無法使用seleniumpython訪問PopUp/iframe視窗

我對硒很陌生。我正在使用 selenium python 處理自動結帳腳本。腳本執行非常順利，直到最后的結帳頁面。但是，我無法訪問最后一頁（“Razorpay Checkout”）上的元素，這是一種彈出/iframe 視窗。任何訪問相同的幫助將不勝感激。提前致謝！

下面是我正在使用的代碼

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('[email protected]')
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()

下面是錯誤

回溯（最近一次通話最后）：

檔案“C:\Users\hamhatre\Desktop\Algotron\WebScrap_Sample.py”，第 47 行，在 <module> driver.find_element_by_id('language-dropdown').click()

檔案“C:\Users\hamhatre\Anaconda3\lib\site-packages\selenium\webdriver\remote\webdriver.py”，第 360 行，在 find_element_by_id return self.find_element(by=By.ID, value=id_)

檔案“C:\Users\hamhatre\Anaconda3\lib\site-packages\selenium\webdriver\remote\webdriver.py”，第 976 行，在 find_element 回傳 self.execute(Command.FIND_ELEMENT, {

檔案“C:\Users\hamhatre\Anaconda3\lib\site-packages\selenium\webdriver\remote\webdriver.py”，第 321 行，執行 self.error_handler.check_response(response)

檔案“C:\Users\hamhatre\Anaconda3\lib\site-packages\selenium\webdriver\remote\errorhandler.py”，第 242 行，在 check_response 中引發 exception_class（訊息、螢屏、堆疊跟蹤）

NoSuchElementException：沒有這樣的元素：無法找到元素：{“method”：“css selector”，“selector”：“[id="language-dropdown"]"}（會話資訊：chrome = 99.0.4844.84）

uj5u.com熱心網友回復：

我正在使用 chromedriver 版本 100。您的代碼會拋出NoSuchElementException. 那是因為您的驅動程式試圖找到一個不存在的元素。所以，你需要做的是time.sleep(4)在你的陳述句之后放置陳述句click()（你的瀏覽器需要時間來打開視窗）。如果您使用完驅動程式，請使用driver.quit().

以下代碼對我有用：

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('[email protected]')
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()

uj5u.com熱心網友回復：

您可以在下一個專案中做的一些事情：

• 用于WebDriverWait為加載元素留出足夠的時間
• switch_to.default_content()在切換到另一幀之前使用
• 在切換幀時使用 time.sleep()
• 嘗試使用相對 xpath（例如：）//div[@id="user_address"]。右鍵單擊并從檢查視窗復制元素的絕對 xpath 很容易，但是如果中間添加了另一個元素，您的 xpath 將不再指向所需的元素。此外，相對 xpath 將使您能夠更深入地理解，從而使您可以輕松找到元素。

此代碼應該可以作業：
