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

你可以使用

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

其中Y是高度(在全高清显示器上是1080)。(感谢@lukeis)

你也可以使用

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

滚动到页面底部。

如果你想滚动到一个无限加载的页面，比如社交网络，facebook等(感谢@Cuong Tran)

SCROLL_PAUSE_TIME = 0.5

# Get 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);")

    # 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.body.scrollHeight")
    if new_height == last_height:
        break
    last_height = new_height

另一种方法(感谢Juanse)是，选择一个对象和

label.sendKeys(Keys.PAGE_DOWN);

ScrollTo()函数不再工作。这是我用过的，效果很好。

driver.execute_script("document.getElementById('mydiv').scrollIntoView();")

滚动到元素:使用下面的代码找到元素并滚动。

scroll_element = driver.find_element(By.XPATH, "your element xpath")
driver.execute_script("arguments[0].scrollIntoView();", scroll_element)

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)

如果你想滚动到无限页面的底部(如linkedin.com)，你可以使用下面的代码:

SCROLL_PAUSE_TIME = 0.5

# Get 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);")

    # 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.body.scrollHeight")
    if new_height == last_height:
        break
    last_height = new_height
