I've written a script in python to scrape names from a slow loading webpage. There are 1000 names in that page and the full content can only be loaded when the browser is made to scroll downmost. However, my script can successfully reach the lowest portion of this page and parse all the names. The issue I'm facing here is that I've used hardcoded delay which is 5 seconds in this case and it makes the browser unnecessarily wait even when the item is loaded. So how can i use explicit wait to overcome this situation and parse all the item.
Here is the script I've written so far:
from selenium import webdriver
import time
driver = webdriver.Chrome()
driver.get("http://fortune.com/fortune500/list/")
check_height = driver.execute_script("return document.body.scrollHeight;")
while True:
driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
time.sleep(5)
height = driver.execute_script("return document.body.scrollHeight;")
if height == check_height:
break
check_height = height
listElements = driver.find_elements_by_css_selector(".company-title")
for item in listElements:
print(item.text)
You can add Explicit wait as below:
from selenium.webdriver.support.ui import WebDriverWait
from selenium import webdriver
driver = webdriver.Chrome()
driver.get("http://fortune.com/fortune500/list/")
check_height = driver.execute_script("return document.body.scrollHeight;")
while True:
driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
try:
WebDriverWait(driver, 10).until(lambda driver: driver.execute_script("return document.body.scrollHeight;") > check_height)
check_height = driver.execute_script("return document.body.scrollHeight;")
except:
break
listElements = driver.find_elements_by_css_selector(".company-title")
for item in listElements:
print(item.text)
This should allow you to avoid hardcoding time.sleep()- instead you're just waiting for changing height value or break the loop in case height is constant after 10 seconds passed after scrolling...
You need to use explicit waits, like this:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Firefox()
driver.get("http://somedomain/url_that_delays_loading")
try:
element = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.ID, "myDynamicElement"))
)
finally:
driver.quit()

I want to click on each product on aliexpress and do something with it.
However, I kept running into an ElementClickInterceptedException
Please verify that the code is correct before answering the question if you are using chat-GPT or any other AI to help with this problem.
These are the things that I tried
for supplier in suppliers:
driver.execute_script("arguments[0].scrollIntoView();", supplier)
actions = ActionChains(driver)
actions.move_to_element(supplier).click().perform()
for supplier in suppliers:
driver.execute_script("arguments[0].scrollIntoView();", supplier)
actions = ActionChains(driver)
actions.move_to_element(supplier)
wait.until(EC.visibility_of_element_located((By.XPATH, ".//*[#class='list--gallery--34TropR']//span/a")))
try:
supplier.click()
except ElementClickInterceptedException:
print('object not on screen')
However, this still gives me the highest click-through-rate
for supplier in suppliers:
try:
supplier.click()
print('Supplier clicked')
time.sleep(1)
except ElementClickInterceptedException:
print('object not on screen')
This is how I initialized the driver and loaded the elements.
search_key = "Motor+toy+boat"
suppliers = []
print("https://www.aliexpress.com/premium/"+search_key+".html?spm=a2g0o.best.1000002.0&initiative_id=SB_20221218233848&dida=y")
# create a webdriver object and set the path to the Chrome driver
service = Service('../venv/chromedriver.exe')
driver = webdriver.Chrome(service=service)
# navigate to the Aliexpress website
driver.get("https://www.aliexpress.com/")
# Wait for the page to load
wait = WebDriverWait(driver, 10)
wait.until(EC.presence_of_element_located((By.ID, "search-key")))
# wait for the page to load
driver.implicitly_wait(10)
driver.get("https://www.aliexpress.com/premium/"+search_key+".html?spm=a2g0o.best.1000002.0&initiative_id=SB_20221218233848&dida=y")
last_height = driver.execute_script("return document.body.scrollHeight")
while True:
driver.execute_script("window.scrollBy(0, 800);")
sleep(1)
new_height = driver.execute_script("return document.body.scrollHeight")
if new_height == last_height:
print(new_height, last_height)
break
last_height = new_height
for element in driver.find_elements(By.XPATH, "//*[contains(#class, 'manhattan--container--1lP57Ag cards--gallery--2o6yJVt')]"):
suppliers.append(element)
Couple of issues I have identified.
It is detecting bot, so after couple of runs it will stop identifying the element.Use --disable-blink-features in chrome options.
Once you iterate the list,it is clicking somewhere else, just wait for a second and then click, it will work.
added code will click only visible element on the page, If you need to click more you needed to scroll the page and then click.
You can check the count of total visible element on the page.

I'm trying to scrape a website (https://harleytherapy.com/therapists?page=1) that looks like it's been generated by Javascript and the element I'm trying to scrape (the lu with id="downshift-7-menu") doesn't appear on the "Page source" but only after I click on "Inspect element".
I tried to find a solution here and so far this the code I was able to come up with (a combination of Selenium + Beautiful soup)
import requests
from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
import time
url = "https://harleytherapy.com/therapists?page=1"
options = webdriver.ChromeOptions()
options.add_argument('headless')
capa = DesiredCapabilities.CHROME
capa["pageLoadStrategy"] = "none"
driver = webdriver.Chrome(chrome_options=options, desired_capabilities=capa)
driver.set_window_size(1440,900)
driver.get(url)
time.sleep(15)
plain_text = driver.page_source
soup = BeautifulSoup(plain_text, 'html')
therapist_menu_id = "downshift-7-menu"
print(soup.find(id=therapist_menu_id))
I thought that allowing Selenium to wait for 15 seconds would make sure that all elements are loaded but I still can't find any element with id downshift-7-menu in the soup. Do you guys know what's wrong with my code?
The element with ID downshift-7-menu is loaded only after opening the THERAPIST dropdown menu, you can do it by scrolling it into view to load it and then clicking on it. You should also consider replacing sleep with explicit wait
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
wait = WebDriverWait(driver, 15)
# scroll the dropdown into view to load it
side_menu = wait.until(EC.visibility_of_element_located((By.CLASS_NAME, 'inner-a377b5')))
last_height = driver.execute_script("return arguments[0].scrollHeight", side_menu)
while True:
driver.execute_script("arguments[0].scrollTo(0, arguments[0].scrollHeight);", side_menu)
new_height = driver.execute_script("return arguments[0].scrollHeight", side_menu)
if new_height == last_height:
break
last_height = new_height
# open the menu
wait.until(EC.visibility_of_element_located((By.ID, 'downshift-7-input'))).click()
# wait for the option to load
therapist_menu_id = 'downshift-7-menu'
wait.until(EC.presence_of_element_located((By.ID, therapist_menu_id)))
print(soup.find(id=therapist_menu_id))

Some help, thanks
The Reason being you are getting timeout is as your page is infinite loading page i.e. new elements are getting loaded if you go to bottom of page. Now even if few elements are there in DOM, they are not being located by selenium, As a result you are getting time out. Try to first load all elements and then locate them.
driver.get('https://www.unibet.fr/sport/football')
WebDriverWait(driver, 60).until(EC.presence_of_element_located((By.XPATH, '//a[#data-track-action="start_page"]'))) #Wait for page to load
#Scroll till page is loaded completely
last_height = driver.execute_script("return document.body.scrollHeight")
while True:
# Scroll down to bottom
driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
# Wait to load page
time.sleep(2)
# Calculate new scroll height and compare with last scroll height
new_height = driver.execute_script("return document.body.scrollHeight")
if new_height == last_height:
break
last_height = new_height
#Get the elements
odds = [my_elem.text for my_elem in driver.find_elements_by_xpath( '//span[contains(#class, "ui-touchlink-needsclick price odd-price")]')]
print(odds, '\n')
driver.close()
driver.quit()
Out Put:
I have following code to scroll down a javascript enabled website. Problem is when the newHeight reaches around 229275 I get list out of range on the line browser.find_elements_by_class_name('alt')[0].click(). But why I am getting this error and how can I solve this?
My code:
browser = webdriver.PhantomJS("phantomjs")
browser.get(url)
while True:
time.sleep(pause)
newHeight = browser.execute_script("return document.body.scrollHeight")
print newHeight
browser.find_elements_by_class_name('alt')[0].click()
Try to scroll down page and click element with below approach:
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait as wait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import NoSuchElementException
browser = webdriver.PhantomJS("phantomjs")
browser.get(url)
while True:
browser.find_element_by_tag_name("body").send_keys(Keys.END)
try:
wait(browser, 10).until(EC.element_to_be_clickable((By.CLASS_NAME, "alt"))).click()
except NoSuchElementException:
break
This should allow you to click required element in case it can be found or break loop otherwise
Simply try/except statement
browser = webdriver.PhantomJS("phantomjs")
browser.get(url)
while True:
try:
time.sleep(pause)
newHeight = browser.execute_script("return document.body.scrollHeight")
print newHeight
browser.find_elements_by_class_name('alt')[0].click()
except:
pass
I would recommend checking the list before acting upon it.
browser = webdriver.PhantomJS("phantomjs")
browser.get(url)
while True:
time.sleep(pause)
newHeight = browser.execute_script("return document.body.scrollHeight")
print newHeight
alt_elements = browser.find_elements_by_class_name('alt')
if len(alt_elements):
alt_elements[0].click()
Just a side note, an infinite while loop can be a dangerous thing.
