Puppeteer: How to submit a form?

Using puppeteer, how could you programmatically submit a form? So far I've been able to do this using

page.click('.input[type="submit"]')
if the form actually includes a submit input. But for forms that don't include a submit input, focusing on the form text input element and using
page.press('Enter')
doesn't seem to actually cause the form to 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 into the search bar
await page.focus('.js-search-field');
await page.type('puppeteer');

// Submit form
await page.press('Enter');

// Wait for search results page to load
await page.waitForNavigation({waitUntil: 'load'});


console.log('FOUND!', page.url());

// Extract the results from the 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());
