    <script>
function countChecked() {
  var n = $("input:checked").length;
  $("div.message").text(n + (n <= 1 ? " is" : " are") + " checked!");
}
 
$(document).ready(function(){
  countChecked();
  $(":checkbox").click(countChecked);
});
    </script>
  </head>

      <input type="checkbox" name="newsletter" checked="checked" value="Hourly">Hourly</input>

$(":checkbox[name='newsletter']").click(function(){
	var objChecked = $("input[name='newsletter']:checked"),
		n = objChecked.length,
		tab = [];
 
	for(var i = 0; i < n; i++){
		tab.push("index = ",
				 $(objChecked[i]).index(":checkbox[name='newsletter']"),
				 ", valeur = ",
				 $(objChecked[i]).val(),
				 "<br/>");
	}
 
	$("div.message").html(tab.join(""));
});
