(async () => {
    const browser = await puppeteer.launch({
        ignoreHTTPSErrors: true,
        headless: false,
        slowMo: 250,
        timeout: 0
    });
    const page = await browser.newPage();

    await page.setViewport({
        width: 1024,
        height: 980
    })
    await page.goto('https://www.baidu.com/');
    const nm = await page.$("#kw");//通过id获得页面上的控件
    await nm.focus(); //定位到搜索框
    await page.keyboard.type("puppeteer");//模拟输入
    const btn = await page.$("#su");
    btn.click();//模拟按钮单击事件
    // await page.close();
    // await browser.close();
})();
