onclick event

[juicy]

Hi,

I have 4 check box and a textarea. When user check each check box, it will
append text in the textarea. In onclick event, it calls getSurcharge
function and append value in variable output. My problem is I failed to
get value in php variable inside the function.
Please give some idea on the reason of the problem. Thanks.

<script language="JavaScript">
function getSurcharge(id)
{
var output;
if (document.getElementById("chksur1").checked)
{output = output + "<? echo $strSurcharge1; ?>"; }

if (document.getElementById("chksur2").checked)
{output = output + "<? echo $strSurcharge2; ?>"; }

if (document.getElementById("chksur3").checked)
{output = output + "<? echo $strSurcharge3; ?>"; }

if (document.getElementById("chksur4").checked){outpu t = output + "<? echo
$strSurcharge4; ?>"; }
document.getElementById(id).value= output;
}

<?php
$strSurcharge1 = "x1";
$strSurcharge2 = "x2";
$strSurcharge3 = "x3";
$strSurcharge4 = "x4";
?>

<input type=checkbox name="chksur1" onclick="getSurcharge('duties')"
value="<? echo $strSurcharge1; ?>">
<input type=checkbox name="chksur2" onclick="getSurcharge('duties')"
value="<? echo $strSurcharge2; ?>">
<input type=checkbox name="chksur3" onclick="getSurcharge('duties')"
value="<? echo $strSurcharge3; ?>">
<input type=checkbox name="chksur4" onclick="getSurcharge('duties')"
value="<? echo $strSurcharge4; ?>">

<textarea name= "f_duties" id = "duties" cols=100 rows=10>

Your problem is the PHP code is executed on the server before the page is sent
to the client browser. Once the page has been delivered, the javascript runs.
But PHP has already done it's job and terminated.

I move the php code above the getSurcharge function and try with it, it
works, but when I change $strSurcharge1 to a paragraph of text instead of
x1, it couldn't work.

Please give some idea on the case.
Thanks.
