Question

我正在研究两种类型同时工作的滑动滑块，即“分数”和“幻灯片更改时的进度条”。我已完成进度栏“分数类型中的问题”。我正在使用swiper版本（4.5.0），并从 enter link description here 其中，使用Swiper（3.0.6）version.code与该版本不兼容。计数器不工作。我已经完成了Progreesbar类型的操作，但是卡住了违规类型。请为我指出正确的方向，并提前致谢。

输出：幻灯片上的分数更改

已完成代码更新：codepen

添加的分数代码不起作用：codepen

代替在Swiper的启动过程中使用onSlideChangeStart，您可以像下面这样设置更改功能：

mainslider.on('slideChange', function () { ... }

或

mainslider.on('transitionStart', function () { ... }

结果：

$(document).ready(function() {

  var mainslider = new Swiper('.slider-main', {
    pagination: {
      el: '.swiper-pagination',
      type: 'progressbar',
    },
    navigation: {
      nextEl: '.swiper-button-next',
      prevEl: '.swiper-button-prev',
    },
  });

  var counter = $('.fraction');
  var currentCount = $('<span class="count">1<span/>');
  counter.append(currentCount);

  mainslider.on('transitionStart', function () {
    var index = this.activeIndex + 1,
        $current = $(".photo-slide").eq(index),
        $c_cur = $("#count_cur"),
        $c_next = $("#count_next"),
        dur = 0.8;

    var prevCount = $('.count');
    currentCount = $('<span class="count next">' + index + '<span/>');
    counter.html(currentCount);
  });

});

我删除了TweenMax部分。
