        {
            var CustID = hidCID.value;
            CustArray = CustID.split("");

            alert('CustID is :' + CustID );
            alert('CustArray is :' + CustArray );
            if (CustID == null || CustID=="") {
                $(".checkBoxClass:checked").each(function () {
                    alert("Null");
                    //CustomerIDArray = $(this).val();
                    //alert(CustomerIDArray);
                    alert('value : '+$(this).val());
                    hidCID.value = $(this).val();
                });
            } else {
                alert("Not Null");

                $(".checkBoxClass:checked").each(function () {
                    alert($(this).val());
                    //CustomerIDArray = CustomerIDArray + "," + $(this).val();

        }
        //$('#hfCustomerID').val(allSelectedValues);

要删除数组项，请使用Array.splice(startIndex, deleteCount)。

let elIndex = custArray.indexOf(deleteId);
custArray.splice(elIndex, 1);
