这是一个测验，一切正常，但是当我检查从按钮到顶部的单选按钮时，一切都坏了。我想这样的事情：当我在第一个问题中检查是或否，我的下一个按钮被隐藏。在那之后，当我检查是或者在第二个问题中，我的按钮旁边是可见的。重要提示：必须在第一个问题中检查一个单选按钮！如果检查了第一个问题的任何单选按钮，并且我从第二个问题检查了带有val（）== no的按钮，则将显示另一个div，并且将隐藏下一个按钮。检查此div中的任何值后，将显示下一个按钮。 Q（）;

          function q(last) {
                var last = last;
                //fdgdf

            // if($('.item.active .ascuns').length==2){
            //     console.log($('.item.active .ascuns'));
            // }

            //fsdfdsfds
                 $('.item.active input[type=radio]').on('ifChecked', function (event) {

                        ($(this).attr('data-attr-red-q3') === 'no' && $(this).val() === "Nu") ||
