swiper pagination 渲染不出来

解决办法

<script type="text/javascript">
  var swiper = new Swiper('.swiper-container', {
    pagination: {
      el: '.swiper-pagination',
    },
  });
</script>

换成下面的写法

<script type="text/javascript">
  var swiper = new Swiper('.swiper-container', {
    pagination: '.swiper-pagination',
    paginationClickable: true,
 }); 
</script>
