中心 div 上的 BXslider 活动类，带有 5 张幻灯片

Question

我真的在这个问题上拉了我的头发。我在 bxslider 中有 5 张幻灯片，我试图在页面上的 5 张幻灯片中的第 3 张幻灯片上有一个活动类，当第 1 张幻灯片加载时它会这样做......现在当我第一次单击下一个按钮时活动类不会转到下一个元素。它停留在当前幻灯片上，然后第二次移动到下一张幻灯片 我点击下一个按钮。所以我认为 next() 函数不起作用。还是我做错了什么？

jQuery(function($){
	
var slider = $('.bxslider').bxSlider({
 minSlides: 1,
  moveSlides:1,
  maxSlides: 5,
   pager:false,
  controls:false,
  slideWidth: 360,
  slideMargin: 0,
    onSlideBefore : function($slideElement, oldIndex, newIndex){ // your code here 

$(".bxslider li").removeClass("active-slide");
        $slideElement.next().addClass("active-slide");
},
    onSliderLoad:function(index){
       
$(".bxslider li").eq(1+$(".bxslider .bx-clone").length/3).addClass("active-slide");
    }
});
   
    
$('#slider-next').click(function(){
  slider.goToNextSlide();
    
  return false;
});
$('#slider-prev').click(function(){
  slider.goToPrevSlide();
  
  return false;
});

});

.active-slide{
background:#f00 !important;
}

.scorboard {
