无法使用selenium访问Pop Up / iframe窗口

Question

我对硒很陌生。我正在使用selenium编写一个自动结帐单。脚本执行非常顺利，直到最后签出页。但是，我无法访问最后一页上的元素(‘Razorpay Checkout')，这是一种弹出/iframe窗口。任何帮助访问同样的将是非常感谢的。提前感谢！

下面是我正在使用的代码

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

driver = webdriver.Chrome('C:/Users/hamhatre/Desktop/chromedriver.exe')
driver.get("https://shopatsc.com/collections/playstation-5/products/ps5-horizon-forbidden-west")
driver.maximize_window()
driver.implicitly_wait(20)
elem = driver.find_element_by_xpath('//*[@id="pincode_input"]')
elem.send_keys("400708")
driver.find_element_by_xpath('//*[@id="check-delivery-submit"]').click()
driver.find_element_by_xpath('/html/body/div[2]/main/div[1]/div/div/div/div[2]/div[1]/form/div[3]/div/button[2]').click()
driver.find_element_by_xpath('//*[@id="checkout_email"]').send_keys('abc@gmail.com')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_first_name"]').send_keys('abc')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_last_name"]').send_keys('xyz')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_address1"]').send_keys('Rd1, Flat no 2, Apt 1')
driver.find_element_by_xpath(('//*[@id="checkout_shipping_address_address2"]')).send_keys('Nothing')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_city"]').send_keys('Mumbai')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_province"]').send_keys('Maharashtra')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_zip"]').send_keys('400708')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_phone_custom"]').send_keys('9876543210')

driver.find_element_by_id('continue_to_shipping_button_custom').click()
driver.find_element_by_id('continue_button').click()
driver.find_element_by_xpath('/html/body/div/div/div/main/div[1]/div/form/div[3]/div[1]/button').click()


print(driver.title)
seq = driver.find_elements_by_tag_name('iframe')
print(seq)
print("No of frames present in the web page are: ", len(seq))


for index in range(len(seq)):
    iframe = driver.find_elements_by_tag_name('iframe')[index]
    driver.switch_to.frame(iframe)
    driver.find_element_by_id('language-dropdown').click()

下面是错误

Answer 1

我正在使用色度驱动器版本100。您的代码抛出一个NoSuchElementException。这是因为您的驱动程序试图找到一个不存在的元素。因此，您需要做的是将time.sleep(4)语句放在click()语句之后(浏览器需要时间打开窗口/s)。如果您已经使用完驱动程序，请使用driver.quit()。

遵循的代码适用于我：

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

driver = webdriver.Chrome('C:/Users/hamhatre/Desktop/chromedriver.exe')
driver.get("https://shopatsc.com/collections/playstation-5/products/ps5-horizon-forbidden-west")
driver.maximize_window()
driver.implicitly_wait(20)
elem = driver.find_element_by_xpath('//*[@id="pincode_input"]')
elem.send_keys("400708")
driver.find_element_by_xpath('//*[@id="check-delivery-submit"]').click()
driver.find_element_by_xpath('/html/body/div[2]/main/div[1]/div/div/div/div[2]/div[1]/form/div[3]/div/button[2]').click()
driver.find_element_by_xpath('//*[@id="checkout_email"]').send_keys('abc@gmail.com')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_first_name"]').send_keys('abc')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_last_name"]').send_keys('xyz')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_address1"]').send_keys('Rd1, Flat no 2, Apt 1')
driver.find_element_by_xpath(('//*[@id="checkout_shipping_address_address2"]')).send_keys('Nothing')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_city"]').send_keys('Mumbai')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_province"]').send_keys('Maharashtra')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_zip"]').send_keys('400708')
driver.find_element_by_xpath('//*[@id="checkout_shipping_address_phone_custom"]').send_keys('9876543210')

driver.find_element_by_id('continue_to_shipping_button_custom').click()
time.sleep(4)
driver.find_element_by_id('continue_button').click()
time.sleep(4)
driver.find_element_by_xpath('/html/body/div/div/div/main/div[1]/div/form/div[3]/div[1]/button').click()
time.sleep(4)


print(driver.title)
seq = driver.find_elements_by_tag_name('iframe')
print(seq)
print("No of frames present in the web page are: ", len(seq))


for index in range(len(seq)):
    iframe = driver.find_elements_by_tag_name('iframe')[index]
    driver.switch_to.frame(iframe)
    driver.find_element_by_id('language-dropdown').click()

Answer 2

在下一个项目中你可以做几件事：

• 使用WebDriverWait允许足够的时间来加载元素，
• 在切换到另一个框架之前使用switch_to.default_content()，
• 使用time.sleep()，而切换框架
• 尝试使用相对xpath(例如：//div[@id="user_address"])。从检查窗口右键单击并复制元素的绝对xpath很容易，但是如果其中添加了另一个元素，那么xpath将不再指向所需的元素。此外，相对xpath将使您能够更深入地了解元素，从而轻松地找到元素。

这一守则应适用于：

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

driver.get("https://shopatsc.com/collections/playstation-5/products/ps5-horizon-forbidden-west")
driver.maximize_window()

wait = WebDriverWait(driver, 20)


wait.until(EC.presence_of_element_located((By.XPATH, '//input[@id="pincode_input"]'))).send_keys('400708')

        print('Switching to frame')
        driver.switch_to.frame(iframes[frameno])
        time.sleep(2)
        wait.until(EC.presence_of_element_located((By.XPATH, '//div[@id="language-dropdown"]/div/div'))).click()
        found = True
        print('Found and clicked')
        
    except StaleElementReferenceException:
        print("Exception occured. Capturing iframes again")
        driver.switch_to.default_content()
        iframes = wait.until(EC.presence_of_all_elements_located((By.TAG_NAME, 'iframe')))
        
    except Exception as ex:
        print("Couldn't find/click on the language dropdown")
        frameno += 1
        
    finally:
        print('Switching to default content')
        driver.switch_to.default_content()
        time.sleep(2)
        tries += 1
