can we disable enable controls of specific div on checkbox

Question

Hi,
How we can disable enable controls of specific div on checkbox click/change,

I have three checkboxes and three divs, what I want to do is, on checkbox one checked enable div one controls (textboxes, select). so far I'm able to get the checkbox enable disable event like the code below

$('#chkbxOne').change(function () {
            var c = this.checked ? 'T' : 'F';
            if (c == "T") {

                alert("Enable");
            }
            if (c == "F") {
                alert("Disable");
            }

        });

 where it alerts Enable, i want to enable all controls of this div,
same for other two divs
