Open web in new tab Selenium + Python

Question

So I am trying to open websites on new tabs inside my WebDriver. I want to do this, because opening a new WebDriver for each website takes about 3.5secs using PhantomJS, I want more speed...

I'm using a multiprocess python script, and I want to get some elements from each page, so the workflow is like this:

Open Browser

Loop throught my array
For element in array -> Open website in new tab -> do my business -> close it

But I can't find any way to achieve this.

Here's the code I'm using. It takes forever between websites, I need it to be fast... Other tools are allowed, but I don't know too many tools for scrapping website content that loads with JavaScript (divs created when some event is triggered on load etc) That's why I need Selenium... BeautifulSoup can't be used for some of my pages.

def getPhantomData(parameters):
    try:
        # We create WebDriver
        browser = webdriver.Firefox()
        # Navigate to URL
        browser.get(parameters['target_url'])
        # Find all links by Selector
        links = browser.find_elements_by_css_selector(parameters['selector'])

        result = []
        for link in links:
            # Extract link attribute and append to our list
            result.append(link.get_attribute(parameters['attribute']))
        browser.close()
        browser.quit()
        return json.dumps({'data': result})
    except Exception, err:
        browser.close()
        browser.quit()
        print err

def callback(ch, method, properties, body):
    parameters = json.loads(body)
    message = getPhantomData(parameters)

    if message['data']:
        ch.basic_ack(delivery_tag=method.delivery_tag)
    else:
        ch.basic_reject(delivery_tag=method.delivery_tag, requeue=True)

def consume():
    credentials = pika.PlainCredentials('invitado', 'invitado')
    rabbit = pika.ConnectionParameters('localhost',5672,'/',credentials)
    connection = pika.BlockingConnection(rabbit)
    channel = connection.channel()

    # Conectamos al canal
    channel.queue_declare(queue='com.stuff.images', durable=True)
    channel.basic_consume(callback,queue='com.stuff.images')

    print ' [*] Waiting for messages. To exit press CTRL^C'
    try:
        channel.start_consuming()
    except KeyboardInterrupt:
        pass

workers = 5
pool = multiprocessing.Pool(processes=workers)
for i in xrange(0, workers):
    pool.apply_async(consume)

try:
    while True:
        continue
except KeyboardInterrupt:
    print ' [*] Exiting...'
    pool.terminate()
    pool.join()

Editor's note: This answer no longer works for new Selenium versions. Refer to this comment.

You can achieve the opening/closing of a tab by the combination of keys COMMAND + T or COMMAND + W (OSX). On other OSs you can use CONTROL + T / CONTROL + W.

In selenium you can emulate such behavior. You will need to create one webdriver and as many tabs as the tests you need.

Here it is the code.

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

driver = webdriver.Firefox()
driver.get("http://www.google.com/")

#open tab
driver.find_element_by_tag_name('body').send_keys(Keys.COMMAND + 't') 
# You can use (Keys.CONTROL + 't') on other OSs

# Load a page 
driver.get('http://stackoverflow.com/')
# Make the tests...

# close the tab
# (Keys.CONTROL + 'w') on other OSs.
driver.find_element_by_tag_name('body').send_keys(Keys.COMMAND + 'w') 


driver.close()

Answer 2

browser.execute_script('''window.open("http://bings.com","_blank");''')

Where browser is the webDriver

Answer 3

This is a common code adapted from another examples:

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

driver = webdriver.Firefox()
driver.get("http://www.google.com/")

#open tab
# ... take the code from the options below

# Load a page 
driver.get('http://bings.com')
# Make the tests...

# close the tab
driver.quit()

the possible ways were:

1. Sending <CTRL> + <T> to one element

   #open tab
   driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 't')
   

2. Sending <CTRL> + <T> via Action chains

   ActionChains(driver).key_down(Keys.CONTROL).send_keys('t').key_up(Keys.CONTROL).perform()
   

3. Execute a javascript snippet

   driver.execute_script('''window.open("http://bings.com","_blank");''')
   

   In order to achieve this you need to ensure that the preferences browser.link.open_newwindow and browser.link.open_newwindow.restriction are properly set. The default values in the last versions are ok, otherwise you supposedly need:

   fp = webdriver.FirefoxProfile()
   fp.set_preference("browser.link.open_newwindow", 3)
   fp.set_preference("browser.link.open_newwindow.restriction", 2)
   
   driver = webdriver.Firefox(browser_profile=fp)
   

   the problem is that those preferences preset to other values and are frozen at least selenium 3.4.0. When you use the profile to set them with the java binding there comes an exception and with the python binding the new values are ignored.

   In Java there is a way to set those preferences without specifying a profile object when talking to geckodriver, but it seem to be not implemented yet in the python binding:

   FirefoxOptions options = new FirefoxOptions().setProfile(fp);
   options.addPreference("browser.link.open_newwindow", 3);
   options.addPreference("browser.link.open_newwindow.restriction", 2);
   FirefoxDriver driver = new FirefoxDriver(options);
   

The third option did stop working for python in selenium 3.4.0.

The first two options also did seem to stop working in selenium 3.4.0. They do depend on sending CTRL key event to an element. At first glance it seem that is a problem of the CTRL key, but it is failing because of the new multiprocess feature of Firefox. It might be that this new architecture impose new ways of doing that, or maybe is a temporary implementation problem. Anyway we can disable it via:

fp = webdriver.FirefoxProfile()
fp.set_preference("browser.tabs.remote.autostart", False)
fp.set_preference("browser.tabs.remote.autostart.1", False)
fp.set_preference("browser.tabs.remote.autostart.2", False)

driver = webdriver.Firefox(browser_profile=fp)

... and then you can use successfully the first way.

# Switch back to the first tab
driver.switch_to.window(driver.window_handles[0])
driver.get("https://bing.com")
time.sleep(3)

# Close the only tab, will also close the browser.
driver.close()

Answer 5

In a discussion, Simon clearly mentioned that:

While the datatype used for storing the list of handles may be ordered by insertion, the order in which the WebDriver implementation iterates over the window handles to insert them has no requirement to be stable. The ordering is arbitrary.

Using Selenium v3.x opening a website in a New Tab through Python is much easier now. We have to induce an WebDriverWait for number_of_windows_to_be(2) and then collect the window handles every time we open a new tab/window and finally iterate through the window handles and switchTo().window(newly_opened) as required. Here is a solution where you can open http://www.google.co.in in the initial TAB and https://www.yahoo.com in the adjacent TAB:

• Code Block:

    from selenium import webdriver
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.support import expected_conditions as EC
  
    options = webdriver.ChromeOptions() 
    options.add_argument("start-maximized")
    options.add_argument('disable-infobars')
    driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
    driver.get("http://www.google.co.in")
    print("Initial Page Title is : %s" %driver.title)
    windows_before  = driver.current_window_handle
    print("First Window Handle is : %s" %windows_before)
    driver.execute_script("window.open('https://www.yahoo.com')")
    WebDriverWait(driver, 10).until(EC.number_of_windows_to_be(2))
    windows_after = driver.window_handles
    new_window = [x for x in windows_after if x != windows_before][0]
    driver.switch_to.window(new_window)
    print("Page Title after Tab Switching is : %s" %driver.title)
    print("Second Window Handle is : %s" %new_window)
  

• Console Output:

    Initial Page Title is : Google
    First Window Handle is : CDwindow-B2B3DE3A222B3DA5237840FA574AF780
    Page Title after Tab Switching is : Yahoo
    Second Window Handle is : CDwindow-D7DA7666A0008ED91991C623105A2EC4

Answer 6

The other solutions do not work for chrome driver v83.

Instead, it works as follows, suppose there is only 1 opening tab:

driver.execute_script("window.open('');")
driver.switch_to.window(driver.window_handles[1])
driver.get("https://www.example.com")

If there are already more than 1 opening tabs, you should first get the index of the last newly-created tab and switch to the tab before calling the url (Credit to tylerl) :

driver.execute_script("window.open('');")
driver.switch_to.window(len(driver.window_handles)-1)
driver.get("https://www.example.com")

Answer 7

Try this it will work:

# Open a new Tab
driver.execute_script("window.open('');")

# Switch to the new window and open URL B
driver.switch_to.window(driver.window_handles[1])
driver.get(tab_url)

Answer 8

After struggling for so long the below method worked for me:

driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 't')
driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + Keys.TAB)

windows = driver.window_handles

time.sleep(3)
driver.switch_to.window(windows[1])

Answer 9

from selenium import webdriver
import time

driver = webdriver.Firefox()
driver.get('https://www.google.com')

driver.execute_script("window.open('');")
time.sleep(5)

driver.switch_to.window(driver.window_handles[1])
driver.get("https://facebook.com")
time.sleep(5)

driver.close()
time.sleep(5)

driver.switch_to.window(driver.window_handles[0])
driver.get("https://www.yahoo.com")
time.sleep(5)

#driver.close()

Answer 10

just for future reference, the simple way could be done as this:

driver.switch_to.new_window()
t=driver.window_handles[-1]# Get the handle of new tab
driver.switch_to.window(t)
driver.get(target_url) # Now the target url is opened in new tab

Answer 11

Strangely, so many answers, and all of them are using surrogates like JS and keyboard shortcuts instead of just using a selenium feature:

def newTab(driver, url="about:blank"):
    wnd = driver.execute(selenium.webdriver.common.action_chains.Command.NEW_WINDOW)
    handle = wnd["value"]["handle"]
    driver.switch_to.window(handle)
    driver.get(url) # changes the handle
    return driver.current_window_handle

Answer 12

I'd stick to ActionChains for this.

Here's a function which opens a new tab and switches to that tab:

import time
from selenium.webdriver.common.action_chains import ActionChains

def open_in_new_tab(driver, element, switch_to_new_tab=True):
    base_handle = driver.current_window_handle
    # Do some actions
    ActionChains(driver) \
        .move_to_element(element) \
        .key_down(Keys.COMMAND) \
        .click() \
        .key_up(Keys.COMMAND) \
        .perform()
    
    # Should you switch to the new tab?
    if switch_to_new_tab:
        new_handle = [x for x in driver.window_handles if x!=base_handle]
        assert len new_handle == 1 # assume you are only opening one tab at a time
        
        # Switch to the new window
        driver.switch_to.window(new_handle[0])

        # I like to wait after switching to a new tab for the content to load
        # Do that either with time.sleep() or with WebDriverWait until a basic
        # element of the page appears (such as "body") -- reference for this is 
        # provided below
        time.sleep(0.5)        

        # NOTE: if you choose to switch to the window/tab, be sure to close
        # the newly opened window/tab after using it and that you switch back
        # to the original "base_handle" --> otherwise, you'll experience many
        # errors and a painful debugging experience...

Here's how you would apply that function:

# Remember your starting handle
base_handle = driver.current_window_handle

# Say we have a list of elements and each is a link:
links = driver.find_elements_by_css_selector('a[href]')

# Loop through the links and open each one in a new tab
for link in links:
    open_in_new_tab(driver, link, True)
    
    # Do something on this new page
    print(driver.current_url)
    
    # Once you're finished, close this tab and switch back to the original one
    driver.close()
    driver.switch_to.window(base_handle)
    
    # You're ready to continue to the next item in your loop

Here's how you could wait until the page is loaded.

Answer 13

you can use this to open a new tab

driver.execute_script("window.open('http://google.com', 'new_window')")

Answer 14

This worked for me:-

link = "https://www.google.com/"
driver.execute_script('''window.open("about:blank");''')  # Opening a blank new tab
driver.switch_to.window(driver.window_handles[1])  # Switching to newly opend tab
driver.get(link)

Answer 15

The 4.0.0 version of Selenium supports the following operations:

• to open a new tab try:

  driver.switch_to.new_window()

• to switch to a specific tab (note that the tabID starts from 0):

  driver.switch_to.window(driver.window_handles[tabID])
