//radio选择填充,字段

            $(‘:radio[name="‘ +F + ‘"]‘).change(function () {
                var str = $(this).val();
                $(‘.‘ + F).each(function (i) {
                    console.log(radioArray[v]);
                    $(this).val(str[i]);
                })
            })
        })(radioArray[v])
    }
