我目前正在使用 Owl Carousel 插件按照下面地址中显示的演示创建多个同步的轮播，尽管在一页上有多个轮播。

http://owlgraphic.com/owlcarousel/demos/sync.html

在处理不同数量的小物品时，我已经成功地复制了轮播，并让它们除了一个特定的问题之外独立工作。当我在顶部轮播中创建的项目多于底部并在底部轮播显示的项目之外选择一个小项目时，两个小项目轮播都会移动以显示该项目（在顶部未选择）

也就是说，用下面的代码，从顶部轮播中选择“20”，然后观看底部轮播的小物品轮播右移显示20项。然后在顶部小物品轮播中选择项目3，观看底部小物品旋转木马再次向后移动。奇怪的是，当底部轮播的 jQuery 参数中的项目数量增加时，它根本不会影响顶部的项目。

我确定这是一个需要为其分配不同名称的变量的情况，但我无法终生找出问题所在。有什么想法吗？

在我自己看过之后，这是一个在脚本的第二个副本中重命名“current”、“num”和“number”变量的简单案例。现在给他们起个更有意义的名字！！

  /* carousel two */
  var sync3 = $("#sync3");
  var sync4 = $("#sync4");

  sync3.owlCarousel({
    singleItem : true,
    slideSpeed : 1000,
    navigation: true,
    pagination:false,
    afterAction : syncPosition2,
    responsiveRefreshRate : 200,
  });

  sync4.owlCarousel({
    items : 15,
    itemsDesktop      : [1199,10],
    itemsDesktopSmall     : [979,10],
    itemsTablet       : [768,8],
    itemsMobile       : [479,4],
    pagination:false,
    responsiveRefreshRate : 100,
    afterInit : function(el){
      el.find(".owl-item").eq(0).addClass("synced");
    }
  });

  function syncPosition2(el){
    var current2 = this.currentItem;
    $("#sync4")
      .find(".owl-item")
      .removeClass("synced")
      .eq(current2)
      .addClass("synced")
    if($("#sync4").data("owlCarousel") !== undefined){
      center2(current2)
    }
  }

  $("#sync4").on("click", ".owl-item", function(e){
    e.preventDefault();
    var number2 = $(this).data("owlItem");
    sync3.trigger("owl.goTo",number2);
  });

  function center2(number2){
    var sync4visible = sync4.data("owlCarousel").owl.visibleItems;
    var num2 = number2;
    var found = false;
    for(var i in sync4visible){
      if(num2 === sync4visible[i]){
        var found = true;
      }
    }

    if(found===false){
      if(num2>sync4visible[sync4visible.length-1]){
        sync4.trigger("owl.goTo", num2 - sync4visible.length+2)
      }else{
        if(num2 - 1 === -1){
          num2 = 0;
        }
        sync4.trigger("owl.goTo", num2);
      }
    } else if(num2 === sync4visible[sync4visible.length-1]){
      sync4.trigger("owl.goTo", sync4visible[1])
    } else if(num === sync4visible[0]){
      sync4.trigger("owl.goTo", num2-1)
    }

  }
