Puppeteer: 鼠标移动

mouse.click 是 mouse.move，mouse.down 和 mouse.up 的快捷方式

main.js

const pptr = require('puppeteer');

const gotoUrl = 'http://127.0.0.1:5500/index.html';

(async () => {

  const browser = await pptr.launch({

    headless: false,

    slowMo: 250,

  });

  const page = await browser.newPage();

  page.on('console', msg => {

    console.log(msg.text());

  });

  await page.goto(gotoUrl);

  await page.mouse.move(100, 100);

  await page.mouse.down();

  await page.mouse.move(200, 100, {

    steps: 3,

  });

  await page.mouse.move(200, 200);

  await page.mouse.move(100, 200);

  await page.mouse.move(100, 100);

  await page.mouse.up();

  await page.mouse.move(150, 150);

  await page.mouse.down();

  setTimeout(async () => {

    await browser.close();

  }, 2000);

})();
