Question

我正在使用flex-slider开发Slider。我想到了将两个flexsliders同步到一个的想法，就像处理Owl-carousel一样。当柔韧性字幕与图像进行动画处理时，我必须使用两个flexslider，因为我希望柔韧性字幕动画不同于图像动画。我已经在java.time.LocalDateTime的帮助下同步了它们但是现在我陷入了两点：

1）我也希望箭头也同步。如您在我的代码中看到的，我将flex-direction-navs分组了。现在，我想在单击一个按钮时更改两个幻灯片，但这不起作用，因为它上面有层次。

2）我希望自定义定位按钮处于活动状态，具体取决于活动幻灯片。例如，我在第三张幻灯片上，我希望第三个定位锚标签处于活动状态，例如颜色变化等。

希望我清楚地解释了我的问题。如果您需要更多信息，请在下面评论。

        if (slider.currentSlide != slideToInt) {
          slider.flexAnimate(slideToInt) //move the slider to the correct slide (Unless the slider is also already showing the slide we want);
        }

您可以通过创建自己的箭头来应用与链接相同的逻辑。删除默认的监听器，然后添加自己的侦听器以移动滑块。

对于活动链接，只需添加更多JS即可切换类。

在此示例中，您可以轻松地使用CSS随意调整位置：

jQuery(document).ready(function($) {

  $('#main-slider').flexslider({
    animation: "slide",
    slideToStart: 0,
    start: function(slider) {
      $('a.slide_thumb').click(function() {
        $('.active').removeClass('active');
        $(this).addClass('active');
        $('.flexslider').show();
        var slideTo = $(this).attr("rel") //Grab rel value from link;
        var slideToInt = parseInt(slideTo) //Make sure that this value is an integer;
        if (slider.currentSlide != slideToInt) {
          slider.flexAnimate(slideToInt) //move the slider to the correct slide (Unless the slider is also already showing the slide we want);
        }
      });
      $('.flex-prev').click(function(e) {
        e.preventDefault();
        $('.active').removeClass('active');
        $('.flexslider').show();
        var c = slider.currentSlide;
        if(c!=0) {
          c--;
          slider.flexAnimate(c);
          $('.slide_thumb[rel='+c+']').addClass('active');
        } else {
          slider.flexAnimate(3);
          $('.slide_thumb[rel=3]').addClass('active');
        }
      })
       $('.flex-next').click(function(e) {
       e.preventDefault();
        $('.active').removeClass('active');
       $('.flexslider').show();
        var c = slider.currentSlide;
        if(c!=3) {
          c++;
          slider.flexAnimate(c);
          $('.slide_thumb[rel='+c+']').addClass('active');
        } else {
          slider.flexAnimate(0);
          $('.slide_thumb[rel=0]').addClass('active');
        }
      })

        var slideToInt = parseInt(slideTo) //Make sure that this value is an integer;
        if (slider.currentSlide != slideToInt) {
          slider.flexAnimate(slideToInt) //move the slider to the correct slide (Unless the slider is also already showing the slide we want);
        }
      });
      $('.flex-prev').click(function(e) {
      e.preventDefault();
