javascript - Puppeteer: How to submit a form? -

using puppeteer, how programmatically submit form? far i've been able using page.click('.input[type="submit"]') if form includes submit input. forms don't include submit input, focusing on form text input element , using page.press('enter') doesn't seem cause form submit:

const puppeteer = require('puppeteer');  (async() => {      const browser = await puppeteer.launch();     const page = await browser.newpage();     await page.goto('https://stackoverflow.com/', {waituntil: 'load'});     console.log(page.url());      // type our query search bar     await page.focus('.js-search-field');     await page.type('puppeteer');      // submit form     await page.press('enter');      // wait search results page load     await page.waitfornavigation({waituntil: 'load'});       console.log('found!', page.url());      // extract results page     const links = await page.evaluate(() => {       const anchors = array.from(document.queryselectorall('.result-link a'));       return anchors.map(anchor => anchor.textcontent);     });     console.log(links.join('\n'));     browser.close();  })(); 

try this

const form = await page.$('form-selector'); await form.evaluate(form => form.submit());
