Progress bar

[Simon]

Hello,

I would like to know if there is a way to display a progressbar while
loading a page.
(We developped our application in Caché (intersystems), some functions need
some time to
calculate&displ ay data, in the mean time I don't want users to stare at an
internet explorer in whitch nothing happens, i want them to see that
something is happening and even better, the status of loading.)

I saw on the internet that javascript won't work because it has no insight
to the bytes
received. (But ok, i can do without that information.)
I've tried to use an animated gif, (same gif you see when starting windows
for example), or just the text: "please wait...", but then the problem is
that although I can hide and show it through Javascript, it won't be shown
before the page is completely loaded. In a script i show the text: please
wait. In the body i use the onload-event to hide the text but that wont work
because the script won't be executed before the onload event is triggered.

I can't find a way to trigger an onbeforeload-event. (For the script that
displays Please wait)

Any ideas?

Thanks,
Simon

You really, *really* should use a little effort. You made it all the
way to Google Groups, but couldn't search Google for "javascript
progress bar?"

Anyway, you could an XMLHttpRequest to initiate the request, and it can
notify you when that request is complete.

Nothing against the idioma de Española, but that code is ridiculously
complex. And it doesn't need to be...

http://www.dynamicdrive.com/dynamici...lprogress2.htm for example.

Although, I would still use an XHR, and update the width of a DIV or
other block element whilst the XHR runs through its onprogress event.
No clue if Internet Explorer supports that in version 7. I'll venture a
guess and say "no."
