单击链接在playwright中不起作用

const { chromium } = require('playwright');

(async () => {
  const browser = await chromium.launch();
  const context = await browser.newContext();
  const page = await context.newPage();

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

  // 等待链接加载完成
  await page.waitForSelector('a');

  // 定位到链接元素
  const link = await page.$('a');

  // 检查链接是否可点击
  const isClickable = await link.isClickable();
  if (isClickable) {
    // 单击链接
    await link.click();
  } else {
    console.log('链接不可点击');
  }

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