Puppeteer: How to submit a form?

Question

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();

})();

Solution 1

If you are attempting to fill out and submit a login form, you can use the following:

await page.goto('https://www.example.com/login');

await page.type('#username', 'username');
await page.type('#password', 'password');

await page.click('#submit');

await page.waitForNavigation();

console.log('New Page URL:', page.url());

Solution 2

Try this

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

---

For v0.11.0 and laters:

await page.$eval('form-selector', form => form.submit());

Thanks! Looks like the issue was not using .evaluate() on the form element - didn't know you could do that.

@NamMaiAnh i am getting TypeError: form.evaluate is not a function

[Nam Mai Anh]

@redochka May you show me the code? Have you determined if form was null or not?

[realappie]

@NamMaiAnh 'ElementHandle' do not have the 'evaluate' method.

@Abdel I have updated the answer for v0.11.0 and laters. Thank you!

await page.evaluate(form => form.submit(), form); is the correct syntax.

Also, it fails when you use just await page.type('puppeteer'); but add this to the selection await page.type('.js-search-field', 'puppeteer');

Keep in mind that if the inputs already have content like in the case of updating a form, this method will prepend the data already in the input field.

@mckenna "Another interesting solution is to click the target field 3 times so that the browser would select all the text in it and then you could just type what you want:" await input.click({ clickCount: 3 }) : stackoverflow.com/a/52633235/556169
