[Javascript] Timing Issues

[Chris Tifer]

First, the obvious thing would be to page your results so that there's not
so much info in one shot unless it's absolutely neccessary (in most cases,
it
is NOT neccessary to give them all the info on one page).

If that's not an option, a table won't render until it's complete, so your
best best
(although it will tremendously increase HTML file size) would be to put each
individual record in it's own table so that way by the time the next record
was being written out, the previous table would be complete.

Now I don't know about PHP, but in ASP, you can set buffering on code
and if you have that turned on, nothing will be sent to the client until the
entire
bit has been run.

To send the processed HTML to the client, I would use:

response.flush

Hope that might help a little.
