如何检查悬停功能中的两个条件

我有一个提问页面，用户要选中3个适当的复选框作为他或她的答案（从6个复选框列表中选择）。然后用户将鼠标悬停在回答按钮（"#check answer btn"）上检查他/她的答案

如果用户将鼠标悬停在$('#check-answer-btn')上，并且选中的复选框少于3个，则我希望某个提醒$('.alert-box2')变淡In。

所以我的问题是，在一个悬停函数中可以有两个条件句吗？我正在发布我尝试过但没有成功的代码。有人能帮我找到解决方案吗？谢谢

       $('#check-answer-btn').hover(function(e){
            var checkboxes = $('.chbx-25b input[type="checkbox"]:checked').length;
            if (checkboxes < 3) {
                $('.alert-box2').fadeIn(200);
            },  $('.alert-box2').stop().fadeOut(200);
            else if (checkboxes >= 3) {
                $('#checkbox-fadebox').fadeIn(200);
            },  $('#checkbox-fadebox').stop().fadeOut(200);
        );

我认为HTML可能太多了，但现在是：
