selenium.common.exceptions.NoSuchWindowException: Message: no such window error clicking an element within an iframe using Selenium and Python

问题

I'm starting with Selenium and have a question, basically I don't understand why when I switch to an iframe and select one of the elements I constantly get:

selenium.common.exceptions.NoSuchWindowException: Message: no such window
  (Session info: chrome=84.0.4147.89)

This is the relevan code, firstly I click on some element of the DOM containing the iframe that actually updates the iframe content and then select the iframe, switch to it and then select the element I want inside the HTML content of the iframe

# Select the item on main DOM that will udpate the iframe contents
bandeja = driver.find_element_by_xpath("//*[@id='sm20']")
bandeja.click()
# Tried sleeping, but also WedDriverWait to no avails...
time.sleep(3)
# Get the frame that actually has the content
frame = driver.find_element(by=By.NAME, value="ifrInterior")
driver.switch_to.frame(frame)
# Select the element inside the iframe and click
equipo = driver.find_element_by_xpath("//input[@name='gestionesPropias_Equipo']")
equipo.click()

Now if I debug this, I don't get the error above, and I can see there element has been selected...but upon click nothing happens

This is the expected element, even checked the screenshot in base64 and it looks ok, it's a radio input button...just wondering why click doesn't work??

UPDATE: Based on response from @DebanjanB I used his sugestion and this works but the button does not get clicked

Upon clicking there should a new drop down be enabled

This is the radio button:

When clicked this drop-down is enabled:

The relevant code about this element

<span id="filtroAsignado" class="W30">
            
    <select name="nuumaAsignado" class="W84">       
        <option value="">[Todo mi equipo]</option></select>
            
</span>

So now I wonder why this does not get clicked?

回答1:

As the desired element is within an <iframe> so you have to:

Induce WebDriverWait for the desired frame to be available and switch to it.
Induce WebDriverWait for the desired element to be clickable.
You can use the following xpath based Locator Strategy:

Using CSS_SELECTOR:

# Select the item on main DOM that will udpate the iframe contents
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#sm20"))).click()
# Don't sleep, but only WedDriverWait...
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[value='ifrInterior']")))
# Select the element inside the iframe and click
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[name='gestionesPropias_Equipo']"))).click()

Using XPATH:

# Select the item on main DOM that will udpate the iframe contents
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//*[@id='sm20']"))).click()
# Don't sleep, but only WedDriverWait...
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@value='ifrInterior']")))
# Select the element inside the iframe and click
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@name='gestionesPropias_Equipo']"))).click()

Note : You have to add the following imports :

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
