slight improvement for Pim Jager (assuming you want an array of return values):

function getCheckedNames(){
 var arr = new Array();
 var $checked = $('[@name=newsletter]:checked');
 $checked.each(function(){ 
  arr.push($(this).val());
 });
 return arr;
}


and with improvement from duckyflip:

function getCheckedNames(){
  return jQuery('[@name=newsletter]:checked').map(function(){
   return this.value;
  });
}

var values = $.makeArray($(":checkbox:checked").map(function(){
   return this.value 
})).join(', ')

alert(values)

It's not easy to see what you are trying to do here, but I assume this is what you need:

$("input:checked").each(function() {
   alert($(this).val());
});

I think this is what you need:

function updateChecked(){
 var arr = new Array();
 $('input:checkbox:checked').each( function() {
   arr.push($(this).val());
 });
 var checkboxesText = arr.join(', ');
 var moreText = (arr.length <= 1 ? " is" : " are") + ' checked!';
 $('div').text(checkboxesText + moreText);
}

This will cause the div text to look something like "Hourly, checked daily!"
