swiper.js 的进度条自定义

  • 772

在此处输入图像描述

我欢迎大家！请告诉我如何自定义此进度条。我正在使用 swiper.js。使其在活动幻灯片上工作。现在，有了这个初始化，就出现了一条大实线。

 const bigSlider = new Swiper('.big-slider',{
        spaceBetween: 10,
        autoplay: {
            delay: 4000
        },
        loop: true,
        pagination: {
            el: '.swiper-pagination',
            type: 'progressbar',
        },
        
    })

    使用子弹自定义和 SVG的选项

    const swiper = new Swiper('.swiper', {
  loop: true,
  autoplay: {
    delay: 5000,
    disableOnInteraction: false
  },
  pagination: {
    el: '.swiper-pagination',
    bulletClass: 'swiper-pagination-bullet-custom',
    bulletActiveClass: 'swiper-pagination-bullet-custom--active',
    renderBullet: function(index, className) {
      return `<div class="${className}" data-index="${index}">
        <svg viewbox="0 0 20 20">
            <circle r="9" cx="10" cy="10" fill="none" stroke-width="1.5" stroke="#fff"/>
        </svg>
      </div>`
    },
    clickable: true
  },
  navigation: {
    nextEl: '.swiper-button-next',
    prevEl: '.swiper-button-prev',
  },
  on: {
    init: function() {
      const _self = this;
      
      _self.el.style.setProperty('--delay', _self.params.autoplay.delay);
      
      _self.el.addEventListener('mouseenter', function() {
        _self.el.classList.add('swiper--pause');
        _self.autoplay.stop();
      });

      _self.el.addEventListener('mouseleave', function() {
        _self.el.classList.remove('swiper--pause');
        _self.autoplay.start();
      });
    }
  }
});

<!-- Slider main container -->
<div class="swiper">
  <!-- Additional required wrapper -->
  <div class="swiper-wrapper">
    <!-- Slides -->
    <div class="swiper-slide">
      <div class="swiper-slide-wrap">Slide 1</div>
    </div>
    <div class="swiper-slide">
      <div class="swiper-slide-wrap">Slide 2</div>

    <div class="swiper-slide">
      <div class="swiper-slide-wrap">Slide 3</div>

    <div class="swiper-slide">
      <div class="swiper-slide-wrap">Slide 4</div>
    </div>
    <div class="swiper-slide">
      <div class="swiper-slide-wrap">Slide 5</div>
    </div>
  </div>
  <!-- If we need pagination -->
  <div class="swiper-pagination"></div>

  <!-- If we need navigation buttons -->
  <div class="swiper-button-prev"></div>
  <div class="swiper-button-next"></div>
</div>

    Ps JS 中
    的值必须与CSS中的y匹配。delayanimation-duration.swiper-pagination-bullet-custom--active svg circle

    v0.1 - 添加了停止滑动自动切换计时器的功能，同时“预加载器”动画被重置。
    另外，现在您不需要自己添加到 CSSanimation-duration中，它会在使用 CSS 变量初始化滑块时添加。
