Yes.

Is the script embedded in the resulting html source or
is it in a .js file and included ?

Hans.

Hi Hans.

Thanks for replying.

The script is embeddeded in the resulting php file.

Get the hrmldata with a HTTP component like TIdHTTP or
TNMHTTP. You could even use TCppWebBrowser.

Then parse the data. Just look for <script> and so on.

Hans.

Thanks Hans. I already know how to download the file but embedded in the
html file is the actual JavaScript code, not exactly what is displayed to
the public on the website itself.

Sounds like you will probably have to actually execute the script in order
to know what output it produces.


Gambit

Part of the script looks something like

if (document.all)
document.all.countDownText.innerText = secsToMins(countDownTime);

else if (document.getElementById)
document.getElementById("countDownText").innerHTML =
secsToMins(countDownTime);

would it be possible to get the value of  the CountDownTime variable?

You did not show where it is declared or assigned.

Hi Remy :)

Here is the piece of the html source:

the script:

<script language="JavaScript" type="Text/JavaScript">
<!--
var countDownInterval = 46;
var countDownTime = countDownInterval + 1;

if (document.all||document.getElementById)
countDown();
else
window.onload = countDown;

function countDown() {
countDownTime--;
if (countDownTime == 0) {
countDownTime = countDownInterval;
window.location.reload();
return;
}

else if (countDownTime < 5)
countDownTime = countDownTime + 00000;
if (document.all)
document.all.countDownText.innerText = secsToMins(countDownTime);
else if (document.getElementById)
document.getElementById("countDownText").innerHTML =
secsToMins(countDownTime);
counter = setTimeout("countDown()", 1000);
}

function secsToMins(theValue) {
var theMin = Math.floor(theValue / 60);
var theSec = (theValue % 60);
if (theSec < 10)
theSec = "0" + theSec;
return(theMin + ":" + theSec);
}
// -->
</script>

the part of the html source involved with actually displaying the info looks
something like,

<tr>
<td class="td01" height="63" colspan="3" valign="middle" align="center">
<br>
Count down display (<span id="countDownText"></span>)<br>
<br>
</td>
</tr>

That script dynamically changes the page's text 47 times.  Do you want to
retreive all 47 text messages that get displayed to the user?

I just need to get the first instance, then I can continue the countdown
timer using a TTimer.

Just load the script/html into a TStringList and then locate and parse out
the lines that declare the countDownInterval and countDownTime variables.


Gambit

Remy and Hans, thanks for taking your time to help.

Working with a TStringList is a good idea.  I now see exactly  how the site
code works. Got lucky the first try when trying to match the site's text
with html code, everything matched but then lead myself astray.  I was using
IE's view source menu command without actually refreshing the page before
each view of the source, the countDownInterval changes with every refresh,
duh! ;) . My knowledge of html is very minute, took a while to understand
the whole page's code.

Thanks again for your time :)
