
uploaded while on this page. Since i can't utilize the beforeunload
confirm's return value, the user's files would get cleaned up even if
they cancel the unload.

What happens if you change this event to beforeunload?

[Proto-Scripty] Re: Ajax.Request unload
DAMMIT!
i found the bugger. It was a similar piece of PHP in a different file
that gets called when the page LOADS!
Everything was getting cleaned up before the piece i'm examining could
ever happen.
By the way, Firebug WAS reporting the FirePHP logs. It just happens
that it was displaying them when the next page loaded. Kinda weird,
easy to miss.
Anyway, thanks to both of you for your help.
