我发现解决这个问题的最简单的方法是选择一个标签，然后发送:

label.sendKeys(Keys.PAGE_DOWN);

希望它有用!

这段代码滚动到底部，但不需要每次都等待。它会不断滚动，然后在底部停止(或超时)

from selenium import webdriver
import time

driver = webdriver.Chrome(executable_path='chromedriver.exe')
driver.get('https://example.com')

pre_scroll_height = driver.execute_script('return document.body.scrollHeight;')
run_time, max_run_time = 0, 1
while True:
    iteration_start = time.time()
    # Scroll webpage, the 100 allows for a more 'aggressive' scroll
    driver.execute_script('window.scrollTo(0, 100*document.body.scrollHeight);')

    post_scroll_height = driver.execute_script('return document.body.scrollHeight;')

    scrolled = post_scroll_height != pre_scroll_height
    timed_out = run_time >= max_run_time

    if scrolled:
        run_time = 0
        pre_scroll_height = post_scroll_height
    elif not scrolled and not timed_out:
        run_time += time.time() - iteration_start
    elif not scrolled and timed_out:
        break

# closing the driver is optional 
driver.close()

这比每次等待0.5-3秒的响应要快得多，因为每次响应可能需要0.1秒

方法如下图所示:

在python中，你可以使用

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

(Y为要滚动到的垂直位置)

当使用youtube时，浮动元素给出值“0”作为滚动高度 与其使用return document。body。scrollHeight"尝试使用这个"return document。documentelement。scrollHeight" 根据您的网速调整滚动暂停时间 否则它将只运行一次，然后在此之后中断。

SCROLL_PAUSE_TIME = 1

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

this dowsnt work due to floating web elements on youtube
"""

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

    # Wait to load page
    time.sleep(SCROLL_PAUSE_TIME)

    # Calculate new scroll height and compare with last scroll height
    new_height = driver.execute_script("return document.documentElement.scrollHeight")
    if new_height == last_height:
       print("break")
       break
    last_height = new_height

你可以使用send_keys来模拟PAGE_DOWN键(通常滚动页面):

from selenium.webdriver.common.keys import Keys
html = driver.find_element_by_tag_name('html')
html.send_keys(Keys.PAGE_DOWN)

如果你想在一个特定的视图/帧(WebElement)内滚动，你只需要用你想要滚动的特定元素替换“body”。在下面的例子中，我通过“getElementById”获得该元素:

self.driver.execute_script('window.scrollTo(0, document.getElementById("page-manager").scrollHeight);')

这就是YouTube上的例子……
