[Selenium] Open the link in a new tab and move it [Python / Chrome Driver]

Do you operate the browser?

Do you operate the same browser every day?

Let's leave such browser operation to Selenium!

Would you like to Ctrl + click a link to open it in a new tab while touching your browser? I do very well w

It will be such a series of flow.

Open and move the link in a new tab

sample.py

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait

import platform

driver = webdriver.Chrome("chromedriver.exe") #chromedriver.exe load

#
#
#Processing up to the corresponding page
#
#

#Element to click
element = driver.find_element_by_xpath('/html/body/hogehoge')
#element = driver.find_element_by_link_text("hogehoge") #Click here if you want to get it with link text

#Handle list before clicking
handles_befor = driver.window_handles

#(Link)Open element in new tab
actions = ActionChains(driver)

if platform.system() == 'Darwin':
    #Command key because it is a Mac
    actions.key_down(Keys.COMMAND)
else:
    #Control key because it is not a Mac
    actions.key_down(Keys.CONTROL)

actions.click(element)
actions.perform()

#Wait up to 30 seconds for new tabs to open
WebDriverWait(driver, 30).until(lambda a: len(driver.window_handles) > len(handles_befor))

#Handle list after clicking
handles_after = driver.window_handles

#Handle list diff
handle_new = list(handles_after - sethandles_befor)

#Go to new tab
driver.switch_to.window(handle_new[0])

Be careful not to overload Let's put wait and sleep as appropriate.

Commentary

sample.py

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait

Load the Selenium library and the packages you need this time.

sample.py

import platform

Load the library to determine the OS.

sample.py

driver = webdriver.Chrome("chromedriver.exe") #chromedriver.exe load

#
#
#Processing up to the corresponding page
#
#

Let's start the chrome driver and operate it.

sample.py

#Element to click
element = driver.find_element_by_xpath('/html/body/hogehoge')
#element = driver.find_element_by_link_text("hogehoge") #Click here if you want to get it with link text

Assign the element you click with xpath or link_text to a variable.

sample.py

#Handle list before clicking
handles_befor = driver.window_handles

Gets the handle in list format before the new tab opens.

sample.py

#(Link)Open element in new tab
actions = ActionChains(driver)

if platform.system() == 'Darwin':
    #Command key because it is a Mac
    actions.key_down(Keys.COMMAND)
else:
    #Control key because it is not a Mac
    actions.key_down(Keys.CONTROL)

actions.click(element)
actions.perform()

You can use a class called ʻActionChains` to record and execute keystrokes. On Mac and other operating systems, the shortcut key that opens in a new tab is different for the Google Chrome browser.

Mac: command + click Windows and Linux: Ctrl + click

The OS is judged by the platform library and conditional branching is performed.

ʻThe key operation recorded by actions.perform () `is executed.

sample.py

#Wait up to 30 seconds for new tabs to open
WebDriverWait(driver, 30).until(lambda a: len(driver.window_handles) > len(handles_befor))

It may take some time when a new tab opens, so let it wait. WebDriverWait (driver, 30)). until will allow the driver to wait up to 30 seconds.

In lambda a: len (driver.window_handles)> len (handles_befor), it is described in one line using a lambda expression.

len (handles_befor) than the number of handles before opening in a new tab len (driver.window_handles) The wait will be canceled when the number of handles exceeds the number of handles at the moment when a new tab is opened.

sample.py

#Handle list after clicking
handles_after = driver.window_handles

Gets the handle in list format after the new tab opens.

sample.py

#Handle list diff
handle_new = list(handles_after - handles_befor)

You can get the difference by subtracting the list with -. I'm assigning it to a variable.

sample.py

#Go to new tab
driver.switch_to.window(handle_new[0])

The difference handle_new [0] becomes the handle of the new tab, so move it with switch_to.window.

bonus

So that you can always go back if you open too many tabs and don't understand why (Let's not do that w)

It may be good to get the current handle in advance.

sample.py

#Current window(tab)Substitute the handle of
current_handle = driver.current_window_handle

#
#
#processing
#
#

#Current window(tab)Move to
driver.switch_to.window(current_handle)

Thank you very much!
