code du decompteur:
		
		
			
			<head> 
<script type="text/javascript"> 
var valeur_origine = 5; 
var valeur = valeur_origine 
var x; 
function Init() { 
window.document.form.compteur.value=valeur; 
x = window.setInterval('Decompte()', 1000); 
} 
function Decompte() { 
(valeur > 0) ? (window.document.form.compteur.value = --valeur) : (go()); 
} 
function go(){ 
window.clearInterval(x); 
window.document.form.compteur.disabled=false; 
window.document.form.compteur.value="GO"; 
} 
window.onload = Init; 
</script> 
</head> 
<body> 
<form name="form"> 
<input type="button" value=" compteur " name=compteur disabled=true > 
</form> 
</body>
