How Can I Scroll Web Pages Using Selenium WebDriver in Python?

Scrolling Web Pages with Selenium Webdriver in Python

When accessing web pages with dynamically loaded content, such as Facebook friends lists, scrolling is often necessary to retrieve all available data. Selenium Webdriver provides a range of methods to enable scrolling in Python.

Solution 1: Explicitly Scrolling Defined Distance

To scroll to a specific vertical position, utilize the following syntax:

driver.execute_script("window.scrollTo(0, Y)")

Replace Y with the desired scroll height, typically 1080 for a full HD monitor.

Solution 2: Scrolling to Page Bottom

To scroll to the bottom of the page:

driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")

Solution 3: Scrolling Pages with Infinite Loading

For social media platforms like Facebook with infinite scrolling:

SCROLL_PAUSE_TIME = 0.5

# Get initial scroll height
last_height = driver.execute_script("return document.body.scrollHeight")

while True:
    # Scroll down to bottom
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")

    # Pause to allow loading
    time.sleep(SCROLL_PAUSE_TIME)

    # Check if scroll height has changed
    new_height = driver.execute_script("return document.body.scrollHeight")
    if new_height == last_height:
        break
    last_height = new_height

Solution 4: Using Keyboard Shortcuts

Identify an element and apply the following:

label.sendKeys(Keys.PAGE_DOWN)
