    获取活动项目符号，获取所有项目符号并slideChange检查事件何时发生 - 直到可迭代项目符号等于活动项目符号 - 添加所需的类，然后相反，删除它。

    let swiper = new Swiper(".mySwiper", {
  pagination: {
    el: ".repair-calc-pagination",
    clickable: true,
    renderBullet: function(index, className) {
      return '<span class="' + className + '">' + (index + 1) + "</span>";
    },
  },
});

swiper.on('slideChange', function() {
  const bullets = Array.from(document.querySelectorAll('.swiper-pagination-bullet'));
  const current = document.querySelector('.swiper-pagination-bullet-active');
  let currentAction = 'add';
  document.querySelectorAll('.swiper-pagination-bullet').forEach(bullet => {
    if (bullet === current) currentAction = 'remove';
    bullet.classList[currentAction]('castom-current');
  });
});
    html,

  position: relative;
