更改滑块中的数字格式分页

Question

有一个 Swiper 滑块，现在分页看起来像 1 - 3，我需要像 01 - 03 那样。

这是一个演示

<!-- Slider main container -->
<div class="swiper-container">
    <!-- Additional required wrapper -->
    <div class="swiper-wrapper">
        <!-- Slides -->
        <div class="swiper-slide">Slide 1</div>
        <div class="swiper-slide">Slide 2</div>
        <div class="swiper-slide">Slide 3</div>
    </div>
    <!-- If we need pagination -->
    <div class="swiper-pagination"></div>
</div>

JS

var swiper = new Swiper('.swiper-container', { 
      pagination: {
        el: '.swiper-pagination',
        type: 'fraction',
      },
      navigation: {
        nextEl: '.swiper-button-next',
        prevEl: '.swiper-button-prev',
      },
        direction: 'horizontal',
        loop: true,
        slidesPerView: 1,
        spaceBetween: 0,
        mousewheel: true,
        pagination: {
          el: '.swiper-pagination',
          type: 'fraction',
          clickable: true,

        renderFraction: function (currentClass, totalClass) {
        return '<span class="' + currentClass + '"></span>' + ' <span>-</span> ' + '<span class="' + totalClass + '"></span>'; }
        },

    });

谢谢！

由于其他答案不再有效，因此这是一个结构稍微简化的工作变体，适用于最新的 swiper 版本：

var swiper = new Swiper('.swiper-container', {
    effect: 'fade',
    pagination: {
        el: '.swiper-pagination',
        type: 'fraction',
        formatFractionCurrent: function (number) {
            return ('0' + number).slice(-2);
        },
        formatFractionTotal: function (number) {
            return ('0' + number).slice(-2);
        },
        renderFraction: function (currentClass, totalClass) {
            return '<span class="' + currentClass + '"></span>' +
                   ' - ' +
                   '<span class="' + totalClass + '"></span>';
        }
    },
});

.swiper-container {
    width: 100%;
    height: 100px;
}

.swiper-slide {
    text-align: center;
    font-size: 18px;
    background: #fff;
    background: gray;

    /* 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;
}
