CNKI Journal Search (期刊检索)

RC browser tool: navigate with browser action=open url="..."; run the JS in each step via browser action=act kind=evaluate fn="<the async function shown>" (the whole function body goes into fn). Never pass a profile — RC uses its default managed Chrome (CDP 18800).

Arguments

$ARGUMENTS is a journal name, ISSN, CN number, or sponsor name.

Steps

1. Navigate

Use browser action=open → https://navi.cnki.net/knavi

2. Search + extract results (single browser act kind=evaluate, NO wait_for)

Use browser action=act kind=evaluate. Replace QUERY_HERE with actual search term:

async () => {
  const query = "QUERY_HERE";

  // Wait for page load
  await new Promise((r, j) => {
    let n = 0;
    const c = () => { if (document.querySelector('input.researchbtn')) r(); else if (++n > 30) j('timeout'); else setTimeout(c, 500); };
    c();
  });

  // Check captcha (visible on screen, not hidden SDK at top:-1000000)
  const outer = document.querySelector('#tcaptcha_transform_dy');
  if (outer && outer.getBoundingClientRect().top >= 0) return { error: 'captcha' };

  // Auto-detect search type and fill
  const select = document.querySelector('select');
  if (select) {
    if (/^\d{4}-\d{3}[\dXx]$/.test(query)) select.value = 'ISSN';
    else if (/^\d{2}-\d{4}/.test(query)) select.value = 'CN';
    select.dispatchEvent(new Event('change', { bubbles: true }));
  }

  const input = document.querySelector('input[placeholder*="检索词"]');
  if (input) input.value = query;

  // Click search button (verified selector: input.researchbtn)
  document.querySelector('input.researchbtn')?.click();

  // Wait for results
  await new Promise((r, j) => {
    let n = 0;
    const c = () => { if (document.body.innerText.includes('条结果')) r(); else if (++n > 30) j('timeout'); else setTimeout(c, 500); };
    c();
  });

  // Click 期刊 tab to filter journals only
  const tabs = document.querySelectorAll('li a');
  for (const a of tabs) { if (a.innerText.trim() === '期刊') { a.click(); break; } }
  await new Promise(r => setTimeout(r, 1500));

  // Extract journal results
  const body = document.body.innerText;
  const countMatch = body.match(/共\s*(\d+)\s*条结果/) || body.match(/找到\s*(\d+)\s*条结果/);
  const count = countMatch ? parseInt(countMatch[1]) : 0;

  const results = [];
  const titleLinks = document.querySelectorAll('a[href*="knavi/detail"]');
  titleLinks.forEach(link => {
    const text = link.innerText?.trim();
    if (!text || text.length < 2) return;
    // Link markup: textNode(中文名) + <i>EN name</i> + <span class="flag">网络首发</span>.
    // Take the CN name from the first text node so EN name and flag tags don't leak in.
    const cnNode = Array.from(link.childNodes).find(n => n.nodeType === 3 && n.textContent.trim());
    const name = (cnNode ? cnNode.textContent : text.split('\n')[0]).trim();
    const nameEN = link.querySelector('i')?.innerText?.trim() || '';
    const parent = link.closest('li, .list-item') || link.parentElement?.parentElement;
    const pt = parent?.innerText || '';
    results.push({
      name,
      nameEN,
      url: link.href,
      issn: pt.match(/ISSN[：:]\s*(\S+)/)?.[1] || '',
      cn: pt.match(/CN[：:]\s*(\S+)/)?.[1] || '',
      cif: pt.match(/复合影响因子[：:]\s*([\d.]+)/)?.[1] || '',
      aif: pt.match(/综合影响因子[：:]\s*([\d.]+)/)?.[1] || '',
      citations: pt.match(/被引次数[：:]\s*([\d,]+)/)?.[1] || '',
      downloads: pt.match(/下载次数[：:]\s*([\d,]+)/)?.[1] || '',
      sponsor: pt.match(/主办单位[：:]\s*(.+?)(?=\n|ISSN)/)?.[1]?.trim() || ''
    });
  });

  return { query, count, results };
}

3. Present results

期刊检索 "$ARGUMENTS"（共 {count} 条）：

1. {name}
   ISSN: {issn} | CN: {cn}
   复合影响因子: {cif} | 综合影响因子: {aif}
   被引: {citations} | 下载: {downloads}

Notes

• Journal detail pages open in new tab — use browser action=tabs + browser action=focus
• If only 1 journal result, can auto-navigate to detail page for cnki-journal-index
• Search button selector: input.researchbtn (not generic button)

Captcha detection

Check #tcaptchatransformdy element's getBoundingClientRect().top >= 0. Tencent captcha SDK preloads DOM at top: -1000000px (off-screen, not active). Only return error: 'captcha' when top >= 0 (actually visible to user).

Tool calls: 2 (navigate + browser act kind=evaluate)
