class - Cant uncheck checkbox after adding this jQuery -

the code supposed disable group of checkboxes. there 2 classes of checkbox, if click on one, disables other. problem if change mind , want unchoose (uncheck), not allow me uncheck.

$(".single-checkbox").click(function(){       if ($(this).prop("checked", "checked")) {           $('.deletedone').prop('disabled', true);      } else {           // $(this).prop("unchecked", "unchecked")           // $('.deletedone').prop('disabled', false);                 // $(".single-checkbox").prop("checked", false);       } }); 

i have tried various things in else part of statement no luck. have ideas? there couple of questions on unchecking checkboxes , tried variations in code no luck.

any appreciated.

you setting value instead of checking in if statement.

if ($(this).prop("checked", "checked")) { 

instead, should check if checkbox checked.

if ($(this).is(":checked")) {
