Switch to an iframe through Selenium and python

How would I switch to this iframe in selenium knowing only

<iframe name="Dialogue Window">

You can use an XPath to locate the <iframe>:

iframe = driver.find_element_by_xpath("//iframe[@name='Dialogue Window']")

Then switch_to the <iframe>:

driver.switch_to.frame(iframe)

Here's how to switch back to the default content (out of the <iframe>):

driver.switch_to.default_content()

As per the HTML of the <iframe> element, it has the name attribute set as Dialogue Window. So to switch within the <iframe> you need to use the switch_to() method and you can use either of the following approaches:

• Using the name attribute of the <iframe> node as follows:

  # driver.switch_to.frame(‘frame_name’)
  driver.switch_to.frame("Dialogue Window")
  

• Using the <iframe> WebElement identified through name attribute as follows:

  driver.switch_to.frame(driver.find_element_by_name('Dialogue Window'))
  

• Using the <iframe> WebElement identified through css-selectors as follows:

  driver.switch_to.frame(driver.find_element_by_css_selector("iframe[name='Dialogue Window']"))
  

• Using the <iframe> WebElement identified through xpath as follows:

  driver.switch_to.frame(driver.find_element_by_css_selector("//iframe[@name='Dialogue Window']"))
  

• Ideally, you should induce WebDriverWait inconjunction with expected_conditions as frame_to_be_available_and_switch_to_it() for the desired frame as follows:

  • Using NAME:

    WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.NAME,"Dialogue Window"))) 
    

  • Using CSS_SELECTOR:

    WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[name='Dialogue Window']")))
    

  • Using XPATH:

    WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@name='Dialogue Window']")))
    

• To switch back to the Parent Frame you can use the following line of code:

  driver.switch_to.parent_frame()
  

• To switch back to the Top Level Browsing Context / Top Window you can use the following line of code:

  driver.switch_to.default_content()
