CNKI Results Pagination and Sorting

All operations use a single async evaluate_script — no snapshot or wait_for needed.

Arguments

$ARGUMENTS should be one of:

• next / previous / page N — pagination
• sort by date / sort by citations / sort by downloads / sort by relevance / sort by comprehensive — sorting

Pagination (single evaluate_script)

Replace ACTION_HERE with "next", "previous", or "page 3":

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

const action = "ACTION_HERE"; const pageLinks = document.querySelectorAll('.pages a'); const prevMark = 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 prev = Array.from(pageLinks).find(a => a.innerText.trim() === '上一页'); if (!prev) return { error: 'no_previous_page' }; prev.click(); } else { const num = action.replace(/\D/g, ''); const target = Array.from(pageLinks).find(a => a.innerText.trim() === num); if (!target) return { error: 'page_not_found', available: Array.from(pageLinks).map(a => a.innerText.trim()) }; target.click(); }

// Wait for page change await new Promise((r, j) => { let n = 0; const c = () => { const mark = document.querySelector('.countPageMark')?.innerText; if (mark && mark !== prevMark) r(); else if (++n > 30) j('timeout'); else setTimeout(c, 500); }; setTimeout(c, 1000); });

const cap2 = document.querySelector('#tcaptcha_transform_dy'); if (cap2 && cap2.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 }; }

## Sorting (single evaluate_script)

Replace `SORT_HERE` with `"relevance"`, `"date"`, `"citations"`, `"downloads"`, or `"comprehensive"`:

```javascript
async () => {
  const cap = document.querySelector('#tcaptcha_transform_dy');
  if (cap && cap.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 li = document.querySelector('#orderList li#' + liId);
  if (!li) return { error: 'sort_option_not_found' };

  const prevMark = document.querySelector('.countPageMark')?.innerText;
  li.click();

  // Wait for results to refresh (page resets to 1)
  await new Promise((r, j) => {
    let n = 0;
    const c = () => {
      const mark = document.querySelector('.countPageMark')?.innerText;
      if (mark && mark !== prevMark) r();
      else if (++n > 30) j('timeout');
      else setTimeout(c, 500);
    };
    setTimeout(c, 1000);
  });

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

Output

Navigated to page {page}. Total {total} results. Results now sorted by {sortBy}.

Tool calls: 1 (evaluate_script only)

Captcha detection

Check #tcaptcha_transform_dy element's getBoundingClientRect().top >= 0. Only active when top >= 0 (visible). Pre-loaded SDK sits at top: -1000000px.
