如何使用 FirefoxOptions() 使用 Selenium/Python 放大/缩小 Firefox

Question

I want to maximize the window and zoom out to 0.8.

Here is the code:

from selenium import webdriver    
from selenium.webdriver.firefox.options import Options
profile = webdriver.FirefoxProfile()
options = webdriver.FirefoxOptions()
options.add_argument('--start-maximized') # not working
driver = webdriver.Firefox(firefox_profile=profile, options=options, executable_path=r"W:\geckodriver.exe")
driver.execute_script('document.body.style.MozTransform = "scale(0.8)";') # not working

The window is not getting maximized nor zoomed out.

Answer 1

I used this instead:

#1st install pyautogui
import pyautogui
pyautogui.hotkey('ctrl', '-') #zooms out to 80%
pyautogui.hotkey('ctrl', '-')

Answer 2

Please try the following to zoom out to 0.8:

driver.execute_script("document.body.style.zoom='80%'")

You can use the following code to maximize:

driver.maximize_window()
