find php variable in js function

Hi,

I have 2 chronoform forms :

http://localhost/altair/index.php?option=com_chronocontact&chronoformname=inscription_utilisateur_etape1

and

http://localhost/altair/index.php?option=com_chronocontact&chronoformname=inscription_utilisateur_etape2&nomuser=nomuser

The first form call the second form. In the second form i use a javascript fonction who need to use the nomuser value but nomuser is always not found.

The hmtl code of the second form is :

 
<?php $nomutilisateur = $_GET['nomutilisateur'];
echo $nomutilisateur;
?>
 
<h1>Vos activités</h1>
<label>Type :</label>
	<select name='auteur' id='auteur' onchange='affichage_categorie()'>
		<option value='-1'>Choisir un type</option>
			<?php
					$res = mysql_query("SELECT * FROM jos_comprofiler_field_values WHERE fieldid=54 ORDER BY fieldtitle");
					while($row = mysql_fetch_assoc($res)){
							echo "<option value='".$row["fieldvalueid"]."'>".$row["fieldtitle"]."</option>";
					}
				?>
		</select>						
	<br/>
	<label>Categorie :</label>
	<div id='categorie' style='display:inline'>
		<select name='categorie'> <option value='-1'>Choisir une categorie</option>	</select> 
	</div>	
	<br/>
	<label>Activite :</label>
	<div id='activite' style='display:inline'>
		<select name='activite'> <option value='-1'>Choisir une activite</option> </select> 
	</div>				
	<br/>
	<label>Niveau :</label>
	<div id='niveau' style='display:inline'>
		<select name='niveau'> <option value='-1'>Choisir un niveau</option></select>
	</div>
	<div class="form_item">
		<div class="form_element cf_button">
		<input value="Ajouter" name="button_ajouter" type="button" OnClick="ajouter_activite()"; />
	</div>
	<div class="cfclear"> </div>
	</div>
	<div class="form_element cf_button">
		<input value="Supprimer" name="button_supprimer" type="button" OnClick="supprimer_activite()"; />
	</div>
	<div class="cfclear"> </div>
	</div>
<div class="form_item">
	<div class="form_element cf_button">
	<input value="S'inscrire" name="button_inscription" type="button" OnClick="valider_inscription()";/>
   </div>
</div>

the js part is (voluntary reduced) :

function ajouter_activite(){
				<?php $nomutilisateur = $_GET['nomutilisateur'];?>
				var v = <?php echo $nomutilisateur; ?>;
				alert (v);

The beginning of the html code display nomuser correctly, but my ajouter_activite js function doesn't display the good value when i click the ajouter_button. Where is the problem ?

Well, in finally found a "generic solution" to retrieve this value :

<script type="text/javascript">
    var nom=new Array();
    var valeur=new Array();

    // On enlève le ?
    param = window.location.search.slice(1,window.location.search.length);

    // On sépare le paramètres....
    // first[0] est de la forme param=valeur

    first = param.split("&");

    for(i=0;i<first.length;i++){
        second = first[i].split("=");
        nom[i] = second[0];
        valeur[i] = second[1];
    }
</script>

Whith this code you can retrieve values posted in URL and use it in your js code. I hope that it will help someone one day ... :-)
