well what @gde has is correct, another way is you can just use the following in your checkboxes to make it work,

<cfsetting showdebugoutput="false">
<form id="form' name="form">
<input type="checkbox" id="Checkbox1" value = "1" />
<input type="checkbox" id="Checkbox2" value = "2" />
<input type="checkbox" id="Checkbox3" value = "3" />
<input type="checkbox" id="Checkbox4" value = "4" />
<input type="button" id="demo" value = "Demo" />
</form>

<script type = "text/javascript" src = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.7.2.min.js"></script>
<script type="text/javascript">
    $(document).ready(function() {
		$(document).on("click", "#demo", function () {
			$("input:checkbox:not(:checked)").each(function () {
				$('<input>').attr({type: 'text',id: $(this).attr("id"),name: $(this).attr("id"),value: $(this).val()}).appendTo('form');
				//alert("Id: " + $(this).attr("id") + " Value: " + $(this).val());
			});
		});
	});
</script>

Open in new window

for this $('<input>').attr({type: 'text', you can make it use $('<input>').attr({type: 'hidden',

Best practice to simply provide a value if none is passed.
