Playwright vs Selenium
Explore the key differences between Playwright vs Selenium in terms of performance, web scraping, and automation testing for modern web applications.
The Selenium headless browser automation library enables full web automation control, and one of these automation tasks is scrolls. In this guide, we'll explain using Python selenium scroll to element. Let's get started!
Let's start with the installation process. We'll be using the below packages:
pip
command:pip install selenium webdriver-manager
Next, use the webdriver-amanger
to automatically download the Selenium web driver:
from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()))
The above script will install the Chrome browser driver. However, other browsers are supported. See the official documentation for the available engines.
To scroll into a specific element using Sleneium, we can follow the below steps:
scrollIntoView
method with the selected HTML elementLet's apply the above steps within our Python Selenium code:
import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.chrome.service import Service as ChromeService
driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()))
driver.get("https://web-scraping.dev/product/1")
# scroll to an element at the bottom of the page
element = driver.find_element(By.CSS_SELECTOR, 'footer')
# execute scrollIntoView script with our element as the argument:
driver.execute_script(
"arguments[0].scrollIntoView({ behavior: 'smooth', block: 'end', inline: 'end' });",
element
)
time.sleep(5) # observe the new view
driver.close() # close the browser
Above, we start by selecting a web element at the bottom of them page using CSS selectors. Then, we use the execute_script
method to execute JavaScript code to scroll to the element the scrollIntoView
function. We also specify block and inline arguments to end
value to scroll to the bottom of the horizontal right of the element - this ensures highest visibility of the element. For more see browser's scrollIntoView documentation.
