@requires:
jquery

@does:
This tiny plug-in adds and removes a 'checked'-class to input[type=checkbox]'s parents. Very useful if you want to style the entire wrapping <label>-element when its child-checkbox is checked.

@howto:
jQuery('form').checkedCheckboxParent(); would apply the plug-in to every checkbox in 'form'.

@exampleHTML:
<p>
	<label>
		<input type="checkbox" name="dummy" /> Click me to try it
	</labe>
</p>

@exampleJS:
jQuery('#jquery-checked-checkbox-parent-example').checkedCheckboxParent();
***/
jQuery.fn.checkedCheckboxParent = function () {
	return this.each(function () {
		jQuery(':checkbox', this).each(function () {
			var check = $(this);

			var checkParent = function () {
				if (check.is(':checked')) {
					check.parent().addClass('checked');
				}
				else {
					check.parent().removeClass('checked');
				}
			};

			checkParent();
			check.click(checkParent);
		});
	});
};
