获取在Puppeteer中悬停的链接的href

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  await page.goto('https://example.com');

  // 假设我们要悬停的链接的选择器是 'a.target-link'
  const selector = 'a.target-link';

  // 悬停在链接上
  await page.hover(selector);

  // 获取悬停链接的 href 属性
  const href = await page.evaluate((sel) => {
    const element = document.querySelector(sel);
    return element ? element.getAttribute('href') : null;
  }, selector);

  console.log('悬停链接的 href:', href);

  await browser.close();
})();

await page.waitForSelector(selector);

const href = await page.evaluate((sel) => {
  const element = document.querySelector(sel);
  if (element && element.hasAttribute('href')) {
    return element.getAttribute('href');
  }
  return null;
}, selector);
