Click on “Show more deals” in webpage with Seleniu

问题:

I'd like to click on every 'Show 10 more deals' on the following page: "https://www.uswitch.com/broadband/compare/deals_and_offers/" but it does not seem to work. I'm stuck having the following error:

 AttributeError: 'NoneType' object has no attribute 'find_element'

My code is the following:

from selenium import webdriver
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

url = "https://www.uswitch.com/broadband/compare/deals_and_offers/"

driver = webdriver.Chrome(r'C:\temp\chromedriver.exe')

browser = driver.get(url)
while True:
    button = WebDriverWait(browser,10).until(EC.presence_of_element_located((By.PARTIAL_LINK_TEXT, 'Show 10 more deals')))
button.click()

Any idea?

To click on the element with text as Show 10 more deals on the page https://www.uswitch.com/broadband/compare/deals_and_offers/ you can use the following solution:

• Code Block:

  from selenium import webdriver
  from selenium.webdriver.support.wait import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  from selenium.webdriver.common.by import By
  
  url = "https://www.uswitch.com/broadband/compare/deals_and_offers/"
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_argument('disable-infobars')
  browser = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  browser.get(url)
  while True:
      try:
          browser.execute_script("return arguments[0].scrollIntoView(true);", WebDriverWait(browser,20).until(EC.visibility_of_element_located((By.XPATH, "//button[@class='us-btn us-btn--action' and contains(.,'Show 10 more deals')]"))))
          browser.execute_script("arguments[0].click();", WebDriverWait(browser,20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.us-btn.us-btn--action[name='visible_products']"))))
          print("Button clicked")
      except:
          print("No more Buttons")
          break
  browser.quit()
  

• Console Output:

  Button clicked
  Button clicked
  Button clicked
  Button clicked
  Button clicked
  Button clicked
  Button clicked
  Button clicked
  Button clicked
  Button clicked
  No more Buttons

Try the following which uses a CSS attribute = value selector to target the data-event-action attribute of the button by its value

driver.find_element_by_css_selector('[data-event-action="Show 10 more products"]').click()

Replace driver with browser if required.

Try it like this:

while not re.search(r"Showing (\d+) of \1 ", browser.page_source):
  browser.execute_script("document.querySelector('[data-event-label=\"Show 10 more products\"]').click()")
  time.sleep(1)

This avoids the selenium errors that will eventually drive you nuts.
