尝试从Puppeteer中的elementHandle获取*所有类

const puppeteer = require('puppeteer');

async function getAllClasses() {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com'); // 替换为你要操作的网页地址

  const elementHandle = await page.$('your-selector'); // 替换为你要获取类的元素选择器

  const classListProperty = await elementHandle.getProperty('classList');
  const classList = await classListProperty.jsonValue();

  const classesArray = Array.from(classList);
  const allClasses = classesArray.join(' ');

  console.log(allClasses);

  await browser.close();
}

getAllClasses();
