Hi guys

i have comment form code (in black colour) below, user type the comment in TEXTAREA, and click the Submit button

i want to add DROP DOWN LIST BOX before it, that user can choose, and add that DROP DOWN value with the text in TEXTAREA into database, so just like prefix in forum

i already tried below code (in red), but still not working, please help guys what is the right code

<script language="javascript" type="text/javascript">


$("#form_submit").click(function() {
document.getElementById("form_submit").disabled = true;
checkcomment = trim(document.comment_form.message.value);

if (checkcomment.length > 0) {
var msgPrefix = document.forms["comment_form"].elements["message_prefix"].options[document.forms["comment_form"].elements["message_prefix"].selectedIndex].value;
value = "["+msgPrefix+"] "+value;

else {
alert("Please type some text");
document.getElementById("form_submit").disabled = false;

function comment_done() { }
function comment_submit()
type: "POST",
url: "/targetfile.php",
data: $("#comment_form").serialize(),
success: function(data){
if (data == "SUCCESS") {
document.comment_form.message.value = "";
setTimeout (CommentAjax,0);
else {
alert("Error: "+data);


<form id="comment_form" name="comment_form" method="post">
<input type="hidden" name="heu" value="addreply" />
<input type="hidden" name="muser" value="' . $this->muser . '" />
<input type="hidden" name="modid" value="' . $this->douid . '" />
