[python] How to switch to new window in Selenium for Python?

I am working on selenium automation project using Python.

I am facing an issue, which is handling multiple browser windows.

Scenario is as follows. When I click a link on the home page, a new window opens. In the newly opened window I cannot perform any actions, because the focus is still on the home page web driver.

Can anybody show me how to change focus from the background window to the newly opened window?

A possible solution is driver.switch_to.window(), but it requires the window's name. How to find out the window's name? If this is a wrong way to do this, can anybody give some code examples to perform this action?

window_handles should give you the references to all open windows.

this is what the docu has to say about switching windows.

for eg. you may take

driver.get('https://www.naukri.com/')

since, it is a current window ,we can name it

main_page = driver.current_window_handle

if there are atleast 1 window popup except the current window,you may try this method and put if condition in break statement by hit n trial for the index

for handle in driver.window_handles:
    if handle != main_page:
        print(handle)
        login_page = handle
        break

driver.switch_to.window(login_page)

Now ,whatever the credentials you have to apply,provide after it is loggen in. Window will disappear, but you have to come to main page window and you are done

driver.switch_to.window(main_page)
sleep(10)

We can handle the different windows by moving between named windows using the “switchTo” method:

driver.switch_to.window("windowName")

<a href="somewhere.html" target="windowName">Click here to open a new window</a>

Alternatively, you can pass a “window handle” to the “switchTo().window()” method. Knowing this, it’s possible to iterate over every open window like so:

for handle in driver.window_handles:
    driver.switch_to.window(handle)

You can do it by using window_handles and switch_to_window method.

Before clicking the link first store the window handle as

window_before = driver.window_handles[0]

after clicking the link store the window handle of newly opened window as

window_after = driver.window_handles[1]

then execute the switch to window method to move to newly opened window

driver.switch_to_window(window_after)

and similarly you can switch between old and new window. Following is the code example

import unittest
from selenium import webdriver

class GoogleOrgSearch(unittest.TestCase):

    def setUp(self):
        self.driver = webdriver.Firefox()

    def test_google_search_page(self):
        driver = self.driver
        driver.get("http://www.cdot.in")
        window_before = driver.window_handles[0]
        print window_before
        driver.find_element_by_xpath("//a[@href='http://www.cdot.in/home.htm']").click()
        window_after = driver.window_handles[1]
        driver.switch_to_window(window_after)
        print window_after
        driver.find_element_by_link_text("ATM").click()
        driver.switch_to_window(window_before)

    def tearDown(self):
        self.driver.close()

if __name__ == "__main__":
    unittest.main()

On top of the answers already given, to open a new tab the javascript command window.open() can be used.

For example:

# Opens a new tab
self.driver.execute_script("window.open()")

# Switch to the newly opened tab
self.driver.switch_to.window(self.driver.window_handles[1])

# Navigate to new URL in new tab
self.driver.get("https://google.com")
# Run other commands in the new tab here

You're then able to close the original tab as follows

# Switch to original tab
self.driver.switch_to.window(self.driver.window_handles[0])

# Close original tab
self.driver.close()

# Switch back to newly opened tab, which is now in position 0
self.driver.switch_to.window(self.driver.window_handles[0])

Or close the newly opened tab

# Close current tab
self.driver.close()

# Switch back to original tab
self.driver.switch_to.window(self.driver.window_handles[0])

Hope this helps.
