Playwright Python: Click Specific from Multiple Button

You can not interact with extensions in playwright. You could script windows tasks like clicking, waiting, pressing keys etc and run it with headfull browser mode.

I have the same problem. As David said, this error means that python-playwright or selenium is not launching correctly. What I did is

Check the version of your chrome Right upper corner -> help -> About Google Chrome
Download the chromedriver from chromedriver!
let your API find the driver

api = TikTokApi.get_instance(use_selenium=True, executablePath="/path/to/chromedriver")

afaik, playwright uses a virtual keyboard and does not exactly send the same signal as a real keyboard to the browser application.

consider going native and using something closer to kernel like pyautogui, after you've focused you window:

import pyautogui
pyautogui.press('f5')

https://stackoverflow.com/questions/74260772/how-to-type-f5-to-refresh-a-page-using-playwright-python

The accepted answer does not work with the newer versions of Playwright. (Thanks @576i for pointing this out)

Here is the Python code that works with the newer versions (tested with version 1.5):

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch()
    page = browser.new_page()
    page.goto('http://whatsmyuseragent.org/')
    ua = page.query_selector(".user-agent");
    print(ua.inner_html())
    browser.close()

To get only the text, use the inner_text() function.

print(ua.inner_text())

The following is one way to get the images on that page - apparently only 398, not 600+ - it's even specified in the top breadcrumb - Trail Running Shoes(398)). Solution is based on Selenium, you're welcome to functionalize it, OOP it, whatever, I'm only giving you the actual method of obtaining the images.

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
import time as t

chrome_options = Options()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument('disable-notifications')
chrome_options.add_argument("--headless")
chrome_options.add_argument("window-size=1280,1080")

webdriver_service = Service("chromedriver/chromedriver") ## path to where you saved chromedriver binary
browser = webdriver.Chrome(service=webdriver_service, options=chrome_options)
wait = WebDriverWait(browser, 20)
actions = ActionChains(browser)


url = 'https://www.tradeinn.com/runnerinn/en/mens-shoes-trail-running-shoes/10005/s#fq=id_familia=10002&sort=v30_sum;desc@tm10;asc&fe=&pf=id_subfamilia=10005@&start=0'
browser.get(url)
pbody = wait.until(EC.presence_of_element_located((By.TAG_NAME, 'body')))
for x in range(14):
    pbody.send_keys(Keys.PAGE_DOWN)
    print('scrolled')
    t.sleep(1)
t.sleep(5)
images = wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, 'img[class="imagen_buscador"]')))
print(len(images))
for i in images:
    print(i.get_attribute('src'))

Result in terminal:

Type F12 in Google Chrome and go to the console.

Write $x() and place the xpath selector inside the parenthesis. Hit the enter key and make sure you actually find the right selector.

No need to use e.value, you can do something like this:

p1 = page.locator("//*[@id='rc-tabs-1-panel-apikey']/div/span/input")
p1text = p1.inner_text

Also - use * as less as possible. If the element with the id is a div write div for example and not *. It makes the searching faster.

https://stackoverflow.com/questions/68440957/playwright-impl-api-types-error-error-failed-to-find-element-matching-select

Try with:

await page.locator('//input[@value="Submit"]').click();

await page.locator('//input[@type="submit"]').click();

await page.locator('//input[@name="Submit1"]').click();

Then you are trying with Xpath, which should be enough if that is the only submit value/name/type of the page.

Basically with .locator you are locating the element and then with .click() you are making click on that element previously located

Fully working example

from playwright.sync_api import sync_playwright
import time

def run(playwright):
    chrome = playwright.chromium
    browser = chrome.launch(headless=False)
    context = browser.new_context()
    page = context.new_page()
    page.goto("https://suip.biz/?act=iscloudflare")
    page.locator("//input[@name='url']").fill("google.com")
    page.locator("//input[@value='Submit']").click()
    time.sleep(10)
    browser.close()

with sync_playwright() as playwright:
    run(playwright)

How To Run Your First Playwright Test On Cloud

One of the biggest problems I’ve faced when building a test suite is not the writing of the tests but the execution. How can I execute 100s or 1000s of tests in parallel?If I try that on my local machine, it would probably catch fire – so we need a remote environment to send these to.
