js 长文章分页

const articleContent = "<p>这里是文章内容...</p>"; // 假设这是一个很长的字符串
const itemsPerPage = 10;  // 每页显示的段落数量
let currentPage = 1;  // 当前页码

function paginateArticle(content, itemsPerPage) {
  const paragraphs = content.split('</p>');  // 简单按照段落分割
  const totalPages = Math.ceil(paragraphs.length / itemsPerPage);
  return {
    totalPages,
    currentPage: 1,
    pages: []
  };
}

const paginatedArticle = paginateArticle(articleContent, itemsPerPage);

function displayPage(pageNumber) {
  const start = (pageNumber - 1) * itemsPerPage;
  const end = start + itemsPerPage;
  const pageContent = paragraphs.slice(start, end).join('</p>') + '</p>';
  document.getElementById('article-container').innerHTML = pageContent;
}

displayPage(currentPage);
