Cnki Navigate Pages

CNKI 结果翻页与排序

在当前知网检索结果页执行翻页或排序操作。操作后通常继续使用 $cnki-parse-results 读取新页面结果。

Codex 工具约定

• 使用 Codex Browser/in-app browser 或等价浏览器自动化工具在当前页面执行 JavaScript。
• 不需要重新导航，除非当前页不是知网结果页。
• 遇到验证码时暂停，让用户在浏览器中手动完成。

输入

从用户请求中识别：

• 翻页：next、previous、page N、第 N 页。
• 排序：发表时间、被引、下载、相关度、综合。

翻页脚本

把 ACTION_HERE 替换为 "next"、"previous" 或 "page 3"。

async () => {
  const captcha = document.querySelector('#tcaptcha_transform_dy');
  if (captcha && captcha.getBoundingClientRect().top >= 0) return { error: 'captcha' };

  const action = "ACTION_HERE";
  const pageLinks = document.querySelectorAll('.pages a');
  const previousPageMark = document.querySelector('.countPageMark')?.innerText;

  if (action === 'next') {
    const next = Array.from(pageLinks).find((a) => a.innerText.trim() === '下一页');
    if (!next) return { error: 'no_next_page' };
    next.click();
  } else if (action === 'previous') {
    const previous = Array.from(pageLinks).find((a) => a.innerText.trim() === '上一页');
    if (!previous) return { error: 'no_previous_page' };
    previous.click();
  } else {
    const pageNumber = action.replace(/\D/g, '');
    const target = Array.from(pageLinks).find((a) => a.innerText.trim() === pageNumber);
    if (!target) {
      return {
        error: 'page_not_found',
        available: Array.from(pageLinks).map((a) => a.innerText.trim()).filter(Boolean)
      };
    }
    target.click();
  }

  await new Promise((resolve, reject) => {
    let tries = 0;
    const check = () => {
      const currentPageMark = document.querySelector('.countPageMark')?.innerText;
      if (currentPageMark && currentPageMark !== previousPageMark) resolve();
      else if (++tries > 30) reject(new Error('timeout: page change'));
      else setTimeout(check, 500);
    };
    setTimeout(check, 1000);
  });

  const captchaAfterAction = document.querySelector('#tcaptcha_transform_dy');
  if (captchaAfterAction && captchaAfterAction.getBoundingClientRect().top >= 0) return { error: 'captcha' };

  return {
    action,
    total: document.querySelector('.pagerTitleCell')?.innerText?.match(/([\d,]+)/)?.[1] || '0',
    page: document.querySelector('.countPageMark')?.innerText || '?',
    url: location.href
  };
}

排序脚本

把 SORT_HERE 替换为 "relevance"、"date"、"citations"、"downloads" 或 "comprehensive"。

async () => {
  const captcha = document.querySelector('#tcaptcha_transform_dy');
  if (captcha && captcha.getBoundingClientRect().top >= 0) return { error: 'captcha' };

  const sortBy = "SORT_HERE";
  const idMap = {
    relevance: 'FFD',
    date: 'PT',
    citations: 'CF',
    downloads: 'DFR',
    comprehensive: 'ZH'
  };

  const liId = idMap[sortBy];
  if (!liId) return { error: 'invalid_sort', valid: Object.keys(idMap) };

  const option = document.querySelector('#orderList li#' + liId);
  if (!option) return { error: 'sort_option_not_found' };

  const previousPageMark = document.querySelector('.countPageMark')?.innerText;
  option.click();

  await new Promise((resolve, reject) => {
    let tries = 0;
    const check = () => {
      const currentPageMark = document.querySelector('.countPageMark')?.innerText;
      if (currentPageMark && currentPageMark !== previousPageMark) resolve();
      else if (++tries > 30) reject(new Error('timeout: sort'));
      else setTimeout(check, 500);
    };
    setTimeout(check, 1000);
  });

  return {
    sortBy,
    total: document.querySelector('.pagerTitleCell')?.innerText?.match(/([\d,]+)/)?.[1] || '0',
    page: document.querySelector('.countPageMark')?.innerText || '?',
    activeSort: document.querySelector('#orderList li.cur')?.innerText?.trim(),
    url: location.href
  };
}

汇报

已切换：{action 或 sortBy}
当前页：{page}，总结果：{total}。
