#4

Scroll bar to the bottom

#5

from selenium import webdriver
import time

browser = webdriver.Chrome()
browser.get(‘http://www.sina.com.cn’)
browser.maximize_window()

time.sleep(3)

#1

js = ‘window.scrollTo(0,1000)’
browser.execute_script(js)
time.sleep(5)


#2

js = ‘window.scrollBy(0,300)’
browser.execute_script(js)
time.sleep(5)

#3

js = ‘window.scrollBy(0,300)’
browser.execute_script(js)
time.sleep(5)

#4

js = ‘window.scrollTo(0, document.body.scrollHeight)’
browser.execute_script(js)
time.sleep(5)

#5

js = ‘window.scrollTo(0,0)’
browser.execute_script(js)

2. scrollIntoView() and scrollIntoView(false） Method

time.sleep(3)

#1

element = browser.find_element_by_xpath(’//*[@id=“SI_Order_L”]/div/div[1]/div/span[1]/a’)

#2

browser.execute_script(‘arguments[0].scrollIntoView()’, element)
time.sleep(3)

#2

Press 5 Time Page_Up key

Press End Key to return to the bottom

#4

Press Home Key to return to the top

from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.keys import Keys

import time

browser = webdriver.Chrome()

browser.maximize_window()

browser.get(‘http://www.sina.com.cn’)

time.sleep(2)

#1

for i in range(5):
ActionChains(browser).key_down(Keys.PAGE_DOWN).key_up(Keys.PAGE_DOWN).perform()
time.sleep(2)

#2

for i in range(5):
ActionChains(browser).key_down(Keys.PAGE_UP).key_up(Keys.PAGE_UP).perform()
time.sleep(1)

#3

ActionChains(browser).key_down(Keys.END).key_up(Keys.END).perform()
time.sleep(2)

#4

ActionChains(browser).key_down(Keys.HOME).key_up(Keys.HOME).perform()

4. JS Of scrollTop() Method

#1

Variable value is 1000, Indicates scrolling to the bottom .

#2

Variable value is 0, Means to scroll to the top

from selenium import webdriver
