My AJAX response from my PHP flashes briefly then goes away.
Appreciate it if someone can give me some suggestions on what I need
to do to correct this problem.
Thanks..

Hard to guess anything without any code provided.
Please provide the minimum code needed to reproduce the issue.

What does "briefly flashes" mean? Not outside your bedroom window I hope.
A sensible problem description [1] and some context would help.
[1] One place I used to work at, there was one irritating person who
came into my office from time to time and said: "It doesn't work". My
usual response to him was "Have you been to the Doctor about it?". He
eventually got the point - please try to also.

Here is my Code. This is the call from my main routine
<input name="btnSearch" type="submit" id="btnSearch"
onclick="getData('results')", value="Submit Search" />
This is the function that makes a "Synchronous" call to APAX.. I'm
using Synchronous to try to debug my problem.
target points to the output area in my main routine, <div
id-'results'></div>
function getData(target) {
var serverPage = "getCensusData.php";
var parmStr = "lastname=Jul%";
var obj = document.getElementById(target);
processSJAXPost(serverPage, parmStr, obj);
}
Here is my SJAX call.
function processSJAXPost(serverpage, parmStr, obj) {
xmlhttp = getxmlhttp();
xmlhttp.open("POST", serverpage, false);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-
urlencoded");
xmlhttp.setRequestHeader("Content-length", parmStr.length);
xmlhttp.setRequestHeader("Connection", "close");
xmlhttp.send(parmStr);
obj.innerHTML =
xmlhttp.responseText;;
}
My PHP routine is nothing but an single statement, <?php echo
"getData()"; ?>
Now, I'm getting a result from my PHP routine but it "flashs" and goes
away.
Thanks for the help..

Briefly flashes means that the results of the echo statement in my php
routine, "flash" on my main page for less then a second.
Sorry for not posting the code in my first response. I know what you
mean with your dissertation. I was hoping the solution would be simple
and I wouldn't have to post code.
Thank you very much for your response. Hopefully the code I posted
will help...

PHP knows nothing about the browser end. PHP sends data to the browser;
if it only flashes, one of two things are happening:
1) The javascript is doing something odd - follow up in comp.lang.javascript
2) The html is invalid - try alt.html.
In either case - if the data gets to the browser, it is not a PHP
problem. PHP is server-side only.

That's true. My PHP is working fine. BUT, it takes two to tango! I
doubt that there are too many people who write ONLY PHP code. A lot
also work on the client side and I was hopping some of those could
give me some suggestions.
Thanks for the response..

Please see above. It doesn't matter how many people write in whatever
other languages. This is a PHP newsgroup, and where the PHP experts
hang out. If your PHP code is working, you're in the wrong group.
Please ask in a more appropriate newsgroup.

Is this button within a <form> element?

If so then do a return false; here.

Also:
<input name="btnSearch" type="submit" id="btnSearch"
onclick="getData('results')", value="Submit Search" />
What is that comma (,) doing after onclick="getData('results')" ?
And the closing tag /> indicates an XML file. What is the doctype?

Is this a typo?
As others already wrote: Here you have a submit button. So it does two
things, when clicked:
Calls the JavaScript function
*and*
submits the form (if it's within a form).
That triggers two requests, where I guess, the response of the
form-submit "overwrites" the response from the AJAX call.
Solution: either use a <input type="button" />, which wouldn't submit
the form. Or use your submit-button and return false from the click
handler to suppress the submitting of the form. But this makes only
sense, if you want a fallback in submitting the form, if JavaScript is
turned off or your JavaScript functions return a correct true or false,
depending whether the call succeeded or not.
> <div id-'results'></div>
^
Is this a typo? With this, I don't think, you would have an element with
the id "results".

I changed the button to a type button and all works fine
As of <div id='results"></div>, this is the target for my innerHTML
AJAX response..

I hope it's actually:
<div id='results'></div>
or:
<div id="results"></div>
and not really:
<div id='results"></div>

Yes, I know ;). But you had:
<div id-'results'></div>
^
with a minus instead of an equal sign in your original posting.
