如何限制显示的子弹数量 swiperjs

Question

是否可以在 swiperjs 中使其始终显示 5 个相同大小的分页按钮。切换时，如果幻灯片超过 5 张，则第一个按钮消失，最后一个按钮出现（按钮 6）。 DynamicBullets behavior: true, 加上自定义分页很奇怪。或者也许还有其他一些现成的滑块有类似的东西。我寻求帮助

window.addEventListener('load', function() {

var menu = ['1989', '1990', '1991', '1992', '1993', '1994','1995']
var mySwiper = new Swiper ('.swiper-container', {
    // If we need pagination
    pagination: {
      el: '.swiper-pagination',
      clickable: true,
      dynamicBullets: true,
        renderBullet: function (index, className) {
          return '<span class="' + className + '">' + (menu[index]) + '</span>';
        },
    },

    // Navigation arrows
    navigation: {
      nextEl: '.swiper-button-next',
      prevEl: '.swiper-button-prev',
    },
  })
})

.swiper-container {
    width: 100%;
    height: 500px;
}
.swiper-slide {
    text-align: center;
    font-size: 18px;
    background: #fff;
    /* Center slide text vertically */
    display: -webkit-box;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    -webkit-box-pack: center;
    -ms-flex-pack: center;
    -webkit-justify-content: center;
    justify-content: center;
    -webkit-box-align: center;
    -ms-flex-align: center;
    -webkit-align-items: center;
    align-items: center;
}
.swiper-pagination {
    position: absolute;
    top: 10px;
    right: 10px;
    width: auto !important;
    left: auto !important;
    margin: 0;
}
.swiper-pagination-bullet {
    padding: 5px 10px!important;
    border-radius: 0!important;
    width: auto!important;
    height: 30px!important;
    text-align: center!important;
    line-height: 30px!important;

    color:#000!important;
    opacity: 1!important;

}
.swiper-pagination-bullet-active {
    color:#fff!important;
    background: #007aff!important;

添加这些行：

动态子弹：真，

dynamicMainBullets：4

var swiper = new Swiper ('.swiper-container', {
    direction: 'horizontal',
    observer: true,
    observeParents: true,
    slidesPerView: 1,
    centeredSlides: false,
    spaceBetween: 10,
        pagination: {
            el: ".swiper-pagination",
            dynamicBullets: true,
            dynamicMainBullets: 4
    }
}
