I try to scrape product titles from https://www.ternbicycles.com/us/bikes#
I try to use xpath and css selector, but the find_elements() function only returns empty list. I didn't find framesets from this page and use execute_script to scrolled the window down to bottom... oh and I did set up wait time
But still no use....
Could some one help me out. Maybe could help me to try this url and give me some idea Thank you
URL='https://www.ternbicycles.com/us/bikes'
driver.implicitly_wait(10)
driver.get(URL)
driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
print(driver.title)
titles=driver.find_elements(By.CSS_SELECTOR,"//a[normalize-space()='Quick Haul P9 Performance']")
print(titles)
#result: Just a moment... []

i am using colab and i got TimeoutException: Message: Stacktrace... think should be a configuration problem? Do you have any solution?
Here is what i imported before i ran your codes
!apt-get update
!apt install chromium-chromedriver
!cp /usr/lib/chromium-browser/chromedriver /usr/bin
!pip install selenium
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait
#set up Chrome driver
options=webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
options.add_argument("window-size=1280,720")
#Define web driver as a Chrome driver
driver=webdriver.Chrome('chromedriver',options=options)
driver.implicitly_wait(10)

The webpage isn't dynamic. So you can parse all the required contents/data with the help of bs4 and requests module.
Example:
import requests
from bs4 import BeautifulSoup
import pandas as pd
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0'}
r = requests.get('https://www.ternbicycles.com/us/bikes',headers =headers)
print(r)
soup = BeautifulSoup(r.text,'html.parser')
for card in soup.select('div[] > div'):
title = card.select_one('h2[] > a').get_text(strip=True)
print(title)
Output:

The following selenium based solution works (tested):
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
chrome_options = Options()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument('disable-notifications')
chrome_options.add_argument("window-size=1280,720")
webdriver_service = Service("chromedriver/chromedriver") ## path to where you saved chromedriver binary
browser = webdriver.Chrome(service=webdriver_service, options=chrome_options)
url = 'https://www.ternbicycles.com/us/bikes'
browser.get(url)
try:
WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, ".agree-button.eu-cookie-compliance-agree-button"))).click()
print('accepted cookies')
except Exception as e:
print('no cookies for you')
browser.execute_script("window.scrollTo(0,document.body.scrollHeight);")
bikes = WebDriverWait(browser, 20).until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, "h2[class='font-header-bold pb-4']")))
for b in bikes:
print(b.text)
This will print out:
accepted cookies

Selenium setup is for python, you can adapt the code to your own setup, just note the imports and the code after defining the browser (driver). Selenium docs: https://www.selenium.dev/documentation/

To extract the name of the product titles you have to induce WebDriverWait for visibility_of_all_elements_located() and using List Comprehension you can use either of the following locator strategies:
Using CSS_SELECTOR and text attribute:
driver.get('https://www.ternbicycles.com/us/bikes#') WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.agree-button.eu-cookie-compliance-agree-button"))).click() print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div.title>h2>a")))])Using XPATH and
get_attribute("innerHTML"):driver.get('https://www.ternbicycles.com/us/bikes#') WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[@class='agree-button eu-cookie-compliance-agree-button']"))).click() print([my_elem.get_attribute("innerHTML") for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='title']/h2/a")))])Console Output:
