    $(document).ready(function(){
        var a =$(".box ul li:gt(3):not(:last)");
            a.hide();
        $(".boxdown").click(function(){
            if(a.is(':visible')){
                 a.slideUp('fast');
                 $(this).removeClass('up');
            }else{
                a.slideDown('fast').show();    
                $(this).addClass('up');
            }            
        });
    });
    </script>

当一个页面需要多个这种功能，就需要用到遍历：

$(".contentBox .swiper2 .scheduleBox .day").each(function(){
            var a =$(this).find(".dayBox dl dd:gt(1)");
            a.hide();
            $(this).find(".showHide").click(function(){
                if(a.is(':visible')){
                     a.slideUp('fast');
                     $(this).removeClass('up');
                     $(this).find("span").text('展开详细');
                     $(this).find("i").css("transform","rotate(-90deg)");
                }else{
                    a.slideDown('fast').show();    
                    $(this).addClass('up');
                    $(this).find("span").text('收起');
                    $(this).find("i").css("transform","rotate(-270deg)");
                }            
            });
        })
