在mozilla中,BX滑块幻灯片预览不起作用

当我在Mozilla中滑动预览图像时,它不工作,但在chrome中工作良好。有人能帮我吗???

有没有办法在mozilla中找到问题??

var $this = $(this);
    var realSlider = $this.find('.product-detailslider');
    var realThumbSlider= $this.find(".product-detailslider-pager");

    realSlider.bxSlider({
        Height: 600,
        speed:1000,
        pager:false,
        nextText:'',
        prevText:'',
        infiniteLoop:false,
        hideControlOnEnd:true,

        onSlideBefore:function($slideElement, oldIndex, newIndex){
          changeRealThumb(realThumbSlider,newIndex);
        }
    });

    if ($this.data('bxSlider')) { return; }
    realThumbSlider.bxSlider({
      maxSlides: 3,
      minSlides: 3,
      slideWidth: 110,
      slideMargin: 3,
      moveSlides: 1,
      mode: 'vertical',
      pager:false,
      speed:1000,
      infiniteLoop:false,
      hideControlOnEnd:true,
      nextText:'<img src="'+BASE_URL+'/images/arrow-down.jpg"',
      prevText:'<img src="'+BASE_URL+'/images/arrow-up.jpg"'     
    });
