具有鼠标滚轮滚动插件速度的Owl旋转木马

Question

我在Mouse Wheel插件中使用了Owl Carousel 2，因为网站展示了如何实现它：https://owlcarousel2.github.io/OwlCarousel2/demos/mousewheel.html

下面是我的示例：https://z-testing.000webhostapp.com/_owlcarousel/

这是我的代码：

owl.on('mousewheel', '.owl-stage', function (e) {
  if (e.deltaY>0) {
      owl.trigger('next.owl');
  } else {
      owl.trigger('prev.owl');
  }
  e.preventDefault();
});

我的问题是，滚动它不流畅，它非常快，一次滚动通过6-10张幻灯片，这是不可用的。我希望它尽可能像鼠标滚轮滚动一样平滑。

我找到了一个集成了鼠标滚轮插件的lightbox插件，并检查了他们是如何做到这一点的，但我只是不知道如何在我的代码中使用它，你能帮助我吗？

这是插件：http://fancybox.net

您可以查看Image gallery (ps, try using mouse scroll wheel)弹出式图库示例。

如果你下载这个插件，你可以看到他们以这种方式实现了鼠标轮插件：

if ($.fn.mousewheel) {
    wrap.bind('mousewheel.fb', function(e, delta) {
        if (busy) {
            e.preventDefault();

        } else if ($(e.target).get(0).clientHeight == 0 || $(e.target).get(0).scrollHeight === $(e.target).get(0).clientHeight) {
            e.preventDefault();
            $.fancybox[ delta > 0 ? 'prev' : 'next']();
        }
    });
}

你能帮我让它在Owl Carousel上正常工作吗？

需要使用smartSpeed函数来设置滚动速度。

​

var owl = $('.owl-carousel');
$('.owl-carousel').owlCarousel({
  loop:true,
  margin:0,
  nav:true,
  smartSpeed:1000,
  responsive:{
      0:{
          items:1
      },
      600:{
          items:1
      },
      1000:{
          items:1
      }
  }
});
owl.on('mousewheel', '.owl-stage', function (e) {
  if (e.deltaY>0) {
      owl.trigger('next.owl');
  } else {
      owl.trigger('prev.owl');
  }
  e.preventDefault();
});
$(document,window,'html').mouseleave(function(){
  $("#footer").fadeOut();
}).mouseenter(function(){
  $("#footer").fadeIn();
});
$(function(){
  $("#header").load("includes/header.html");
  $("#footer").load("includes/footer.html");
});

body { padding-top: 0px;}
