Areyah, thanks for your inputs thus far.
At that point, the user is already in the process of navigating
away from the page.
Keep in mind that I'm talking about large file uploads. For the
typically user that takes about 2-6 hours. So they may be in the
process of navigating away, but that process takes a very long time.
I do understand that I can script my way to doing pretty much
anything I please.
I guess I should have been clearer in my previous post.
What I hope is that the new specs are more about enabling Html and
allowing someone to do something in a declarative manner (to the
extent possible) rather than resort to scripting each time they want
to do something.
Well, events aren't "declarative", and you explicitly
asked for progress events ;)
And so my suggestion...
Use case I'm uploading a large file using an iframe. So yes, the
iframe will be submitted, but the rest of the page is intact. I'm
still left without having the ability to know how long the upload is
going to take and how it is progressing. So while the form is
submitting, today we go through quite a bit of hackry to show our
users progress.
Uploading the form data or files using XMLHttpRequest isn't
a hack.
Having the event
Again, event isn't "declarative". It is all about scripting, in which
case you could just use XMLHttpRequest.
and information allows us to provide
a consistent (across browsers) interface which is extremely important
(as you can imagine) and does not require the server side to support
this.
The XHR way doesn't need any special server side handling.
Currently, we monitor the bytes received on the server side
(and no web server gives you easy access to this information) and
make that available (per session) to the client UA.
At the same time, if I were to use Flash to upload the file, I don't
need server side support to show progress and almost every website
(that deals with large file uploads) today uses Flash to display
upload progress to their users.
I do think browser UI for large uploads is terrible and needs to
be fixed.
I agree!
Yeah, the UI is terrible, but that is about browser implementations and
not about any specification.

I'd love to see browsers provide their own information in a
more noticeable/useful fashion, but I still think surfacing the event
and information allows web developers the option to display such
information in a consistent manner (across browsers) without having
to resort to handling the entire submission process using
XMLHttpRequest. Chrome in fact does show a percentage in the status
bar but how many people have noticed? And with todays browser
trending towards less "chrome" it would mean unless the user has
turned on the status bar this info will not be visible.
