selenium - 无法使用 selenium Python 定位元素

Question

我正在尝试使用 Python 中的 Selenium 将信息输入到输入字段中。我无法找到到期日期和 CVV 字段。我知道它们在 iframe 中，但我只能正确输入信用卡号。其他一切都是空的。

这是我到目前为止所拥有的:

options = webdriver.ChromeOptions()
options.add_argument("start-maximized")
options.add_argument('disable-infobars')
driver = webdriver.Chrome(chrome_options=options)
driver.get("https://www.audiobooks.com/signup")
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@id='braintree-hosted-field-number']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='number' and @id='credit-card-number']"))).send_keys("1234567890987654")

WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@id='braintree-hosted-field-expirationDate']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='expirationDate' and @id='expirationDate']"))).send_keys("11/21")

WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@id='braintree-hosted-field-cvv']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='cvv' and @id='cvv']"))).send_keys("123")

要切换到下一个 iframe，您需要先切换回主 DOM。因此，只需在帧切换行之间添加以下代码:

driver.switch_to.default_content()

您的最终代码:

WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@id='braintree-hosted-field-number']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='number' and @id='credit-card-number']"))).send_keys("1234567890987654")

driver.switch_to.default_content()

WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@id='braintree-hosted-field-expirationDate']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='expirationDate' and @id='expiration']"))).send_keys("11/21")

driver.switch_to.default_content()

WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@id='braintree-hosted-field-cvv']")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='cvv' and @id='cvv']"))).send_keys("123")
