il faut que tu apprennes le javascript.

donne une id à tes champs
tu pourras les tester comme ceci :

document.getElementById('id_champ').value = c'est la valeur du champ dont l'ID est id_champ

pour les boutons radios, lis la doc javascript, tu trouveras

Bon Courage

<script type="text/javascript" >

function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
{
alert(alerttxt);return false;
}
else
{
return true;
}
}
}

function validate_form(thisform)
{
with (thisform)
{

if (validate_required(date_depart_vol,"date_depart must be filled out!")==false)
{date_depart_vol.focus();return false;}



}
alert(date_depart_vol);
}


function test_date(){
var end = new Date(document.getElementById('date_retour_vol').value);
var start = new Date(document.getElementById('date_depart_vol').value);
var today = new Date();
var is_valid = (start > today && start < end);
if(!is_valid){
alert("The chosen date are not valid");
}
return is_valid;
}


function formCheck(form){
var fieldRequired = Array("aeo_depart","aeo_arrive","date_depart_vol","date_retour_vol");
var fieldDescription = Array("aeroport de depart","aeroport d'arrive","date de depart","date de retour");
var alertMsg = "Veuillez completer ces zones:\n";

var l_Msg = alertMsg.length;

for (var i = 0; i < fieldRequired.length; i++){
var obj = form.elements[fieldRequired[i]];
if (obj){
switch(obj.type){
case "select-one":
if (obj.selectedIndex == -1 || obj.options[obj.selectedIndex].text == ""){
alertMsg += " - " + fieldDescription[i] + "\n";
}
break;
case "select-multiple":
if (obj.selectedIndex == -1){
alertMsg += " - " + fieldDescription[i] + "\n";
}
break;
case "text":
case "password":
case "textarea":

alertMsg += " - " + fieldDescription[i] + "\n";
}
break;
default:
}
if (obj.type == undefined){
var blnchecked = false;
for (var j = 0; j < obj.length; j++){
if (obj[j].checked){
blnchecked = true;
}
}
if (!blnchecked){
alertMsg += " - " + fieldDescription[i] + "\n";
}
}

je n'ai pas regardé ton code, trop long et mal structuréà mon goût.

Utilise la console d'erreur de Mozilla Firefox pour debugger ton javascript (OUTIL => Console d'erreur)
