问题
Once a browser page is loaded I'm looking to use the CRTL+P shortcut in Goggle Chrome to enter the print page and then simply press return to print the page.
import time
from selenium import webdriver
# Initialise the webdriver
chromeOps=webdriver.ChromeOptions()
chromeOps._binary_location = "C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe"
chromeOps._arguments = ["--enable-internal-flash"]
browser = webdriver.Chrome("C:\\Program Files\\Google\\Chrome\\Application\\chromedriver.exe", port=4445, chrome_options=chromeOps)
time.sleep(3)
# Login to Webpage
browser.get('www.webpage.com')
My question is how do I send keys to the browser itself rather than an element?
Failed Attempt: To assign the html body to as the element and send keys to that-
elem = browser.find_element_by_xpath("/html/body") # href link
elem.send_keys(Keys.CONTROL + "P") # Will open a second tab
time.sleep(3)
elem.send_keys(Keys.RETURN)
回答1:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
browser.get('https://www.myglenigan.com/project_search_results.aspx?searchId='+ID)
element=browser.find_element_by_xpath("//body")
element.send_keys(Keys.CONTROL, 'p')
Just a note, this will open Firefox print panel. But the same code will not work in Goggle Chrome.
回答2:
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
ActionChains(browser).send_keys(Keys.CONTROL, "p").perform()
that would send the keyboard shortcut for a print dialog
I haven't found a way to do this in FF for printing though - ctrl+p will open the print dialog, but FF has a focus bug that doesn't allow one to do Keys.ENTER for the dialog itself
hopefully this will work for you in Chrome, I haven't tested it there
please update if you find a way around this - possibly try AutoIt
If none of the above works you can always do
browser.get_screenshot_as_file( path + 'page_image.jpg' )

If i understood your question correctly my suggestion is that you install and use the pyautogui module to make your python program press keys
For example:
import pyautogui
pyautogui.hotkey('ctrl','p')
see the pyautogui documentation for more information: https://pyautogui.readthedocs.io/en/latest/introduction.html

I have tested this on Google Chrome and the problem can be solved using a combination of .key_down() and .send_keys() methods of the ActionChains class.
ActionChains(driver).key_down(Keys.CONTROL).send_keys('p').key_up(Keys.CONTROL).perform()
ActionChains(driver).send_keys(Keys.ENTER)
