Question

Having an unpredicted outcome using the && logical operator. If I link more than 2 expressions, the if clause fails. Is there some limit to the number of expressions that can be concatenated using &&?

            if (tTellerProN.checked && tCareProN.checked && tSalesProN.checked) {
                $(flListEmpty).empty();
                $(flListEmpty).append($('<option></option>').val(0).html("Select Role"));
                $('.fl_list1 .list4').each(function (index) {
                    $(flListEmpty).append($('<option> </option>').val(index).html($(this).text()));
                })
            }

No, there is no limit. Your expression requires that all three checked values are true, otherwise it will return false. One of them must be false (or not true), that’s why your if is failing.

For the record: && is part of the javascript language, not the jQuery library.
