如何使用amaze ui的分页样式封装一个通用的JS分页控件

<ul data-am-widget="pagination"
      class="am-pagination am-pagination-default"
      >

      <li class="am-pagination-first ">
        <a href="#" class="">第一页</a>
      </li>

      <li class="am-pagination-prev ">
        <a href="#" class="">上一页</a>
      </li>
            <li class="">
              <a href="#" class="">1</a>
            </li>
            <li class="am-active">
              <a href="#" class="am-active">2</a>
            </li>
            <li class="">
              <a href="#" class="">3</a>
            </li>
            <li class="">
              <a href="#" class="">4</a>
            </li>
            <li class="">
              <a href="#" class="">5</a>
            </li>


      <li class="am-pagination-next ">
        <a href="#" class="">下一页</a>
      </li>

      <li class="am-pagination-last ">
        <a href="#" class="">最末页</a>
      </li>
  </ul>
