[yeah, I did not quote 'cause every news reader shows the thread easily,
anyway. Why waste lines? - I tried to write Randy back via email but the
email addr doesn't go. So I post again. ]
I pulled off the JS->PHP document.body.appendChild() hack, only to find
that after setting an element in the page to the result of the PHP mySQL
Query, I read the element with Javascript and it is "not yet changed".
Some kind of latency problem ( guessing). In other lives I have
initiated an event (chaining) and then handled the response in the
subsequent event. I do not know how to do that in this
HTML/Javascript/PHP combo.
TO make progress I have reverted to a simple form action o nthe intro
page, with the SQL in a target PHP file, then redirect to the main page
upon success.
Now I face coding the main page, where I DO want dynamic updates (using
"dynamically loaded scripts" apparently). I have a simple version
already, using Javascript only. Simple meaning 500 lines of js. I now
need the MySQL because the real db engine has deeper requirements than
my JS demo handles.
I would be willing to call Perl to do the MySQL, but the main point is
not to jump around to URLs and redraw the page. I thought the
dynamically loading script would be a neat solution. But reading the
result is now apparently a problem.
Or I need another way to pass back the result other than: setting an
element in the page to a value (latency problem); or passing it through
a URL (causes a redraw of the page). I have noticed that sometimes the
browser is smart and sees that the URL is the same and does a smart
refresh, but that is not guranteed.
So I do appreciate the insights. As I said, I am new to this. Further
discussion is welcome, or I'll start a new thread on the chaining topic
or something...
best regards -brian
