Bonsoir :)

J'ai un gros soucis (ou alors je vois déjà trouble à cette heure)
J'utilise les objets XHR dans un formulaire php afin de mettre un jour un textarea dynamiquement.
J'ai donc une fonction utilisant un objet XHR comme suit :

<SCRIPT language="javascript">

function traitement ( ){

	//alert("copucou");
	var checkBox = document.getElementById("select_all");
	var list	 = document.getElementById("select_file");
	var select	 = null;

	if ( checkBox.checked )
	{
		alert("all");
		select = "all";
	}
	else if ( list[list.selectedIndex].value != -1 )
	{
		alert("un element : "+list[list.selectedIndex].value);
		select = list[list.selectedIndex].value;
	}

	if ( select != null )
	{
		// All values are OK, launch the request
		var xhr_object = null; 
	     
	   if(window.XMLHttpRequest) // Firefox 
	      xhr_object = new XMLHttpRequest(); 
	   else if(window.ActiveXObject) // Internet Explorer 
	      xhr_object = new ActiveXObject("Microsoft.XMLHTTP"); 
	   else { // XMLHttpRequest non supporté par le navigateur 
	      alert("Votre navigateur ne supporte pas les objets XMLHTTPRequest..."); 
	      return; 
	   } 
	 
	   xhr_object.open("POST", "./traitement/extract.php", true);
	     
	   xhr_object.onreadystatechange = function() { 
	      if(xhr_object.readyState == 4) {
			 alert(xhr_object.responseText); // DEBUG MODE
	         //eval(xhr_object.responseText);
		  }
	   } 
	 
	   xhr_object.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
	   var data = "archive="+select;
	   alert(data);
	   xhr_object.send(data);
	}
}

</SCRIPT>
