如何在puppeteer中检查元素中是否包含某个字符串？

const puppeteer = require('puppeteer');

async function checkElementContainsString() {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');

  const elementSelector = 'h1'; // 选择要检查的元素的CSS选择器
  const searchString = 'example'; // 要检查的字符串

  const isStringContained = await page.evaluate((selector, search) => {
    const element = document.querySelector(selector);
    return element.textContent.includes(search);
  }, elementSelector, searchString);

  console.log(`The element contains the string: ${isStringContained}`);

  await browser.close();
}

checkElementContainsString();
