Initialisation Select avec Ajax (php)

Hello,
I have a little script that display or hide input field depending on the
choice of a select.
It is working fine, but i can not initialise the default value of the select
and have it display the correct input box...
main file:
[CODE]<script language="JavaScript" src="modules/metro/combos.js"
type="text/javascript"> </script>
....
<select name="Ctrltype" id="Ctrltype" onChange="newmenuderoulant(this,'<?php
echo $IdEquipCtrl; ?>')">
<option>--select--</option>
<option value="Lab"<?php if ($rowcontrol[Ctrltype]=="Lab") {echo "
selected";} ?>>Lab (Min-Max)</option>
<option value="Maintenance"<?php if
($rowcontrol[Ctrltype]=="Maintenance") {echo " selected";} ?>>Maintenance
(?)</option>
</select>
.....
<td> <div id="combo2"></div> </td>[/CODE]
The ajax looks working fine, display is ok, when you switch the select to
one value to another, but not at the first call of the page...
Is the error coming from this line:
http.onreadystatechange = displaylist2; ??????
ajax file combos.js :
[CODE]function creerConnexion() {
var connexion;
connexion = window.XMLHttpRequest
? new XMLHttpRequest() :
new ActiveXObject("Microsoft.XMLHTTP");
return connexion;
}
var http = creerConnexion();
function newmenuderoulant(objselect,idctrl) {
var Ctrltype =objselect.options[objselect.selectedIndex].value;
//alert(Ctrltype);
if (idctrl!=null)
http.open('get', 'modules/metro/ajax.php?Ctrltype='+Ctrltype+'&am
p;idctrl='+idctrl);
else http.open('get', 'modules/metro/ajax.php?Ctrltype='+Ctrltype);
http.onreadystatechange = displaylist2;
http.send(null);
}
function displaylist2(){
if(http.readyState == 4){
var response = http.responseText;
document.getElementById("combo2").innerHTML=response;
}
else
{
/*alert('Etape '+http.readyState);*/
}
}[/CODE]
in the ajax.php file i just create the html for the field that goes in the
div id combo2 ...
Thanks for your support!
